Water pump applied in narrow area

Abstract

The invention belongs to the technical field of water pump application and in particular discloses a water pump applied in a narrow area. The water pump applied in the narrow area comprises a pump body, a base, a bottom plate, locking screws, a capacitor, a micro switch, a switch fixing frame, a first cross recessed pan head tapping screw, a cable sheath, pressing buckles, pressing blocks, cross recessed pan head screws, a motor back cover, a three-wave-crest gasket, a stator, a rotor, a bearing, cables, a handle, a handle cover, a switch box, a third cross recessed pan head tapping screw, a shifting block, a shifting block buckle, a switch lever pressing buckle, a switch sheath, a float, a switch lever and the like, which cooperate with each other for use. The water pump has the advantages of being reasonable in overall design. The water pump is provided with a closed-type impeller, thereby being high in efficiency. The impeller is made of reinforced plastic, thereby being durable andhigh in surface hardness. The water pump is smooth, wear-resistant and good in sealing effect. The water pump has an automatic working mode and a manual working mode, thereby being capable of switching between the automatic working mode and the manual working mode by simply shifting a switching switch and capable of being applied in the narrow area.

Description

technical field [0001] The invention belongs to the technical field of water pump applications, and in particular relates to a water pump used in a narrow area. 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 water pump works, the vortex cavity must be filled with water; when the impeller is adjusted and rotated, 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, and the injected liquid accumulates in the vortex cavity , the pressure gradually increases, and it is raised from the outlet of the pump to achieve the purpose of pumping water. [0003] The submersible pump is used to extract liquid from other internal spaces such as containers and wells; the pump is often located in a relatively narrow working environmen...

Problems solved by technology

[0003] The submersible pump is used to extract liquid from other internal spaces such as containers and wells; the pump is often located in a relatively narrow working environment, while the conventional submersible pump is equipped with an external float switch, which requires a large space for the action of the float and cannot Suitable for working in narrow areas
