A pump in the middle water inlet pipe

Abstract

The invention relates to a middle water inflow pump in pipe. The middle water inflow pump in pipe comprises a submersible motor connecting plate and further comprises a water outflow adapter, a roundinside and square outside flange, a fastening sealing part, a sleeve, a water inlet, a guiding partition, a line outlet, a semicircular guiding adhesive tape, the submersible motor connecting plate, U-shaped damping and guiding adhesive tapes, an end blind plate with a flange and an overhead motor support. A groove for being connected with an external pipeline is formed in the upper end of the water outflow adapter, an internal threaded coupling for being connected with a deep well submersible pump is arranged at the lower end of the water outflow adapter, and the round inside and square outside flange is welded to the middle of the water outflow adapter. The two U-shaped damping and guiding adhesive tapes are symmetrically arranged on the outer wall of the motor in the axial direction, and the end blind plate with the flange is arranged at the lower end of the sleeve. The overhead motor support is arranged on the end blind plate with the flange and located in the sleeve. The heat dissipation efficiency of the motor is improved, the pump head is increased, and the middle water inflow pump in pipe can be widely applied to the technical field of water pumps.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a pump in a middle water inlet pipe. Background technique [0002] Due to the natural characteristics of water cooling, the deep well submersible pump makes the heat dissipation efficiency of the motor very high, so that the deep well submersible pump has higher efficiency than other air-cooled water pumps. The pump in pipe is a casing added to the deep well submersible pump, so that it has the characteristics of a conventional water pump. It can be widely used in building water supply and industrial water supply industries. It has the advantages of quietness, energy saving, and flexible installation methods. Although the pump in pipe has many advantages, its disadvantages are also obvious. Since the water inlet of the deep well submersible pump is located in the middle between the motor and the pump body, and the characteristics of the conventional pump in the pipe, one end...

AI Technical Summary

Problems solved by technology

Since the water inlet of the deep well submersible pump is located in the middle between the motor and the pump body, and the characteristics of the conventional pump in the pipe, one end of the water inlet and the other end of the water outlet, the water inlet and the motor share the water flow channel, and the motor occupies a large space, which leads to the casing of the pump in the pipe. The diameter is correspondingly enlarged, and the water inlet efficiency is not high. There is still room for optimization of the pump body of the pump in the pipe; the pump body of the pump in the pipe is thin and long, and the height of the pump is often too high when it is installed vertically, especially in high-lift applications. , plus the installation height of other pipe fittings and valves, it is even necessary to increase the floor height of the pump room, and it is inconvenient to operate the valve at the water outlet; when it is installed horizontally, it occupies too much space, occupying the plane space of the pump room and is easy to wear the bearings
