The fatigue test bench designed by our company is a high-performance test bench developed by absorbing advanced foreign experience and combining with the actual needs of domestic corresponding industries. The main components of the equipment adopt imported pneumatic components-electrical proportional valves or imported servo valve components, combined with the measurement and control software of the American NI company, making the entire equipment simple to operate and stable in performance, and can perform various pressure fatigue tests.
Scope of application:
Car steering pipe, brake pipe, air conditioning pipe, fuel pipe, cooling water pipe, cooling hose, heating hose, air filter hose, worm gear, booster system hose, engineering hydraulic hose, aviation hose and manifold , Rigid pipes or joints, heat exchangers, air conditioners, filters, etc.

The main technical parameters:
Maximum fatigue pressure: 100MPa, pressure display accurate to 0.1MPa
Fatigue frequency: 0-0.5HZ
Test medium: hydraulic oil or water medium temperature: ambient temperature -150 + 3 ℃
Number of cycles:> 100,000
Main functions and features:
◎ It is composed of computer and American NI acquisition card (LABVIEW software) control system. It adopts electro-hydraulic servo control. The fatigue pressure can be adjusted within the adjustment range arbitrarily, and the control is precise and high.
◎ Multi-channel and multi-station, can carry out multi-channel test at the same time without affecting each other. When the tested workpiece is blasted during the pulse test, it will not affect other workpieces to continue testing. Computer.
◎ The computer is used for data collection, control and management. Fatigue pressure, ambient temperature, medium temperature, number of tests, waveforms can be set through the human-machine world, and can be printed out.
◎ Adopt accumulator pressure to improve the reliability, stability and service life of the pressurization system, while ensuring pressure accuracy.
◎ Automatically exclude the gas in the sample at the beginning of the test (for the hose test), reach the test fatigue times, stop automatically, and have the automatic recovery function of the leaked medium after dismantling the workpiece to be tested.
◎ The inner layer of the observation window is a protective net and the outer layer is plexiglass to ensure maximum personal safety. Built-in lighting makes it easy to install and disassemble the workpiece and observe the internal test conditions when the light is poor.
◎ Hydraulic oil cooling method uses self-circulating cooling of the hydraulic oil in the oil tank and water cooler cooling. The effective volume of the oil tank is 10 times the flow rate of the oil pump at the pumping station, so it has good heat dissipation. A water-cooled radiator is installed to dissipate the fuel tank.
◎ It consists of two parts: control cabinet and test case. Equipment layout is reasonable, water and electricity are separated, all pipelines are connected by stainless steel pipes.
◎ Different tooling fixtures are suitable for the connection of hoses and hose assemblies;
◎ It can take flexural fatigue test and no flexural fatigue test. * (Optional)
