Structure and working principle of spur gear pump

Spur gear pump is a common hydraulic pump widely used in various industrial equipment. The following is a detailed introduction about spur gear pumps:

 

1. Basic structure

 

The spur gear pump mainly consists of the following parts:

 

Active gear: Driven by an electric motor or engine, it drives the driven gear to rotate.

 

Driven gear: meshes with the driving gear and rotates with the driving gear.

 

Pump body: accommodates gears and hydraulic oil, forming a sealed working chamber.

 

Import and export: used for suction and discharge of hydraulic oil respectively.

 

 

2. Working principle

 

The working principle of a spur gear pump is based on the meshing and separation of gears:

 

Inhalation process: As the gears rotate, the meshing points gradually separate, forming a local vacuum, and hydraulic oil is sucked into the pump.

 

Discharge process: As the gear continues to rotate, the meshing point gradually approaches and the hydraulic oil is discharged from the outlet.
