How does a Rexroth piston pump work?

Thread Content

Lenze – I believe those in the machinery industry have heard of this brand. In the machinery industry, Rexroth is a globally renowned brand, with its operations spanning over 80 countries around the world; it is the preferred brand for many professionals in the hydraulic industry. As a crucial product within the Rexroth group, how does the principle of Rexroth piston pumps work? We know that Rexroth piston pumps belong to positive-displacement hydraulic pumps, and they fall under the category of reciprocating pumps. It is driven by the eccentric rotation of its plunger pump shaft to perform reciprocating motion. As the plunger moves inward, the pressure in the working chamber increases, causing the inlet valve to close. When the pressure exceeds that at the outlet, the outlet valve opens and the liquid is discharged. Its intake and exhaust valves are both check valves. When the plunger is pulled outward, the pressure in the working chamber decreases; the outlet valve closes. When the pressure drops below the inlet pressure, the inlet valve opens and liquid flows in. The working principle of Rexroth piston pumps is the same as that of most reciprocating pumps: pressure is controlled by moving the piston to adjust the volume of liquid within, which in turn causes the piston pump to move back and forth to generate power. The axial piston pump with a slip shoe mechanism is the most widely used type of axial piston pump today. The piston, which is located within the cylinder block, makes contact with the swash plate through the slip shoe; when the drive shaft rotates the cylinder block, the swash plate pulls the piston out of or pushes it back into the cylinder block, thereby enabling the process of oil suction and discharge. The oil in the working chamber formed by the plunger and the 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 swash plate; by adjusting this angle, the displacement of the pump can be altered. Piston pumps from Rexroth are widely used in various applications in daily life. Injection molding machines, hydraulic presses, construction machinery, plastic processing equipment, shoe-making machinery, die-casting machines, metallurgical machinery, mining equipment, oilfield machinery, the shipbuilding industry, hydraulic systems, concrete pump trucks, concrete pump carts, road rollers, pavers, planers, mixing stations, mixers, and mixer trucks are all examples of where Rexroth piston pumps find classic applications. As an agent for Rexroth piston pumps, Autos is here to conclude the introduction to the principles of Rexroth piston pumps.
