What is the trapped oil phenomenon of the gear pump?

Page view
What is the trapped oil phenomenon of a gear pump? The hydraulic gear pump is composed of a pair of intermeshing gears that absorb and press oil by the meshing and separation of the gears during rotation to form a volume change. When the gears are meshed, the hydraulic oil between the engaged teeth is unable to be discharged due to the closing of the teeth, thereby forming a trapped oil phenomenon. The trapped oil generates high pressure, creates side pressure on the shaft, easily bends the shaft, prematurely damages the bearing, and also consumes the power of the motor.
 
The solution is to open a oil discharge groove to the oil discharge chamber on the side of the gear meshing portion, so that the oil trapped between the two teeth can be discharged to eliminate oil trapping.
