Gear pump

Gear pump

 
The driving gear rotates, the gears in the oil suction chamber are disengaged, and the gear teeth exit between the teeth, which increases the sealing volume and forms a partial vacuum. The oil in the oil tank enters the gears through the oil suction pipeline and the oil suction chamber under the action of the external atmospheric pressure. between. As the gear rotates, the oil sucked between the teeth is taken to the other side and enters the oil pressure chamber. This is when the gears enter into meshing, which gradually reduces the sealing performance, and the oil in the gears is squeezed out, forming the oil pressing process of the gears. When the gear meshes, the tooth-direction contact line separates the oil suction chamber and the pressure oil chamber, and plays the role of oil distribution. When the driving gear of the gear pump is continuously rotated by the motor, the gear is disengaged from the meshing side. As the sealing volume becomes larger, oil is continuously sucked from the oil tank. Oil, forming a continuous cycle
