Working principle of booster pump of grader

Working principle of booster pump of grader: The oil cylinder on grader is driven by air pressure, so that the piston compresses the hydraulic oil downward, thus improving the working pressure of hydraulic pump. During the operation of the hydraulic pump, the hydraulic oil enters the hydraulic pump from the hydraulic oil tank, which is driven by the rotation of the pump wheel in the pump body, compressed and then enters the hydraulic cylinder through the discharge valve. The booster pump of grader is a device to improve the working pressure of hydraulic pump by mechanical means.
