China HPV90(PC200-5) KOMATSU Hydraulic Pump Parts | Partsdic®

Pump Type: The HPV90 is a variable displacement axial piston pump.

This means it can adjust the volume of hydraulic fluid it delivers, making it highly versatile for different operating conditions.

Displacement: The HPV90 typically has a displacement of 90 cc/rev (cubic centimeters per revolution). This measurement refers to the amount of hydraulic fluid the pump can deliver with each revolution.

Pressure Rating: The hydraulic pump is designed to operate under high pressure conditions. It can handle pressures in the range of 2800 to 3000 psi (pounds per square inch) or approximately 193 to 207 bar.

Flow Rate: The flow rate of the HPV90 pump depends on the engine speed and the demand of the hydraulic system. It can deliver variable flow rates to meet the specific needs of the excavator.

Drive Shaft: The pump is driven by the engine through a drive shaft, which transfers the mechanical power to the pump's internal components.

Control Mechanism: The HPV90 pump is equipped with a control mechanism that adjusts the displacement of the pistons to regulate the flow of hydraulic fluid. This allows for precise control of the excavator's movements.

Piston Assembly: The heart of the hydraulic pump is the piston assembly. It typically consists of multiple pistons arranged in a circular pattern. These pistons move in and out of their cylinders to create the pumping action.

Swashplate: The swashplate is an essential part of the axial piston pump.

It tilts in response to the control mechanism, which in turn changes the angle of the pistons and regulates the flow of hydraulic fluid.

Housing: The pump's housing contains all the internal components, providing protection and support. It is designed to withstand high pressures and maintain the integrity of the hydraulic system.

Ports: The HPV90 pump has inlet and outlet ports that connect to the hydraulic lines of the excavator. The inlet port draws hydraulic fluid from the reservoir, while the outlet port delivers pressurized fluid to the hydraulic circuit.

Bearings and Seals: Bearings are used to support the moving parts within the pump, while seals prevent leakage of hydraulic fluid. Proper lubrication and sealing are crucial for the pump's longevity and performance.
