Description

Technical Field

[0001] The utility model relates to the technical field of submersible sewage pumps, in particular to an oil-cooled submersible sewage pump. Background Art

[0002] An oil-cooled submersible sewage pump is a pumping device that uses a cooling liquid to form a circulation channel inside the pump body for water cooling. When using the submersible sewage pump, the pump body is placed inside the sewage, and the motor drives the impeller to rotate to generate centrifugal force to pump water out of the sewer. The rotation of the impeller creates a pressure difference, causing the sewage to be sucked in and discharged.

[0003] The inventors found in their daily work that the submersible sewage pump still has at least the following problems: when using the submersible sewage pump, the pump body is placed inside the sewage, and the impeller is driven by the motor to rotate to generate centrifugal force to pump water out of the sewer. The rotation of the impeller generates a pressure difference, so that the sewage is sucked in and discharged. However, in actual use, when there are small stones in the sewage, the small stones will directly hit the surface of the impeller. Long-term use will cause damage to the impeller, which will affect the service life of the submersible sewage pump to a certain extent. Utility Model Content
