Put on a hollow component, described component bottom is provided with the skull that can be opened, described adjusting screw adjustable side is exposed to
In component hollow cavity, described blade side contradicts adjusting screw, and opposite side contradicts resiliently deformable buffer body, described
Buffer body is contained in a groove of the component.
The technical program uses vertical structure, pump shaft to be vertically arranged with impeller, and wheel rotation connects more direct, vertical electricity
Machine is connected by shaft coupling with pump shaft, is driven more smooth；Change the elasticity of buffer body by screwing or unscrewing adjusting screw
, so as to realize adjusting the effect of blade angle, simple structure and rationally is reliable, and opens the i.e. operable tune of skull for deformation degree
Section screw, it is convenient.
The reinforcement worn by pump shaft is provided with below described Discharging bent-tube and pump shaft junction, is turned in Discharging bent-tube
Place's pump shaft is larger by the impact of current, and reinforcement is effectively played strengthens fixed effect, in addition the seam of pump shaft and Discharging bent-tube
Gap enters more sand in the case where current are more muddy, is more attached to the inwall of top bearing, then can influence pump shaft
Rotate, reinforcement is equal to and first stop once, effectively reduce the gap of the entrance pump shaft with Discharging bent-tube of sand.
The outer wall of described Discharging bent-tube is provided with pump shaft support, and pump shaft and pump shaft branch are communicated with described pump shaft support
The aqueduct in frame gap, can draw the current entered from pump shaft and Discharging bent-tube gap.
The oblique upper shed of described aqueduct.
Described described water inlet pipe to Discharging bent-tube forms pump chamber, and stator is provided with the pump chamber in rubber shaft bearing both sides
Body, plays water conservancy diversion effect.
The downward-sloping setting of described diffuser, water conservancy diversion effect is good.
The angle of inclination of described Discharging bent-tube is 25-35 degree, it is ensured that the smoothness of fixation Yu the water outlet of pump shaft.
A kind of axial-flow pump obtained by the utility model, simple structure is simultaneously reasonable, and it is operable adjusting screw to open skull,
Convenient, while realizing the angular adjustment of blade by the elastic deformation of buffer body, step-less adjustment, operation is smooth, reliable.
