Abstract
The invention relates to an impeller locating device for a double-suction axially-split pump. The impeller locating device comprises two impeller nuts, and after an impeller is arranged on a shaft of the double-suction axially-split pump in a sleeved mode, the two ends of the impeller are located by the impeller nuts in a locking mode. The positions, on the shaft, of the impeller can be adjusted through the impeller nuts at the two ends of the impeller. Compared with the prior art, the impeller locating device has the advantages of being high in reliability, convenient to disassemble and assemble, rapid and convenient to maintain and repair and the like.
Description
Technical field
The present invention relates to a kind of Double entry middle-opening pump correlation technique, especially relate to a kind of impeller positioning device for Double entry middle-opening pump.
Background technique
The blade wheel positioning structure of existing Double entry middle-opening pump generally has three kinds:
The first is that axle sleeve is equipped with at the two ends of impeller hub, and the other end of axle sleeve is close to bearing inner race end face, and bearing positioning instant has been realized the location of impeller.Although this structure is closed shaft seal.But because axle sleeve is longer, assembling, when dismounting is very difficult and due to processing, assembly error often causes impeller outlet center and pump housing runner center to be difficult to align affects hydraulic performance.
The second is at the dress impeller hub place of axle fluting, packs circlip in groove into, with circlip, impeller is located.This structure can only be for horizontal type structure, when for vertical structure, because impeller deadweight cannot be born bullet part packing ring.
The third is that impeller hub one end is located by step on axle, the other end nut locking, although vertical, the sleeping two kinds of structures of this localization method all can be used, but owing to there being step, the material of axle is wasted, and affects hydraulic performance because processing and assembling error often causes impeller outlet center and pump housing runner center to be difficult to align.
Summary of the invention
Object of the present invention be exactly in order to overcome the defect that above-mentioned prior art exists, provide that a kind of reliability is high, easy accessibility, maintaining be easily for the impeller positioning device of Double entry middle-opening pump.
Object of the present invention can be achieved through the following technical solutions:
An impeller positioning device for Double entry middle-opening pump, is characterized in that, comprises two impeller nuts, and after described impeller set is located on the axle of pump, two ends are by impeller nut lock in place; The position of impeller on axle can be adjusted by the impeller nut at impeller two ends.
The axle of described pump is useful on the screw thread that impeller nut is used at impeller hub place.
On described impeller nut cylindrical, be uniformly distributed a plurality of screws, in each screw, be equipped with for the fixing fastening screw trip bolt of impeller nut.
Described screw is three.
Compared with prior art, the present invention has the following advantages:
Because impeller two ends are located and locked by impeller nut, thereby facilitated the adjustment of impeller outlet center and pump housing runner centering, guaranteed the efficiency of water pump, during simultaneously for vertical structure, can not locate the unreliable problem that occurs that impeller sinks because of impeller yet, owing to having removed axle sleeve, thereby the mounting or dismounting of impeller are very convenient, greatly facilitate user to the maintenance of pump, maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the main TV structure schematic diagram of impeller nut of the present invention;
Fig. 3 is impeller nut plan structure schematic diagram of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As Figure 1-3, a kind of impeller positioning device for Double entry middle-opening pump, comprises two impeller nuts 1, and after described impeller 2 is set on the axle 4 of pump, two ends are by impeller nut 1 lock in place; The position of impeller 2 on axle 4 can be adjusted by the impeller nut 1 at impeller 2 two ends.
The axle 4 of described pump is useful on the screw thread that impeller nut 1 is used at impeller hub place.On described impeller nut 1 cylindrical, be uniformly distributed three screws, in each screw, be equipped with for the fixing fastening screw trip bolt 3 of impeller nut.
Installation process is as follows:
On axle 4, pack impeller 2 into, by on the screw thread at the impeller hub place of two impeller nuts, 1 screw-in axle, be close to impeller hub end face, the position of impeller on axle can be easily impeller nut 1 by impeller two ends go to adjust, on impeller nut 1 cylindrical, there are three uniform screws, in screw, are screwed into three fastening screw trip bolts 3 fixing as impeller nut.
Claims (4)
1. for an impeller positioning device for Double entry middle-opening pump, it is characterized in that, comprise two impeller nuts, after described impeller set is located on the axle of pump, two ends are by impeller nut lock in place; The position of impeller on axle can be adjusted by the impeller nut at impeller two ends.
2. a kind of impeller positioning device for Double entry middle-opening pump according to claim 1, is characterized in that, the axle of described pump is useful on the screw thread that impeller nut is used at impeller hub place.
