Description

Technical Field

[0001] This utility model relates to the field of submersible pump technology, and specifically to a submersible pump guide shell. Background Technology

[0002] Submersible pumps are essential water lifting equipment. During operation, the entire unit is submerged in water to extract groundwater to the surface. They are widely used for domestic water extraction, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship ballast adjustment, and fountain landscaping. The submersible pump's guide vane, also known as a space guide vane, primarily functions to change the flow direction of the liquid exiting the impeller outlet and transport it to the next stage impeller inlet or the pump outlet.

[0003] However, the existing submersible pump guide casing does not have a filter device for sand and gravel, which makes it easy for sand and gravel to enter the submersible pump guide casing, thereby affecting the normal operation of the impeller inside the submersible pump guide casing.
