Abstract
The utility model discloses a piping centrifugal pump which comprises a motor and a pump body. The motor is arranged on the pump body and shares the same end cover with the pump body. A water blocking ring is arranged on a position where the motor and the pump body are connected. A shaft of the motor extends into a cavity of the pump body. The shaft is provided with an impeller. Pyroceram is used for mechanical sealing on a position where the shaft and the pump body are sealed. According to the piping centrifugal pump, the motor and the pump body share the same end cover, an axial size is shortened, structure is simple, a mounting bottom plate and a bolt hole are arranged on the bottom of the pump body, so that a whole machine set can be mounted firmly conveniently. And the pyroceram is used for mechanical sealing on a position where the shaft and the pump body are sealed, high acid-base resistant performance, abrasion resistant performance and the like are achieved, thermal shock performance is good, a manufacturing method is easy, cost is low, and production and application are convenient.
