The high-pressure wing union is an important part of the ultra-high pressure cleaner. It is an important original for connecting nozzles and ultra-high pressure pumps. In the operation of the ultra-high pressure cleaner, there are many factors affecting the life of the high-pressure wing union. In addition to the process level of the hose in the manufacturing process, the quality function of the inner layer and the joint, the correct selection of the high-pressure wing union The use of many other factors has a great influence on the life of the wing union. The following are the three main elements that affect the high-pressure wing union:
First, the pressure match
When using and selecting the high-pressure wing union, the hose of the appropriate pressure rating should be correctly selected based on the operating pressure of the ultra-high pressure cleaner. When the actual applied pressure exceeds 1.25 times the regular pressure, the operating life of the hose will drop by 50%.
In addition, the impact on the life of the high-pressure wing union is very large, as well as the pressure fluctuation of the ultra-high pressure cleaner during the operation, the opening and closing of the high-pressure spray gun and the control valve to form the fluid pressure fluctuation in the tube. Therefore, it is recommended that when purchasing the high-pressure wing union, it should be selected according to 1.5 times the working pressure. For example, the working pressure of the ultra-high pressure cleaner is 1200 bar, and the high-pressure wing union with the working pressure of 1800-2000 bar should be selected. This can greatly extend the life of the high-pressure wing union.
Second, the path matching
When equipped with high-pressure wing union, it should be selected according to the requirements of the ultra-high pressure cleaner mainframe. Because the pressure and flow of the ultra-high pressure cleaner have very strict rules or constraints, the change of the inner diameter of the pipe will affect the front end of the high-pressure water jet. Strike and system balance. Tests have shown that the diameter of the 4mm high-pressure wing union instead of the regular diameter is 5mm high-pressure wing union, the life of the application is reduced to the original one third.
Third, high-pressure wing union on the use, storage and preservation
