Abstract

The invention discloses a compound rotary polishing method of a centrifugal pump impeller. A polishing device matched with the polishing method comprises a base, a support, a barrel, an impeller body, transmission shafts, a current stabilizer, a water storage tank, a porous plate, a bottom drive device and a top drive device. The top drive device and the bottom drive device are controlled to operate; after operating for a period of time, the bottom drive device is automatically stopped and the top drive device is started; and after the top drive device operates for a period of time, a power source of the top drive device is stopped, such cyclic operation is performed, and automatic control is achieved. According to the compound rotary polishing method of the centrifugal pump impeller, the structure is simplified, the size is small, the polishing efficiency is high, and the cost is low.

Description

technical field [0001] The invention relates to a centrifugal pump impeller rotary polishing method, in particular to a centrifugal pump impeller compound rotary polishing method. Background technique [0002] At present, most of the centrifugal pump impellers in China still use the traditional sand casting process, and the surface of the impeller is usually rough. As the core component of the centrifugal pump, the impeller's roughness has a great influence on the performance of the unit. Reducing the roughness of the impeller surface plays a significant role in reducing the hydraulic loss in the impeller and improving the efficiency of the unit. In order to improve the quality level of the surface of the wetted parts, the impeller needs to be polished. When the impeller is ground and polished by the traditional manual process, because the blade is a three-dimensionally distorted curved surface, the strength and direction are not easy to control, the requirements for the f...
