Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pumps, in particular to a centrifugal pump anti-blocking mechanism and a centrifugal pump. Background Art

[0002] A centrifugal pump is a type of pump that uses centrifugal force to transport liquids. Its basic working principle is that the rotating impeller in the pump body accelerates the liquid, causing it to generate centrifugal force, pushing the liquid from the center of the pump to the periphery, thereby achieving liquid transportation.

[0003] When a centrifugal pump is used to transport liquid, the liquid is input into the interior of the centrifugal pump through the water inlet of the centrifugal pump. When the liquid enters, the liquid carries particulate impurities and the like into the pump body, thereby clogging the pump body. In order to solve the problem of particulate matter entering, a filter is installed between the water inlet of the centrifugal pump and the water inlet pipe to filter the particulate matter. After long-term use, the filter needs to be disassembled and cleaned due to clogging by particulate matter. When cleaning the filter, the water inlet pipe needs to be removed from the centrifugal pump, and the filter arranged between the water inlet pipe and the centrifugal pump needs to be disassembled and cleaned, which makes it difficult to clean the anti-blocking mechanism and increases the cleaning time of the staff.
