Description
Technical field
The utility model patent is mainly used in petrochemical industry, metallurgy, electric power, natural gas transportation, refrigeration and power etc.
National economy important department is a kind of new vertical subdivision type centrifugal compressor clearance measurement tooling.
Background technique
Vertical subdivision type centrifugal compressor as " heart " equipment of process industrial process units, Key generating unit, once
It breaks down and will lead to huge economic losses.And impeller be in vertical subdivision type centrifugal compressor it is most important, structure is the most multiple
Miscellaneous component realizes that from spindle machine can be the approach of raising gas energy to by the conversion of compression pressure energy.Cause
This, the radial direction and axial gap that rotor and stator are ensured when overhauling back dress are improved efficiency to gas loss is reduced with important
Meaning.
Currently, radially, axially clearance measurement and adjustment all generally use traditional measurement method, Team Member for rotor and stator
Exchanged with factory technician and careful inspection information after obtain traditional measurement method have following problem:
Internal-and external diameter mensuration is that gap width is roughly calculated by measurement rotor seal outer diameter and with seal stator internal diameter, by
In the gauge outfit of micrometer with sealing tooth tip it is that point, line contacts, and be sealingly fitted on compressor can not absolutely together for multiple groups
Axis, therefore error of measured data is bigger, the data of measurement are only for reference or other detection methods is cooperated to use.
Rubberized fabric method is to stick on a piece of adhesive tape in Labyrinth seal inner periphery, then by rotation steering wheel turn, pass through inspection after disassembly
The contact shade of different-thickness adhesive plaster is surveyed to determine gap width.It, can due to that must be previously placed on comb teeth when rotor installation
Adhesive plaster impression can be caused, secondly, cannot be guaranteed that adhesive plaster and each card slot firmly paste extremely when rubberized fabric, it may appear that Hanging sectionally
Situation, when measurement, will appear large error, wipe adhesive plaster off when resulting even in rotation rotor.
Clearance gauge method is that domestic enterprise applies a kind of increasingly extensive rotor radial and axially measured method in recent years.Use clearance gauge
It is filled between rotor and seal stator from split surface, thickness is between rotor and partition in the elastic suitable situation of clearance gauge
Gap.Clearance gauge itself is in uneven thickness, and transverse curvature amount when measurement also brings along very big influence, and accuracy is lower.Operating process
In also bite, sealing position also will appear burr frequent occurrence, both affected the air-tightness of device, also will increase measurement gap
Error.
Pressing lead wires method is that the galvanized wire of three groups of both the above different-diameters is pasted on sealing ring inner periphery, with rubberized fabric method phase
It is similar.During rotor is mounted on partition, it is difficult to ensure that double swerve and front and back play by a small margin do not occur for rotor,
It inevitably will appear false gap when measurement, therefore precision is not high.
False bearings supporting methods are measured suitable for radial clearance, and since rotor axial displacement is more difficult, axial gap is surveyed
Amount is inconvenient；Simultaneously because the screw pitch of bolt jack limits, the intense adjustment for carrying out radial clearance is more difficult.
Utility model content
Goal of the invention: the utility model provides a kind of measurement tooling, which can effectively improve internal-and external diameter traditional in factory

Problem.
Detailed description of the invention:
Fig. 1 is the front normal axomometric drawing of the utility model patent；
Fig. 2 is the two isogonism normal axomometric drawing up and down of the utility model patent；
Figure Plays:
1 support frame；2 channel steels；3 axis supports；4 upper beams；5 screw rods；6 pedestals；7 nuts；8 side shanks of bolt.
Specific embodiment:
As shown, the present apparatus can be divided into support section and measurement adjustment two parts composition.
There is a support platform on support section, pedestal 6, is used for fixing compressor inner casing lower cylinder body, support frame 1 is by four
Horizontal channel steel 2 and four vertical channel steels 2 are welded.Both ends upper beam 4 is placed on vertical channel steel 2 by overlapping mode packaged type
On, there is symmetrical bolt hole on upper beam.Two sides adjustment bolt 8 is welded on channel steel surface, adjusts rotor axial gap.
Adjustment member is measured, by upper beam, one end is fixed on takes out in support 3 the symmetrical upper beam screw rod 5 in two sides, realizes radial clearance
Adjustment.Side shank of bolt 8 uses adjustable bolt, and one end and 3 face of axis support are in close contact, and realizes axial gap adjustment.Axis support 3 is
Semicircular ring, inner surface are contacted with rotor, and two side axle supports 3 can be adjusted individually, and the measurements such as magnetic stand dress can be fixed in axis support 3
It sets, realizes the measurement to rotor clearance.
When in use, fixation problem is axially and radially measured in order to rationally solve rotor and inner cylinder, and does not influence turning for axis
Dynamic performance is checked by selection, intensity, rigidity and stability first from axis, determines that processing technology and machining accuracy are wanted
It asks, to meet clearance measurement, adjustment needs design the tooling with certain stiffness and strength；The measurement tooling is by pedestal 6, branch
Support 1 and a pair of adjustable support shaft support 3 form, and pedestal 6 and support frame 1 are welded by channel steel 2.Pedestal 6 is equivalent to V-type
