Water storage cavity and the second water storage cavity connecting portion are provided with internal non-return valve block, and impeller is provided with second water storage cavity, described
Impeller passes through rotary shaft and the motor connection.
Further, connected between the front pump shell and intermediate pump shell, between intermediate pump shell and rear pump shell by multiple bolts
Connect, the bolt is looped around on the front pump shell, the intermediate pump shell and the rear pump shell.
Further, the rear pump shell is connected with each other with the motor by the electric machine support, the electric machine support
Both ends are bolted connection with the rear pump shell, the motor respectively, and the rotary shaft is arranged in electric machine support.
Further, the bottom of the motor is provided with plastics lower margin.
Further, the self-priming pump case is elliptical configuration.
It is compared with the prior art, a kind of Self-priming pump provided by the utility model, its advantage is：
A kind of Self-priming pump of the utility model, while the first water storage cavity and the second water storage cavity are set, twice are set to stop
Inverse valve block, water can be effectively stored in the first water storage cavity and the second water storage cavity after shutdown, good seal performance, and moisture storage capacity is big,
So as to ensure still to keep higher negative pressure of vacuum in self priming pump after shutting down, the utility model Self-priming pump energy after starting shooting again
Quick start absorbs water, and so as to need the troublesome operation of artificial plus water ability self-priming when avoiding and shutting down and be again started up, improves water pump
Efficiency, add the water absorption of self priming pump.Because pump inner storing water amount is big, sealing device has sufficient cooling, is truly realized machine
Tool sealing is hardly damaged, and realizes the self priming pump that can be dallied.Simultaneously the self-priming pump case in the utility model include front pump shell, in
Between pump case and rear pump shell, easy access and cleaning when dismantle, reduce hand labor intensity.
