Three-in-one water pump

Abstract

The invention belongs to the technical field of water pump application, and specifically discloses a three-in-one water pump. The three-in-one water pump comprises a first screw, a sewage base, a pumpbody, a rear pump casing, a clean base, a second screw, a base, a first O-shaped ring, a lock nut, an impeller, a gasket, an oil seal, a front cover, a bearing, a spring, a shaft, a rotor core, a three-peak washer, a stator, a rear cover, a second O-shaped ring, a pressure buckle, a back cover, a capacitor, a handle cover, a sheath, a float and a cable, wherein the first screw, the sewage base, the pump body, the rear pump casing, the clean base, the second screw, the base and the first O-shaped ring are cooperatively used; the lock nut, the impeller, the gasket, the oil seal, the front cover, the bearing, the spring, the shaft, the rotor core, the three-peak washer, the stator, the rear cover, the second O-shaped ring, the pressure buckle, the back cover and the capacitor are arranged inthe pump body and the rear pump casing and are cooperatively used; and the handle cover, a sheath, a float and a cable are arranged on the rear pump casing. The water pump has the beneficial effectsthat the water pump is reasonable in overall structure design and wide in application range, and can be used in the total lift range, a float switch arranged on the water pump can automatically control the pump to be turned on and off according to the change of the water level, automatic action can be achieved, meanwhile, the functions a sewage pump, a clean water pump and a low suction water pumpcan be achieved through the water pump, and switching between various water pump functions is convenient and can be achieved by removing a screw.

Description

technical field [0001] The invention belongs to the technical field of water pump applications, and in particular relates to a three-in-one water pump. Background technique [0002] The water pump is a kind of machinery for conveying liquid, which converts the mechanical energy of the prime mover into the pressure energy of the liquid. Before the centrifugal water pump works, the vortex cavity must be filled with water; when the impeller rotates, the liquid in the middle of the blade rotates with the blade, and under the action of centrifugal force, the liquid flies away from the impeller and shoots outward; a vacuum and low pressure are formed at the center of the impeller In the area, the liquid in the liquid pool flows into the impeller through the inlet of the pump under the action of the external atmospheric pressure; while the liquid ejected from the impeller accumulates in the vortex cavity, and the pressure gradually increases, so that the liquid is pressed out from ...
