Camlock coupling is widely used in tanker

According to the current method of filling the tank, after tank filling and before they unload tube. Whether after gas and liquid pipes are closed to take over the ball on the filling hose Y-valves and tanker terminals directly discharged rapidly LPG joint segment, and then remove the camlock coupling of this approach, in order for the tanker industry, LPG wholesale business, there are two issues worth considering: first, the emissions of LPG  improve job site concentration of the gas, so that the local area within a certain time LPG gas concentration reaches its explosive limit despite the explosion sites, but from a security point of view, after all, is a safety hazard, to be eliminated. Second, from the perspective of economic value, drained of LPG is a reasonable wear and tear, or waste?

Select the camlock coupling according to the usage environment

First pay attention to the shape and size of the installation when select camlockcoupling , determine the model and material of the quick connector, and specify the assembly shape and size corresponding to the piping characteristics. Please note that the dimensions are related to fluid flow. The use environment of the camlock coupling, including the camlock coupling of the structure and material suitable for the environment to be used: Consider the humidity conditions of the use environment, the condition of the dust, and the environment in which corrosion is easy, and consider the type of the quick connector and the body material. Sealing material. Precautions for use of camlock coupling: Do not exceed the maximum operating pressure limit when using it. Please do not use it for fluids other than fluids. The fluid must be clean fluid filtered through the filter. Do not remove the camlock coupling, do not use the hose with cracks. Prevent leakage or falling off. For equipment with vibration and impact, the durability will be reduced. Do not artificially hit, bend, stretch or prevent damage. Do not use it outside the operating temperature range to prevent the sealing material from being worn. Or leak, do not use it in places such as metal powder or sand dust to prevent malfunction or leakage. For thread type installation, do not exceed the maximum tightening torque during installation to prevent damage.

Brief introduction of polishing performance of stainless steel camlock coupling

Stainless steel camlock coupling are believed to be familiar to everyone. Now we introduce several methods for washing it. Because it has been in the air for a long time, it is inevitable that there will be dust or dirt. At this time we can wash with soap or warm water. If it is a trademark on the surface, we use a weak lotion and warm water to rinse. If it is contaminated on the surface, we should use a soft cloth to clean it and then wash it with a special detergent. Sometimes we see a rainbow pattern on the surface, which is caused by excessive use of detergent or oil. We can use warm water detergent. As long as we choose the right cleaning method and maintenance method, we can greatly extend its life. No matter what stainless steel products need everyone’s maintenance and maintenance, it can be used longer. The copper sulfate point test is the easiest way to quickly distinguish between ordinary carbon steel and all types of stainless steel. The concentration of the copper sulfate solution used is 6 to 10%. In the test area, the grease or various impurities should be thoroughly removed in the test area, and a small area should be polished with a soft cloth, and then the copper sulfate solution should be dripped into the cleaned area with a drop bottle. Ordinary carbon steel or iron forms a layer of surface metallic copper in a few seconds, while stainless steel surfaces do not produce copper deposits or show copper color.

What are the reasons when camlock coupling occurs fault in use process of device

Camlock coupling hydraulic system abnormal pressure normal fragmented tube set aside a lot of pressure,measuring points, the use of pressure gauges to measure the reading, compared with the deformity can be integrated to determine the pressure caused by the pressure of the same hydraulic components. Schedule abnormal adjustment diet valve, price control valve and variable pump variable organization, the implementation of the components should be tested for the progress of the scope of value, compared with the expected value can be sure. Different measures to switch each valve to inspect the implementation of the components of the form of action can be deformity, you can find the same reversing valve, the review measures measures to grasp the first and process to find strange place. The other emerging strange vibration, music, oil spill, fever, etc., no need to be busy turning off the lights, should be touched and see three inspections, certainly strange and comprehensive solution. Analyze the mechanics of hydraulic flow used in hydraulic joints, and in practice the hydraulic joints cease to be comprehensive for any problems with hydraulic circuits and hydraulic components. Example to indicate the normal search process hydraulic connector problems. Problems: hydraulic pump cavitation; problems Scene: vibration, music, cavitation; The secondary reason: pump suction port pressure lower than the gas pressure, or inhalation atmosphere. Determine the synthesis: the application of energy equations and flow continuity equation for the hydraulic pump suction process to stop synthesis, can determine the hydraulic connector hydraulic pump problems: the tank surface pressure is too low – Light speed too high.

