And how do I find myself - if I don’t even know who I am?

Crossposted on ao3 here

A Cal Weathers - centred fic, about his thoughts post-retirement.

Heavy Angst ahead just a PSA

And I- And I don’t know what to do.

I don’t know where to go from here.

When he wakes up he normally draws the blinds.

Today he doesn’t. He sits in the dark, gaze fixed absently on the covered window and letting just the sound of his breathing bleed out to fill the room.

It’s Sunday.

He should be racing.

Behind the wheel, fingers gripping onto it so tight it was like a lifeline, heart thudding, adrenaline pumping through his veins. Laughing and cursing as he pushes the car 200 around the turns. Shifting gears, yanking the brake, eyeing the mirror. Embracing the screams of the crowd, the roar of the engines, the asphalt that stretched ahead of him and-

He should be racing.

He isn’t.

His own words resurface in his mind. Two weeks prior feels like an eternity ago.

He can still remember it though, the helpless smile that had tugged at his lips, the half shrug he had offered, the icy despair that he had forced to slide off his spine and onto the floor. The creak and hiss of hydraulics as the hauler ramp is drawn up, Lightning slowly vanishing from sight. There had been a muted ‘thump’ as the door slid into place, and he had breathed out. Slow and steady even as tears pricked the corners of his eyes.

This is what you wanted.

Is it really what you wanted?

Two Saturdays Ago.

“You sure ‘bout this, Cal?” Tex’s southern drawl drags him out of his thoughts as his hand pauses over the paper, pen not quite touching the solid line just yet.

His throat dries.

He takes a long, deep breath.

“We can always get you a better car-” The rest of Tex’s words fade into the distance as he stares down at that empty blank. Memories of Sunday before flicker in his mind, far too glaring to ignore.

The car feels good as he grips the steering wheel tight. Yet- yet he watches Storm’s tail lights become dimmer and dimmer in the distance. The clean hum of next-gen engines haunts him, constantly ringing in his ears.

‘Hey Cal. Next week will be better. We’ll- We’ll figure it out.’ Strip’s voice filters over his earpieces, and he blinks.

‘It’s over?’ He can scarcely believe it. There’s a soft affirmation from his uncle, and the silent question of : do you want to know..? Lingers between them.

Bitterness suddenly rises from somewhere within him. At the way his uncle was acting, like he was a brittle piece of glass about to shatter. At the fact that he had tried so hard - that he had thought he had done well and-

He lets the car slow to a stop.

He’s pretty sure Strip can hear his ragged breathing, but he doesn’t say a word.

“Just tell me. I can take it,” he snaps, too harshly, he knows this. Yet the emotions roiling within him are so overwhelming. This is the best he can muster.

“...twenty eighth.”

Cal can hear the slightest of shakes in his uncle’s voice. His heart drops as guilt floods him, washing away whatever spite still remained.

“Okay.” He utters, because he has no strength to say anything else.

The blond forces himself to snap out of it. This is what mattered. Right now. This decision.

“Yes.” He says, and tries to make his voice sound strong.

“Alright kid,” The Dinoco tycoon opposite him relents, but he can see the sorrow in his eyes too. Cal resists the urge to click the pen in his hands.

He breathes out, all careful and composed.

“I’m sorry, Tex,” he finally says after a long beat of silence had stretched between them. He owes him this much - he owes him so much more.

“If you ever need anythin’... let me know,” he hears the older man say as he gets up. All he can offer is a tiny nod.

This was what you wanted.

…Why?

That day he returned home after leaving the circuits for good, he glimpsed one of his two Piston Cups, glittering innocently where it lay. His chest constricts painfully at the reminder, and he almost lets out some sort of twisted laugh. Everything seemed to remind him of racing. Of course.

Of course it did.

That’s just how it has always been, really. Racing… it ran in his blood. And he had been handling it fine. He had. Until now and everything in his body just aches, an unseen void somewhere deep within him. He had wanted to race so badly, but what was racing if there was no one left for you to race with on the track?

Surely this was better than having to race alone week upon week. Yet his heart had screamed to return to the track. To keep racing regardless of the result.

-No. Stop. He couldn’t second guess himself now. It’s too late.

