Description

Technical Field

[0001] The utility model relates to the technical field of vertical centrifugal pumps, in particular to a vertical centrifugal pump with an auxiliary supporting structure. Background Art

[0002] A vertical centrifugal pump is a water pump that uses centrifugal force to achieve continuous water delivery. It is divided into six parts: impeller, pump body, pump shaft, bearing, sealing ring, and stuffing box. Due to the special structure of the vertical centrifugal pump, it is necessary to adopt an upright installation method during use. The lower end of the vertical centrifugal pump is fixed with bolts during installation. Since the motor of the vertical centrifugal pump is located at the upper end, the motor will vibrate when it is working. If the vertical centrifugal pump runs for a long time, it may cause the bolts at the bottom to loosen. In order to prevent the bolts from loosening, the outside of the vertical centrifugal pump is supported by shock absorption. Therefore, a vertical centrifugal pump with an auxiliary support structure has appeared.

[0003] With respect to the disclosed technology, in the existing vertical centrifugal pump with an auxiliary support structure, after the centrifugal pump is installed, the heat dissipation port on the top will be set upward. However, when the centrifugal pump is stationary, if the centrifugal pump is placed outside for a long time, external dust will enter the heat dissipation structure of the centrifugal pump through the heat dissipation port. The dust accumulates inside the heat dissipation structure, which may affect the normal operation of the heat dissipation structure, the heat dissipation effect of the centrifugal pump is affected, and thus the service life of the vertical centrifugal pump is also affected.

[0004] For this purpose, a vertical centrifugal pump with an auxiliary supporting structure is proposed. Utility Model Content
