HMC-20Automotive pipeline pulse test bench

Product Name:Automotive pipeline pulse test bench

Product Model 2:HMC-20

Three main purposes and functions

   Automotive pipeline pulse test benchThe test is suitable for measuring the pulse, vibration, and expansion of automotive hoses, assessing their fatigue life and fatigue failure modes. The automatic identification and corresponding handling of sample failure or machine malfunction are controlled by computers to enable various subsystems to achieve the testing process and protection functions. The pulse and vibration test section breaks the traditional method of using hydraulic cylinders and servo valves to control the test bench. And in the form of an electric cylinder, this form does not require hydraulic oil or an oil tank. It has the advantages of saving space, protecting the environment, high work efficiency, and easy maintenance.

productFunction:
1. Computer data acquisition and processing, printing and outputting media temperature, pulse frequency, vibration frequency, and pulse pressure waveform;
2. Experimental waveforms: triangular wave, sawtooth wave, trapezoidal wave, sine wave, etc. The control methods can be displacement control and load control.
3. The inner and outer wall panels and glass windows of the test chamber have explosion-proof and anti scalding functions, which are convenient for operation and observation;
4. Safe and reliable grounding protection;
5. Power phase loss, undervoltage, overvoltage, phase sequence protection;
6. Fan motor overcurrent protection;
7. Refrigeration machine overpressure and overload protection;
8. Heater short circuit protection;
9. The electronic control system has protective devices (partially) that can automatically shut down the entire machine and sound an alarm when starting.
