A plunger pump has two check valves with opposite directions

For pumps that run at Submersible Drainage Pumps Manufacturers speeds or transmit large energy, check regularly and record the amplitude, frequency and noise of each component. 5 (6) The output flow of the hydraulic pump is insufficient or the oil does not output 1. If the cylinder body of the hydraulic pump and the valve plate have a large amount of leakage, and the cylinder body may be broken in severe cases, the mating surface should be reground or the hydraulic pump should be replaced. The displacement of the pump is small, which requires adjusting the variable piston to increase the tilt angle of the swash plate.

When the chute (stop supply side) on the plunger communicates with the oil return hole on the sleeve, the low pressure oil passage of the pump oil chamber communicates with the middle hole and radial hole and chute of the plunger head. After continuous movement in this working mode, continuous oil supply is formed. It relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil absorption and pressure. When the pressure is higher than the outlet pressure, The outlet valve opens and the liquid is discharged.

When the plunger is pulled out, the pressure in the working chamber decreases and the outlet valve closes. A plunger pump has two check valves with opposite directions.2020-09-24The working principle of the plunger pump The plunger pump is an important device of the hydraulic system.

After the oil inlet hole on the plug sleeve is opened, the diesel fuel filled in the upper body oil passage of the oil pump enters the pump oil chamber through the oil hole, the plunger moves to the bottom dead center, and the oil intake ends. When the plunger moves in one direction, negative pressure appears in the cylinder. Plunger pumps have the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment
