転制御装置。[Scope of Claim for Utility Model Registration] 1. A variable speed device that is provided with a detector on the suction side or the discharge side to determine whether the pump is in self-priming operation or pumped water operation, and which changes the pump rotation speed according to the detection result of the detector. An operation control device for a self-priming pump, characterized in that: 2. The self-priming pump operation control device according to claim 1, wherein the detector comprises a water detector attached to a suction side piping system including a pump suction section. 3. The self-priming pump according to claim 1, wherein the variable speed device is configured such that the pump rotation speed is high during self-priming operation and low speed during pumping operation. Operation control device. 4. The self-priming pump operation control device according to claim 1, wherein the detector comprises a pressure detector attached to a discharge side piping system including a pump discharge section.
