One annular groove is located at the inside of first bulge loop, is provided with the second annular groove and the second bulge loop in the lower case, described second is convex
Ring is located at the inside of second annular groove, and second annular groove and first bulge loop are interference fitted, first annular groove and institute
State the second bulge loop interference fit.
Further, impeller is provided in the shell, the impeller is connected with main shaft, and the main shaft is connected with motor.
Further, the double entry pump further includes speed probe corresponding with the main shaft, the speed probe
It is connected with single-chip microcontroller, the single-chip microcontroller connects power supply, temperature sensor, combined aural and visual alarm, wireless communication module and the motor,
The wireless communication module is connected with mobile phone terminal, and the temperature sensor is located in the water inlet pipe.
Further, gasket is provided between the upper housing and the lower case.
The utility model has the beneficial effects that sealing effect is good, it is not susceptible to reveal, there is the function from start and stop.
