The problem

Static pressure tests cannot screen out winter freeze cracks or water-hammer leaks; the GB/T 19141 80000-cycle pulse test takes a month by hand and the waveform is not recognized. This bench runs the full 8.18 pulse test automatically with recorded waveforms.

Capability

Test peak pressure 0.5-1MPa freely settable, fully automatic control; frequency 1-30 cycles/min (adapted to specimen volume); quasi-trapezoidal waveform with adjustable high/low pressure dwell; pressure sensor accuracy <=0.5%F.S; medium: ambient-temperature water, 700L, auto fill/drain, auto water change above 50C; 600L leak tray with pump for water recycling; air supply 0.5-0.7MPa clean dry air >=1m3/min; PLC + touch screen + industrial PC (ForceControl), waveform and cycle curves recorded and exportable; 24h continuous operation; max liner 500L; approx. 3.2x1.08x1.9m; 380V/50Hz 10kW.