Somewhere within him he had already accepted this. Because although he might not know himself that much he… he wouldn’t be happy. Not truly happy, racing in circumstances such as those.

So amidst all the warring emotions and thoughts clashing in his head he just stood there silently, staring at the way sunlight gleamed off gold. Yet never really looking at the gold at all.

Everything that day had been so agonisingly conflicting, with the unmistakable yearning in his heart to simply keep racing, and the sudden consuming loneliness.

His phone had rang, and his feet carried him to the source of the sound, purely through muscle memory. Cal had picked it up, taking a sharp breath to hopefully even out his breathing, before answering.

“Cal? How’re you doing, dear?” Lynda’s voice had filtered over the receiver, and he had almost shattered right there and then. Instead, he had dredged up enough strength to utter a ‘Doin’ alright.’ despite how obviously that had been a lie. A long silence on the other end had actually made him prepare for a scolding of sorts. He knew Lynda hated lying - yet what happened had been completely the opposite. “...Alright then, Cal.” He had heard the sadness in her words, quiet and hidden.

Cal had forced himself to keep his breathing even.

“Is Uncle there?” He had then asked, ignoring how his voice bordered on the edges of an exhausted rasp.

“Of course, dear- do you want to talk to him?”

Everything had told him to say yes, and still all that had slipped out of his mouth had been a succinct ‘no’.

Recalling it all now he realises he still remembered the questions that had surfaced in his mind. The things that he would have said, he should have said to his uncle.

He still doesn’t know why he had said no.

Maybe I just wanted so much to be someone else that-

I never had the chance to know who I wanted to be.

After that every day had become clockwork. Wake up bathed in darkness, unable to bring himself to draw the blinds, washing up, eating just a little. Feeding the cats, staring off into the distance and zoning out for definitely far too long to be considered healthy.

One of those days - he can’t remember when, time had been something he hadn’t bothered keeping track of - the cats had clambered up on his bed as he’d sat there listlessly.

They had been purring, a rumbling sound that seemed to fill the room, pushing just the slightest bits of life and reality back into him.

Cal had just broken down, he didn’t even know why, but shaking gasps had burst forth from his lips, a choking, strangled sound of unexplainable anguish. Fingers clutching desperately at the sheets for the feeling to ground him, drawing his knees up to his chest.

Alone in his room with no one but a few fluffy companions so much kinder than he had ever expected- Cal Weathers allows his world to crash down.

He wonders if this is part of the healing process. He sobs and wonders how healing is so hard.

Breathe in.

Breathe out.

Tell yourself you’re fine.

Say it out loud.

Today is slightly more stable.

Sure, he should be racing. And he isn’t.

But today, after looking back on it all. The wound is still rubbed tender and raw.

Maybe it’s time to do something else. The notion surfaces in his mind for the briefest of moments, and he- he thinks this is a good sign.

He hopes it’s a good sign.

He draws in a breath, lets it out slow. Repeats that. Over and over and over.

Cal swings his legs over the side of the bed and gets up. Every step to the window seems like it's weighed like lead. Still, it’s lighter than it was before.

He pauses before the blinds, shuttering his eyes. Focusing on the way his lungs filled and emptied ever so slowly.

Breathe carefully.

His eyes flit open as he tugs on the blinds. He allows sunlight to stream in and he thinks he feels just the slightest of warmth.

And maybe he’s getting there.

Cal picks up his phone and powers it on, swiping to the few contacts he has stored.

Another tentative breath.

Pawsteps echo in his doorway and he gives just a tiny smile to the calico lurking at the entrance of his room.

He makes the call and the dial tones hums - someone picks up.

For a moment there’s nothing but the sound of breathing.

“Hey Cal. Wanna go fishin’? If you’re… If you’re free, of course.” His uncle’s voice is gentler than he’s ever imagined, and his only response to the question is a watery laugh. It lingers in the morning air, soft and unrestrained.

“Okay.” He says. He thinks he’s getting there, ever so slowly. “I’m okay, Uncle Strip. I think.” He’s sure his uncle didn’t miss the way his voice cracked.

Yet his uncle says nothing, and he can hear a faint exhale, relieved, from his end. “You should call Emi. And Cal… I’m proud of you.” The older Weathers finally states, and Cal feels a warm flutter that he can’t quite name.

