Equipment Composition

This test bench consists of three major components as follows:

  1. Hydraulic System: Circulation pump, pulse generator.
  2. Test Cabinet: It is mainly used for mounting test specimens, pressure regulation and system pressure indication.
  3. Electric Control Cabinet & Computer Test System: Start buttons and measuring instruments are all arranged on the console for centralized control and real-time monitoring. The computer system is able to collect parameters including test pressure waveforms, test cycles and pulse frequency. It supports report printing as well as fault alarm notification functions.
