Abstract
The invention discloses a thin-wall-long-shaft-low-noise transmission mechanism for pedestal pumps, which includes a stainless steel pipe, a first bushing and a second bushing, a pump body, an impeller and a motor, the motor is arranged above the stainless steel pipe, the first and second bushings are embedded at first and second ends of the stainless steel pipe respectively, the impeller includes an impeller hub shaft, the motor includes a motor shaft, the impeller hub shaft passed through the pump body and connected to the first bushing which is embedded in the first end of the stainless steel pipe. Through the above solution, the machining precision of the thin wall stainless steel pipe is higher than that of a solid metal shaft and a plastic shaft, the strength is higher than that of a plastic shaft, and the noise is reduced when the pump is working.
