Hydraulic fatigue test bench – manual control mode

Equipment introduction

The fatigue test bench simulates the bearing parts in the actual working condition to carry out pressure alternating pulse test on the bearing parts to check whether it can complete the number of cycles specified in the standard, check its fatigue life and fatigue failure form. The equipment adopts manual control, the upper and lower limits of pressure, fatigue frequency and fatigue frequency are set by the instrument, the pressure transmitter collects the pressure of the system, the hose, various metal pipes, non-metallic pipes, joints and accessories and so on pressure test, check its fatigue life and fatigue failure form.

Equipment composition

Pulse generator, pressure control gas, pressure sensor, pressure gauge, pressure regulating valve, high pressure valve, liquid tank, electrical control system, test case
