Abstract
The utility model discloses a lifting device of a vertical pump rotor. The problem that centering adjustment is difficult in the regulating process of an existing vertical pump is solved. The lifting device of the vertical pump rotor comprises a lifting piece which is arranged on the exposed shaft section of a pump shaft in a sleeved mode. The inner wall of the lifting piece is in screw-thread fit connection with the outer wall of the pump shaft, a structure which enables the lifting piece to be rotated conveniently is arranged on the outer wall of the lifting piece, and the lifting piece is provided with connecting holes which enable the lifting piece to be fastened on a supporting seat or a pump coupler through fasteners. The lifting device of the vertical pump rotor solves the problems of rotor component lifting and flow pass centering on a mounting base layer after a vertical pump is completely assembled, and guarantees the smooth operation of the pump.
Description
Technical field
The utility model relates to field of fluid machinery, is specially a kind of vertical pump rotor lifting device.
Background technique
Vertical pump is formed by connecting by one section or several sections of axles conventionally.After installation, in order to guarantee running clearance and the runner centering of vertical pump, need to adjust.The method adopting at present a lot of situations is: in the process of rotor part is installed, by accessory size, reserved certain running clearance, though this way is feasible, but the position skew causing due to the machining error of accessory size and the accumulated size error of a plurality of parts, so that reserved running clearance changes, the regulating power of this way is poor, tends to cause part do over again or scrap.
Model utility content
In order to overcome above shortcomings in existing vertical pump adjustment process, the utility model aims to provide a kind of vertical pump rotor lifting device, this lifting device can, by after the whole installations of vertical pump, the method for carrying out outside adjusting on base layer is installed, ensure the smooth running of pump.
To achieve these goals, the technological scheme that the utility model adopts is:
A vertical pump rotor lifting device, its structural feature is to comprise that being sleeved on pump shaft exposes the lifting member on shaft part; The inwall of described lifting member and the outer wall thread of described pump shaft are connected; Described lifting member outer wall is provided with the structure of being convenient to rotary lifting part; The lower end surface of described lifting member contacts with the upper-end surface of supporting base or pump coupling, in this lifting member, have when rotor promote by fastening piece, lifting member is fastened on supporting base after putting in place or pump coupling on attachment hole.
Be below the technological scheme of further improvement of the utility model:
Further, described lifting member outer wall is provided with draw-in groove, is convenient to adopt the rotation of Hook wrench rotary lifting part.
Preferably, described fastening piece is Cock screw, and described lifting member is fixed on described supporting base or on pump coupling by the Cock screw through attachment hole.
By said structure, lifting member by with being threaded on pump shaft, thereby adopting Hook wrench to rotate lifting member drives pump shaft up to move, the most important running part-impeller of vertical pump is fixed on pump shaft, by lifting member, promote rotor part and regulate the axial clearance between impeller and pump housing fixed component, after promoting, lifting device is locked on supporting base by Cock screw, supporting base in the process of pump running along with pump shaft rotates together.
Compared with prior art, the beneficial effects of the utility model are: the utility model has solved vertical pump can be by installing the problem of carrying out rotor part lifting and runner centering on base layer after all having assembled.And by threaded adjusting facilitate and lifting capacity precision high; Lifting device is arranged on mounting layer basis, easy to operate; Employing special spanner is adjusted, and adjusts and becomes easily simple.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