He breathes in and the morning air is fresher than before.

And maybe now there’s finally time to find out what I want to become.

AN : This was done completely on a whim lmao- but i figured it's been a long while since i posted this fic and hence this is a thing now. XD Hope you enjoyed- please reblog!!

What Is DTH Drilling

DTH drilling, also known as Down-The-Hole drilling, is a technique used in mining, construction, and exploration projects to drill holes in hard rock formations. It is a percussion drilling method that utilizes a pneumatic or hydraulic hammer, often referred to as a DTH hammer, to deliver powerful blows to the drill bit.

Here's how the DTH drilling process typically works:

Rig Setup: A drilling rig is set up at the desired location. The rig consists of a drill string, which includes drill pipes, a DTH hammer, and a drill bit. The rig is positioned vertically or at a suitable angle for the drilling operation.

Hammer Assembly: The DTH hammer is connected to the bottom end of the drill string. The hammer contains a piston that strikes the back of the drill bit, transmitting energy to the bit for breaking the rock.

Air or Fluid Supply: Compressed air or drilling fluid (usually water-based) is pumped down the drill string to the hammer. The air or fluid serves multiple purposes, including removing drill cuttings from the hole and providing the necessary force to operate the hammer.

Drilling Operation: When the air or fluid reaches the DTH hammer, it enters the hammer's internal chamber and applies pressure to the piston. The piston reciprocates rapidly, delivering powerful blows to the drill bit. The impact energy fractures the rock, while the cuttings are carried to the surface through the annular space between the drill string and the hole wall.

Hole Advancement: As the drilling progresses, the rig applies downward force to the drill string, allowing the bit to penetrate deeper. The process continues until the desired depth is reached.

DTH drilling offers several advantages, including high drilling efficiency, accurate hole straightness, and the ability to drill in various rock types. It is commonly used in applications such as mining exploration, quarrying, foundation drilling, water well drilling, and geotechnical investigations.

I also noticed something interesting within the Shrines. I’d assumed the orange constellation lights on the walls were just stationery lights, but I noticed something in the Bomb Rune dungeon. After you clear the second obstacle on the main path, you can get right up close to the wall to get a good look at a constellation. The lights inside aren’t stationary, but are actually a texture that “pulses” back and forth along with a strange noise that turns out to be the pistons that are launching the ball back and forth in the puzzle in the next room.

The constellations aren’t lights, they’re transparent channels that appear to be holding some kind of orange fluid that’s rhythmically shifting to power whatever mechanisms are running within the shrine. It’s almost like hydraulic power, where the forces and motions of the liquid are used to power machinery. It’s not just the little data crystals; all the Sheikah technology runs on liquid.

I mean, it makes sense in retrospect that the orange stuff is also liquid, but I’ve never actually seen the orange goo out in the open, so I didn’t think it existed. But, so far, it seems like the blue liquid is for data storage or other “passive” processes, while the orange is used for the hydraulic systems that “make things go,” which is why non-possessed Guardians shift from passive blue to active orange when they get ready to fight.

But it also implies something about the nature of Ganon’s control over the robots. Maybe he doesn’t technically need to hack into their little computer brains, but instead fill their hydraulic tubes with his own pink goo. Pink is the color of “full of Ganon.” If he’s in the hydraulic pipes, he can just force the machinery into the positions he wants by controlling the pressure flow and exerting/releasing enough pressure in the right spots. Maybe the actual “hacking” isn’t to actually force the machine to move, but simply to disable it to prevent physical resistance that could damage the body, or to give Ganon access to the robot’s audiovisual receptors so he can observe what’s going on and more precisely move his current vessel around.

Not to mention that Ganon seems to be able to convert his raw Malice-matter between liquid, gaseous, and solid states, which suggests he’s capable of pneumatic power in addition to hydraulic power. His taking over of corpses or living bodies could function the same way as those spider-corpse carnival crane experiments where the scientists got a spider corpse to move and grip things by pumping pressurized air through its legs. Or even like how the bacterial “corpse gas” was able to move the infected bodies and the biomechanical spider legs in Junji Ito’s Gyo! Gross! :D

Wanted to redo Eldoron’s reference sheet to be cleaner since I want to publish these as supplemental material. Want to clean up Trish’s and Jessie’s too while I get through a bit of artist block that is keeping me from finishing the rest of the main six.

