Above-mentioned flexible shaft water pump preferred version, pump shaft end has internal square hole, and flexible axle end is quadrangular structure, and is plugged to one with pump shaft.
Above-mentioned flexible shaft water pump preferred version, the pipe shaft corner of the Discharging bent-tube formation connecting tube that stretches out, has attachment hole on connecting tube, and connecting tube axis is with to cross axle assembly axis consistent.
Above-mentioned flexible shaft water pump preferred version, pump housing assembly comprises pump shaft, diffuser and impeller, and impeller is arranged on pump shaft and is arranged in diffuser, and diffuser is connected with water outlet flange, and diffuser is arranged on pump shaft.
Above-mentioned flexible shaft water pump preferred version, diffuser intra vane is arranged in the shape of a spiral.
Above-mentioned flexible shaft water pump preferred version, power transmission unit comprises pto＝power take-off, and pto＝power take-off one end is provided with belt pulley, and the pto＝power take-off the other end is connected with flexible axle.
Above-mentioned flexible shaft water pump preferred version, crosses axle assembly and comprised axle housing, crosses axle housing and is connected with Discharging bent-tube, crosses axle housing and is connected with pto＝power take-off by two bearings that set within it.
The beneficial effects of the utility model:
Because the cooling effect of fluid makes the temperature that flexible axle and flexible pipe produce at work make flexible axle because water band is full of rear automatically stretching by fluid again in low-temperature condition all the time, flexible pipe is in straight state, thereby the spoilage of flexible axle and flexible pipe is reduced greatly; Flexible axle and pump shaft are plugged to one, need not flexible axle be pulled out by force from flexible pipe with jackscrew, to fix afterwards again, install, easy to operate.Lift is high, flow is large and energy consumption is little.
