Product Description

The Caterpillar 374 and 390 F-Series excavators are two large excavators used in mining, large civil engineering and heavy-duty operations. The performance of these excavators relies in part on their efficient hydraulic systems, in which the hydraulic pumps play a vital role. Below is a detailed description of the Caterpillar 374/390 F hydraulic pump:

1.Structural features: These excavators typically use a variable displacement axial piston pump. This type of pump is capable of automatically adjusting the output flow rate according to the system requirements, providing precise flow control.Materials of construction for hydraulic pumps typically include high-strength steels and durable alloys to withstand high-pressure operating conditions and increase service life. In addition to the main pump body, the hydraulic pump system may include pressure control valves, flow control valves, relief valves, etc. to ensure system stability and reliability.

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: Detailed technical specifications of the hydraulic pump, such as flow rates, pressure ratings, and operational parameters, can be found in Caterpillar's official documentation specific to the 374F L/390F L model.

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.
