The water pressure test equipment uses compressed air as the power source and the pneumatic hydraulic pump ZTGD400 as the pressure source, outputting water pressure proportional to the driving compressed air pressure. By adjusting the driving air pressure, the corresponding output water pressure can be obtained. When the driving air pressure is balanced with the output water pressure, the pneumatic hydraulic pump stops charging, and the output water pressure stabilizes at the preset pressure.
The system comes with its own water tank (approximately 40L), manual pressure relief valve, and high-pressure pressure reducing valve. It can achieve the functions of pressure relief return water and precise control of output water pressure. Can achieve multi-stage pressure holding and detection testing
