Housing: The pump housing is a robust and durable casing that houses all the internal components of the pump.
It provides protection and support to the internal parts and ensures their proper alignment and functioning.
Drive Shaft: The drive shaft is a critical component that connects the pump to the driving mechanism, typically an electric motor or an engine. It transmits the rotational motion to the pump assembly, initiating the hydraulic power generation process.
Cylinder Block: The cylinder block is a key component responsible for the axial movement of the pistons. It consists of several cylinder bores, each containing a piston and a set of valve plates. As the drive shaft rotates, the cylinder block moves axially, causing the pistons to reciprocate within their respective bores.
Pistons: The pistons are cylindrical components that move back and forth within the cylinder bores. They are actuated by the axial movement of the cylinder block. The pistons' motion creates a reciprocating action, which results in the conversion of mechanical energy into hydraulic pressure.
Valve Plates: The valve plates are located between the cylinder block and the housing. They contain a series of channels and ports that control the flow of hydraulic fluid. The valve plates play a crucial role in directing the fluid to the appropriate areas within the pump, ensuring proper functioning and efficiency.
Swash Plate: The swash plate is a key component responsible for adjusting the pump's displacement and flow rate. It consists of a tilted plate connected to the drive shaft. By changing the angle of the swash plate, the displacement of the pump can be altered, allowing for variable flow output.
Control Mechanism: The control mechanism of the A10VO Series pumps enables precise control over the pump's operation.
It typically includes a control piston, control springs, and a servo mechanism. The control mechanism adjusts the position of the swash plate based on the system requirements, regulating the pump's output accordingly.
Suction and Discharge Ports: The pump has dedicated suction and discharge ports for the hydraulic fluid. The suction port draws in fluid from the reservoir, while the discharge port delivers the pressurized fluid to the hydraulic system.
Seals and Bearings: The A10VO Series pumps incorporate various seals and bearings to ensure proper sealing and smooth operation. These components minimize leakage and friction, enhancing the overall efficiency and longevity of the pump.
