Rexroth A4V hydraulic pump is a high-performance axial piston pump, which is widely used in various industrial fields with its excellent working characteristics and reliability. So what are the Hydraulic Pump Parts for Rexroth-Uchida A4V?
Rexroth A4V hydraulic pump is mainly composed of pump housing, plunger, cylinder body, oil distribution plate and other components. Among them, the plunger and cylinder body are the core components of the pump. The plunger reciprocates in the cylinder body and realizes the conversion of hydraulic energy by sucking and discharging hydraulic oil.
Hydraulic Pump Parts for Rexroth-Uchida A4V mainly include: pump body, which constitutes the main structure, accommodates internal components, provides oil channels and installation interfaces. Drive shaft: connects to the motor or engine, transmits rotational power, and is usually made of high-strength alloy steel. Plunger (9 or more): reciprocates in the cylinder bore, and realizes oil suction and discharge by changing the angle of the swash plate.
Cylinder: Rotating component in which the plunger moves. The material must be wear-resistant and high-pressure resistant. Valve plate: Fixed to the pump body, responsible for switching between high and low pressure oil circuits. The surface must be precisely ground to ensure sealing. Swash plate: Adjustable tilt angle to control plunger stroke, thereby adjusting the pump displacement. The larger the angle, the higher the displacement.
Control piston: Hydraulically driven, pushing the swash plate to change angle. Servo valve: Responds to system pressure signal and adjusts the oil circuit of the control piston. Feedback spring: Balances control force, stabilizes the position of the swash plate, and assists system parts. Supports the drive shaft, withstands radial and axial loads, and commonly uses tapered roller bearings or angular contact bearings.
Shaft seal: Prevents oil leakage. O-ring/Gley ring: Static seal to ensure that there is no leakage on each connection surface. Pressure control valve: Including overload valve, pressure cut-off valve, etc., for system protection. Make-up pump (equipped with some models): Provides low-pressure replenishment for the closed circuit to maintain the suction pressure of the main pump. Key interface: Suction port: Connects to the oil tank, usually designed with a large diameter to reduce the flow rate. Pressure port: output high-pressure oil to the system. Drain port: discharge internal leaking oil to prevent excessive housing pressure.
The working principle of Rexroth A4V hydraulic pump is based on the reciprocating motion of the plunger. The plunger moves back and forth in the cylinder and controls the oil distribution plate to achieve the suction and discharge of hydraulic oil.
This design enables the pump to efficiently convert hydraulic energy to meet the needs of different industrial fields.
