Why gear pump radial unbalanced force? Gear pump work, the role of the gear on the outside pressure is uneven. In the pressure oil chamber and the oil sump cavity respectively withstand the system operating pressure and suction pressure; gear tip circle and the pump bore radial clearance, you can think of the oil pressure by the pressure of the oil chamber down to Suction chamber pressure. The combined effect of these liquid pressures is equivalent to giving the gear a radial unbalanced force that causes the gear and bearing to be loaded. The greater the work pressure, the greater the radial unbalanced force, serious will cause the tooth top and the pump body contact, resulting in wear and tear. Usually reduce the pressure port to reduce the radial imbalance force, so that only high-pressure oil in the range of one to two teeth. External gear pump high pressure chamber (pressure oil chamber) of the pressure oil to the low pressure chamber (oil sucking chamber) there are three leaks: First, through the gear meshing gap, the second is the pump body surface and addendum between the radial clearance, Third, through the gear both ends of the end cap on both sides of the axial gap between the end. Among the three paths, the leakage of the axial clearance at the end face is the largest, accounting for 70% ~ 80% of the total leakage. Therefore, the lower volumetric efficiency of ordinary gear pump, the output pressure is not easy to increase. To raise the pressure on the gear pump, the primary problem is to reduce the end face axial gap.
