The system adopts motor-fan pressurization as the main power source, and the test process is controlled through computer + PLC control with data acquisition. The equipment is designed as a comprehensive testing platform for petroleum tank accessories, integrating different test functions into one system.
For breather valves and hydraulic safety valves, the system can perform opening pressure, ventilation volume, and leakage related tests. For flame arresters, it can perform ventilation volume–pressure loss testing. The technical proposal also states that the system can perform non-standard ultra-high-pressure tests within ±50 kPa for breather valve opening pressure and leakage.
