Replaceable multi-stage centrifugal pump supporting structure

The utility model discloses a replaceable multistage centrifugal pump supporting structure in the field of multistage centrifugal pumps, which comprises a supporting seat, a multistage centrifugal pump main body and an adjusting mechanism, the multistage centrifugal pump main body is fixedly connected to the middle position of the top of the supporting seat through a connecting mechanism, and the adjusting mechanism is fixedly connected to the bottom of the supporting seat. According to the replaceable multi-stage centrifugal pump supporting structure, when the replaceable multi-stage centrifugal pump supporting structure is replaced, a pulling plate only needs to be pulled to drive a pulling rod to move, so that a clamping block moves, fixing of a connecting plate is relieved, then fixing of a multi-stage centrifugal pump body is relieved, dismounting is convenient, during mounting, the connecting plate is embedded into a connecting groove, and the inclined surface of the clamping block is extruded through t
