Brine submerging electric pump

Abstract

The invention discloses a brine submerging electric pump. The brine submerging electric pump comprises a brine submerging motor, a brine submerging pump located above the brine submerging motor, and a water input joint connected between the brine submerging pump and the brine submerging motor. A water input net cover is arranged on the outer circumference face of the water input joint in an enclosure manner. The water input joint comprises an upper flange, a lower flange, and two or more connecting pipes connected between the upper flange and the lower flange. A water input connector is arranged on the outer circumference face of the upper flange. A fresh water filling opening is formed in the water input connector. The upper flange is provided with a fresh water runner communicating with the fresh water filling opening. An upper water spraying hole communicating with the fresh water runner is formed in the inner circumference face of the upper flange. A water input through hole communicating with the fresh water runner is formed in the lower end face of the upper flange. The upper end of a connecting pipe is fixedly connected with the lower end face of the upper flange. The connecting pipe communicates with the water input through hole. A middle water spraying hole is formed in the middle section of the connecting pipe. A lower water spraying hole is formed in the lower section of the connecting pipe. The brine submerging electric pump is more reasonable in structure, brine can be effectively restrained from being crystallized in the water input joint, and the service life of the brine submerging electric pump is ensured.

Description

technical field [0001] The invention relates to the technical field of a submersible pump, in particular to a submersible halogen electric pump. Background technique [0002] The submersible brine electric pump is a submersible pump used for the extraction and discharge of brine, seawater and other similar corrosive media. It is often used in salt fields. The brine submersible electric pump includes a brine submersible motor, a brine submersible pump located above the brine submersible motor, and a water inlet section connected between the brine submersible pump and the brine submersible motor. The outer circumference of the water inlet section is surrounded by a water inlet net. The submersible brine pump consists of a diversion casing, a pump shaft and an impeller arranged in the diversion casing. The halogen submersible motor includes a casing, a stator assembly, a rotor assembly and a motor shaft arranged in the casing. An upper guide bearing seat and a lower guide bear...

Problems solved by technology

In the actual working environment, brine, seawater and other similar corrosive media often contain mud and sand. In the case of large sand content, the mechanical seal will be damaged quickly and lose its sealing function, resulting in the loss of clean water in the motor and external corrosive media. The intrusion of the existing submersible halogen electric pump motor reliability needs to be further improved
