Abstract
The utility model discloses a steam turbine gland clearance caliber, including the measuring device who measures support and installation, set up the gauge stick that has the digital display percentage table in the support mesopore on the measuring device, connect in measuring the sword through the table nipple on it, the bilateral symmetry of support body is equipped with the stabilizer blade and constitutes. The device has the characteristics of simple and convenient use and operation, low labor intensity, high speed measurement and high precision.
Description
The utility model relates to a kind of overhaul of steam turbine, adjustment servicing unit, relates to a kind of Gland Clearance in Steam Turbine measuring appliance specifically.
Steam turbine must have a labyrinth clearance between the packing tongue and groove of labyrinth ring crown and rotor under assembled state, reach the technological standards value for guaranteeing this labyrinth clearance, behind the every operation certain hour of steam turbine, all needs this labyrinth clearance is remeasured and adjusted.Because turbine shaft seal, gland seal structure compactness add that rotor blade is longer, increased the difficulty that the labyrinth clearance is measured.Therefore, the existing common practice is to press medical proof fabric, and adopts naked eyes, judges gap value by rule of thumb.So can only do qualitative analysis, out of true very, and need repeated multiple times to measure, efficient is low, when measuring by measurement mechanism, also every labyrinth ring must be taken out the conduit in cylinder, causes dismounting labour intensity big.
The purpose of this utility model is for solving the problem in the above-mentioned technology, and a kind of Gland Clearance in Steam Turbine measuring appliance is provided, and can detect the original gap width of packing easily, and is easy and simple to handle, speed is fast, measuring accuracy is high.
For achieving the above object, the utility model is finished by the following technical programs: the Gland Clearance in Steam Turbine measuring appliance, the measurement mechanism that comprises measurement bracket and installation thereof, its measurement mechanism is by inserting the table bar that has digital display centimeter in the through hole on its support body, after the table bar can be adjusted up and down along through hole, by adjusting the button location, the sounding rod end of extending in table bar bottom is installed a table and is connect cover, and it is fastening by screw, table connects in the hole slot of bottom of cover the measurement cutter is set, flexibly connect by swivel pin, sounding rod top has can spur the draw ring that the sounding rod body drives the upper and lower displacement of measurement cutter, be provided with the navigation button of control survey bar displacement on the table bar of the arbitrary end of digital display centimeter, the symmetria bilateralis of support body installs and measures leg and constitutes.
The Gland Clearance in Steam Turbine measuring appliance of the technical program also comprises in measuring use by sampling silicon lotion is set between the bottom of measuring cutter and the tested labyrinth ring.Utilize sampling silicon lotion that rotor packing groove is filled up fully to the gap of labyrinth ring crown, be the zero stand-off.Digital display centimeter by measuring appliance can directly be read original gap width.Obtain required labyrinth clearance value by changing trimmer.
Gland Clearance in Steam Turbine measuring appliance of the present utility model utilizes special sampling silicon lotion to cooperate with measuring appliance, can have and measure the labyrinth clearance value easily and quickly and adjust to the right place, the labyrinth clearance value degree of accuracy of measuring is greatly improved, both alleviated labour intensity, shortened duration again to the steam turbine overhaul, this improves unit output to improving unit safety operation, reduces energy consumption and all has positive meaning.
Below in conjunction with accompanying drawing embodiment to this novel being further described.
Fig. 1 is a Gland Clearance in Steam Turbine measuring appliance topology view.
Fig. 2, Fig. 3 are another embodiment of Fig. 1 support body leg.
Fig. 4 is the surveying work view.
By shown in Figure 1, the Gland Clearance in Steam Turbine measuring appliance, it has has adopted digital display centimeter 2, the table bar 3 that also has disjunctor on it, table has the sounding rod 7 that body with it relatively moves in the bar 3, its top is provided with draw ring 1, the table bar 3 that has digital display centimeter 2 is inserted in the through hole at support body 4 centers, the position of the corresponding through hole of support body 4 one sides is equipped with and is adjusted button 5, can be in order to control along the adjustment location of the table bar 3 of through hole upper and lower displacement, in the through hole that radially has of the table bar 3 of digital display centimeter 2 arbitrary end positions, be provided with the navigation button 12 of control survey bar 7 upper and lower displacements, by the end of extending of sounding rod 7 table is installed and is connect cover 8, fastening by screw 9, sounding rod 7 bottoms have a hole slot, are provided with in it to measure cutter 11, the swivel pin 10 that the utilization table connects on the cover 8 flexibly connects, and fuse with sounding rod 7, when pulling draw ring 1, drive by sounding rod 7 and to measure cuttves 11 and move up and down.Measure cutter 11 and connect cover 8 oscillating quantities that have approximately about 2mm, in symmetria bilateralis measurement device leg 6 formations of support body 4 with respect to table.
The support body leg of this measuring appliance is " mouth " shape, has stability when measuring with assurance.
Fig. 2 is the another kind of version of Fig. 1 measuring appliance support body leg.It is for the support body leg 6 that guarantees symmetry with becoming on the basis of three fulcrums on the cambered surface of measuring cuttves 11 and tested labyrinth ring, to the leg 6 of bending shape be installed on support body 4 one sides, L-shaped shape body and footing are the symmetrical step of two horizontal distribution, can satisfy as shown in Figure 1 structure and functions of use equally.
Fig. 3 is provided with measurement leg 6 and be listed on support body 4 the same sides, constitutes two fixed points of the same side, the table bar 3 of moving point wherein and have the outside that sounding rod 7 is installed in two legs 6.The shape of its leg 6 such as the leg unanimity among Fig. 1.The measuring appliance of this version can be used for detecting between the adjacent labyrinth ring whether smooth connection.Whether unanimity just comes into plain view by the reading value that detects.
Fig. 4 has provided the surveying work state of labyrinth clearance measuring appliance.Promptly sample 14 pairs of tested rotor packing grooves of silicon lotion to the gap complete filling of labyrinth ring between cog completely by special auxiliary body earlier before the surveying work, draw ring 1 pull-up of measuring appliance is driven measurement cutter 11 simultaneously, measuring appliance support body leg 6 is contacted on the tested labyrinth ring 13, put down draw ring 1 gently and make measurement cutter 11 contact gland sealing ring 13 measured surfaces gently, digital display centimeter 2 is adjusted return-to-zero, mentioning measuring appliance then collapses support body leg 6 and is placed on the both sides of tested labyrinth ring 13 measured points samplings silicon lotion 14, make and measure on the cutter 11 corresponding contact sampling silicon lotions 14, the reading on the digital display centimeter 2 is gap width.
When the on-the-spot detection of measuring appliance, owing to the restriction of environment or condition, can not directly see the numerical value of digital display centimeter 2 clearly, need detected gap width record location; Can finish by the navigation button 12 of table bar 3.
