Gear oil pump structure description and characteristics

The gear pump (oil pump) works with two gears that are intermeshing and rotating, and the medium requirements are not high. The general pressure is below 6 MPa and the flow rate is large.
The gear oil pump is equipped with a pair of slewing gears in the pump body, one active and one passive, and the two working parts in the pump are divided into two separate parts by the mutual engagement of the two gears. A is the suction chamber and B is the discharge chamber. When the gear oil pump is in operation, the driving gear drives the driven gear to rotate. When the gear is engaged to disengage, a partial vacuum is formed on the suction side (A), and the liquid is sucked. The inhaled liquid fills the respective valleys of the gear and is brought to the discharge side (B). When the gear enters the mesh, the liquid is squeezed out to form a high-pressure liquid and exit the pump through the pump discharge port.

Gear pump features:
1. Compact structure, easy to use and maintain.
2. Has good self-priming, so there is no need to inject liquid before each pump is turned on.
3. The lubrication of the gear oil pump (oil pump) is automatically achieved by the liquid to be delivered, so there is no need to add lubricating oil for daily work.
Gear oil pumps are widely used in petroleum, chemical, marine, electric power, grain and oil, food, medical, building materials, metallurgical and national defense research. The gear oil pump (oil pump) is suitable for conveying lubricating oils without solid particles and fibers, non-corrosive, temperature not higher than 150 ° C, viscosity 5 to 1500 cst or other liquids similar in lubricating oil. Try various types of occasions where outdoor installation and process in the coagulation and alpine regions require heat preservation at room temperature.
