Abstract
The present invention relates to a rotor pump (10), comprising: a pump body (50A) capable of being rotatably driven and forming an accommodation cavity (52) therein; a pump wheel (20, 20A) having a main body part (22) capable of rotating in the accommodation cavity and a first shaft part (24) axially extending from the main body part; and a sealing plate (30) comprising an eccentric hole (32) being eccentric relative to the rotation axis of the pump body; the first shaft part is rotatably fitted in the eccentric hole; a suction channel (25) is formed on one side of the pump wheel, and a discharge channel is formed on the other side of the pump wheel; the suction channel and the discharge channel are respectively in fluid communication with a compression cavity formed between the outer circumference of the pump wheel and the inner circumference of the accommodation cavity. The present invention also relates to a rotary machinery comprising the rotor pump. The rotor pump of the present invention has a simple structure, fewer components and low cost.
