Working principle

Pressure gauge check table adopts gas-liquid supercharger as pressure source: It uses compressed air as power source, and the output liquid pressure is proportional to the driving air pressure. By adjusting the pressure of driving air source, the corresponding liquid pressure can be obtained. According to the different pressure of the specimen, the driving gas pressure is adjusted. The high-pressure liquid generated by the gas-liquid supercharger is transported to the specimen by the high-pressure pipeline through the pressure control system for pressure proofreading. Precision pressure regulating valve is used to control the compressed air source, and the air source controls the output pressure of the supercharger.
