3. Equipment Composition
This test bench consists of three core components:
Hydraulic System: Circulation pump, pulse generator
Test Cabinet: For mounting test specimens, pressure regulation and system pressure display
Electrical Control Cabinet & Computer Test System: Start buttons and meters are integrated on the console for centralized control and real-time monitoring. The computer system collects parameters including test pressure waveforms, cycle counts and pulse frequency, supports report printing and fault alarm notification functions.
