Process design and cleaning method of aluminum castings
Process design of aluminum castings is so subtle that the layman doesn't understand it. Aluminum castings factory Languang can give you a general introduction to the cleaning method of aluminum castings.
Process design of aluminum castings
When the aluminum alloy is smelted, when the heat of formation of the oxides contained in the material in the furnace is lower than that of the aluminum oxide, the aluminum can react with it. As a result of these reactions, the furnace is eroded and the aluminum liquid is polluted. Avoided. In addition, alumina and other oxides in aluminum alloys may also react due to oxides in the materials in the furnace during smelting, but because the smelting temperature of aluminum castings is not high, the reaction is not very obvious.
Among industrial fire-resistant materials, magnesia bricks and fire-resistant clay are both suitable for lining materials for aluminum melting furnaces. Magnesia bricks have low strength under strong temperature changes, and their use is often limited. During the heating process of the aluminum casting, the surface of the aluminum alloy is rapidly oxidized, and with the continuous increase of the temperature, the oxidation rate will also increase. In aluminum alloys, the content of aluminum is very high, so the oxides generated during oxidation are mainly aluminum oxides. In order to reduce the oxidation of aluminum alloys, in addition to the selection of appropriate melting furnaces, in the process of melting aluminum castings, correct operation and technical processes should be adopted. Minimize work.
When casting aluminum castings, attention should be paid to the temperature of the aluminum alloy liquid, neither too high nor too low. at normal casting temperature. The level of casting temperature should be determined according to the application and process of the specific aluminum alloy casting. The general principle is that the processing of aluminum castings is completed under normal circumstances. During the casting process, attention should also be paid to the speed at which the aluminum casting is poured. Generally, it depends on the fluidity of molten aluminum and the level of pouring temperature. Keep the aluminum liquid rising and flowing properly in the casting mold. To get aluminum castings. Of course, in order to smelt aluminum alloys well, it is also necessary to correctly process design of aluminum castings. Make it meet the casting process requirements of aluminum castings.
Cleaning method of aluminum castings
1. Casting cleaning
Generally speaking, the aluminum casting can be further cleaned after cooling. After the aluminum casting is cast in the mold, the cooling time of the casting in the mold is directly related to the material of the aluminum casting and the shape and size of the aluminum casting. Production conditions. Generally, if the cleaning work of aluminum alloy castings is earlier, it will easily cause deformation and cracks in the aluminum alloy castings. The cooling time of castings with large sizes and complicated processes should be longer, and the cooling time of castings with small sizes and thin walls and simple processes can be shorter.
2. Cutting the pouring riser
The main methods of cutting the pouring riser are: gas cutting, grinding wheel cutting, sawing machine, hydraulic cutting, cutting, etc.
3. Surface cleaning of aluminum castings
After the aluminum casting is shelled, there will always be an iron oxide scale remaining on the surface of the casting, which is a casting with complex inner cavities, deep grooves, and blind holes, and cannot be cleaned completely.
4. Shot blasting
Castings can be shot blasted if required. Shot blasting is to use the centrifugal force generated by the rotating shot blasting wheel impeller to throw iron shots on the surface of the castings so that the surface of the aluminum castings has residual sand, sticky sand, or iron oxide scale. Generally speaking, the surface of the casting after shot blasting is related to the size of the iron shot.
5. Repair welding
Usually, it refers to castings that do not meet the technical conditions for acceptance or the ordering agreement and have casting defects but can be repaired. The repaired welding part should be cleaned first so that the surface of the aluminum casting is clean and the metallic luster is exposed. The size of the defect should be welded in order from small to large. For example, the area of repair welding is large and the defect should be annealed after welding in the important part of the casting.