Also wanted to finalize his design since the size and shape of his talons were inconsistent plus he had too many scales that would make drawing him too time consuming so cut those down by over half.

Fun facts about Eldoron;

1) He comes from an alien race of bird/human hybrids called Vimerians

2) Vimerians used to be light enough with larger wings allowing for autonomous flight, but over generations of evolution driven by atmospheric shifts. these abilities disappeared so they used powers of magic and tech in order to enjoy the skies again.

3) Eldoron like all males, possesses a biological hydraulic piston pump in the form of a separate circulatory system where he can voluntarily redirect blood causing his arms, hands, and claws to swell and harden to allow for extra strength and support. He can release this pressure in times where dexterity takes priority.

Hello. Can you do a quirk based on Henry Cavill reloading his arms in Mission Impossible Fallout. This isn't a prank or joke request, I just think it's a good visual for a shotgun arms quirk or something

Good Day/Evening, Quirkwizard. Would it be possible for you to do a Quirk on Jackhammer Arms?

While it certainly could work for a gun ability, I think it could be a disservice to that amazing scene if it was anything other than a fist Quirk. Something like Crossbone's Gauntlets from the MCU.

I see it working Mutant type Quirk alters the user's hands and forearms, making them large and metallic. This gives the user a set of hydraulics in their arms with a kind of piston in place of their elbow. When the user pumps their arm, they can pull back and then extend their arm out, unleashing a powerful attack on whatever they hit. This can cause immense damage, capable of demolishing concrete and sending minibuses flying. The user can divvy out this power, such as making a series of smaller attacks, beating into their foes like a jackhammer. The user can hold it for a brief time and can undo it by pumping their fist again. This gives the user a lot of offensive power, letting them unleash devastating moves with a single attack. They can dig their way through debris, fire off projectiles like a cannon, tear up the terrain to throw off their opponents, launch themselves into the air with the hydraulics, or just beat people up with piston fists. Aside from being limited to the arms, this does require the user to cock their arms each time they want to use this ability, potentially making them predictable with how they telegraph the attack. Applying the Quirk too much can end up with the hydraulics locking up, requiring a second for them to work again. A possible name for the Quirk could be "Fist Pump".

On August 19th 1808 James Nasmyth, the noted Scottish engineer, was born in Edinburgh.

James was sent to the Royal High School where he had as a friend, Jimmy Patterson, the son of a local iron founder. Being already interested in mechanics he spent much of his time at the foundry and there he gradually learned to work and turn in wood, brass, iron, and steel.

He left school at age twelve to make model engines and other mechanical devices. At nineteen he built a full-size steam carriage which performed with acclaim. When he was twenty-one, Nasmyth accompanied his father on a trip to London, England, where he met machinist and engineer Henry Maudslay. During the next two years, Nasmyth studied and worked under Maudslay, learning from him as well as making valuable contributions, such as designing hexagonal-headed nuts and a flexible shaft of coiled spring steel for drilling holes in awkward places.

In 1834, Nasmyth opened his own shop in Manchester, England, later moving to a foundry at Patricraft, England, where he became known for his craftsmanship and steam-powered tools. It was also here, in 1839, that he invented the steam hammer, a device that allowed large materials to be forged with great accuracy. The concept of the steam hammer was simple, even though the idea was totally new. A hammering block was hoisted by steam power to a vertical position above a piece of metal. Once the hammer reached an appropriate height, steam in the piston was released and the block fell. The pistons could be regulated not only in strength of blow, but also in frequency of strokes.

At the time, Nasmyth decided to postpone patenting, building, and marketing the new steam hammer. Two-and-a-half years later, however, while visiting a fellow machinist in France, Nasmyth was shown a steam hammer that had been built from his own rough sketches. Nasmyth quickly returned to England, patented his work, and manufactured hammers for an eager market. Soon he was making hammers with four-and five-ton blocks, and by 1843 he had improved on them by injecting steam above the piston to add force to the downward blow. The steam hammer allowed larger forgings with heavier metals, tightened bonds, and made metals stronger and more dense. Not surprisingly, Nasmyth soon revived a previous interest and became involved in manufacturing steam locomotives for various railway companies.

