Research of Internal Leakage Theory Model in the Exterior Meshing Gear Pump

The popularization and promotion of In high pressure and high gear pump is slowing, the reason is not eradicate pressure leakage problems. Based on the gear pump CBZB2 series for research object, through theoretical analysis of internal leakage mechanism, influencing factors and leak leakage ways Summarizes the theoretical model of internal leakage have a great significance In the design of In high pressure and high gear pump.
