ENERGY-SAVING GAS-LIQUID BOOSTER CONTROL DEVICE

WIPO Patent Application WO/2020/177611

A1

Disclosed is an energy-saving gas-liquid booster control device. By means of an air cylinder driving two oil cylinders to act in a staggered manner, oil suction and oil discharge are performed at the same time, thereby avoiding the defect of oil supply interruption of a traditional booster device while improving the efficiency, and realizing gas-liquid boosting. The invention further comprises a pneumatic pressure regulating valve and a hydraulic accumulator, oil discharge pressure of a hydraulic system constituted by the oil cylinders is controlled by means of a pneumatic pressure valve regulating air intake pressure, and the hydraulic pressure accumulator buffers pressure fluctuation, caused by intermittent oil supply generated at the moment of reversing of the air cylinder, of a gas-liquid booster control device. Moving components, such as a piston, of the device use a large quantity of aluminum alloy, thereby reducing the weight of a reciprocating moving component as much as possible while ensuring strength, improving the sensitivity of reversing, and also reducing pressure fluctuation while reducing energy consumption in reversing.
