A shaft-in-shaft centering rotor pump provided with sliding plates comprises a case, a rotor (4), a crankshaft (8), sliding plates (5) and blades (6). Due to the limitation of the crankshaft (8), the sliding plates (5) are prevented from being rubbed against the case under the inertia effect during rotation along with the rotor (4) so that the pump flow is large, the size is small, the efficiency is high, and the application range is wide. The pump is applicable to an oil pump, a water pump, a motor, a vacuum pump, a driving paddle and the like. |
