Liugong hydraulic valve durability test bench built to fill the gap in the domestic industry

Liugong Co., Ltd. hydraulic valve durability test bench was recently built and put into operation. The hydraulic valve durability test is an important part of the hydraulic valve test. At present, some benchmarking companies in the world have certain applications. The successful operation of the test bench in the valve industry is a domestic initiative, filling the gap in the domestic industry. The use of a hydraulic valve durability test bench has played a crucial role in improving the durability of the hydraulic valve. Hydraulic valves will withstand large alternating pressure shocks during actual operation, which will cause hydraulic valves to be subject to fatigue damage under the influence of alternating pressure. Through the hydraulic valve durability test bench in the laboratory simulation of hydraulic valve withstand long-term alternating pressure actual conditions, can expose the hydraulic valve in the alternating pressure possible quality problems, easy to find out the weakness of the hydraulic valve durability, improve Design and mass production increase valve durability.

At present, the test rig has completed commutative connection P, LS and A, B port high pressure test, and is undergoing the test of the inlet and outlet oil linkage valve body. The valve stem, compensation valve and end cap durability test will be performed soon. (This article is from Liugong)