In fourteen years, he built 109 high-pressure steam engines, pumps, and hydraulic presses. His steam hammer was exhibited at the Great Exhibition of 1851 alongside his prize-winning maps of the moon. Nasmyth retired in 1856. He built a number of telescopes and charted sunspots as well as the surface of the moon. Nasmyth also devised a vertical cylinder-boring machine and milling machines.

He co-wrote The Moon : Considered as a Planet, a World, and a Satellite with James Carpenter. This book contains an interesting series of “lunar” photographs: because photography was not yet advanced enough to take actual pictures of the Moon, Nasmyth built plaster models based on his visual observations of the Moon and then photographed the models.

He died a financially successful inventor, unlike many of his peers, on May 7, 1890.

The first pic is by the famous duo Hill and Adamson, the second of his main invention the steam hammer

Prompt #10: “Channel” - FFXIV Write 2022

Evander should have been sourcing copper, but sourcing copper was a poor use of his time, a poorer use of his considerable creative talents, and most importantly, boring as shit. Instead, he'd been carving narrow grooves into thin panels of wood, assembling various pulleys, catapults and other small contraptions, repurposing half-finished models and clockwork devices, and meticulously measuring all sorts of dimensions around his apartment.

The first design involved dominoes, and while that was satisfying as hell, it wasn't terribly practical. What was he going to do, reset every domino every time? He just knew that within a day he'd be missing a few pieces because he had just slightly misjudged the force of some deadfall or zipline carriage, and it'd be even sooner than that when one of his pets decided to haul off a stray domino for some inscrutable purpose.

So dominoes were no good.

Mark II was intended to be all pulleys, levers, and for about 20 ill-advised minutes, a high-powered pneumatic pump.

Mark III was, for some reason, going to involve hydraulics. Evander still wasn't sure why he thought that was a good idea after the disaster that came from trying to incorporate simple (if overzealous) pneumatics.

Mark IV, though? He went back to basics and finally hit his stride. Now, thanks to yalms and yalms of carefully carved tracks and a seemingly inexhaustible supply of ball bearings from other projects, he could accomplish a startling array of household chores without leaving his desk. Send a glass marble down one channel and it would roll down the track he attached to his wall, picking up just enough velocity that it could flip a lever that would dump some scraps into the crab dish. It didn't matter much what was getting dumped, since they were both scavengers, but for now it was dried fish. Put a steel bearing on the same track and it would pick up even more speed and force, which would trip the lever to a further setting, causing a small bucket of grapes to be lowered for his ravenous lamb. You could stick another bearing into a spring-loaded tube and pull a plunger to send it sailing into a small cart that would get propelled across another track to the other side of the room, where it would trigger a small self-resetting trubuchet that would launch him a piece of whatever was in his fruit bowl. Much to his delight, most of the fruit landed safely in a soft, pillowy basket next to his desk, and only the bananas would get flung full-force at his face, and that was only on account of their awkward shape. There were nearly half a dozen other channels, tubes, grooves and the like that, when loaded with the appropriately weighted sphere, would accomplish similar pointlessly whimsical tasks.

He was proud of Mark IV.

But now that it was done, he should probably get to work on sourcing that copper.

On the other hand, if he could work out the kinks with the pistons—pneumatic or hydraulic, he didn't need to be picky—Mark V might be capable of even more.

Evander's eyes glanced from the rolodex on his desk that contained contact info for all sorts of different metal suppliers and salvage yards to the pad of hastily scrawled plans and blueprints that had led to the contraptions that lined nearly every surface of the front room of his apartment. His hand, with no sense of shame or hesitation, reached for a pen.

Hi i put too much thought into EVERYTHING, This is a long post so beware

[the art is a bit off but i just needed to get this off brain]

App Δ. will be added at a later date

Casing for the Hydraulic Pump located on the shoulder part of the Lifter Class Robotic arm, Which will hence be called: LCR Arm. Casing is made of 1/4 of an inch Tempered steel, Bolts that affix on top of the Iron casing must be 1/2 of an inch at the bottom, and 3/4 of an inch, Bolts must be made of Carbonated Steel.

