Description

Efficient high temperature resistant centrifugal pump structure Technical Field The utility model relates to the technical field of centrifugal pumps, in particular to a high-efficiency high-temperature-resistant centrifugal pump structure. Background A centrifugal pump is a machine that uses rotation of a rotating impeller to generate centrifugal force to convey fluid. When the conventional centrifugal pump is designed and installed, the position of the centrifugal pump and the directions of an inlet and an outlet on a pump shell can be designed according to the arrangement position of connecting pipelines. However, during use of the centrifugal pump, the position of the connecting pipe connected to the centrifugal pump is often changed, which results in that the position of the centrifugal pump outlet does not correspond to the position of the connecting pipe, and the connection between the connecting pipe and the pump body outlet is affected. The utility model discloses a centrifugal pump in the patent application with the prior art publication number of CN 211852277U, wherein a support ring is arranged on a support, a clamping ring and a pump shell are matched to clamp the support ring, after the clamping ring and the pump shell are loosened, the pump shell and the clamping ring can be simultaneously rotated on the support ring to enable the position of a liquid outlet to correspond to a connecting pipeline, after the adjustment is finished, the pump shell and the clamping ring are fixed, the clamping ring can be clamped to enable the position of the pump shell to be fixed, so that after the connecting position of the connecting pipeline corresponding to the liquid outlet is changed, the installation position of the support of the centrifugal pump is not required to be changed, and the position of the liquid outlet can be adjusted only by adjusting the rotation angles of the pump shell and the clamping ring on the support ring, thereby being convenient for connecting the centrifugal pump and the connecting pipeline. However, in the prior art, the structure of the device is complex, the manufacturing cost is high, and the later maintenance is high, so that the practicability of the device is low.
