Abstract: |
The invention relates to a planetary cylinder plunger pump, which includes a cylinder; a group of pole blocking assembly matching with the cylinder; an eccentric spindle, and the center of the cylinder surrounds the revolving shaft center of the eccentric spindle; a round channel guide limiting the rolling of the cylinder; a groove guide device limiting displacement of the pole blocking assembly relative to the cylinder, the pole blocking assembly led by the groove guide device operates to-and-fro to form the chaining dimension and the working chamber of the pump and the motor. The revolving of the eccentric spindle brings the circle moving of the center of the cylinder, and the outer circle of the cylinder rolls on the inner circle of the channel guide and the pole blocking assembly moves to-and-fro relatively to the cylinder. |
