Housing: The housing of the Hitachi HPV Series is made of high-quality materials to ensure durability and resistance to external elements.
It provides a sturdy enclosure for the internal components and facilitates easy installation and maintenance.
Cylinder Block: The cylinder block is a crucial part of the axial piston pump, responsible for generating the hydraulic pressure. Hitachi HPV Series pumps utilize a precisely machined cylinder block that houses several piston bores arranged in a circular pattern.
Pistons: The HPV Series features multiple pistons that reciprocate within the cylinder block. These pistons are designed to withstand high pressure and ensure efficient hydraulic fluid displacement. The pistons are typically made of durable materials, such as steel or aluminum alloys, to ensure longevity.
Valve Plate: The valve plate is located between the cylinder block and the swash plate. It contains a series of valves that control the flow of hydraulic fluid to and from the pistons. The valve plate ensures smooth and precise operation of the pump by regulating the timing and direction of fluid flow.
Swash Plate: The swash plate is a vital component responsible for converting the rotational motion of the drive shaft into reciprocating motion of the pistons. The angle of the swash plate determines the displacement volume of the pump, allowing for variable flow control. Hitachi HPV Series pumps offer adjustable swash plates, enabling flexibility in system requirements.
Drive Shaft: The drive shaft connects the pump to an external power source, such as an electric motor or an engine. It transmits the rotational energy to the pump's internal components, driving the fluid displacement process. Hitachi HPV Series pumps are designed to accommodate various drive shaft configurations, providing compatibility with different power sources.
Bearings: The HPV Series incorporates high-quality bearings to support the rotating components, such as the drive shaft and the swash plate. These bearings ensure smooth operation and minimize frictional losses, enhancing the overall efficiency and lifespan of the pump.
Seals: Seals play a crucial role in maintaining the hydraulic fluid integrity within the pump.
Hitachi HPV Series pumps utilize advanced sealing technologies to prevent leakage and contamination. These seals are designed to withstand high pressures and provide long-lasting performance, even in demanding operating conditions.
Control Options: The Hitachi HPV Series offers different control options to meet specific application requirements. These options include manual, hydraulic, or electro-hydraulic controls for adjusting the swash plate angle and regulating the pump's flow output. The availability of multiple control options enhances the versatility and adaptability of the pump.
Integrated Safety Features: Hitachi prioritizes safety in their HPV Series pumps. These pumps incorporate safety features such as pressure relief valves and temperature sensors to protect the system from overpressure and overheating. These features help prevent damage to the pump and ensure safe operation in various environments.
