Description

Technical Field

[0001] The utility model relates to the technical field of pump impellers, in particular to a pump impeller with easy-to-disassemble blades. Background Art

[0002] The pump impeller is a core component of the pump. Its primary function is to convert mechanical energy provided by a motor or other power source into kinetic energy of the liquid. The impeller's design and shape have a decisive impact on the pump's performance, including flow rate, head, and efficiency. However, in actual use, existing technologies require the impeller to be replaced after prolonged operation or when the pump body is damaged. However, in existing pump designs, the impeller and pump body are mostly integrated, making impeller replacement a complex and cumbersome process. When replacing an impeller, the entire pump body must be replaced, resulting in a complex operation.

[0003] According to the description of a spiral centrifugal impeller for a spiral centrifugal pump that is easy to replace (authorization announcement number: CN219262709U) published on the patent website, the spiral centrifugal impeller for a spiral centrifugal pump that is easy to replace includes "device body, base plate, motor" and the like for replacement work.

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] The spiral centrifugal impeller of the easily replaceable spiral centrifugal pump is replaced by using the device body, base plate, motor, etc. During use, the centrifugal impeller is replaced by unscrewing the bolts on the fixed plate, taking out the pump shaft, and replacing the pump shaft and impeller as a whole. It is impossible to replace the impeller separately, resulting in a waste of resources. Therefore, it is necessary to improve the centrifugal impeller. Utility Model Content

[0017] The pump impeller with easy-to-remove blades can, through the provided sealing mechanism, achieve a sealing effect between the fixing sleeve and the pump casing when the impeller body is inserted into the connecting shaft and drives the fixing sleeve to slide through the inside of the pump casing to be connected to the outside of the connecting shaft. Therefore, the sealing effect of the pump casing when in use is ensured, and the sealing sleeve can be kept in a stable state under the action of the second spring. When the impeller body needs to be taken out, the limit rod is driven to move by the pull ring, and the pull ring drives the sealing sleeve to move through the fixing frame and squeezes the second spring, so that the sealing sleeve can be moved away from the periphery of the fixing sleeve, making it easy to take out the impeller body for disassembly.
