It is composed of computer and control system of American NI acquisition card (LABVIEW software). The electro-hydraulic servo control system can adjust the pulse pressure arbitrarily in the range of regulation, and the control accuracy is high.
Multi-channel multi-station, can simultaneously carry out multi-channel tests without affecting each other. When the measured workpiece is blasted in the pulse test process, it does not affect other workpieces to continue testing. It realizes unattended, experimental data and graphics are automatically recorded and saved in the computer.
Data acquisition, control and management by computer. Pulse pressure, ambient temperature, medium temperature, number of tests, waveform, can be set by the human-machine world, and can be printed out.
The accumulator is used to compensate the pressure, which improves the reliability, stability and service life of the pressure system and ensures the pressure accuracy.
At the beginning of the test, the gas in the sample can be automatically eliminated (for the rubber tube test), the number of test pulses can be reached, the machine can stop automatically, and the leakage medium can be automatically recovered after disassembling the measured workpiece.
The inner layer of observation window is protective net, the outer layer is plexiglass, which ensures maximum personal safety. Built in lighting, easy to disassemble the workpiece and observe the internal test condition when the light is poor.
Hydraulic oil cooling mode adopts hydraulic oil self-circulating cooling and water cooler in the tank. The effective volume of the tank is 10 times of the flow rate of the pump in the pumping station, so it has good heat dissipation. In order to make the motor and pump set work for a long time, water-cooled radiator is installed on the outside side of the tank to heat the tank.
It consists of two parts: the control cabinet and the test box. The equipment layout is reasonable, the water and electricity are separated, and all pipelines are connected by stainless steel pipes.
Different fixtures are suitable for connection of hose and hose assembly.
Flexural pulse test and non flexural pulse test.
