Gear pump trapped oil phenomenon, eliminate gear pump trapped oil phenomenon

This article introduces the gear pump common problems: gear pump trapped oil phenomenon, and how to eliminate the gear pump trapped in oil phenomenon Hydraulic gear pump is a pair of intermeshing gears, through the gear meshing and separation of teeth in the rotation to form a volume Change and absorb oil and pressure. When the gear meshing, the meshing between the two teeth of the hydraulic oil due to the closure of the teeth can not be discharged to form a trapped oil phenomenon. Trapped oil will produce high pressure, side pressure on the shaft, easy to bend the shaft, bearings premature damage, but also consume the motor power. Gear pump trapped oil solution: the gear engagement at the side of the discharge chamber to open a discharge groove, so trapped in the oil between the two teeth can be discharged to eliminate the trapped oil phenomenon.
