Abstract
The utility mode discloses a self-priming pump structure comprising a bearing body installed on a pump body .The front end of the bearing body is provided with a mechanical sealing base, the bearing body is internally rotatably provided with a rotating shaft, the front end of the rotating shaft sequentially passes through the bearing body and the mechanical sealing base and then extends into the pump body, a mechanical seal is arranged between the rotating shaft and the mechanical sealing base, and the front end of the rotating shaft is fixedly sheathed with an impeller. Free of moving and slipping phenomena, the service life of water pumps is prolonged. ,Adjustment of balance is easy in installation, thus being beneficial to improving the installation efficiency of workers. The self-priming pump structure is suitable for promotion and application in the field of sealing devices of self-priming pumps.
Description
Technical field:
The utility model relates generally to the self prime pump field, relates in particular to a kind of self prime pump structure.
Background technique:
