Replace Rexroth PR4 Hydraulic Piston Pump Principle

Replace Rexroth PR4 Hydraulic Piston Pump radial piston pump is a powerful operating piston pump in Rexroth piston valves, suitable for a variety of complex high-pressure operating environments, and has the characteristic of working at * working pressure (up to 700 bar). The volumetric flow rate of a single plunger can be applied to various work tasks.The  PR4-X3 radial piston pump is also a type of reciprocating pump and belongs to the volumetric pump category. The working principle of Rexroth plunger pump is that the plunger is driven by the eccentric rotation of the pump shaft, reciprocating motion, and its suction and discharge valves are both one-way valves. When the plunger is pulled out, the pressure inside the working chamber decreases and the outlet valve closes. When the pressure is lower than the inlet pressure, the inlet valve opens and liquid enters; When the plunger is pushed inward, the working chamber pressure increases, the inlet valve closes, and when it is higher than the outlet pressure, the outlet valve opens and the liquid is discharged. When the transmission shaft drives the cylinder to rotate, the inclined plate will push the plunger
Pull out or push back from the cylinder block to complete the oil suction and discharge process. The oil in the working chamber composed of the plunger and cylinder bore is connected to the suction and discharge chambers of the pump through the oil distribution plate. The variable mechanism is used to change the inclination angle of the inclined plate, and by adjusting the inclination angle of the inclined plate, the displacement of the pump can be changed.
