Deep-well pump and impeller transmission structure

Abstract

According to the impeller transmission structure, the anti-wear structure is arranged in the guide vane, meanwhile, the rear-end impeller is supported, radial swing of the pump shaft is supported, the anti-wear structure is arranged in the mode that the first supporting part is close to the rear-end impeller, and in the water pumping process, the impeller shaft end of the rear-end impeller abuts against the first supporting part; and the supporting stability of the rear-end impeller in the water pumping process is ensured. The second supporting part supports the pump shaft in the radial direction, radial swing of the pump shaft is reduced, radial abrasion of the pump shaft is reduced, the rear-end impeller and the pump shaft are independently supported through the first supporting part and the second supporting part, the supporting stability of the rear-end impeller and the pump shaft is guaranteed, and meanwhile the water pumping safety of the deep-well pump working for a long time is guaranteed. The invention further provides a deep-well pump.

Description

technical field [0001] The invention relates to the technical field of deep well pumps, in particular to a deep well pump and an impeller transmission structure. Background technique [0002] In the existing guide seat structure of the deep well pump, the impeller is used to pump water between adjacent guide seats, the impeller is driven to rotate synchronously by the impeller shaft, and the guide body is arranged in the guide seat to cooperate with the impeller pump water. [0003] When the guide body and the impeller are arranged, the guide body is fixed in the guide seat, the pump water end of the impeller is matched with the guide body to pump water, the shaft end of the impeller extends into the shaft hole of the upper guide body, and the shaft of the guide body The holes are usually arranged with O-type friction plates to support the shaft end of the impeller. However, after the impeller shaft works for a long time, its rotation center will be offset, resulting in con...

AI Technical Summary

Problems solved by technology

However, after the impeller shaft has been working for a long time, its rotation center will shift, resulting in contact wear between the impeller shaft and the O-shaped friction plate. In severe cases, there will be a problem of friction and cutting between the O-shaped friction plate and the impeller shaft, which will affect the working stability of the deep well pump.
