One side of the scales of the measuring stands is symmetrically provided with measuring cards with indication marking lines connected through a regulating apparatus. The front ends of the measuring cards are provided with measuring hooks. The gas wheel machine gas sealing ring gap regulating measuring device has the advantages of reasonable design and portable use and is suitable for any machine type. At present, the gas wheel machine gas sealing ring gap regulating measuring device is the ideal regulating measuring tool.
Description
The utility model relates to a kind of overhaul of steam turbine, adjustment servicing unit, relates to a kind of turbine steam seal czermak space specifically and adjusts measuring appliance.
Usually learning Gland Clearance in Steam Turbine, is after measuring data by the labyrinth clearance measuring appliance, need adjust the labyrinth ring that the gap is bigger than normal or less than normal.Existing that perception method be, before the adjustment, the labyrinth ring of needs adjustment is inserted in the mold of measurement mechanism, utilize measuring table to measure by dial gauge, write down and set up data archival.Labyrinth ring is inserted in the mold again and detect adjustment amount on measurement mechanism after adjusting, till adjusting to the right place.Because mold is the simulation dividing plate, what the design of axle big envelope conduit was produced is single type, and need the configuration measurement mechanisms that overlap for different type of machines, different size etc. more, and the measurement form is numerous and diverse, therefore, do not have general interchangeability, bring the unnecessary trouble and the waste of measurer for the adjustment work of labyrinth ring gap yet.
The purpose of this utility model provides a kind of turbine steam seal czermak space and adjusts measuring appliance, and it can adapt to the measurement of different type of machines labyrinth ring gap data, and convenient and swift.
For achieving the above object, the technical solution of the utility model is achieved like this: a kind of turbine steam seal czermak space is adjusted measuring appliance, the measuring appliance blade that comprises employing, by the digital display vernier that a removable cooperation is installed on the blade, wherein it is the measurement bay that sets up and have scale in the front end of digital display vernier body to symmetria bilateralis separately, scale one side symmetry on measurement bay is installed the measurement card that is provided with the indication groove, be stuck in displacement and location on the measurement bay by the measurement of adjusting gear regulating and controlling, collude by the front end amount of having of measuring card and constitute.
The characteristics that the utility model compared with prior art has are: it does not need measuring table and mold, utilize adjusting measuring appliance directly acts on the big convex surface of the little convex surface of tested non-adjustable labyrinth ring and carrying plane or adjustable labyrinth ring and adjusts on the piece, and demonstrate dimensional data by the digital display vernier, after the processing carrying plane is adjusted, measure data again, make the data difference before and after adjusting be actual adjustment amount.Have the measuring accuracy height, method is quick, and can adapt on any type and use, be that apparatus is measured at present comparatively desirable adjustment.
Below in conjunction with accompanying drawing embodiment to the concrete description of this novel do.
Fig. 1 adjusts the measuring appliance topology view for the turbine steam seal czermak space.
Fig. 2 is the measuring head cut-open view of Fig. 1.
Fig. 3 is another embodiment cut-open view of measuring head.
Fig. 4 is another embodiment of blade.
Fig. 5,6 is for measuring view.
By Fig. 1, shown in Figure 2, the turbine steam seal czermak space is adjusted measuring appliance, it has the bar shaped blade 1 of employing, digital display vernier 2 is installed on the blade 1, and have display window on the digital display vernier 2, distribute and have the measurement bay 3 of scale to symmetria bilateralis by digital display vernier 2 body front ends, measurement bay 3 is the convex-concave plane, set scale on the protruding platform, the concave plane is provided with chute 4, and on the concave plane of measurement bay 3, be provided with removable and have the measurement card 5 of indicating groove, measure the adjustment hole 7 that has displacement on the card 5, make on its horizontal counterface of measuring card 5 and measurement bay 3 to have protruding feather key 9, cooperate with chute 4, and utilize and adjust the measuring head that screw 6 is formed, by measuring the whole adjusting gear of forming in 7 location, adjustment hole on the card 5.The other end of blade 1 can be along the middle part telescopic displacement of measurement bay 3, and the data of displacement are shown by the display window on the digital display vernier 2.
Fig. 3 is the measurement bay 3 among Fig. 1 and measures another version that card 5 cooperates the formation adjusting gear.It is utilize to measure on card 5 and 3 liang of vertical counterfaces of measurement bay, have the chute 4 and the feather key 9 that cooperatively interact respectively, on the recessed end face of measurement bay 3, have deep gouge 10, and measure the nut 11 that on the counterface of card 5 evagination is arranged and have screw, be placed in the deep gouge 10, handle screw 13 by configuration inserts measurement bay 3 outer side through hole and the deep gouge 10 interior nuts of measuring on the card 5 11 that are connected by locknut 12 respectively, make handle screw 13 insert the other end of deep gouges 10, be fixed on the measurement bay 3 by locknut 12 by an end of handle screw 13 and form.When turning handle screw 13, drive measurement card 5 and do the linear reciprocation displacement.
Fig. 4 is equipped with block 14 by the front end that is positioned at measurement bay 3 middle part blades 1, and block 14 can be pulled down by blade and be flexibly connect, and amount is colluded 8 and is the convex-concave shape.
Fig. 5 measures view for measuring appliance.When this measuring appliance is measured non-adjustable labyrinth ring state, concrete measuring method is: the amount on the card 5 will measured is colluded 8 carrying planes 17 that catch on labyrinth ring 15, the front end of mobile blade 1 props up the little convex surface 18 of labyrinth ring 15, and the data of blade 1 displacement demonstrate dimensional data by the display window of digital display vernier 2.Make carrying plane 17 after processing is adjusted, measure data with above-mentioned same method, the data difference before and after adjusting is actual adjustment amount.
Measuring method for adjustable labyrinth ring is: will measure tolerance and collude the big back of the body arcwall face 16 that 8 perpendicular end surface props up labyrinth ring 15, the front end of mobile blade 1 props up the adjustment piece (because of adjustable labyrinth ring is not with carrying plane and little convex surface) of labyrinth ring 15, the data of blade 1 displacement are by digital display vernier video data, after adjusting the pad change, with measuring data with quadrat method, the data difference before and after adjusting is actual adjustment amount.
Fig. 6 is another kind of metering system.When changing above-mentioned metering system, can block 14 be installed in the front end of blade 1, utilization colludes 8 convexconcave part on the carrying plane 17 of labyrinth ring 15, is acted on by block 14 on the long tooth of labyrinth ring 15, shows displacement scale by the digital display vernier.
