Description
Technical field
The utility model is related to boiler water circulatory system field, and in particular to a kind of auxiliary blade wheel structure of stove water pump.
Background technology
Stove water pump is the key equipment that high-rating generator factory forced circulation boiler normally runs, and up-thrust bearing holds in operation
Receive to overcome the axial thrust of tumbler weight, the upper surface for aiding in impeller is simultaneously the moving-coil of up-thrust bearing.In motor
The coolant in portion will also drive fluid flow inside by aiding in impeller, auxiliary impeller of the prior art, as shown in figure 1,
The diameter of upper and lower end face is identical, is all D, if so in the case where ensureing that upper surface can bear enough axial thrusts,
The diameter design of lower surface aids in the performance parameter of impeller to be restricted into identical with upper surface diameter, is met in motor
Performance parameter required for portion's flow of cooling water circulation, can so cause loss big, the low adverse effect of efficiency.
Utility model content
The utility model provides the auxiliary blade wheel structure of a kind of simple structure and the stove water pump of efficiency high.
To achieve these goals, the technical solution adopted in the utility model is：A kind of auxiliary blade wheel structure of stove water pump,
Pump case including vertical direction arrangement, the interior lumen of pump case is divided into the motor cavity and receiving main impeller for accommodating motor stator and rotor
Pump housing chamber, the main shaft for constituting rotor extends in pump housing chamber, and the lower end of main shaft is through the installation aided at the impeller axle heart
Hole is connected with auxiliary impeller, aids in the upper surface of impeller with diameter greater than lower surface diameter.
Requirement according to motor axial thrust come the diameter of the upper surface of Design assistant impeller, according to motor internal cooling water
Circulation and bearing lubrication requirement carry out the diameter of the lower surface of Design assistant impeller so that the upper and lower end face of auxiliary impeller works
In optimum state, so as to improve the operating efficiency of auxiliary impeller.
Brief description of the drawings
Fig. 1 is the sectional view for aiding in impeller in the prior art；
Fig. 2 is stereogram of the present utility model；
Fig. 3 is sectional view of the present utility model；
Fig. 4 is assembling schematic diagram of the utility model in stove water pump.
Specific embodiment
As shown in figure 3, a kind of auxiliary blade wheel structure of stove water pump, including the pump case 10 that vertical direction is arranged, pump case 10
Interior lumen is divided into the motor cavity 11 for accommodating motor stator and rotor and the pump housing chamber 12 for accommodating main impeller 30, constitutes rotor
Main shaft 20 extends in pump housing chamber 12, and the lower end of main shaft 20 passes through mounting hole and the auxiliary phase of impeller 40 at auxiliary impeller 40 axle center
Even, the upper surface of impeller 40 is aided in diameter greater than lower surface diameter.Auxiliary impeller 40 not only needs to overcome the axle of tumbler weight
To thrust, the upper and lower spacing of axial direction is realized to rotor, while aiding in the upper surface of impeller 40 as the dynamic of up-thrust bearing
Circle, is that motor internal cooling circulating water and bearing lubrication cooling water provide power, by the diameter design of lower surface into meeting motor
Internal cooling water circulation and bearing lubrication requirement, the diameter of upper surface meets requirement of the stove water pump to axial thrust, so upper and lower
End face is operated in optimum state respectively, so as to improve the operating efficiency of auxiliary impeller 40.
Preferably, refering to Fig. 2, Fig. 3, described auxiliary impeller 40 includes the sleeve pipe 41 coordinated with main shaft 20, sleeve pipe 41
Stage casing extends to form discoid body 42 laterally, and body 42 is coaxially disposed with sleeve pipe 41, the upper surface diameter D1 of body 42
More than lower surface diameter D2.Due to aiding in the axial thrust suffered by the upper surface of impeller 40 to be pushed away more than the axial direction suffered by lower surface
Power, so diameter D1 in upper surface is more than lower surface diameter D2.
As shown in figure 4, body 42 radially symmetrically offers multiple water dumping holes 421, set on the outer ring inwall of water dumping hole 421
There is chamfering.The quantity and pore size in water dumping hole 421 are set according to actual conditions, are allowed to meet traffic requirement；Chamfering plays water conservancy diversion
Effect, can guide the water from water dumping hole 421 out to walk upwards, the lift of cooling water is met lift demand.
