Abstract
The utility model belongs to the field of water pumps and relates to a dive mixed-flow pump with an axial position capable of being adjusted and fixed. The dive mixed-flow pump with the axial position capable of being adjusted and fixed comprises a shaft, wherein one end of the shaft is connected with a motor shaft and the other end of the shaft is connected with an impeller. The impeller is fixed on the shaft through a positioning nut, a positioning screw and a locking nut, and the impeller is provided with an impeller room. A design mix section of the shaft is cylindrical and an axial adjusting section is arranged above the design mix section. The impeller is further provided with a straight hole which is matched with the shaft. According to the dive mixed-flow pump with the axial position capable of being adjusted and fixed, design requirements for a gap between the impeller and the impeller room are met due to the fact that the impeller is adopted to achieve up-and-down adjustment and fixation.

Background technique
Mixed flow pump belongs to blade water pump, is a kind of pump between centrifugal pump and axial-flow pump.With regard to its working principle, it is when relying on vane rotary, the end thrust of current generation and the double action of centrifugal force to be come work.From the direction of current turnover impeller, water flows into vertically, oblique outflow impeller, and therefore, mixed flow pump is also referred to as diagonal pumps.
The impeller of submersible mixed-flow pump and axle are with taper fit.Due to the precision problem of process equipment, the tapered hole precision of the tapering of axle and impeller is inaccurate, and the cooperation of two parts often goes wrong: impeller is contained in position on axle on the upper side the time, and the gap of impeller and blade wheel chamber surpasses the regulation requirement, and leaking increases, pump efficiency decline; Impeller is contained in position on axle on the lower side the time, and the gap of impeller and blade wheel chamber is too small or very close to each other, and friction or collision occur for the blade of impeller and blade wheel chamber, cause impeller or blade wheel chamber to damage, and the water pump operation resistance strengthens, and the water pump overburdening can't run well.
Therefore, urgent need a kind of axial position in pump technology field can be regulated fixing submersible mixed-flow pump.
Summary of the invention
The utility model provides a kind of axial position can regulate fixing submersible mixed-flow pump for the defective of existing submersible mixed-flow pump impeller.The technological scheme that the utility model adopts is as follows:
A kind of axial position can be regulated fixing submersible mixed-flow pump, comprising: axle, and an end connects motor shaft, and the other end connects impeller, and setscrew nut, positioning screwn and locking nut are fixed in this impeller on this axle; This impeller outer has blade wheel chamber; It is characterized in that,
The design cooperation position section of this axle is cylindrical, and the top of design cooperation position section arranges the axial adjustment section;
This impeller has straight hole, and this straight hole coordinates with this axle.
A kind of axial position as above can be regulated fixing submersible mixed-flow pump impeller, and wherein, this this axial adjustment section is 3 ~ 8 millimeters long.
A kind of axial position as above can be regulated fixing submersible mixed-flow pump impeller, and wherein, this axial adjustment section is 5 millimeters long.
The utility model carries out up-down adjustment on axle by impeller, then fixing, guarantees that the design gaps of impeller and blade wheel chamber meets designing requirement.

Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the axle of existing submersible mixed-flow pump and the structural representation of impeller.
Fig. 2 is that a kind of axial position of the utility model can be regulated the axle of fixing submersible mixed-flow pump and the structural representation of impeller.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The submersible mixed-flow pump mainly is made of suction pipe, Sealing, axle, impeller, blade wheel chamber, because main structure is prior art, does not give unnecessary details herein.Fig. 1 shows the axle of existing submersible mixed-flow pump and the detailed construction of impeller.
Axle 1, one end connects motor shaft, and the other end connects impeller 2, and the rotation of motor is passed to impeller 2, axle 1 and impeller 2 taper fit; Setscrew nut 3, positioning screwn 4 and locking nut 5 are fixed in impeller 2 on the design attitude of axle 1.
Due to the machining accuracy problem, the tapered hole precision of the tapering of axle 1 and impeller 2 is inaccurate, and the cooperation of axle 1 and impeller 2 often goes wrong: impeller 2 is contained in position on axle 1 on the upper side the time, and impeller 2 surpasses the regulation requirement with the gap of blade wheel chamber 6, leaking increases, and pump efficiency descends; Impeller 2 is contained in position on axle 1 on the lower side the time, impeller 2 is too small or very close to each other with the gap of blade wheel chamber 6, and friction or collision occur for the blade of impeller 2 and blade wheel chamber 6, causes impeller 2 or blade wheel chamber 6 to damage, the water pump operation resistance strengthens, and the water pump overburdening can't run well.
Fig. 2 shows a kind of axial position of the utility model can regulate the axle of fixing submersible mixed-flow pump and the detailed construction of impeller, comprising:
Axle 1, one end connects motor shaft, and the other end connects impeller 2, and the rotation of motor is passed to impeller 2; The design cooperation position section 7 of axle 1 is cylindrical, and the long axial adjustment section 8 of 3 ~ 8mm is set above the design cooperation position;
Setscrew nut 3, positioning screwn 4 and locking nut 5 are fixed in impeller 2 on axle 1.
The optimum length of this axial adjustment section 8 is 5mm.
The advantage of this structure is: carry out up-down adjustment on axle by impeller, and then fixing, guarantee that the design gaps of impeller and blade wheel chamber meets designing requirement.
