Description

Multiple separation self priming pump Technical Field The application relates to the technical field of water pumps, in particular to a multiple separation self-priming pump. Background The self-priming pump has the advantages of wide application, simple structure and the like, so that the self-priming pump is widely applied to the fields of agricultural irrigation, chemical production, mineral transportation and the like. However, since the self-priming pump lifts water by suction force of vacuum formed by centrifugal force of the impeller, when the self-priming pump is started, the gate valve must be closed first to perform irrigation. Therefore, under emergency, the self-priming pump started for the first time is irrigated, the starting time is greatly prolonged, and the working efficiency of the self-priming pump is severely restricted. Disclosure of Invention In view of the shortcomings of the prior art, one of the objectives of the present application is to provide a multiple separation self-priming pump that has the advantage of shortening the priming time of the self-priming pump.
