Gear pump trapped oil phenomenon Gear pump to work smoothly, gear meshing overlap factor must be greater than 1, so there are always two pairs of gear meshing at the same time, and part of the oil is besieged between two pairs of teeth formed by the closed cavity . This closed volume is constantly changing with the rotation of the gear. When the closed volume changes from large to small, the oil being sealed is squeezed and squeezed out of the gap to generate high pressure, the oil generates heat and the bearing receives an extra load. When the volume of the closed volume changes from small to large, , Will cause a partial vacuum, the gas dissolved in the oil separated, resulting in hole phenomenon. These will make the pump produce strong vibration and high noise, which is the gear pump trapped oil phenomenon. The method of eliminating the trapped oil phenomenon is usually to open the unloading trough on the cover on both sides so as to reduce the volume of the closed chamber to communicate with the pressurized oil chamber and to increase the volume of the oil chamber when communicating with the suction chamber.