Hydraulic Pump. The Pump is used to siphon blood and mix with hydraulic compatible/ Troll Blood compatible (Compatible only with Fuchsias and Violets) Oi. 2a. Connectors to the Steel Plaque that holds the Hydraulic pump in place, Connectors are secured with a Grip, Recommendations are that they be soldered on if LCR arm is for Permanent or Semi-permanent Use. 2b. Oil Additive Tube, and Return Tube are located in the same 2 inch thick cylinder which pumps blood with the Added Blood Compative oil into the mechanism to make it's many functions work properly

Support beam located in the 'forearm' section of the LCR arm, It is made with a carbonated steel casing and Iron in the center, Able to support around 1000 kilograms before suffering breakage or bending.

Carbon Muscle fibers, Fibers made with plastic adjacent materials threaded within each other to resemble trollian muscular structure, it is able to contract and relax faster than any normal muscle could attempt without any breakage in the insides of the carbon fibers. 'Elbow' of the LCR arm is must have two 1/2, 3/4 bolts attaching the Support beam [See 3] to the rest of the LCR arm. Bolts must be made of Steel. 4a. Casing for the Arm's Central motor block [See 5] The casing is made of Ferroaluminum, and must be washed at the very least once a week due to the piston's it encases. 4b. Ball Joint Wrist functionality. A Ball joint is located at the "wrist" part of the LCR arm, it is able of 360 degrees of rotation, as well bending forwards and backwards without the assistance of the ball joint. Ball joints are made of Copper with Steel casings, Protecting the ball joints there are two Lock Casings made of Polymer to cushion blows from the Piston Punching Module [see 5a and App. Δ]

Custom Motorblock. A motor block that allows for 4 low action Variable Pistons. The pistons can be exchanged alongside the upper part of the motor block for the variability in the weaker hydraulic powered one or the stronger ignition powered one. [Addendum. 5. Piston Punching Module] As an additive, When the arm's sensors feel the bracing for a punch, Lift or general type of movement that would require force more than precision, it's pistons begin a low-regimen work, after 6 seconds the pistons will begin to move at normal pace and then it will be safe to utilize them. Punching with the module will cause the forearm to extend 4 inches off of the elbow socket, It is held in place by Springs and two Heavy weight bolts so it wiill return to place, This causes the fist to move at a speed higher than the one of the punch, Allowing the "Piston Punching" to occur, This can be used to dig Railway nails to the ground, punching holes through rocks or exposing someone's insides to the outsides [Addendum Finalized] 5a. Variable Pistons. The pistons have a rubber upper socket and must be made by vehicular specificity, The rubber cap is used to cushion blows to the Low Ceiling or the Motorblock. With that in mind it is warned that the motor block cap be changed every Two to three months.

Selection and Application of Liquid Flowmeter

Reading guide: The liquid volume flowmeter consists of a chamber with a known volume and moving parts. The liquid passing through the flow is calculated by determining the volume of the container and the number of movements of the moving parts. According to the characteristics of liquid volume flowmeter, it can be divided into the following types: waist wheel flowmeter, oval gear flowmeter, scraper flowmeter, double rotor flowmeter, reciprocating piston flowmeter, rotary piston flowmeter, screw flowmeter, etc. Structure and principle of the liquid volumetric flowmeter calibration device The liquid accumulation calibration device consists of the quick connector, hydraulic hose, hydraulic filter, standard flowmeter, temperature transformer, pressure transformer, computer system, hydraulic source, etc. The hydraulic oil source also includes a hydraulic oil tank, variable frequency motor, hydraulic variable pump, hydraulic safety valve, and other components. The main features are compact installation, easy use, the same calibration medium, strong movement ability, and the ability to provide hydraulic oil. The working mode of the liquid flow controller is as follows: match through quick connection and replacement, and lead the hydraulic hose into the displaced liquid flow controller calibration device; The hydraulic power converter of the investment department generates clean and stable liquid flow through the hydraulic pump, hydraulic filter, etc. Capture the cumulative flow value determined by the computer system using the calibrated flowmeter and the standard flowmeter, and capture the temperature and pressure on the calibrated flowmeter and the standard flowmeter; The measured value error of calibrated flow is determined by the computer software system. Main characteristics and application of common liquid flowmeter Volumetric flowmeter Volumetric flow meters (also called volume-specific flow values) are general-purpose instruments with the highest accuracy. The measured components can also be divided into the following main features: pitch circle (two rotors), plate flow measurement, oval gear flow measurement, rotary piston flow measurement, circulation flow measurement, etc.

