Abstract
The utility model relates to a cam blade rotor pump, comprising a pump body, left and right pressing boards, left and right pump covers, a main shaft, a driven shaft and a gear driving device. The main shaft and two driven shafts are arranged in the pump body in a star shaped way. The main shaft in the working cavity of the pump is symmetrically fixed and connected with a pair of blade baffle plates to form a main rotor, two driven shafts are symmetrically provided with a circular arc groove to form a driven rotor, and the main rotor and the driven rotor form a cam type rotor, simultaneously driving and rotating. The main rotor and the driven rotor are matched for working, the volume change is formed in the working cavity of the pump, and the pump body is provided with a heat preservation interlayer. The utility model has reasonable structure, stable flow quantity, strong self-sucking ability, low noise, high efficiency and long service life, and is suitable for the industries such as oilfield, chemical engineering, foodstuff, etc. The utility model is specially suitable for transporting the viscous medium.