Correctness of casting structure Whether the casting structure is correct or not has a great influence on the quality of the casting, the feasibility and simplicity of the production process, and the production cost. The structure of investment castings should conform to the production characteristics of investment castings. For the quality of investment castings, process ribs and process holes are often set on investment castings as required. Investment casting can cast very complex parts. In order to improve productivity, assemblies and weldments of multiple parts originally produced by other methods can be directly cast into an investment casting after slight structural improvement.
The above is the process design of aluminum castings and the cleaning method of aluminum castings described to you by the aluminum castings factory Languang. If you are interested in this, please contact us!

What problems should the precision stamping hardware factory pay attention to when processing small holes?
With the continuous improvement of the needs of modern life, the precision stamping hardware factory also has different positioning directions for the production of small parts of some products. For example, the processing method of micro holes that was commonly used in the past has been gradually replaced by the metal stamping method. By making the punch firm and stable, the punch strength is improved, the punch is prevented from breaking, and the force state of the blank during punching is changed, etc. . So what are the Processing method of precision hardware?
The ratio d/t of punching diameter to material thickness in the processing of metal stamping parts can reach the following values: 0.4 for hard steel, 0.35 for mild steel and brass, and 0.3 for aluminum.
When punching small holes on the plate, when the thickness of the material is greater than the diameter of the punch, the punching process is not a shearing process, but a process of extruding the material into the die through the punch. At the beginning of extrusion, a part of the punched scrap is compressed and extruded into the surrounding area of the hole, so the thickness of the punched scrap is generally smaller than the thickness of the raw material.
When punching metal stamping parts, the diameter of the punch is very small. When punching holes with ordinary methods, the small punches are easy to break, and what needs to be done is to improve the strength of the punches as much as possible to prevent the punches from breaking and bending. What should be paid attention to when processing small hole metal parts?
The processing method of precision hardware is as follows:
1. The stripping plate doubles as a guide plate.
2. A small guide column guide sleeve is used between the guide plate and the fixed work plate, or it is directly connected with the large guide column guide sleeve.
3. The punch is retracted into the guide plate, and the distance between the guide plate and the punch fixing plate should not be too large.
4. The bilateral gap between the punch and the guide plate is smaller than the unilateral gap between the punch and the concave die.
5. The pressing force should be increased by 1.5 to 2 times compared with the simple stripping.
6. The guide plate is made of or inlaid with high-hardness materials, which is 20% to 30% thicker than usual.
7. The connection line between the two guide posts passes through the pressure center of the workpiece.
8. During multi-hole punching, the punch with a smaller diameter is one material thickness lower than the punch with a larger diameter.
The above is the processing method of precision hardware introduced by precision stamping hardware factory. If you are interested in Processing small hole metal parts, please contact us!

What factors should be paid attention to when manufacturing precision metal parts?
Precision parts processing methods, first of all, need to depend on the technical requirements of the surface of the parts to be processed. It should be noted that these technical requirements are not necessarily the requirements specified on the part drawings, and sometimes may also be due to technological reasons. Aspects are higher than the requirements on the process drawings. What are the precautions for precision parts processing? Precision parts factory Languang summarizes some insights.
For example, the processing requirements of the surface of hardware parts are improved because the benchmarks do not overlap, or they are used as precision benchmarks to put forward higher processing requirements. The required final processing method, and determine the processing method that requires several processes, the selected part processing method should meet the requirements of the quality of the parts, good processing economy, and improved efficiency, so precision parts factory Languang reminds you to choose precision parts processing methods to consider the following factors:
1. The machining accuracy and surface roughness that can be obtained by any kind of precision parts processing method have a relatively large range, but knowledge is economical in some relatively narrow ranges, and the machining accuracy in this range is relatively economical therefore when selecting the processing method, the corresponding processing method that can obtain economical processing accuracy should be selected;
2. It is necessary to consider the material composition of precision hardware parts;
3. The structural shape and size of the hardware parts need to be considered;
4. It is necessary to consider the requirements of production efficiency and economy. In mass production, high-efficiency advanced technology should be adopted, and even the manufacturing method of the blank can be fundamentally changed, which can reduce the amount of movement of precision machining;
5. It is necessary to consider the existing processing equipment and technical conditions of the precision parts factory or workshop. When choosing the processing method, the existing manufacturing equipment should be fully utilized, the potential of the enterprise should be tapped, and the enthusiasm and creativity of the workers should be brought into play, but continuous consideration should also be taken. The improvement of the existing processing methods and equipment, and the use of cutting-edge technology to improve the technological level.
