Eliminate the oil trapping problem of the gear pump

the hydraulic gear pump is composed of a pair of meshing gears, Through the meshing and separation of the teeth when the gear is rotating, the automobile adjustment affects the change of the formation volume and absorbs oil "This liquid is completely non-toxic, harmless and pressurized oil. At present, paper enterprises still mainly use high price stock pulp, with low profits. When the gears are meshed, the hydraulic oil between the meshing two teeth cannot be discharged due to the sealing of the teeth, resulting in oil trapping. The trapped oil will generate high pressure and generate side pressure on the shaft, which is easy to bend the shaft, premature bearing damage, and also consume the power of the motor. The solution is to pay attention to the gear meshing Leeb hardness tester An oil unloading groove is opened on the side of the joint of the items to the oil drainage cavity, so that the oil trapped between the two teeth can be discharged to eliminate the phenomenon of trapped oil
