Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the premise of creative work
Lower obtained all other embodiment, belongs to the scope of the utility model protection.
Such as Fig. 1, the utility model embodiment provides in a kind of novel impeller water pump, including the pump housing 1, the pump housing 1 and is provided with leaf
Wheel shaft 2 and impeller, one end of impeller axle 2 are connected with motor 3, and impeller sleeve 4 is fixedly mounted by key in the other end.
The pump housing 1, which is provided with water inlet 11 and delivery port 12, water inlet 11, is provided with the first hydraulic pressure sensor 13, delivery port 12
Place is provided with the second hydraulic pressure sensor 14, and the first hydraulic pressure sensor 13, the second hydraulic pressure sensor 14 connect PLC, PLC respectively
Controller is connected with motor 3, and the He of 1 water inlet of the pump housing 11 is obtained by the first hydraulic pressure sensor 13 and the second hydraulic pressure sensor 14
Pressure at delivery port 12, PLC is handled and analyzed to data, judges whether impeller damages from pressure difference value,
And the operation of controlled motor 3, the degree of accuracy is higher.
Impeller sleeve 4 is provided with adjustment step 41, and adjustment step 41 has the First terrace that the housing with the pump housing 1 coordinates
With second step face, First terrace is vertical with second step face, and adjustment step 41 is integrally formed with impeller sleeve 4, adjustment platform
Rank 41 or two grades of connected steps, further to improve the installation accuracy of impeller sleeve 4.
Dovetail groove 42 is uniformly distributed on impeller sleeve 4, impeller includes linear leaf 5 and short blade 6, linear leaf 5 and short blade 6
Afterbody be provided with the boss that matches with dovetail groove 42, it is ensured that the tight ness rating inlayed of blade and impeller sleeve 4 and impeller
Intensity, if while a certain blade damage, it is only necessary to change new blade.Short blade 6 be located at adjacent linear leaf 5 it
Between, short blade 6 is the streamline shape that wide cut is distorted, and linear leaf 5 meets close to the streamline shape that the side of boss is that wide cut is distorted
The flow regime of current, opposite side is provided with bending section 51, and bending section 51 is identical with the direction of twist of short blade 6, and curvature is more than short
