High performance clear water submersible pump

Abstract

A high-performance fresh-water submersible pump comprising a handle (3), a pump body (1) and an output-pipe connection head (2); the handle (3) is hinged on the top portion of the pump body (1); an inner wall of a pump body water outlet (2-1) connection end of the output-pipe connection head (2) has, hinged thereto, a unidirectional valve (5) capable of closing said pump body water outlet (2-1) connection end; one side of the outer surface of the pump body (1) has, connected thereto, a button (4) capable of top-opening said unidirectional valve (5); a support leg connecting rod (6), capable of vertically-reciprocating motion, is movably-connected within the pump body (1); a driving eccentric block (3-1), which drives and acts in concert with the support leg connecting rod (6), is provided below the handle (3); an automatic control switch assembly (11), which operates by means of the water pump and uses water level for controlling the activation or shutoff of the water pump, is also provided on the pump body (1). The present invention solves the technical drawbacks of traditional fresh-water submersible pumps whereby, during operation, liquid within a water-conveying pipe flows back into the pump body and operability is poor; the present invention has the advantage of effectively avoiding residual liquid flowing back into a pump body when the liquid in a deep well is close to being pumped dry.

Description

Technical field [0001] The invention relates to a water pump, particularly a high-performance clean water submersible pump. Background technique [0002] A submersible pump is a drainage machine whose pump body and motor can be immersed in water. The clean water submersible pump is one of the submersible pumps, which is suitable for the circulation and pressurization of clean water and softened water. [0003] The traditional clean water submersible pump is composed of a pump body, a submersible motor (including cables), a water delivery pipe and a control switch. The submersible motor is located in the pump body, and the water delivery pipe is connected to the water delivery port of the pump body. Its work is as follows: before the pump is turned on, the pump body must be filled with liquid; after the pump is turned on, the submersible motor drives the impeller to rotate at a high speed. The liquid in it rotates with the blades. Under the action of centrifugal force, it flies away...

AI Technical Summary

Problems solved by technology

[0004] In specific use, the above-mentioned traditional clean water submersible pump has the following disadvantages: 1) When the liquid in a deep well is about to be drained and no continuous liquid enters the pump body, the residual liquid in the water delivery pipe of the traditional clean water submersible pump It will flow back into the pump body, and then flow out from the suction port of the pump body, making it impossible to drain the liquid in the deep well; 2). The vertical distance between them cannot be adjusted, that is to say, the water inlet speed of the suction port on the bottom surface of the pump body cannot be adjusted, and the operability is poor; 3), the control switch part of the traditional clear water submersible pump cannot realize the submersible motor through whether there is liquid in the pump body. On and off control, poor control intelligence
