Abstract
The invention relates to the technical field of water pumps, in particular to a vertical centrifugal pump. According to the technical scheme, the vertical centrifugal pump comprises a motor and a pump body. A water inlet pipe is arranged on one side of the pump body, and a water outlet pipe is arranged on the other side of the pump body. A rotating shaft of the motor extends into a pump cavity of the pump body. The rotating shaft of the motor is provided with an impeller located in the pump cavity. At least one set of vibration absorption structures is arranged between the motor and the pump body. The vibration absorption structures are arranged in an outer space between a motor base and the pump body. Each vibration absorption structure comprises a fixing rod connected with the motor base and a dynamic vibration absorption device installed on the fixing rod. The vertical centrifugal pump has the beneficial effects that at least one set of vibration absorption structures is arranged between the motor and the pump body and provided with the dynamic vibration absorption device, the dynamic vibration absorption devices can absorb vibration produced when the centrifugal pump works, the failure rate of parts in the pump cavity is reduced, and on the whole, the service life of the centrifugal pump is prolonged.
Description
Technical field