How to avoid camlock coupling buckling deformation

In China, the automobile manufacturing industry, home appliance manufacturing enterprises, or maintenance of self-employed, are heavily used compressed air as a power source, therefore, will use the camlock coupling.

When welding a thin plate member, the residual compressive stress in the area away from the weld zone causes the plate to be buckled and deformed to determine whether the deformation is caused by buckling stress or bending.

The reason for the buckling deformation of the camlock coupling is not only different from the bending deformation, but also the shape and size of the performance are not the same, the difference is: the rapid joint buckling deformation of the value is generally much larger than the bending deformation; camlock coupling buckling deformation Stable state more than one, in the same specimen along the weld centerline may appear in a variety of different forms of stability.

The quick link buckling deformation is related to plate width, plate length, welding line energy and welding residual stress. When the ratio of plate width to plate length is constant, the critical thickness does not increase with the increase of plate width. In the case of constant plate width, the critical thickness increases with the increase of the aspect ratio The With the increase in welding line energy, not only the beginning of the deformation of the weldment before the time, but also to the final deformation of the welds increased.

Since the buckling deformation of the camlock coupling is caused by the residual compressive stress, in order to avoid buckling deformation, it is necessary to make the welding residual stress value lower than a critical stress, which can be reduced by reducing the welding amount and reducing the welding line energy Residual stress of welded components. Under the possible conditions of the use of intermittent welding, welding can be reduced by half, so that the residual stress is greatly reduced. Another way is to reduce the size of the weld, but also to achieve the same purpose.

What are the areas where camlock coupling are widely used?

The rapid application of the camlock coupling is almost wide to people no longer count clear, maybe he looks so much small, so insignificant,but in fact its function is very powerful, he through their own connection, will need to connect the two objects to be well connected, and then play its role. I think that’s all we know. All about the camlock coupling of the rapid articulation of the explanation, of course, in so many areas, we have not really used such an instrument,but in life it is also used to see, such as the car inside the battery and the connection between the car is achieved by camlock coupling. So in the end want to say is that we may be able to ignore such a camlock coupling, but still can not ignore its role in the end.

Camlock coupling used in cooling water, warm oil

Mainly used for general-purpose mold interface. The realization of the mold to achieve the simplification of the operation, to Strengthen the anti-rust function and types are various. Precautions for use: Please do not use fluid with cooling water, quick oil with camlock coupling. Do not use the maximum operating pressure limit. Do not use outside the use temperature range, to prevent the sealing material wear or leakage. Do not carry out artificial hitting, bending, stretching, to prevent damage caused. Do not mix with metal powder or sand dust and other places to prevent the work caused by poor or leakage. The installation of the thread is not to exceed the maximum tightening torque during installation to prevent damage. Do not use hoses with cracks to prevent leakage or loss. Such as for vibration, the impact of the machine will cause reduced durability. The fluid must be a clean fluid filtered through a filter. Do not disassemble the camlock coupling.

Details needs attention when use stainless steel camlock coupling

Stainless steel camlock coupling is made of iron chrome alloy and then mixed with some other trace elements, if the use of defective, the trace metal elements will gradually accumulate in the human body, when reaching a limit, it will threaten the human well. Consumers use stainless steel camlock coupling kitchen utensils, tableware must pay attention to the following four points. One, not a long time in full bloom salt, soy sauce, hot soup and so on. These foods contain a lot of electrolyte, long time in full bloom, stainless steel camlock coupling will be like other metals, with these electrolytes attack electrochemical reaction, so that harmful metal elements precipitation. Second, do not hold a long time strong acid foods (such as melons, fruits, vegetables, soybeans, potato), to prevent chromium, nickel and other metal elements dissolution. Third, do not use stainless steel camlock coupling utensils suffering from traditional Chinese medicine. As the traditional Chinese medicine contains a lot of alkaloids, organic acids and other ingredients, especially in the premise of heating, it is difficult to prevent non-attack with the chemical reaction, leaving the drug ineffective, and even produce some of the more toxic compounds. Fourth, do not use strong alkaline or strong oxidizing chemicals such as soda powder, bleaching powder and other washing stainless steel camlock coupling tableware. Because these substances are electrolytes, they react with stainless steel camlock coupling for chemical reactions, and then occur harmful to the human body.
