Belparts Excavator ZX160W 9227147 Hydraulic Main Pump For K5V80DTP-YXSKR-9K00

Belparts excavator ZX160W 9227147 hydraulic main pump for K5V80DTP-YXSKR-9K00

The hydraulic pump converts mechanical energy into hydraulic energy to power the excavator's hydraulic system. When the engine drives the pump shaft to rotate, the internal pistons or gear sets create oil suction and compression processes, forming a high-pressure oil flow. Belparts hydraulic pumps feature variable displacement design that automatically adjusts output flow according to load requirements, achieving high energy efficiency.

The hydraulic pump is a critical component in excavators, responsible for converting mechanical energy into hydraulic energy. It supplies high-pressure hydraulic oil to various actuators (such as hydraulic cylinders and motors), enabling smooth and efficient operation of the excavator. High-quality hydraulic pumps ensure durability, energy efficiency, and precise control, making them essential for construction, mining, and other heavy-duty applications.

Working Principle

The hydraulic pump operates based on the principle of positive displacement, where mechanical force (from the engine) drives the pump to create fluid flow. The key steps in its operation include:

• Suction Phase: As the pump’s internal mechanism (e.g., gears, pistons, or vanes) rotates, it creates a vacuum that draws hydraulic fluid from the reservoir.

• Compression Phase: The trapped fluid is pressurized as the pump’s moving parts reduce the chamber volume, forcing the fluid into the hydraulic system.

• Discharge Phase: The high-pressure fluid is delivered to control valves, cylinders, or motors to perform mechanical work.