The above are the precautions for precision parts processing and precision parts processing methods summarized by the precision parts factory Languang. If you are interested in these contents, you can contact us to discuss them.

Manufacture and debugging of hydraulic valve block machining
Do you know the process of manufacturing hydraulic valve block machining? Let's take a look at the hydraulic valve block processor Languang.
Manufacture of hydraulic valve block machining
1.
Hydraulic valve block processing each intersecting processing hole
At the intersection of each hole after processing, especially if the metal iron scraps inside the slender hole are not completely cleaned, these iron scraps will enter the system due to the impact of multiple alternating pressure changes during use and cause pollution. Hydraulic valve block processor Languang uses the following methods to control this problem: first, use a small electric or pneumatic grinding wheel to clamp the rotary file, and use a round file for deep holes to clean the flash and burrs at the corners of the channel to achieve smooth and smooth connection; secondly, Use compressed air and high-pressure washing machine to high-pressure wash the dirt on the inner and outer surfaces of the tunnel; thirdly, use industrial, endoscope and cold light sources to check the flash burrs at the corners of the tunnel; after that, demagnetize with high-temperature alkaline water cooking, Use a white silk cloth to clean the residual water and oil in the pores.
2. Hydraulic valve block machining surface
In order to prevent the joint surface of the valve block and the component from leaking, surface roughness and flatness are extremely required. Generally, the roughness of the connecting surface between the component and the valve block should reach Ra0.8, and the connecting surface of the flange, pipe joint, and valve block should reach Ra0.8. The roughness should reach Ra1.6, and the flatness is generally ≤0.01/100mm. Therefore, the surface of the valve block, components, and other connecting surfaces need to be processed by grinding chips. When grinding debris, the magnetic field suction generated by the grinding machine disk makes the ferromagnetic abrasive debris adsorbed on the surface of the valve block or in the hole. This part of the abrasive debris particles is extremely difficult to be washed away, and will gradually disappear from the surface and the surface as the magnetic force is weakened and eliminated during use. The ducts fall off and enter the system, causing serious pollution. For this pollutant, first, demagnetize with a demagnetizer to make the residual magnetism ≤1GS; then use compressed air and a high-pressure washing machine to high-pressure wash the dirt on the outer surface; use high-temperature alkaline water cooking to demagnetize.
Hydraulic valve block processor Languang believes that for the super-long and super-large valve block plane with a length of more than 1000mm, the plane grinding process cannot be performed on the equipment due to the specification limit of the grinding machine so there will be no wear debris adsorbed on the surface of the valve block or in the hole. However, the plane roughness and flatness of the valve block cannot meet the design requirements of the drawing, and the connection surface of the valve, flange, pipe joint, etc. with the valve block will cause oil leakage, and it will also cause pollution. Therefore, an oil stone and a polishing machine should be used for grinding and polishing this kind of valve block, so that the plane can reach more than 100% contact on both sides, so that the surface roughness of the valve block can meet the requirements of connecting valves, flanges, and pipe joints, so as to reduce leakage and reduce Pollution.
3. Anti-rust treatment of hydraulic valve block
The anti-rust treatment on the surface of the valve block is very important. Whether you choose Q235 or 35# or 45#, it must be beautiful and applicable. Poor surface anti-rust treatment will bring pollutants directly into the system when repairing components, causing system pollution and accidents. Hydraulic valve block processor Languang knows there is a way to paint the surface. Direct printing of the valve block surface after assembly of the components. If the components are disassembled, replaced, and repaired by this method, the paint around the components is easily damaged, so the surface of the valve block lacks protection, and the fallen paint and other debris can easily enter the valve block orifice and cause system pollution.
