Description

Technical Field

[0001] The utility model relates to the field of impellers, in particular to a detection device capable of adapting to impellers of different lengths. Background Art

[0002] In the prior art, during the processing and production of pumps, the impeller of the pump is fixed on the pump shaft; however, the impeller may slip during rotation. Since the shaft body of the impeller shaft is directly connected to the impeller, when slipping occurs, the impeller wears the shaft body greatly, reducing the service life of the impeller shaft.

[0003] The pump shaft and the impeller are connected by a threaded connection. To ensure concentricity, a small clearance fit is used at the two end points where the pump shaft and the impeller shaft are connected; the same is true during processing, ensuring concentricity and thickening the impeller shaft.

[0004] Due to the limitation of the impeller shape, when the existing concentricity detection device detects the concentricity of the impeller shaft and the pump shaft, impeller shafts of different lengths will cause the device for restricting the position of the impeller shaft to be unable to adapt to the length of the impeller, resulting in excessive extension length of the end face of the impeller and unstable rotation of the impeller.
