Working principle
Gear pump realizes oil suction and oil pressure based on "volume change". The specific process is as follows:
1. Oil suction process: When the driving gear rotates, it drives the driven gear to mesh and rotate in the opposite direction. On one side of the gear meshing point (oil suction chamber), the gear tooth groove gradually disengages, the volume between the teeth increases, and a local vacuum is formed. Under the action of atmospheric pressure, the hydraulic oil in the oil tank enters the oil suction chamber through the oil suction pipe and fills the tooth groove.
2. Oil pressure process: The gear continues to rotate, and the hydraulic oil in the tooth groove is brought to the other side of the meshing point (oil pressure chamber). At this time, the gear gradually enters meshing, the volume between the teeth decreases, and the hydraulic oil is squeezed out of the oil pressure chamber and transported to the hydraulic system through the oil pipe to realize the transmission of pressure energy.
The core is to use the periodic change of the volume between the teeth when the gears are meshing (increase → oil suction, decrease → oil pressure) to complete the suction and discharge of hydraulic oil and provide power for the hydraulic system.
