China PSVD2 Series Piston Pump Parts | Tonkee®

Piston Assembly: The piston assembly is at the heart of the PSVD2 pump.

It typically consists of a set of pistons arranged radially within the pump housing. These pistons are designed to reciprocate within cylinder bores. The size and number of pistons can vary depending on the specific model, but they are typically made from high-strength materials to withstand the pressures and forces generated during operation.

Cylinder Block: The cylinder block houses the pistons and rotates within the pump housing. It is a critical component responsible for generating hydraulic pressure. The cylinder block's size and design dictate the pump's displacement capacity and performance. Different models within the PSVD2 series may have varying cylinder block sizes and configurations.

Swash Plate: The swash plate is an inclined plate that is connected to the rotating cylinder block. It plays a vital role in controlling the piston stroke and, consequently, the pump's displacement. The angle of the swash plate determines the pump's output flow rate and pressure. It is typically adjustable, allowing for variable displacement to meet changing system requirements.

Control Valve: PSVD2 series pumps often feature a built-in control valve that regulates the swash plate angle. This valve can be manually adjusted or operated electronically, depending on the application's needs. Accurate control of the swash plate angle is essential for maintaining precise flow and pressure control.

Housing: The pump housing contains all the internal components and provides structural support

It is typically constructed from durable materials to withstand the rigors of hydraulic applications. The housing design is optimized for efficient fluid flow and heat dissipation.

Suction and Discharge Ports: These ports are integral to the pump's operation. The suction port allows hydraulic fluid to enter the pump, while the discharge port is responsible for delivering pressurized fluid to the hydraulic system. The size and location of these ports can vary based on the specific model.

Bearings and Seals: Bearings and seals are used to reduce friction and prevent fluid leakage within the pump. High-quality bearings ensure smooth rotation of the cylinder block, while seals maintain the integrity of the fluid path, preventing leaks and contamination.

Materials and Construction: The PSVD2 series piston pump is typically constructed from high-quality materials, such as hardened steel for the pistons and cylinder block. This ensures longevity and durability, even in demanding industrial environments.
