Product Description

| Product introduction

Air-air booster pumps are based on the principle of force balance. A very low pressure is applied to the large diameter air-driven piston, and the resulting force is transmitted to the piston in a small area through the piston rod, pushing the small piston to move in a confined space, and a high pressure is generated by gas compression. With a pneumatically controlled valve, the booster enables continuous operation. The directional valve alternates the actuating gas on both sides of the large piston. The high-pressure piston controlled by the check valve continuously discharges the gas, and the pressure of the booster pump is related to the driving air pressure (while the booster efficiency of the pump is directly related to the inlet pressure of the pressurized gas, that is, the higher the inlet pressure, the more gas is transported in a single stroke). The final output pressure of the booster pump can be calculated according to the formula in the table of technical characteristics of the booster pump. When the pressure between the drive section and the booster part of the gas reaches equilibrium (that is, when the force acting on the drive piston and the booster piston is equal), the booster pump stops running and no longer consumes air. When the output pressure drops or the air drive pressure increases, the booster pump automatically starts operation until the pressure equilibrium is reached again. In addition, the gas-pneumatic booster pump can be switched on and off automatically via pneumatic switches or external controls. Gas booster pumps are divided into air booster pumps and other gas booster pumps. The air booster pump pressurization medium is compressed air. The medium of other gas booster pumps can be compressed air, nitrogen, helium, argon, etc.

| Product application

YQQBD series gas booster pump is a single-drive head single-stage double-acting pump. In order to achieve the required pressure, the air pressure input at the gas inlet requires a certain degree of pre-increase, which varies depending on the maximum pressure achieved, and can be increased up to 1200 bar. The maximum driving air pressure is 1MPa, and the pump heads at both ends are cooled with exhaust gas.
