Several factors that affect the service life of UHP hoses

Several factors that affect the service life of UHP hoses:
First, the path matching in the EHV hose is to be selected according to the requirements of the host of the ultra-high pressure washer. Because the pressure and flow of the ultra-high pressure washer have very strict regulations or restrictions, the change in the diameter of the pipe will affect the high-pressure water The working force of the front of the jet and the balance of the system. Experiments have shown that the diameter of 4mm ultra-high pressure hose instead of the specified diameter of 5mm ultra-high pressure hose, the service life is reduced to the original one-third.
In addition to this, there are metal hoses and hoses used for the use, storage and storage requirements, which refers to the matters that need attention when it comes to disassembly.
Second, the pressure matching and selection of ultra-high pressure hose, according to the operating pressure of the ultra-high pressure washer, based on the correct selection of the appropriate pressure level hose. When the actual use of pressure exceeds 1.25 times the specified pressure, the hose The working life will be reduced by 50%.
In addition, the impact on the service life of extra-high pressure hoses is very large, including the pressure fluctuations of the super-pressure washer in the working process, the high-pressure spray gun, the momentary opening and closing of the control valve, and the fluid pressure fluctuation in the tube. Therefore, it is recommended that When selecting an extra-high pressure hose, it should be selected according to 1.5 times the working pressure. For example: The working pressure of the ultra-high pressure washer is 1200 bar, and an ultra-high pressure hose with a working pressure of 1800-2000 bar should be selected. Extend the service life of ultra-high pressure hoses.
The technical level of the metal hose and the hose hose in the production process, the quality of the inner layer and the joint, the correct selection and use of the hose and many other factors, have a great service life for the metal hose and the hose hose. The following are the main factors affecting the service life of the ultra-hose.
