Abstract
The utility model discloses a locked impeller structure of a water ring pump. The locked impeller structure comprises an impeller body (1) and an impeller locking component (2), wherein the impeller body (11) is provided with the axial internal thread hole (11), and the impeller locking component (2) is threaded and formed of a steel wire in a winding manner, and is screwed in the internal thread hole (11) with a certain pretension force. A pump shaft is mounted in the internal thread hole by the impeller locking component, and equivalently, a stressed elastic pad is arranged between each two pitches of the threaded impeller locking component connected with the thread of the pump shaft, so that the impeller body and the pump shaft are locked with each other effectively. Accordingly, when the pump shaft of the water ring pump rotates reversely, loosing between the pump shaft and the impeller can be avoided, the impeller can be prevented from falling off the pump shaft, and stability and reliability in running of the water ring pump are improved.
Description
Technical field
The utility model relates to the water ring pump technical field, relates in particular to a kind of locking blade wheel structure of water ring pump, and the water ring pump of using this locking blade wheel structure.
Background technique
Water ring pump comprises pump shaft and impeller, and axial interior threaded hole is set on impeller, and outside thread is set on the pump shaft, pump shaft is screwed in the interior threaded hole of impeller to accomplish both assemblings.Water ring pump is when running well, and pump shaft and impeller remain stable power transmission; But, when the counter-rotating of the pump shaft of water ring pump, can cause be threaded between pump shaft and the impeller loosening, even impeller possibly come off from pump shaft, thereby influence the normal operation of water ring pump, there is potential potential safety hazard.
The model utility content
To the problem that existing technology exists, the utility model provides a kind of locking blade wheel structure of water ring pump, can prevent becoming flexible between impeller and the pump shaft.The utility model has also proposed a kind of water ring pump of this locking blade wheel structure of application.
For reaching this purpose, the utility model adopts following technological scheme:
The utility model provides a kind of locking blade wheel structure of water ring pump; Comprise impeller body; Axial interior threaded hole is set on impeller body, comprises also by the steel wire coiling forming and being screw-shaped impeller anti-loose spare that impeller anti-loose spare is spun in the interior threaded hole with certain pre-tensioning.
Preferably, under free state, the external diameter of impeller anti-loose spare is greater than the internal diameter of interior threaded hole, so that impeller anti-loose spare forms certain pre-tensioning and is spun in the interior threaded hole when being fit into interior threaded hole.
Preferably, the axial length of impeller anti-loose spare is less than or equal to the axial length of interior threaded hole.
Preferably, said impeller anti-loose spare is formed by the coiling of stainless steel steel wire.
The utility model has also proposed a kind of water ring pump, comprises pump shaft and impeller, and said impeller is above-mentioned locking blade wheel structure, and pump shaft is installed in the interior threaded hole through impeller anti-loose spare.
Based on disclosing of above technological scheme, the utility model possesses following beneficial effect:
The locking blade wheel structure that the utility model proposes; Comprise by the steel wire coiling and form and be screw-shaped impeller anti-loose spare; Impeller anti-loose spare is spun on certain pre-tensioning in the interior threaded hole of impeller body, and like this, pump shaft is installed in the interior threaded hole through impeller anti-loose spare; Be between screw-shaped impeller anti-loose spare and each pitch that the pump shaft screw thread is connected and be equivalent to be provided with a pressurized bullet pad, thereby with impeller body and the firm locking of pump shaft.Through above-mentioned setting, when the pump shaft counter-rotating of water ring pump, can avoid becoming flexible between pump shaft and the impeller, prevent that impeller from coming off from pump shaft, improved the stability and the reliability of water ring pump work.
In the optimal technical scheme of the utility model, under free state, the external diameter of impeller anti-loose spare is greater than the internal diameter of interior threaded hole; When being fit into interior threaded hole, thereby the external diameter of impeller anti-release member diminishes and forms certain pre-tensioning under the effect of external force, and is spun in the interior threaded hole; Like this; Be screw-shaped impeller anti-loose spare and can be securely fixed in the interior threaded hole, avoid from interior threaded hole, coming off, further improved the effect that impeller loosens because of the counter-rotating of pump shaft.
Description of drawings
Fig. 1 is the structural representation of the locking blade wheel structure of a kind of water ring pump of the utility model proposition.
Fig. 2 is for being the structural representation of screw-shaped impeller anti-loose spare among this Fig. 1.
Embodiment
Further specify the technological scheme of the utility model below in conjunction with accompanying drawing and through embodiment:
As shown in Figure 1, the structural representation of the locking blade wheel structure of a kind of water ring pump that proposes for the utility model; As shown in Figure 2, for being the structural representation of screw-shaped impeller anti-loose spare among this Fig. 1.
With reference to accompanying drawing; The locking blade wheel structure of the water ring pump that the utility model proposes; Comprise impeller body 1; Axial interior threaded hole 11 is set on impeller body 1, comprises also by the steel wire coiling forming and being screw-shaped impeller anti-loose spare 2 that impeller anti-loose spare 2 is spun in the interior threaded hole 11 with certain pre-tensioning.
In the technique scheme; Locking blade wheel structure comprises by the steel wire coiling and forms and be screw-shaped impeller anti-loose spare; Impeller anti-loose spare is spun on certain pre-tensioning in the interior threaded hole of impeller body, and like this, pump shaft is installed in the interior threaded hole through impeller anti-loose spare; Be between screw-shaped impeller anti-loose spare and each pitch that is connected that the pump shaft screw thread carries out and be equivalent to be provided with a pressurized bullet pad, thereby with impeller body and the firm locking of pump shaft.Through above-mentioned setting, when the pump shaft counter-rotating of water ring pump, can avoid becoming flexible between pump shaft and the impeller, prevent that impeller from coming off from pump shaft, improved the stability and the reliability of water ring pump work.
As optimal technical scheme, under free state, the external diameter of impeller anti-loose spare is greater than the internal diameter of interior threaded hole; When being fit into interior threaded hole, thereby the external diameter of impeller anti-release member diminishes and forms certain pre-tensioning under the effect of external force, and is spun in the interior threaded hole; Like this; Be screw-shaped impeller anti-loose spare and can be securely fixed in the interior threaded hole, avoid from interior threaded hole, coming off, further improved the effect that impeller loosens because of the counter-rotating of pump shaft.
In concrete design process; The axial length that impeller anti-loose spare 2 can be set is less than or equal to the axial length of interior threaded hole 11; Like this; Can increase the area of contact of impeller anti-loose spare 2 and interior threaded hole 11, and can increase the area of contact between impeller anti-loose spare 2 and the pump shaft, make that its connection is more firm.
In technique scheme, said impeller anti-loose spare 1 is formed by the coiling of stainless steel steel wire.
The utility model has also proposed a kind of water ring pump; Comprise pump shaft and impeller, said impeller is above-mentioned locking blade wheel structure, and pump shaft is installed in the interior threaded hole 11 through impeller anti-loose spare 2; Thereby when the pump shaft counter-rotating of water ring pump; Can avoid becoming flexible between pump shaft and the impeller, prevent that impeller from coming off from pump shaft, improve the stability and the reliability of water ring pump work.
