Guide you to understand how gear oil pumps suction pressure oil

When the driving gear rotates in that direction, the gear teeth in the low suction chamber separate from the gear teeth, and the volume of the sealing chamber continues to increase, forming a vacuum degree in the chamber. Injecting oil pressure into the oil suction chamber under normal pressure is called oil suction. As the gear rotates, the gear teeth filled in the direction of the arrow are brought into the exhaust chamber, and the teeth continue to enter the cavity, thereby reducing the volume of the oil discharge chamber (sealing chamber). Squeeze out the oil from the outlet and discharge it into the system. This is the working principle of the gear pump for oil suction and pressure oil. In the constant volume section, only oil is transported, and the gear pump does not require an oil distribution device, but it cannot change the oil.
