The pump housing is typically made from durable materials like cast iron or aluminum.
It encloses all the internal components of the pump, protecting them from external factors and ensuring the pump's longevity.
Piston Assembly:
The heart of the PVM Series pump is the piston assembly. This assembly includes a piston, piston rod, and a swashplate mechanism. The piston moves back and forth within a cylinder, creating the pumping action. The piston rod transmits this motion to the swashplate, which determines the displacement volume.
Swashplate Mechanism:
The swashplate mechanism is a critical component of the PVM pump. It consists of a swashplate that can be tilted to vary the pump's displacement and control the flow rate. Adjusting the swashplate angle regulates the output pressure and flow, allowing for precise control.
Inlet Port:
The pump has an inlet port where hydraulic fluid is drawn in from a reservoir or a hydraulic circuit. The inlet port connects to the suction line, and a filter is often installed to prevent contaminants from entering the pump.
Outlet Port:
The outlet port is where the pressurized hydraulic fluid is discharged, either into the system for further use or to actuate hydraulic cylinders and other components.
It connects to the hydraulic lines that distribute the fluid to the intended destinations.
Control Mechanism:
Many PVM Series pumps have provisions for various control mechanisms, such as pressure relief valves, load-sensing controls, and feedback devices. These controls are crucial for adjusting the pump's performance to match specific operational requirements.
Shaft and Bearings:
The pump is equipped with high-quality bearings that support the shaft and ensure smooth rotation. These bearings reduce friction and extend the pump's service life.
Seals and Gaskets:
To maintain the hydraulic fluid's integrity and prevent leaks, the PVM Series pump incorporates various seals and gaskets, including piston seals and shaft seals. These components play a critical role in maintaining the pump's efficiency and reliability.
Fluid Compatibility:
The PVM Series piston pump is designed to work with various hydraulic fluids, including hydraulic oil, synthetic hydraulic fluids, and more. It is important to use a fluid that is compatible with the materials used in the pump and that meets the system's requirements.