Debugging of hydraulic valve block machining
The debugging of the hydraulic valve block refers to the debugging after the hydraulic valve and hydraulic components are installed on the valve block. The first is to clean the oil circuit, that is, to continuously replace the reversing valve to ensure that all the oil circuits can be cleaned; if there is a servo valve or proportional valve, the flushing cover needs to be replaced. This cleaning is different from the previous block. The cleaning treatment after the processing is completed cannot be omitted.
Debugging of hydraulic valve block machining includes pressure test and function test. During the test, the valve block can be directly connected to the hydraulic system by a Sino-foreign joint venture valve manufacturer, or the valve block test bench can be used alone to test the function of the valve block. The test pressure of the hydraulic valve block shall be determined according to the working pressure of the hydraulic system. When the working pressure is less than 16MPa, the test pressure is 1.5 times the working pressure; the working pressure is 16MPa～25MPa, and the test pressure is 1.25 times the working pressure; for the working pressure of 25MPa～31.5MPa, the test pressure is 1. Working 15 times the pressure.
The above is manufacture of hydraulic valve block machining and debugging of hydraulic valve block machining. If you are interested in the hydraulic valve block, please contact hydraulic valve block processor Languang to read more.

Planning steps and manufacturing requirements of oil block
Do you know what the planning steps of oil block look like? From the appearance, it is a metal block. It is installed in the hydraulic system and is mainly used to control the operation of hydraulic oil. The equipment is classified as a relatively precise part, so When planning, you need to plan well to ensure that every detail conforms to the specifications, otherwise the manufactured products will be useless. Of course, after planning, the manufacturing requirements for oil block also need to follow certain requirements. So do we know what the planning steps of the oil block are? Do you know what are the requirements for manufacturing? The following oil block exporter Languang will tell us about it, let's take a look.
Planning steps of oil block
1. Recognize schematics and components
The main requirement is to separate the connection between the valve and the oil circuit according to the schematic diagram, and to recognize the list of components, distinguish and sort out the list of required components.
2, the establishment of the database
It is required to find out the standard parts from the standard database, and at the same time, it is also necessary to plan and save some non-standard parts used.
3. Three-dimensional view of manufacturing oil block
When making a three-dimensional view of the oil circuit block, it is necessary to determine the position of the bottom plate of each valve device.
4. Oil hole connection
Oil block exporter Languang believes that this process requires that the holes be connected are connected together. When connecting the oil circuit, it is not necessary to calculate the hole depth and coordinates. The planner can plan on the 2D expanded view, and can also clearly see the connection status of the oil circuit through the 3D perspective view and modify it. .
Manufacture requirements for oil block
1. The raw materials (steel plates, forgings) used to manufacture the oil block should meet the relevant requirements in the "General Requirements for Material Acquisition".
2. Mill six sides according to the drawing.
3. Draw lines according to the dimensions of the drawings, and the dimensional tolerances meet the planning requirements.
4. Drilling and adding according to the drawing planning requirements.
5. The oil hole in the oil circuit block needs to be within the range of the entire operating temperature and system flow capacity so that the pressure drop generated by the fluid flowing through the channel will not adversely affect the performance and response of the system.
6. Regarding the oil circuit block with the cover plate type cartridge valve, the socket is processed according to the accuracy required by the drawing. At the same time, pay attention to protecting the appearance of the valve block, and do not bump or scratch it.
7. There should be no scratches or other scars on the surface of the valve block after processing.
8. Check the quality and function according to the construction drawings and the corresponding hydraulic principle.
9. Remove the burrs from all the holes in the valve block.
10. After the treatment is completed, all the holes of the valve block should be cleaned with kerosene, and no impurities such as iron filings should be left.
