[0029] As described in the background art, the pH value in the brine has a great influence on the guide shell and the impeller. Therefore, the material of the guide shell and the impeller is relatively important.

[0030] In order to solve this technical problem, the present invention provides a novel guide shell and impeller, which are applied to a submersible brine pump.

The guide shell and the impeller are made of cast iron, cast copper, nylon plastic, and stainless steel, and guide shells and impellers of different materials can be selected according to the pH value in the brine.

[0035] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] Embodiment 1:

[0037] Please refer to Figure 1 - Figure 6 , a new guide shell and impeller, comprising:

[0038] The guide shell body includes an outer shell 1, end plates 2 are arranged at both ends of the outer shell 1, reinforcement members 5 are fixedly connected to the outer side of the outer shell 1 and between the end plates 2, and the number of reinforcement members 5 is several, a center piece 3 is arranged on the inner side of the outer shell 1, and guide plates 4 are arranged on the surrounding side of the center piece 3, and the number of guide plates 4 is multiple, one end of the multiple guide plates 4 is fixedly connected to the center piece 3, and the other end of the multiple guide plates 4 is fixedly connected to the inner wall of the outer shell 1; further, the material of the guide shell body is any one of cast iron, cast copper, nylon plastic, and stainless steel.

[0039] The impeller body includes a rotating sleeve 6, a mounting through hole 8 is provided in the middle of the rotating sleeve 6 for connecting with the driving shaft, and blades 7 are fixedly connected to the peripheral side of the rotating sleeve 6, and the number of blades 7 is multiple. Further, the material of the impeller body is any one of cast copper, stainless steel, and nylon plastic.

[0040] Generally, a cast iron guide shell is chosen for brine. The guide shell is a static fluid, and the impeller rotates to drive the moving fluid. Generally, stainless steel impellers, copper impellers, and nylon plastic impellers are all acceptable. However, when encountering a lot of quicksand and sludge, the wear resistance of the plastic impeller is not as good as that of stainless steel and copper impellers.

[0041] Generally, acid-base brine with pH≤6 is suitable for cast copper, stainless steel, nylon plastic flow guides, and impellers of various materials. Cast iron flow guides will be completely corroded if not used for a few days to 3 months. Strong acid-base brine with chloride ions with pH≥8 is generally recommended to use nylon plastic flow guides and nylon plastic impellers, which will not corrode. The durability of cast copper is average, and stainless steel can be corroded in 2 to 3 days.

[0042] Embodiment 2:

[0043] The novel guide shell and impeller provided in Example 1 are further optimized. Specifically, Figure 3 As shown, the guide plate 4 includes a plate body 41, the plate body 41 is a straight plate, and the number of the plate bodies 41 is 4-8.

[0044] Embodiment 3:

[0045] The novel guide shell and impeller provided in Example 1 are further optimized. Specifically, Figure 4 As shown, the guide plate 4 includes a second plate body 42, the second plate body 42 is an arc plate, and the number of the second plate bodies 42 is 4-8.

[0046] Embodiment 4:

[0047] The new guide casing and impeller provided in Example 1 are further optimized. Specifically, the number of blades 7 is 4-8.
