2 month ago
Product details
The Caterpillar 320GC is a common excavator model, and the hydraulic pump is one of the key components in its hydraulic system. Below is a brief description of the hydraulic pump on the Caterpillar 320GC excavator
1.Structural features: Plunger pump: Hydraulic systems usually use axial piston pumps, by the plunger, plunger sleeve, rotor and cylinder and other components. Cylinder Block: Includes the plunger bore and inlet/outlet channels, which are used to accommodate the plunger assembly and form the hydraulic chamber. Swash Plate Assembly: Controls the movement of the plunger to regulate pump output flow and pressure. Bearings and Seals: Ensure stable operation and internal sealing of the pump.
2.Functionality &Adaptability :High performance: these pumps are designed to provide the necessary hydraulic oil flow at a low engine speed, optimising fuel efficiency.Through an advanced control system, the pumps are able to automatically adjust oil flow and pressure according to the different demands of excavator operation, ensuring smooth and precise operation.The design takes into account the demands of long-time operation and harsh working environments, ensuring the reliability and durability of the pump.
3.Principle of operation: The hydraulic pump receives power from the engine through rotary power, pumps and pressurises hydraulic fluid from the tank, and then delivers the pressurised hydraulic fluid to various parts of the system to drive hydraulic actuating components such as hydraulic cylinders and hydraulic motors.
4.Technical Specifications: Caterpillar 320GC hydraulic pumps are widely used in excavators and other heavy construction machinery to provide hydraulic power to drive hydraulic actuators to complete various work tasks.
5.Maintenance: Regular maintenance of the hydraulic pump is essential for ensuring optimal performance and longevity of the excavator. This may include monitoring fluid levels, checking for leaks, and inspecting pump components.
