The device is fixed on a middle section surface of horizontal subdivision of equipment and is close to the sealing sheet, the rotor is driven by the unit with the barring gear, and the sealing sheet is processed by pulling the sealing sheet respectively through the relative position of the adjusting device and the sealing sheet, so that the limitation of processing equipment is broken, the sealing of the pulling-out order is realized by replacing the pulling-out order on the site of a user, and the efficiency of replacing the sealing sheet by pulling the out order is improved.
Description
Technical Field
The invention belongs to the technical field of movable turning equipment, and relates to a movable puller seal turning device.
Background
The seal between the rotating and stator parts of a turbomachine is generally a labyrinth seal, known as labyrinth seal in english and therefore commonly known in the art as a labyrinth seal. The sealing of the turbine machinery is realized by embedding a plurality of sealing teeth which are sequentially arranged on a rotating shaft, and processing steps with alternate heights or installing the sealing teeth at corresponding parts of a sealing stator, so that a series of flow-stopping gaps and expansion cavities are formed at the sealing parts, a sealed medium generates a throttling effect when passing through the gaps of a zigzag labyrinth, the pressure of the medium is reduced, and the purpose of leakage resistance is achieved.
Although the sealing is simple and efficient by the aid of the clamping ring and is widely applied to turbomachinery, due to the fact that fluid scours, vibration abrasion and the like exist, after the turbomachinery runs for a period of time, a sealing gap is enlarged, the sealing effect is reduced, the sealing piece needs to be replaced at the moment, and the turbomachinery is a loss piece. In the replacement process, the old sealing piece needs to be removed and then a new sealing piece is inlaid again, the new sealing piece usually leaves a machining allowance, and the excircle of each level of sealing piece is required to be properly machined on a lathe after the new sealing piece is inlaid, so that the requirement of designing a sealing gap is met.
Because turbomachinery draws to do not to make and seals the lathe work that needs to carry out after changing, consequently can only generally go on when the user is shut down and is overhauld, generally have two kinds of schemes: one method is that after a sealing sheet is embedded in a user site, a sealing gap is measured, a manufacturing plant with processing capacity is searched nearby, and the allowance of the sealing sheet is turned to meet the design requirement; and the other is that the rotor is directly returned to the original manufacturing plant for replacement and processing, so that the design requirement is ensured.
Above-mentioned two kinds of technical scheme, though can satisfy the change requirement of drawing the order of not ordering, all need transport the processing factory with the rotor, can not realize sealed field replacement, especially large-scale turbine's rotor weight is big, the span is long, turning radius is big, the sealed large-scale sleeping carriage that often needs more than 8m of turning can only return the rotor to former manufacturing plant and reprocess, causes sealed spare part to change to take trouble hard, is difficult to satisfy user's production demand.
Disclosure of Invention
The invention aims to provide a movable sealing and turning device for a pin, which has the characteristics of breaking the limitation of processing equipment, realizing the replacement of pin sealing in the field of a user and improving the replacement efficiency of a pin sealing sheet.
The technical scheme adopted by the invention is that a mobile tension order turning device is arranged on a horizontally split middle split surface of a unit and comprises a tool rest and a supporting plate; the backup pad is connected with the well facet of unit horizontal subdivision, and surface mounting has the slide rail in the backup pad, and the knife rest bottom is passed through knife rest fixing bolt and is connected with the slide rail.
Four corners of the supporting plate are respectively provided with connecting holes, and the supporting plate is connected with the horizontally-split middle split surface of the unit by bolts penetrating through the connecting holes.
The slide rail is of a rectangular structure, two ends of the bottom of the slide rail are provided with protruding steps, bolt through holes are further formed in the steps, and slide rail fixing bolts penetrate through the steps and then are connected with the supporting plate.
The middle of the slide rail is also provided with a long U-shaped groove, and the length of the long U-shaped groove is matched with that of the sealing piece.
The tool rest fixing bolt penetrates out of the bottom of the U-shaped groove of the sliding rail upwards and then is connected with the bottom of the tool rest.
And a turning tool is also arranged on the tool rest, and the end part of the turning tool is contacted with a sealing sheet on the main shaft sheet.
The invention has the beneficial effects that:
the device has the advantages that the structure of the supporting plate and the guide rail is simple, the material is easy to obtain and manufacture, and the installation size can be flexibly adjusted according to the specific screw hole position of the facet in the unit; this device is fixed on the well facet of equipment level subdivision, be close to the gasket, drive the rotor from taking barring gear through the unit, the rotational speed can satisfy the smear metal speed requirement, and easy operation, it is not high to operating personnel's study and technical requirement, and realize drawing the processing of making the gasket separately through the relative position of adjusting device and gasket, the restriction of processing equipment has been broken, can guarantee to accomplish the change task of gasket fast, shorten the time limit for a project by a wide margin, it is sealed to realize drawing the order separately at user site replacement, improve and draw and make the gasket change efficiency separately, promote customer experience.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1: a movable type pin seal turning device is arranged on a horizontally split middle split surface of a unit and comprises a tool rest 1 and a support plate 3; the support plate 3 is connected with a horizontally-split middle split surface of the unit, the upper surface of the support plate 3 is provided with a slide rail 2, and the bottom of the tool rest 1 is connected with the slide rail 2 through a tool rest fixing bolt 7.
Four corners of the supporting plate 3 are respectively provided with connecting holes 8, and the supporting plate passes through the connecting holes 8 through bolts to be connected with a horizontally-split middle split surface of the unit.
The slide rail 2 is of a rectangular structure, two ends of the bottom of the slide rail are provided with protruding steps, bolt through holes are further formed in the steps, and the slide rail fixing bolt 6 penetrates through the steps and then is connected with the supporting plate 3.
The middle of the sliding rail 2 is also provided with a long U-shaped groove, and the length of the long U-shaped groove is matched with that of the sealing piece 5.
The tool rest fixing bolt 7 penetrates out of the bottom of the U-shaped groove of the sliding rail 2 upwards and then is connected with the bottom of the tool rest 1.
The tool rest 1 is also provided with a turning tool 4, and the end part of the turning tool 4 is contacted with a sealing sheet 5 on a main shaft sheet 9.
The working process of the device is as follows:
