Between the gear end and end caps; between gears turning and the housing bore and the meshing of the two gears. Where the greatest impact on the leakage is an axial gap address Hancheng hydraulic repair gear end and cover between the axial clearance by the leakage of the total amount of leakage can be 75 to 80 percent, because here a short leak paths, a large area of ??the leak . The axial gap is too large HANCHENG hydraulic maintenance units, leakage quantity, would reduce volumetric efficiency; but the gap is too small hydraulic repair HANCHENG mechanical friction loss, and the end cap between the end face of the gear increases, the mechanical efficiency of the pump will decrease . Therefore, the design must be strictly controlled and the axial clearance of the pump manufacturing. ② trapped oil gear pump hydraulic want steady work Seoul repair quote, overlap coefficient gear must be greater than 1, 5) self-lubricating hydraulic transmission equipment and automatic protection against over-loaded, safety and reliability. 6) Hydraulic equipment to maintain a good technical condition, it must be done to control pollution, leakage control, temperature control and control of cavitation. 7) As the hydraulic equipment delivered by the implementing agencies force, velocity, displacement can be adjusted so quickly adapt controlled parameter changes.
