Excavator Spare Parts Hydraulic Vane Pump

June 08, 2021

Excavator Hydraulic Vane Pump is a type of Hydraulic Pump used in construction machinery like excavators to transfer mechanical energy into hydraulic energy. This conversion is essential for the operation of various hydraulic systems on the excavator, such as lifting arms, digging buckets, and other attachments.

Here are some key points about the Excavator Hydraulic Vane Pump:

1. Function: The primary function of this pump is to pressurize hydraulic fluid (usually oil) which then powers hydraulic cylinders and motors in the excavator.

2. Design: A vane pump typically consists of a rotor, vanes, and a housing. The rotor is eccentrically mounted within the housing, creating chambers that change volume as the rotor turns. This volume change creates the pumping action.

3. Operation: As the rotor spins, centrifugal force pushes the vanes outward, maintaining contact with the housing. This creates varying chamber volumes, which draw fluid in and then push it out under pressure.

4. Benefits:

- Smooth operation due to the even distribution of hydraulic fluid.

- Lower noise levels compared to gear pumps.

- High efficiency and relatively low maintenance requirements.

5. Maintenance: Regular inspection and replacement of worn parts (such as vanes or seals) are important to maintain optimal performance and extend the life of the pump.

6. Replacement: If a vane pump fails, it needs to be replaced by a compatible model to ensure proper functioning of the excavator's hydraulic system.
