| Product Name | Excavator Hydraulic Pump |
| Brand | belparts |
| Machine model |
ZX160W

| Part Number |
9227147 |
| Pressure | Standard, High Pressure |
The hydraulic pump of an excavator is the core component of the hydraulic system, providing power to the entire system like a heart. It converts the mechanical energy of the engine into hydraulic energy, drives the hydraulic cylinder and hydraulic motor to work, and thus completes various actions of the excavator.
Two types
Gear pump: With a simple structure, low cost, and strong anti pollution ability, but with large flow pulsation and high noise, it is mostly used in small excavators or auxiliary systems.
Piston pump: with complex structure and high cost, but high working pressure, large flow rate, high efficiency, and high control accuracy, it is widely used in medium and large excavators.
Working principle
Oil suction process: The plunger moves backwards, the pump chamber volume increases, forming a vacuum, and the hydraulic oil in the oil tank enters the pump chamber under atmospheric pressure.
Oil pressure process: The plunger moves forward, the pump chamber volume decreases, the hydraulic oil is compressed, the pressure increases, the oil outlet valve is pushed open, and high-pressure oil enters the hydraulic system.
