fatigue tester

Usage and Characteristics

The test bench adopts electro-hydraulic servo control technology, suitable for various combinations of shock absorber and cylindrical shock absorber static performance test (dynamometer test, speed characteristics). Test methods to meet the requirements of standards. It uses one pumping station, pumping station is equipped with two sets of 100 liters of Rexroth pump, when demanded small flow, only need to open one pump, when demand for big flow, two oil pumps open at the same time. Two oil pumps can be merged to work, also can be completely independent of supply, do not interfere with each other. In the process of starting and saving the energy plays an important role

The oil tank of the pump station is fully enclosed, which can effectively prevent the external impurities from entering the hydraulic system and contaminating the hydraulic oil.
The oil pump and electric unit are arranged in tandem double – elastic support to further reduce the noise of pump station.
The oil pump adopts the low noise linear conjugate internal meshing gear pump.
The high and low pressure soft switch hydraulic module composed of main overflow valve, accumulator, auxiliary main overflow valve, auxiliary overflow valve and reversing valve and precision filter is used to control the output pressure of the pump station.
