Hydraulic gear pump troubleshooting
Hydraulic gear pump is composed of a pair of intermeshing gear, through the gear meshing and separation of the tooth rotation to form a change in the volume of oil and oil 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, premature bearing damage, but also consume the motor power....

How to eliminate the trapped oil phenomenon of the hydraulic pump (piston pump vane pump gear pump)?
First, what is the phenomenon of hydraulic pump trapping oil? The closed working volume of the hydraulic pump forms a closed volume during the transfer to the pressure chamber after the oil is filled. If the size of the closed volume changes, when the dead volume changes from large to small, the oil in it is squeezed, the pressure rises sharply, the bearing is subjected to periodic pressure shock, and the oil is heated; When the volume is changed from small to large, vacuum is generated due to...
