Yulin hydraulic axial gap is too large maintenance units, leakage volume, will reduce the volumetric efficiency; but the gap is too small, increase the mechanical friction losses between the gear end and the end cap, will reduce the mechanical efficiency of the pump. Therefore, the design must be strictly controlled and the axial clearance of the pump manufacturing. National Hydraulic system maintenance and fault diagnosis technology ① training gear pump leakage  there are three possible leakage areas: between the gear end and end caps; between the gear and the housing bore and the outer surface of the teeth of the two gears meshing. Where the greatest impact on the leakage is an axial gap between the gear end and cover Yulin hydraulic repair factory, through leakage axial clearance of total amount of leakage can be 75 to 80 percent, because here a short leak paths, a large area of ??the leak.
