Abstract
The utility model relates to a dismantlement tool of an impeller of a centrifugal compressor. Through holes are arranged in the middle portion and at the two ends of a fixing horizontal rod. A spindle is installed in the through hole in the middle of the fixing horizontal rod. One end of the spindle is provided with a conical section increasing outwardly, an expansion sleeve and a locating separating sleeve are sequentially sleeved on the spindle, and the other end of the spindle penetrates through the fixing horizontal rod to be fastened by a tensioning nut. A stud bolt is respectively installed in the through holes at the two ends of the fixing horizontal rod, one end of each stud bolt is in threaded connection with a fixing nut, a fixing separating sleeve is sleeve on each stud bolt, the other end of each stud bolt penetrates through the fixing horizontal rod to be fastened by each fixing nut, and each fixing separating sleeve and the conical section of the spindle are located on the same side of the fixing horizontal rod. The spindle is used for expanding the expansion sleeve, the spindle, the expansion sleeve and the impeller are integrated, and then the tensioning nut is screwed to enable the impeller to be separated from a locating pin so as to be dismantled successfully. The dismantlement tool of the impeller of the centrifugal compressor is simple and reliable in structure and fast and safe to dismantle.
Description
Technical field
The utility model relates to centrifugal compressor, specifically a kind of extracting tool of Centrufugal compressor impeller.
Background technology
The impeller of centrifugal compressor is fixed on the fixed disk through alignment pin, and the rotating speed of impeller often all wants per minute several ten thousand to change above 24 hours of continuous run, and operating temperature is very high, and after the work a very long time, impeller is difficult to break away from from alignment pin.
At present, a kind of method of dismounting impeller is on the end face of impeller, screwed hole to be set, and connects extracting tool and dismantles; But because reasons in structure, the impeller section is very little, and screw thread is done lessly; Adding impeller material is aluminum, and screw thread is unable to eat power, causes impeller to damage easily and does not tear open not get off.
Summary of the invention
The utility model provides a kind of extracting tool of Centrufugal compressor impeller to the problems referred to above, and this instrument can be dismantled impeller quickly and safely, and not fragile impeller.
Technical scheme according to the utility model: a kind of extracting tool of Centrufugal compressor impeller; Middle part and two ends at fixed transverse rod all have through hole; In the through hole at said fixed transverse rod middle part mandrel is installed; One end of said mandrel is provided with the conical section of outside increase, is with expansion set and positioning spacer on the said mandrel successively, and the other end of said mandrel passes behind the said fixed transverse rod fastening by tightening nut; Be separately installed with studs in the through hole at said fixed transverse rod two ends; The threaded one end of said studs is connected with hold-down nut; Be with fixedly spacer on the said studs; The other end of said studs passes behind the said fixed transverse rod fastening by hold-down nut, and the conical section of said fixedly spacer and said mandrel is positioned at the same side of said fixed transverse rod.
The rear end of said expansion set is provided with the taper hole that matches with said mandrel conical section.
Be lined with packing ring respectively under said tightening nut and the said hold-down nut.
Said mandrel and said expansion set insert the non-locating hole of impeller, and said fixed transverse rod is installed on the fixed disk of said impeller through said fixedly spacer.
The technique effect of the utility model is: the utility model passes through mandrel with the expansion set spreading; Through the frictional force between expansion set and impeller mandrel, expansion set and impeller are become one; Make impeller break away from alignment pin and successfully dismounting through revolving tightening nut again, simple and reliable for structure, dismounting is quick, safety.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Be further described below in conjunction with the specific embodiment of accompanying drawing the utility model.
Among Fig. 1, comprise fixedly spacer 1, alignment pin 2, fixed disk 3, studs 4, hold-down nut 5, fixed transverse rod 6, impeller 7, expansion set 8, tightening nut 9, mandrel 10, positioning spacer 11 etc.
As shown in Figure 1, the utility model is a kind of extracting tool of Centrufugal compressor impeller, comprises the fixed transverse rod of being processed by steel pipe 6, all has through hole at the middle part and the two ends of fixed transverse rod 6.
In the through hole at fixed transverse rod 6 middle parts mandrel 10 is installed, an end of mandrel 10 is provided with the conical section of outside increase, is with expansion set 8 and positioning spacer 11 on the mandrel 10 successively, and it is fastening by tightening nut 9 that the other end of mandrel 10 passes fixed transverse rod 6 backs.
Be separately installed with studs 4 in the through hole at fixed transverse rod 6 two ends; The threaded one end of studs 4 is connected with hold-down nut 5; Be with fixedly spacer 1 on the studs 4; It is fastening by hold-down nut 5 that the other end of studs 4 passes fixed transverse rod 6 backs, and fixedly the conical section of spacer 1 and mandrel 10 is positioned at the same side of fixed transverse rod 6.
The rear end of expansion set 8 can also be provided with the taper hole that matches with mandrel 10 conical sections, in order to increase the contact area of mandrel 10 conical sections and expansion set 8.
Also be lined with packing ring respectively 5 times at tightening nut 9 and hold-down nut.
When the utility model uses; With the conical section of mandrel 10 and the non-locating hole of expansion set 8 insertion impellers 7; On mandrel 10 expansion sets 8, put positioning spacer 11 again, then fixed transverse rod 6 is enclosed within on the mandrel 10, fixing spacer 1 on pad between the fixed disk 3 of impeller 7 and the fixed transverse rod 6; Fixedly putting on studs 4 in the spacer 1, and through tightening nut 9 and hold-down nut 5 fastening fixed transverse rods 6.Then tighten tightening nut 9; Make mandrel 10 with expansion set 8 tensioners on the non-locating hole of 7 second half sections of impeller; Impeller 7 and mandrel 10 and expansion set 8 are become one, then positioning spacer 11 is removed, break away from alignment pin 2 to impeller 7 and successfully dismounting through revolving tightening nut 9 again.
With expansion set 8 spreadings, the frictional force through 7 in expansion set 8 and impeller is located mandrel 10 to the utility model, and is simple and reliable for structure, can dismantle impeller 7 quickly and safely through mandrel 10.
