Hydraulic Hose Pressure Impulse Fatigue Test Bench

Pulsating pressure test bench that cycles hydraulic hoses and assemblies between set pressures at high temperature until failure. Used by hose manufacturers and automotive brake and power steering line suppliers.

Specification

Hose assemblies are filled with hydraulic oil and subjected to repeated pressure impulses with a programmable waveform and oil temperature up to 120 deg C. A cycle counter stops each station on leakage, so cycle life can be compared across hose constructions and fitting designs.

Features

• Four independent hose stations with leak detection cut-off
• Programmable waveform with adjustable rise rate and dwell
• Heated oil circuit with PID temperature control
• Burst pressure test function up to maximum rated pressure
• Safety shield and pressure relief valve on every station
