Hydraulic fatigue test bench – Automatic 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. Equipment using computer control, by computer control set pressure upper and lower limits, pulse frequency and pulse times, pressure transmitter acquisition system pressure, after the data acquisition card into the computer, computer and pressure transmitter capture static pressure, computer operation control the whole test process, the hose, a variety of metal pipes, non-metallic pipes, joints and accessories and other pressure test, The fatigue life and fatigue failure mode were examined.

Equipment composition

Pulse generator, pressure control gas, pressure sensor, pressure gauge, pressure regulating valve, high pressure valve, liquid tank, electrical control system, testing machine, computer control system, box composition
