Double hydraulic pump

The double hydraulic pump is an assembly that boosts oil by the transmission of a pair of gears. There is a pair of gears in the pump body, the shaft gear is the driving wheel, and the shaft gear is the passive wheel. Power is input from the driving wheel, thereby driving the driven wheel to rotate together. When rotating, a partial vacuum is formed on the left side of the gear meshing area.The pressure is reduced and the oil is sucked into the pump.The gear continues to rotate.The sucked oil is transported to the right of the meshing position along the inner wall of the pump body. Deliver to parts that need lubrication.

0010010 nbsp; 0010010 nbsp; Anti-leakage: In order to prevent the double hydraulic pump from leaking, there is a sealing gasket at the junction of the pump body and the pump cover (The joint surface is the same), the packing gland leakage prevention device at the end of the driving shaft gear is composed of packing and packing gland bolt group

Disassembly and assembly sequence: pump body--active shaft and passive shaft--washer, pump body positioning pin, a screw--filler--gland

Tolerance coordination between parts of double hydraulic pump

  1. The distance between the gear end face and the pump body and pump cover is 32 K 6;

  2. The circle of tooth tip and the inner hole of the pump body are medium 48 H 7 / d 7;

  3. The two supporting shafts of the driving shaft gear, the passive shaft gear and the pump body, and the bottom shaft hole of the pump cover are medium 16 H 7 / h 6;

  4. The diameter of the packing gland and the pump body is medium {{1}} H 11 / dl 1.

Other technical requirements

  1. After assembly, it should rotate flexibly without jamming;

  2. The unprocessed outer surface is painted green after assembly.