11. After the valve block is cleaned, block the openings with plastic to prevent dirt from entering, and place them in a clean and dry place together.
12. During transportation, each valve block should be placed in a flexible packaging box alone to avoid bumping and scratching the surface of the valve block.
The above is about planning steps of oil block, if you are interested in the manufacture requirements for oil block, please contact oil block exporter Languang, contact us to read more.

Role of aluminum die castings and repair in life
Aluminum die castings are used to melt aluminum into liquid and inject it into the cavity of the die-casting mold at high pressure and high speed. After the aluminum water is cooled, the mold is opened to obtain a molded product. However, general aluminum die casting uses not scrap aluminum, but aluminum ingots. There are too many impurities in scrap aluminum, which will affect the work of die casting. Aluminum die casting exporter Languang will study with you today.
Role of aluminum die castings in life
1. Due to the stability of aluminum and the ability to not be afraid of water, aluminum die castings will not rust. It is because of this that many decorative products are made of aluminum die castings so that they can remain color-resistant.
2. Since the toughness of aluminum is very good, it determines its plasticity and can be designed into various shapes. Aluminum die casting exporter Languang believes that it is precise because of this that aluminum die castings can be used for recycling, which saves materials and has a wider range of applications. This characteristic of aluminum also determines its creativity, which is very good and can be modified at will.
3. Since aluminum is relatively light, it is more convenient for us to use, and there is no pressure on installation or maintenance.
4. Aluminum die castings have amazing resistance to wind pressure and weathering. At the same time, the weight of aluminum die castings is relatively light, which can reduce the burden on people and reduce the danger.
Repair of aluminum die castings
1. When a die-cast or processed aluminum casting is found to have defects that do not meet the technical requirements, it will generally be scrapped. Aluminum castings with complex shapes, difficult die casting, or long processing cycles. With cast-in inserts, the inserts are made of very precious materials or are difficult to manufacture and cannot be reused after recycling.
2. Light alloys of aluminum castings are widely used in aviation, aerospace, automobile, machinery, and other industries due to their low density, specific ratio, and a series of excellent characteristics. Among them, considering the large quantity, variety, strict requirements, high quality, and a large amount of metal materials, the automobile industry should be promoted.
3. The cost of aluminum castings is good, the craftsmanship is good, and the remelting saves resources and energy, so the application and development of this material are not declining. For example, discuss the cupola-electric furnace double smelting process and equipment; commonly used molten iron desulfurization and filtration technology; thin-walled iron casting manufacturing technology; cast iron composite material manufacturing technology; Technology; using metal mold casting, metal mold sand casting, continuous casting, and other special processes and equipment.
4. In order to reduce fuel consumption and improve source utilization, aluminum die casting exporter Languang believes that it is a long-term development trend to replace steel, iron, and aluminum castings with aluminum and nickel alloy aluminum castings. Among them, refining technology, metamorphism technology, grain refinement technology, and furnace detection technology are emphasized. In order to further improve the performance of the material and maximize its potential of the material, aluminum alloy materials, especially aluminum matrix composite materials, can be used to meet the performance requirements of different working conditions.
The above is the role of aluminum die castings in life introduced by aluminum die casting exporter Languang. If you are interested in the repair of aluminum die castings, please contact us to read more.

Hardware parts processing, Tips for Hardware parts processing
Hardware parts processing and regular maintenance of precision shaft parts processing play a vital role in the service life of the mold. Hardware parts exporter introduces you to some Tips for Hardware parts processing, which can be used by each mold user to ensure the effective operation of mold components such as hot runners, heaters, guide posts, ejectors, forming inserts, etc. to prevent unexpected situations.
Cross-check the resistance value of the heater. You should have measured the resistance of the heater when you first started using it, and it is time to measure and compare it again at the end of the year. If the resistance value fluctuates by ±10%, it is time to consider replacing the heater to ensure it does not fail at a critical point in the production process. If the initial resistance value has never been measured, measure it once and use the resulting value as a reference for future inspections of the heater.
