Pump Housing: The pump housing is the outer casing that encloses the internal components of the hydraulic pump.
It is designed to provide structural integrity and protect the internal parts from external elements.
Swash Plate: The swash plate is a key component responsible for converting the rotational motion of the pump shaft into reciprocating motion. It consists of a tilted plate that slides back and forth, altering the displacement of the pump to control the flow rate and pressure.
Piston Block: The piston block contains multiple pistons that reciprocate within cylinders. These pistons are connected to the swash plate and convert the linear motion into hydraulic pressure. The number of pistons varies depending on the pump model and capacity.
Valve Plate: The valve plate acts as a distribution mechanism for hydraulic fluid within the pump. It contains various valves that control the flow of fluid to and from the piston cylinders. The valve plate is crucial for regulating the direction and pressure of the hydraulic fluid.
Drive Shaft: The drive shaft is connected to the power source, typically an engine or an electric motor. It transmits the rotational force to the pump, driving the swash plate and the pistons.
Bearings: The hydraulic pump incorporates several bearings to support the rotating shafts and minimize friction. These bearings ensure smooth operation and extend the lifespan of the pump.
Seals: Sealing components such as O-rings, gaskets, and shaft seals are used to prevent leakage of hydraulic fluid from the pump. They maintain the integrity of the hydraulic system and ensure efficient operation.
Pressure Relief Valve: The pressure relief valve protects the hydraulic system from excessive pressure.
It automatically opens to divert excess fluid back to the reservoir when the system reaches a predetermined pressure level, preventing damage to the pump and other components.
Flow Control Valve: Some models of the KOMATSU HPV Series feature a flow control valve that allows operators to adjust the flow rate of hydraulic fluid. This feature enables precise control over the hydraulic system, catering to different operational requirements.
Specifications: The specifications of the KOMATSU HPV Series pumps vary depending on the model and application. Key specifications include the maximum flow rate, maximum pressure, displacement volume, input power requirements, and physical dimensions. These specifications determine the suitability of the pump for specific machinery and operational conditions.
