Radial Plunger Pump Attention
The oil distribution shaft is connected with the shell, and the oil flows in from two oil holes a in the upper part of the oil distribution shaft, and is pressed out from two oil holes in the lower part. For oil distribution, the oil distribution shaft processes the upper and lower two gaps in a section that is in contact with bushing 3, forming oil suction mouth b and oil pressure mouth c, and the remaining part forms the sealing oil area. The width of oil sealing area should be able to seal the oil suction and pressure hole on the bushing, in case the oil suction mouth and oil pressure mouth are connected, but the size should not be too large, so as to avoid oil trapping.
