[0002] A centrifugal pump is a pump that transports liquids by the centrifugal force generated by the rotation of the impeller. It is generally an integrated structure consisting of a motor and a pump body.

[0003] For example, a chemical centrifugal pump disclosed in the utility model with authorization announcement number CN216044487U has sound insulation panels and sound-absorbing cotton simultaneously arranged inside two protective covers. Both the sound insulation panels and the sound-absorbing cotton can play a role in sound insulation and noise reduction, thereby reducing the decibels of sound transmitted outward from the pump body and the motor transmission part. The centrifugal pump needs to be connected to an external pipe when in use, but the existing connection method is mostly connected by bolts. Such a connection method not only takes a lot of time when connecting, but is also difficult to perform subsequent disassembly, which is time-consuming and labor-intensive. After long-term use, it may become difficult to disassemble due to rust in the structure. Utility Model Content
