Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pumps, in particular to a novel centrifugal pump terminal seat structure. Background Art

[0002] In order to facilitate installation by installers or maintenance by maintenance personnel, a terminal block structure is provided on the centrifugal pump housing. The terminal block structure includes a terminal block body integrally provided with the centrifugal pump housing. The terminal block body has an opening, and the opening is matched with a terminal block cover.

[0003] like Figure 1 As shown, the existing terminal block body 2 is usually provided with a wiring port 3 connected to the inner side of the centrifugal pump casing 1, through which the internal wiring is connected to the capacitor and the external wiring. However, since the terminal block body is integrally provided on the centrifugal pump casing, the capacitor installed in the terminal block body will be close to the centrifugal pump casing, which causes the vibration of the centrifugal pump and the heat of the body to be directly transferred to the capacitor, resulting in a short life of the capacitor, and the position of the capacitor is prone to movement, resulting in poor wiring, which poses a safety hazard to the operation of the centrifugal pump. At the same time, the wiring in the existing terminal block body is relatively messy, which causes troubles for maintenance and disassembly. Utility Model Content