① Advantages: high measurement accuracy; It can be used for measuring high viscosity fluid and simple phase fluid; The instrument does not need external energy to directly record the total flow. It is easy to install without special requirements for front and rear tangent lines. ② Disadvantages: not suitable for high temperature and low temperature; Type of measuring center with limited diameter; Pressure drop; Periodic calibration is required. ③ Application: Volume traffic signs, due to their high-precision measurement in energy, petroleum, medicine, food, chemistry, and other fields, especially raw materials and other fields, must be measured for storage, transfer, and distribution, and used as the basis for a financial settlement, or as a legal indicator of the contract between two tax dealers.

Differential The differential is one of the most commonly used flowmeter types, which can be divided into diverter flowmeter, Venturi flowmeter, average line current, etc. according to the test piece (inlet instrument). The main features are: ① Advantages: single-phase fluid has a wide range of measurement methods, some mixed fluids; Simple structure, easy maintenance, the long service life of control components and detonators, display equipment produced by different manufacturers, improving economies of scale. ② Disadvantages: general customization accuracy; Large pressure loss (orifice plate, nozzle, etc.) The assembly constraint shall be high, and there shall be enough straight pipelines before and after assembly. ③ Nozzle: When measuring the flow in the closed pipe for the first time, the differential can be used for projects under different conditions where the flow is about 1/4-1/3 of the total flow. Ultrasonic assistance The ultrasonic flowmeter can be generally divided into plug-in type, pipe section type, external clamp type, and portable type. ① Advantages: large diameter non-contact measurement, large flow calculation; Pressure loss, no fluid disturbance; Suitable for every liquid, easy to install and maintain. ② Disadvantages: When the measured liquid contains bubbles or noise, the measurement accuracy will be affected; The temperature range of the measured liquid is limited by the heat of the ultrasonic protection and the communication materials between the switch and the line, and the original data for measuring the high temperature of the liquid is incomplete. ③ Application: Ultrasonic velocimeter is often used in petroleum, chemistry, metal, electric power, and other fields, and is often used to measure the emission reduction of gas pipelines in factories, fluids, and work areas.

Turbine speed Intel Remax accelerated technology plan has been expanded to multiple categories in mass production, and its main features are as follows: ① High precision, usually ± 0.25% r - ± 0.5% r, up to ± 0.25% r - ± 0.5% r; Repeat at most 0.05% r-0.2% r for a short time; Zero contact movement, sturdy and durable. ② Disadvantages: The physical characteristics of the liquid have a great influence on the flow characteristics; Calibration characteristics cannot be saved for a long time. ③ Application. A turbine flow counter is usually used to measure oil, organic liquid, inorganic liquid, and liquid frozen body. The first terminal of the main raw material pipeline is used for commercial calculation of automobile exhaust, gas stations, and light hydropower plants.

Vortex flowmeter The vortex flowmeter is the latest flowmeter, but it has developed rapidly and has become a common category. Its main characteristics are as follows. ① Advantages: wide application range, liquid, gas, and steam flow measurement can be used; Small pressure loss; Easy installation, simple and durable structure. ② Disadvantages: poor anti-interference ability; Straight pipe section is required before and after installation; The application experience in pulsating flow and multiphase flow is still lacking. ③ Application: Vortex flowmeter has a wide range of applications, usually used in the factory water supply system, and its application will be limited in the case of high viscosity, low flow rate, and small diameter.

General criteria for flowmeter selection and calibration device Determine the technical requirements for flow measurement and the correctness of the flowmeter, that is, the accuracy requirements for measuring liquid; The flow measurement is repeated, that is, the same measurement is performed multiple times under specific conditions to repeat the same measurement. The expression of flow measurement, that is, whether the flow is mass flow or flow, real-time flow, or cumulative flow. Command and remove the transmission function if necessary. Specifies whether the flow measurement is displayed as a mechanical or electronic title. If the flowmeter does not meet the technical requirements of the measured liquid, measurement errors may also occur.

