Underground brine collection and transport dedicated pump and its production method

Abstract

The invention provides a special pump for collecting and transporting underground bittern and a process for preparation. The pump comprises an impeller, a water inlet part, and a submersible motor from top to bottom, and is penetrated by a pump shaft. The pump is characterized in that the impeller is designed into a semi-open impeller structure, a diversion core is arranged on the upper portion of the impeller, a guide blade is mounted on a conical face of the diversion core, a diversion casing is arranged on the peripheries of the diversion core and the guide blade, a water jacket is arranged on the periphery of the submersible motor, a fresh water intake pipe is arranged on the lower end of the water jacket, a fresh water spray hole is arranged on the conical bottom of the water inlet part, and motor metal bearings are respectively arranged on the upper portion and the lower portion of the submersible motor. The invention polishes each over-current surface, reduces the rotary speed of the motor, and arranges the water jacket on the periphery of the submersible motor, and fresh water are transferred into the water jacket to positively cool up the motor. The invention has high working efficiency, low operation costs, and saves fresh water resource, retards the crystallization velocity of bittern on the over-current surface, and increases five times of operation life.

Description

technical field [0001] The invention relates to a pump and its manufacturing method, in particular to a special pump for collecting and transporting underground brine and its manufacturing method. Background technique [0002] Most of the underground brine collection pumps currently used are or are similar to traditional deep well submersible pumps. In actual use, this type of pump is easy to accumulate salt on the surface of the brine flowing through, making the equipment unable to operate normally. After the equipment is processed or operated for about three days, a long fresh water immersion treatment is carried out. In some equipment, the motor was burned due to various factors in a relatively short period of time, which greatly increased the production cost. For this reason, people have carried out various treatments on the materials used in the underground brine collection pump and the surface of the brine flow, and the structure. Some improveme...

[0002] Most of the underground brine collection pumps currently used are or are similar to traditional deep well submersible pumps. In actual use, this type of pump is easy to accumulate salt on the surface of the brine flow, making the equipment unable to operate normally. After the equipment is processed or operated for about three days, a long fresh water immersion treatment is carried out

In some equipment, the motor was burned due to various factors in a relatively short period of time, which greatly increased the production cost. For this reason, people have carried out various treatments on the materials used in the underground brine collection pump and the surface of the brine flow, and the structure. Some improvements have been made, but none of them are ideal
