Although the service life of hydraulic oil pipe is relatively long, the non-standard use will also affect the service time. What are the factors affecting the service life of hydraulic oil pipe?
1、 Pressure matching
When using and selecting super hydraulic oil pipe, it shall be based on the working pressure. If the pressure used exceeds 1.25 times the specified pressure, the service life of hydraulic oil pipe will be reduced by 50%.
What has a great impact on the service life of the hydraulic oil pipe is the pressure fluctuation of the ultra-high pressure cleaning machine in the working process. When opening and closing, it will cause the fluctuation of fluid pressure and increase the pressure. Therefore, when purchasing the hydraulic oil pipe, it should be selected according to 1.5 times of the actual working intensity, which can greatly prolong its service time.
2、 Path matching
When the hydraulic oil pipe is equipped, it shall be selected according to the requirements of the host of the ultra-high pressure cleaning machine. The change of the diameter in the pipe makes the working strike force and the system unbalanced. The experiment shows that replacing the hydraulic oil pipe with the specified diameter of 5mm with the hydraulic oil pipe with the diameter of 4mm will reduce the service life by 3 / 1.
3、 Avoid bending.
(1) When the ultra-high pressure cleaning machine is in working state, the hydraulic oil pipe shall avoid bending as much as possible. If it is necessary to bend, ensure that the bending radius of the hydraulic oil pipe is not too small, otherwise the inner steel wire will be compressed, affecting the service life of the hydraulic oil pipe.
