Beschreibung
Zusammenfassung:	The utility model belongs to the technical field of centrifugal pumps, and particularly relates to an automatic centering buffer device of a centrifugal pump, which comprises a bearing arranged at the end of a rotating shaft and a mounting seat arranged on the inner side wall of a pump casing, the mounting seat is arranged on one side wall of the pump casing facing the rotating shaft, and the bearing is arranged at one end of the rotating shaft facing the pump casing. A mounting cavity is formed in the mounting seat, the side, facing the rotating shaft, of the mounting seat is open, and an elastic supporting piece is arranged on the outer wall of the bearing and supported on the inner wall of the mounting cavity. The elastic supporting pieces are supported on the inner wall of the mounting cavity, so that the rotating shaft is supported in the middle of the inner cavity of the mounting cavity, and as the weight of the rotating shaft of the centrifugal pump is small, the influence caused by the gravity is igno
