Abstract
The utility model relates to an axial gap regulator for a blade wheel, which is composed of a rotor which is provided with a connecting part for connecting the blade wheel. The connecting part is provided with a protruding end which is coaxial with the rotor and is provided with a regulating nut. The regulating nut is provided with a bolt connecting hole in which a bolt is arranged. The protruding end is also provided with a fixed nut. The blade wheel is sheathed on the protruding end and is arranged between the regulating nut and the fixed nut. The blade wheel is provided with a through hole, and the bolt penetrates through the through hole to be fixed with a bolt connecting hole. When the blade wheel is abraded and the clearance between the blade wheel and the inner end surface of a pump cover enlarges, the fixed nut and the bolt can be disassembled, the blade wheel is regulated axially to a proper position, the regulating nut is rotated to be even with the blade wheel, the regulating nut and the blade wheel are combined into integration with the bolt, and finally the fixed nut is screwed tightly for preventing the loosening phenomenon. In such a way, the blade wheel in a pump body can be regulated to an ideal axial position stably without suspension structure redesign. The utility model has the advantages of simple and reliable structure and easy assembly.
Description
Technical field:
The utility model relates to mechanical pump, relates in particular to open impeller pump, and particularly the impeller shaft in the open impeller pump is to gap adjusting structure, and concrete is a kind of impellor shaft axial clearance adjusting mechanism.
Background technique:
In the prior art, open impeller pump is made of the pump housing, suspension and rotor, the described pump housing is connected with suspension, described rotor is located in the pump housing and the suspension, in the described pump housing, be provided with impeller, be provided with pump cover, be provided with cover plate in the outside of impeller in the inboard of impeller, one end of described rotor is one side-prominent suspension, and the other end is connected with impeller; When above-mentioned open impeller pump was carried liquid thickness or that contain solid particle, impeller was worn easily, caused the gap increase between the interior edge face of impeller and pump cover, influenced the stable operation of pump group; In order to overcome this problem, existing technical scheme is by adjusting the axial position of whole rotor, thereby realizes the adjustment in the gap between impeller and the pump cover; But adopt existing gap adjustment technology, it is more often to cause suspension frame structure complexity, component part to increase, and can not utilize the suspension of pump with enclosed impellers, need develop a kind of suspension of special use again, causes problems such as cost rises, assembling difficulty.
Summary of the invention:
Technical problem of the prior art to be solved in the utility model is: because in the prior art, the adjustment in the gap between impeller and the pump cover is to realize by the axial position of adjusting whole rotor, often cause suspension frame structure complexity, component part to increase more, and can not utilize the suspension of pump with enclosed impellers, need develop a kind of suspension of special use again, cause problems such as cost rises, assembling difficulty.Suspension frame structure complexity, component part are more, cost height, assembling difficulty.
The utility model provides a kind of impellor shaft axial clearance adjusting mechanism for the technological scheme that solves above-mentioned technical problem of the prior art and adopt, described this impellor shaft axial clearance adjusting mechanism is made of a rotor, described rotor has a joint that connects impeller, wherein, has a protruding terminus on the joint of described rotor, described protruding terminus and described rotor are on same axis, described protruding terminus is provided with one and adjusts nut, at least be provided with a screw connecting hole on the described adjustment nut, be provided with screw in the described screw connecting hole, also be provided with a set screw nut on the described protruding terminus, described set screw nut is arranged on the outside of described adjustment nut.
Further, described protruding terminus is provided with screw thread, and described adjustment nut is connected with described protruding terminus by screw thread with set screw nut.
Further, be arranged with an impeller on the described protruding terminus, described impeller is between described adjustment nut and set screw nut, described impeller with described adjustment nut on the corresponding position of screw connecting hole be provided with through hole, described screw passes described through hole and described screw connecting hole is fixed.
Further, described adjustment nut is provided with three screw connecting holes, and described three screw connecting holes are that radiuses such as the center of circle are evenly spaced apart with the axle center of described adjustment nut.
Working procedure of the present utility model is: after the gap of damage in impeller, impeller and cover plate increases, unload set screw nut and screw, axially adjust impeller to correct position, rotation is adjusted nut and is made itself and impeller snap then, nut will be adjusted with screw then and impeller is coupled as one, the nut that is tightened at last is to prevent loosening phenomenon.Like this, the impeller in the pump housing is just firmly adjusted to desirable axial position, and need not redesign the structure of suspension.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is by adjusting nut and set screw nut changes and the fixing axial position of impeller, nut will be adjusted and impeller is coupled as one by screw, so need not redesign the adjustment that the wing pump suspension just can be realized the gap between impeller and the pump cover, simple and reliable for structure, assembling easily.
