[0002] A gas-driven liquid booster pump is a device that uses gas to boost the pressure of liquid. It usually consists of a gas drive device, a liquid booster device, and a control system. The working principle of a gas-driven liquid booster pump is that the gas pressure provided by the gas drive device (such as a cylinder) acts on the liquid to achieve the pressurization of the liquid. When the gas pressure acts on the liquid, the liquid will be pushed and gradually pressurized, and finally output to the required location.