Hardware parts processing, precision shaft parts processing Check for signs of wear between the guide post and guide bush. Look for signs of scratches or scuffs, which are mold-fitting wear due to lack of lubrication. If the marks are just emerging, you can also extend the life of the guide posts and guide bushes by lubricating them. If the wear is severe, it should be replaced with new parts. Otherwise, the cavity and core sections may not fit well, resulting in variable cavity wall thicknesses in the part.
Remember to remind the operator not to "clean" the hot tip at the gate. If the operator happens to see a small piece of stainless steel at the die-fitting nozzle, it may be a point nozzle assembly. "Cleaning up" this seemingly obstructive thing often destroys the hot tip. In order not to damage the hot nozzle, please confirm the nozzle type of the hot runner system before taking action, and ensure that all operators are trained to recognize the different types of nozzles they come into contact with.
The above is the tips for hardware parts processing introduced by hardware parts exporter, Shanghai Languang sells all kinds of Hardware parts, welcome to contact us!

How to know if the hydraulic valve block is good or not
How about the hydraulic valve block
A hydraulic valve is an automatic component operated by pressure oil. It is controlled by the pressure oil of the pressure distribution valve. It is usually used in combination with electromagnetic pressure distribution valves and can be used to remotely control the on-off of oil, gas, and water pipeline systems in hydropower stations. The core component of the hydraulic valve is the hydraulic valve block, which plays an important role in controlling the direction, pressure, and flow of the liquid flow in the hydraulic valve.
The use of hydraulic valve blocks can not only simplify the design and installation of the hydraulic system but also facilitate the integration and standardization of the hydraulic system, which is conducive to reducing manufacturing costs and improving accuracy and reliability.
Production of the hydraulic valve block
1. The surface roughness of the valve and flange installed on the hydraulic valve block should reach Ra0.4, and the surface roughness of the sealing surface of the end pipe joint should reach Ra3.2. In addition, the verticality tolerance between the screw hole for installing the pipe joint and its outer abutment surface should be at least grade 8.
2. All screw holes on the valve block should have machining accuracy requirements. Generally, 7H is selected. The machining accuracy of the mounting holes of the threaded cartridge valve should comply with the requirements of the product samples. The roughness of the mounting holes of the cartridge valve is Ra0.8. In addition, there are also requirements for dimensional tolerances and geometric tolerances. The surface roughness of the O-ring groove is Ra3.2, and the surface roughness of the general runner is Ra12.5.
3. The high-pressure valve block is made of 35 forged steel, and the general valve block is made of A3 steel or ductile iron. When cutting the valve block material from the plate with gas cutting, there should be enough machining allowance, and the blank of the valve block should be forged. Reprocessing. The material of the processing valve block must ensure that the internal structure is dense, and there should be no defects such as interlayer and trachoma. If necessary, the blank should be inspected. Cast iron blocks and larger steel blocks should be aged and pretreated before machining.
Precautions for hydraulic valve block design
1. In the design of the hydraulic valve block, the oil circuit should be as simple as possible, and the deep holes, inclined holes, and process holes should be minimized. The hole diameter of the valve block should match the flow rate. In particular, it should be noted that the intersecting holes must have sufficient flow area. Pay attention to the direction and position of the oil inlet and outlet, which should match the overall arrangement of the system and the form of pipeline connection, and consider The manufacturability of the installation operation, components with vertical or horizontal installation requirements, must be guaranteed to meet the requirements after installation.
2. For the components that need to be adjusted in the work, the convenience of operation and observation should be considered in the design. For example, the adjustable components such as the relief valve and speed control valve should be set in a position where the adjustment handle is easy to operate.
