Abstract
The utility model discloses a liquid pipe mounting tool is drawn in import of forced circulation pump, pump body import is equipped with the pull rod, and the upper portion of pull rod is the conical body, and pull rod axial bottom is equipped with a backup pad, and the nut passes backup pad central authorities to be connected with the pull rod, and the excircle circumference equilibrium on pull rod top sets up three the same fixed block, still includes the guide bar of two symmetry settings, and the guide bar is located on the diffuser of circulating pump. Use the utility model discloses afterwards, the horn tube can not produce any deformation, has guaranteed sealed effect.
Description
Technical field
The utility model relates to physical construction, is specifically related to a kind of forced circulation pump import liquid guiding tube setting tool.
Background technology
The water circulating pump of thermal power plant's high-temperature high-pressure boiler, installation mode is inverted installation (see Fig. 1). Because the import and export that the environment used is High Temperature High Pressure, inlet/outlet pipeline and recycle pump are connected by the mode of welding, installation and maintenance are made troubles by such mode of connection. The installation mode of pump is: is first installed on the pump housing 2 by stator body 1, and is fixed with bolt 1; And then piston ring 4 is installed on loudspeaker pipe 5, finally piston ring 4 is pressed into together with loudspeaker pipe 5 pump housing import 7, tightens bolt 26, import loudspeaker pipe is fixed, finally by pump housing import 7, outlet together with pipeline welding, complete the pump housing and install. This kind installs the shortcoming of mode: in the import and export and pipeline welding process of pump, loudspeaker pipe and piston ring are easily out of shape, and cause the liquid of outlet again to flow into import, reduces result of use; After pump import and export welding completes, it is necessary to the quality of welding being carried out test high pressure inspection, prevents the leakage because welding quality causes, the pump housing bears in high-pressure process, also easily causes the deformation of loudspeaker pipe. Therefore, import and export at the pump housing and complete with pipeline welding, after carrying out high-potting, then stator body, loudspeaker pipe and piston ring are installed, so just can effectively ensure sealing effect. But because pump is installed as inverted installation, piston ring coordinates very tight with pump import, makes installation first weld, pressure testing, then it is very difficult again to install stator body, loudspeaker pipe and piston ring.
Practical novel content
After using the utility model, loudspeaker pipe can not produce any deformation, ensure that sealing effect.
In order to achieve the above object, the utility model has following technical scheme:
A kind of forced circulation pump import liquid guiding tube setting tool of the utility model, comprise a pull bar, the axial bottom of described pull bar is provided with a back up pad, and a nut is connected through back up pad central authorities with pull bar, and the excircle on described pull bar top arranges three identical fixed blocks to equilibrium.
Further, also comprising two symmetrically arranged tail rods, tail rod is located on the stator body of recycle pump.
Further, the top of described pull bar is cone-shaped body.
Further, the outside surface tapering of fixed block is identical with pump import tapering, and the internal surface tapering of fixed block is identical with the tapering on pull bar top.
Owing to taking above technical scheme, the utility model has the advantage of: by taper pull bar by power effect, loudspeaker pipe is installed in the inlet pipe of pump. Installing force, by after power, by the cooperation of cone-shaped body, is applied on the pump housing and the pipeline that installs by taper pull bar, and solving import loudspeaker pipe cannot the problem of vertical installation.
It is uniform that loudspeaker pipe is screwed into, and can not produce any deformation, simultaneously because bolt can bear bigger power, it is possible to carry out the installation of relatively wringing fit, ensures that sealing is reliable, and it is also best for therefore sealing effect.
Accompanying drawing explanation
Fig. 1 is tradition structural representation;
Fig. 2 is the utility model application structure schematic diagram.
In figure: 1-stator body 2-pump housing 3-bolt one 4-piston ring 5-loudspeaker pipe 6-bolt two 7-pump housing import 8-pull bar 9-fixed block 10-back up pad 11-nut 12-tail rod
Embodiment
Hereinafter implement for illustration of the utility model, but it is not used for limiting scope of the present utility model.
See Fig. 2, pump housing import 7 centre arranges pull bar 8, and the top of pull bar 8 is cone-shaped body, and the axial bottom of pull bar 8 is provided with a back up pad 10, one nut 11 is connected through back up pad 10 central authorities with pull bar 8, and the excircle on pull bar 8 top arranges three identical fixed blocks 9 to equilibrium; The stator body 1 of recycle pump is symmetrical arranged two tail rods 12.
When pump housing import 7 and outlet and pipeline welding complete, after carrying out pipeline pressure testing, the stator body 1 separated is installed in the pump housing 2, tightens the bolt 1 installing stator body, complete the installation of stator body 1, more logical the utility model instrument, it is achieved the installation of loudspeaker pipe 5.
Three fixed blocks 9 are installed by ingress at pump, the outside surface tapering of fixed block 9 is identical with pump import 7 tapering, internal surface tapering is identical with pull bar 8 tapering, namely the outside surface of solid piece 9 and pump import 7 internal surface are suitable, internal surface and the pull bar 8 upper taper external surface of solid piece 9 are suitable, when pull bar 8 down moves, pull bar 8, by power, is strained by fixed block 9; By nut 11, constantly loudspeaker pipe 5 is up moved, until being screwed into the import of pump completely, loudspeaker pipe 5 uniform force being screwed into like this, reliably. More excellent, stator body 1 is installed two tail rods 12, when loudspeaker pipe 5 is upwards moved, in the right direction, do not produce to rotate; After completing loudspeaker pipe 5 installation, turn on nut 11, take off tail rod 12 and back up pad 10; Pull bar 8 is up moved, so just can easily take out three fixed blocks 9, then remove pull bar 8, complete the installation of loudspeaker pipe 5.
By this technological development, the product (pump-type number: LUVAC2 �� 350-500/1) being applied to my company, in the erecting stage of India, solves on-the-spot installation problem in time. Meanwhile, by the Series Design to this structure, also may be used in the installation of like product.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to enforcement mode of the present utility model. For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description. Here cannot all enforcement modes be given exhaustive. Every belong to apparent change that the technical solution of the utility model extended out or variation is still in the row of protection domain of the present utility model.
