High Frequency Pulse Pressure Test Bench Hydraulic Pulse Cycle Test Equipment Pipe Fitting Pressure Pulse Fatigue Tester
Product Description:
The pulse test bench, also known as the fatigue test bench or pressure alternating test bench, simulates the actual working conditions of pressure-bearing components (including the medium flowing through the pressure pipe and the pulse pressure they are subjected to). It conducts pressure alternating pulse tests on the pressure-bearing components to assess whether they can complete the number of cycles specified in the standard under high and low pressure conditions, and to evaluate their fatigue life and fatigue failure mode.
Applications:
This instrument is suitable for various hoses, automotive hoses, hydraulic hose assemblies, metal pipelines, oil pipelines, automotive steering hoses, brake hoses, air conditioning hoses, fuel hoses, coolant hoses, radiators, heater hoses, hydraulic equipment, condensers, evaporators, air conditioning filter hoses, turbocharger system hoses, automotive brake pumps, cylinder blocks, engineering hydraulic hoses, aviation hoses and manifolds, rigid pipes, fittings, valves, pressure gauges, pressure vessels, pressure transmitters, etc.
