Embodiment

[0020] Example: Flow 200m 3 The amount of fresh water injected by the pump per hour should be less than 200*20%=40m 3 / h

[0021] Fresh water should be injected when the density of brine output by the pump is kept less than 1.2:

[0022] ρ 混 = m 总 / V 总 =(m 卤 +m 水 ) / (V 卤 +V 水 )………1

[0023] V 卤 +V 水 =200………2

[0024] Let ρ 混 =1.2(g / L)

[0025] Substitute 2 into 1 to get V 水 =26(m 3 )

[0026] That is, the flow rate is 200m 3 / h pump should inject fresh water not less than 26m 3 / h, not more than 40m 3 / h

[0027] ρ 混 ——The density of brine output by the pump

[0028] m 总 ——The total mass of brine output by the pump

[0029] m 水 ——The quality of fresh water contained in the brine output by the pump

[0030] V 总 ——The total volume of brine output by the pump

[0031] V 水 ——The volume of fresh water contained in the brine output by the water pump

[0032] The working pressure of tap water is 3 atmospheres, or 30 meters. Flow 200m 3 / h of the pump, t...

Abstract

The invention discloses a high-concentration bittern immersible pump and an application method. The high-concentration bittern immersible pump is characterized in that according to the structure, a thin flange is placed on an upper connecting flange notch face to form a ring groove, and clean water injection pipes are symmetrically arranged between an upper connecting flange and the thin flange in the radial direction; and radial openings of four stand column pipes face the circle center, the upper ends are welded to the bottom edges of corresponding holes of the thin flange, the lower ends are welded to a middle flange, a large hole of the thin flange communicates with inner cavities of the stand column pipes and is located in an upper connecting flange groove, a plurality of evenly-distributed water outlets are circularly formed in an upper connecting flange, a fresh water channel is jointly formed, and after fresh water shaft flushing, the fresh water and operating liquid are mixed and enter an upper shell at the position of an impeller. According to the application method, when the fresh water injection amount proportion is 14.35% under the condition that the flow of tap water is 1.2 m / s, the fresh water inlet size and pump specification are set according to the proportion, and the inner diameter of the water inlet pipe is set to be 65 mm for a pump with the flow being 200 m<3> / h. The high-concentration bittern immersible pump and the application method have the beneficial effects that operation is conducted under bittern close to saturation concentration, and frequent pump body replacing, flushing and maintaining are needed.

Description

technical field [0001] The invention relates to the manufacture of a submersible pump, a submersible pump used in crystalline brine with a density of 1.23. Background technique [0002] In the crystalline brine with a density of 1.23, soon after the operation of the submersible pump, severe potassium salt crystals filled the pump and solidified parts, and the pump could not work. The general pump body structure of submersible pumps is: the water inlet shell is a casting, the pump shaft of the company is installed in the center cavity, the upper and lower flanges are supported by four solid ribs, the shell is installed on the upper flange, the motor is connected to the lower flange, and the brine flows from the supporting ribs. Space enters the upper flange bore, into the impeller. Due to the high concentration of brine, crystals soon filled all parts of the pump body, and the stuck parts could not work. Contents of the invention [0003] The purpose of the present invent...
