Product Detail

Pump Housing: The pump housing is the outer casing that houses the internal components of the main pump.

It is typically made of high-strength cast iron or steel to withstand the high pressures and loads experienced during operation. Drive Shaft: The drive shaft connects the main pump to the engine or motor, transmitting the rotational power required to drive the pump. It is a sturdy component usually made of alloy steel to handle the torque and rotational forces. Cylinder Block: The cylinder block contains a series of cylinders with pistons that generate hydraulic pressure. It is typically made of cast iron or steel and precision-machined to ensure smooth movement of the pistons. Pistons: The pistons are reciprocating components within the cylinder block that create hydraulic pressure. They are typically made of high-strength materials like steel or aluminum and are designed with seals to prevent fluid leakage. Valve Plate: The valve plate acts as a control mechanism for regulating the flow of hydraulic fluid within the main pump. It consists of various valves and ports that direct the pressurized fluid to different hydraulic functions. Swash Plate: The swash plate is a slanted or tilted plate connected to the drive shaft. It converts the rotational motion of the drive shaft into reciprocating motion of the pistons, generating hydraulic pressure. Bearings: The main pump utilizes various types of bearings to support rotating components and reduce friction. These bearings are typically made of high-quality steel and are designed to withstand heavy loads and high speeds.

Seals and O-rings: Seals and O-rings are essential for preventing fluid leakage within the main pump.

They are typically made of durable elastomeric materials and are strategically placed in critical areas to maintain hydraulic efficiency and performance. Shaft Seals: Shaft seals are used to prevent hydraulic fluid from leaking along the drive shaft. They are typically made of rubber or elastomeric materials and feature sealing lips to maintain a tight seal. Fasteners: Various bolts, nuts, and screws are used to secure and assemble the different components of the main pump. These fasteners are typically made of high-strength steel and are designed to withstand the operating conditions of the excavator.
