Description

Technical Field

[0001] The utility model relates to the technical field of impellers for submersible pumps, in particular to an impeller for submersible pumps with an anti-clogging effect. Background Art

[0002] Submersible pumps are used in various environments due to their small size and light weight, especially in outdoor waters. There are various impurities on the bottom of the water, such as branches, gravel, and domestic garbage. In order to cope with complex water conditions, traditional submersible pumps usually add an interception filter at the water inlet to reduce the failure of the submersible pump by blocking foreign objects.

[0003] When the existing impeller of a submersible pump is put into water for use, the gap between the blades is too small. When the impeller is working, the mud in the water will cause the impeller to become dirty and blocked, and at the same time increase the burden on the motor, causing the motor to overheat and be damaged, thereby causing the risk of leakage.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an impeller for a submersible pump with an anti-clogging effect is proposed. Utility Model Content
