Hydraulic pump parts

Hydraulic pump parts mainly include various components for different types of hydraulic pumps. Hydraulic pump is a device that converts mechanical energy into hydraulic energy, its types mainly include gear pumps, piston pumps, vane pumps and screw pumps, etc., the components of various types of pumps are different, the following are some key parts of common hydraulic pumps:

First, Gear Pump parts:

1. Pump casing: accommodates and supports the gears.

2. Meshing gear: Usually includes a driving gear and a driven gear for pumping liquids.

3. Bearing: support gear rotation.

4. Seals: to prevent liquid leakage.

Second, Piston pump parts (positive displacement pumps):

1. Cylinder block: accommodates the plunger.

2. Plunger: reciprocating motion in the cylinder body, used to pump liquid.

3. Swash plate or rotating swash plate: adjust the stroke length of the plunger, so as to control the displacement.

4. Distribution plate: guide the liquid in and out of the pump.

5. Bearings and seals: ensure the normal operation of plungers and swash plates and other components and prevent leakage.

Third, Vane Pump parts (also Positive Displacement Pumps):

1. Rotor: The blades are mounted on it and rotate inside the pump chamber.

2. Blades: Rotate with the rotor to change the volume of the pump chamber to pump liquid.

3. Stator: Define the shape of the pump chamber.

4. End cap: Closes the pump chamber and supports the rotor and blades.

5. Seals: to prevent liquid leakage.

Fourth, Progressive cavity pump parts (positive displacement rotary lobe pumps):

1. Screw: A rotor with intermeshing threads for pumping liquids.

2. Pump casing: Houses the screw and supports its rotation.

3. Synchronous gear (sometimes): used to ensure the synchronous rotation of the two screws.

4. Seals: Prevent liquid from leaking from the gap between the screw and the pump casing.

In addition, various hydraulic pumps may include other parts such as drive shafts, bearings, seal kits, valve plates, retaining plates, etc., depending on the design and manufacture of the pump. When repairing or replacing hydraulic pump parts, it is advisable to refer to the manual or guide provided by the manufacturer of the pump to ensure that the required parts are properly identified and installed.
