Abstract

The invention discloses a dual-output gear pump. The dual-output gear pump comprises a pump shell with a pump cavity, a driving gear, a first driven gear and a second driven gear are arranged in the pump cavity, the first driven gear and the second driven gear are both engaged with the driving gear, the axis of the first driven gear and the axis of the second driven gear are located on the same plane, the axis of the first driven gear and the axis of the second driven gear are symmetrically arranged about the axis of the driving gear, the pump shell is provided with a liquid inlet, a first liquid outlet and a second liquid outlet, a liquid inlet flow channel is further formed in the pump shell, the driving gear and the first driven gear form a first liquid suction area and a first liquid outlet area, the driving gear and the second driven gear form a second liquid suction area and a second liquid outlet area, and the first liquid outlet area and the second liquid outlet area have different liquid outlet flows. The gear pump can output different flows so as to adapt to different working conditions, and the application range of the gear pump is expanded.

Description

technical field [0001] The disclosure of the present invention relates to the technical field of gear pumps, in particular to a double-output gear pump. Background technique [0002] The gear pump is also called a positive displacement device, that is, like a piston in a cylinder, when one tooth enters the fluid space of the other tooth, the liquid is mechanically squeezed out. Because the liquid is incompressible, the liquid and the teeth cannot occupy the same space at the same time. The continuous meshing of the gears makes the gear pump output liquid continuously. [0003] The gear pump in the prior art has two gears meshing to output liquid, one of the two gears is the driving gear, and the other gear is the driven gear. Therefore, the force of the gear pump meshing with the two gears is uneven. , a gear pump with three meshing gears has appeared in the prior art, and driven gears are arranged on both sides of the driving gear. This scheme makes the gear pump evenly st...