For the description of the flow calibration liquid calibration device, according to the flow requirements in jgg667-2010: ① The expanded uncertainty of the standard setting should generally not exceed 1/3 of the maximum allowable flow, because the expanded rate of the calibration device is 0.22%.

② Output or. The input line in the equipment used for online identification shall not include redirection between the flowmeter and the equipment designed as a locked cabinet without intermediate circuit. ③ "When the flowmeter is greater than 1.0, the flowmeter and liquid temperature must be measured according to the standard, and the temperature and pressure shall be measured near the standard flowmeter or calibrated flowmeter. Therefore, the liquid flow controller is applicable to the acceptance accuracy standard of Class 1.0 (allowable deviation ± 1.0%) and subsequent fluid calculation.

Conclusion In the process of liquid flow measurement, a liquid flowmeter is a major measuring tool and has been widely used in metallurgy, pharmacy, paper making, water conservancy, environmental protection, petrochemical, and other fields. In the actual online calibration process, the standard volume method, the standard meter method, and the electrical parameter method are all feasible online calibration methods. However, they all have different use conditions, which requires the staff to constantly summarize and analyze the use of online calibration methods for liquid flow meters, so that the calibration methods can be improved.

Universal Testing Machine: Learn About Components & Functions

A universal testing machine (UTM) is utilized to apply tensile, compressive, or transverse stresses to a test piece in order to determine its mechanical characteristics. The machine's name refers to the variety of tests it can run on various types of materials. With the aid of UTM, a variety of tests, including peel, flexural, tension, bend, friction, and spring tests, can be carried out.

Components of Universal Testing Machine

Two primary components make up a universal testing machine as follow:

Loading Unit

Control Unit

Loading Unit

The loading unit controls how the test specimen is set up and how much force is applied. The table and crosshead on the left unit make up the loading unit. Control unit is the right component with a load indicator layout.

The following components make up a UTM's loading unit:

Load Frame

A universal testing device's load frame can be constructed using a single support or two supports. The upper crosshead, lower crosshead, and table that the specimen is set on for the compressive strength test make up the load Frame.

Upper Crosshead and Lower Crosshead

The test specimen is clamped at one end using the top crosshead. The moveable crosshead in the load frame is the lower crosshead, and its screws can be loosened and tightened to change the crosshead's height. A tapered slit runs through the middle of each crosshead. The tensile test specimen is supposed to be held in place by a pair of racking jaws that are located in this slot.

Elongation Scale

The elongation scale that is included with the loading unit measures the relative motion of the upper and bottom tables.

Control Unit

The control unit provides the adjustments in load application and the associated test result. The following are the primary parts of a universal testing machine's control unit:

Hydraulic Power Unit

Load Measuring Unit

Control Devices

Hydraulic Power Unit

This component consists of an oil pump that feeds steady oil into the load unit's main cylinder. The specimen is loaded more easily thanks to this flow. An electric motor and sump operate the oil pump in a hydraulic power unit.

Load Measuring Unit

The pendulum dynamometer in this device travels with the flow of non-pulsating oil in a tiny cylinder. Through a pivot lever, the pendulum is linked to the piston. Depending on the load placed on the sample, the pivot lever will flex.

The load pointer is created from this deflection and shown as the weight on the dial. A knob in the load measuring device allows the user to change the load application range. The measurement unit's precision determines the machine's accuracy rate.

Control Devices

The controls could be hydraulic or electronic. Switches are used by electric control devices to move the crossheads and turn the unit on and off. Two valves—the right control valve and the left control valve or release valve—make up a hydraulic control device. The specimen is subjected to load using a proper control valve.

Functions of UTM

UTM is mostly used to assess the mechanical characteristics of materials. UTM regularly conducts the following tests:

Tensile Test

Adhesion Tests

Bending Test

Hysteresis Test

Compression Test

Pull-Out Tests

Materials that can be tested by UTM:

Concrete

Steel

Winches

Steel Ropes

Cables

Springs

Steel Wires

Slings

Links

Rope

Chains
