Pump Housing: The pump housing is a vital component that encloses and protects the internal parts of the hydraulic pump.
It should be constructed with high-quality materials to withstand the pressures and stresses encountered in hydraulic systems. The replacement pump housing should be compatible with the A11VO series and designed to fit seamlessly with other components.
Cylinder Block: The cylinder block plays a crucial role in the hydraulic pump's operation, as it contains the pistons and valves responsible for fluid displacement. The replacement cylinder block must be manufactured with precision to ensure accurate piston movement and fluid flow. It should have the appropriate number of pistons and be designed to match the displacement requirements of the A11VO series.
Pistons: The pistons are responsible for generating the necessary hydraulic force by reciprocating within the cylinder block. When selecting replacement pistons, it is crucial to consider their size, material, and surface finish. The pistons should be made from high-strength materials such as steel or aluminum and have proper surface treatments to minimize friction and wear.
Valve Plate: The valve plate controls the flow of hydraulic fluid within the pump. It contains various channels and ports that direct the fluid to different parts of the hydraulic system. Replacement valve plates should be designed to match the specific configuration of the A11VO series and have precise tolerances to ensure efficient fluid flow and prevent leakage.
Shaft: The pump shaft connects the pump to the power source, typically an electric motor or an engine. It transmits the rotational motion and torque from the power source to the pump components. Replacement shafts should have the correct dimensions, keyways, and shaft ends to ensure proper alignment and engagement with the power source.
Bearings: Bearings provide support and reduce friction between moving parts within the hydraulic pump. They should be selected based on the load capacity, rotational speed, and operating conditions of the A11VO series. Replacement bearings should match the specifications provided by Rexroth and be manufactured to withstand the demands of the hydraulic system.
Seals and O-rings: Seals and O-rings are critical for preventing fluid leakage and maintaining the hydraulic system's efficiency.
Replacement seals and O-rings should be made from high-quality materials with suitable hardness, chemical resistance, and temperature tolerance. They should be compatible with the hydraulic fluid used and designed to fit the specific sealing grooves and clearances of the A11VO series.
Control Options: The A11VO series hydraulic pump offers different control options, such as pressure compensators, flow regulators, and load-sensing controls. When selecting replacement parts, it is essential to consider the desired control functionality and choose components that are compatible with the existing system or the intended system design.
