Numerical Simulation of the Influence of Gear Rotation Speed on the Gear Pump Flow Field

Abstract:

Gear pump has simple structure, long service life, strong self-priming capacity, high working reliability and other characteristics, which is widely used in various kinds of mechanical equipment. In order to study the influence of gear rotational speed on the internal fluid flow field change rule, the computational fluid dynamics software Fluent was used to simulate the gear pump flow field, while dynamic grid technique was carried on the numerical simulation of the gear pump under different rotation speed, and flow field characteristics were analysed. The results showed that with the increase of gear rotation speed, the area of pump fluid velocity mutation decreased, the area of pressure mutation reduced, and the larger volume of fluid closed to balance.