3. Components and key components that need to be inspected frequently, such as proportional valves, servo valves, etc., should be located above or outside the valve block to facilitate disassembly and assembly. In addition, a sufficient number of pressure measuring points should be set up in the valve block design for valve block debugging. For valve blocks weighing more than 30kg, lifting screw holes should be provided, but under the premise of meeting the requirements of use, the volume of the valve block should be as small as possible.

The design of CNC turning machine parts should focus on the following 3 points:
1. Runner, gate balance
Shrinkage varies with resin pressure. In the case of single-cavity molds with multi-point gates and multi-cavity molds, gate balancing is required to perform the same mold filling. The resin flow is related to the flow resistance in the runner, so take the runner balance before taking the gate balance.
2. Cavity arrangement
In order to make the setting of molding conditions easy, it is necessary to pay attention to the arrangement of the cavities. Since the molten resin heats the mold, in the case of a general cavity arrangement, the mold temperature distribution is concentric with the gate as the center. Therefore, when choosing the arrangement of the cavities of the multi-cavity mold, it is not only easy to balance the runners, but also to take the concentric arrangement with the gate as the center, so that it is easier to make CNC components.
3. Cooling circuit design for precision injection molding
The temperature of the mold has a great influence on the shrinkage rate. At the same time, due to the temperature change at different times, the temperature difference of each cavity of the multi-cavity mold is unavoidable, so it is necessary to pay attention to the design of the cooling circuit. In the circuit design, the heat that should be carried out by the cavity and the core is also different, and the thermal resistance is also different due to the different circuit structures, and the inlet water temperature has a large difference between the cavity and the core. Therefore, the cooling circuit of the precision forming mold is designed separately for the cavity and the core, and the temperature is controlled by a separate temperature controller.
As CNC component supplier, Shanghai Languang Precision Machinery Co., Ltd. sells CNC turning machine parts, CNC parts and hydraulic CNC lathe accessories, and is also a professional manufacturer of CNC components.

Introduction to Optical Sensors
The types of optical sensors mainly include laser, infrared light, illuminance, visible light, image sensors, etc., which utilize some inherent characteristics of light and are rapidly developed sensing technologies. For example, the emergence of laser has made radio technology and optical technology advance by leaps and bounds, penetrating and complementing each other. Now, many sensors have been made by using laser, which solved many technical problems that could not be solved before, making it suitable for dangerous and flammable places such as coal mines, oil, and natural gas storage. There are also optical fiber sensors made of lasers, which can measure the parameters of crude oil injection and cracking of oil tanks. In the actual measurement site, there is no need for a power supply, which is especially suitable for petrochemical equipment groups that require strict safety and explosion-proof measures and can also be used to implement optical telemetry chemical technology in certain links in large steel plants.
The principle of the magneto-optical effect sensor is to use the polarization state of light to realize the function of the sensor. When a beam of polarized light passes through a medium, if there is an external magnetic field in the direction of beam propagation, the light will rotate at an angle through the plane of polarization, which is the magneto-optical effect. That is, the applied magnetic field can be measured by the angle of rotation. Under a specific test device, the deflection angle is proportional to the output light intensity. By irradiating the laser diode LD with the output light, digital light intensity can be obtained, which can be used to measure specific physical quantities.
Ambient light sensors have been widely used in consumer electronics products this year. They can be used to sense ambient light conditions and tell the processing chip to automatically adjust the brightness of the display backlight to reduce the power consumption of the product. For example, in mobile applications such as mobile phones and notebooks, the display consumes up to 30% of the total battery power, and the use of ambient light sensors can maximize the operating time of the battery. On the other hand, the ambient light sensor helps the display deliver a soft picture. When the ambient brightness is high, the LCD monitor using the ambient light sensor will automatically adjust to high brightness. When the external environment is dark, the display will be adjusted to low brightness to automatically adjust the brightness.
Optical sensors are very common in our lives. The image sensor in the early camera is a kind of optical sensor, but many people do not pay more attention. In fact, many sensors are all around us.
