Cushion block 2,1, square, chalk line or 2, steel wire；
Minor diameter tankage abutted flange concentricity measuring method:
1. the cylinder 1 having assembled burner pipe connecting flange 6 is vertically stood up and be placed on platform 3, first to each on the basis of platform 3
Pipe connecting flange 6 height h1 measures, and checks that each burner pipe connecting flange 6 is the most consistent, then opens with each pipe connecting flange 6
On the basis of checkpoint 7,4, the upper and lower, left and right in hole, measure checkpoint 7 the most equal to distance h2 of pipe connecting flange 6 cylindrical, and
Checking that distance h3 of left and right checkpoint 7 to burner pipe connecting flange 6 sealing surface is the most equal, upper and lower checkpoint is to burner pipe connection method
Distance h3 of blue sealing surface is the most equal, check each burner pipe connecting flange 6 bolt hole whether with respective Barrel alignment span centre
Uniform.
2. the on the premise of 1. an article measurement result is satisfied by requiring, to burner on the basis of pipe connecting flange 6 perforate centrage
Pipe connecting flange 6 bolt hole all separates 4 heart lines, and upper and lower line in fundamental disagreement must be with perforate centrage centering.
3. two pieces of equal height cushion blocks 2 are put in respectively two symmetrical pipe connecting flange 6 inwall heart lines and at flange sealing surface, and
Tightening chalk line 4 on cushion block 2, distance h4 between measurement pipe connecting flange 6 inwall to chalk line 4, every heart line is surveyed 6 points, and is surveyed
Distance h5 between amount platform 3 to chalk line 4,
4. removing cushion block 2, the bottom that two chalk lines 4 are directly placed at two symmetrical pipe connecting flanges 6 is united as one on line, tension powder
Line 4, with two chalk line 4 intersections as the center of circle, measures pipe connecting flange 6 sealing surface respectively to the whether phase of distance h6 between the center of circle
Deng, and with square 8, two intersecting lenses are measured, check that two butt tube flange 6 centrages are the most vertical.
The most every a pair symmetrical burner pipe connecting flange 6 is carried out said procedure measurement, two symmetrical pipe connection methods can be checked
Orchid 6 is the most concentric.
This measuring method compared with prior art has the advantage that
1, minor diameter, symmetrical two flanges of short distance tankage or the measurement of symmetrical two adapter concentricitys and centering are met, it is to avoid
The processing performance of equipment is affected because error is excessive.
2, survey tool is regular supplies, it is not necessary to additionally invest.
3, simple to operate, measurement size is the most accurate.
Accompanying drawing explanation
Fig. 1 minor diameter tankage abutted flange concentricity instrumentation plan,
4 pipe connecting flanges of Fig. 2 schematic diagram at 2 square crossing heart lines,
In figure: 1-cylinder, 2-equal height cushion block, 3-platform, 4-chalk line, 5-ruler or tape measure, 6 pipe connecting flanges, 7 inspections
Make an inventory of, 8 squares.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of this measuring method is described further, connects with gasification furnace burner on sidewall
As a example by pipe flange concentricity is measured.
The instrument that minor diameter tankage abutted flange concentricity is measured has: ruler or tape measure 5, platform 3, equal height cushion block 2,
Chalk line or steel wire 4, square 8.
During measurement, measurement cylinder 1 is positioned on platform 3, then to needing symmetrical pipe connecting flange 6 inwall measured to place
Equal height cushion block 2, tightens chalk line 4 above cushion block 2, distance h4 between symmetrical pipe connecting flange 6 inwall of measurement to chalk line 4, exists successively
Article four, heart line position measures.Wherein, heart line is the centrage that equipment is separated by outer circumference quarter.
Specifically measuring method is as shown in Figure 1:
1. the cylinder 1 having assembled burner pipe connecting flange 6 is vertically stood up and be placed on platform 3, first to each on the basis of platform 3
Pipe connecting flange 6 height h1 measures, and checks that 4 burner pipe connecting flange 6 height h1 are the most consistent, then with each pipe connecting flange 6
On the basis of checkpoint 7,4, the upper and lower, left and right of perforate, measure checkpoint 7 the most equal to distance h2 of pipe connecting flange 6 cylindrical,
And checking that distance h3 of left and right checkpoint 7 to burner pipe connecting flange 6 sealing surface is the most equal, upper and lower checkpoint to burner is taken over
Distance h3 of flange sealing surface is the most equal, check each burner pipe connecting flange 6 bolt hole whether with respective Barrel alignment across
In uniform.
2. on the premise of 1. an article measurement result is satisfied by pattern requirement, right on the basis of pipe connecting flange 6 perforate centrage
Burner pipe connecting flange 6 bolt hole all separates 4 heart lines, and upper and lower line in fundamental disagreement must be parallel with perforate centrage centering.
3. two pieces of equal height cushion blocks 2 are put in respectively two symmetrical pipe connecting flange 6 inwall heart lines and at flange sealing surface, and
Tightening chalk line 4 on cushion block 2, distance h4 between measurement pipe connecting flange 6 inwall to chalk line 4, every heart line is surveyed 6 points, and is surveyed
Distance h5 between amount platform 3 to chalk line 4, a butt tube is bottom or 1 heart line in the top measures.
4. as in figure 2 it is shown, remove cushion block 2, two chalk lines 4 are directly placed at the bottom one of two symmetrical pipe connecting flanges 6
On bar heart line, tension chalk line 4, with two chalk line 4 intersections as the center of circle, measure pipe connecting flange 6 sealing surface respectively between the center of circle
Distance h6 the most equal, and with square 8, two intersecting lenses are measured, check whether two butt tube flange 6 centrages hang down
Directly.
The most every a pair symmetrical burner pipe connecting flange 6 is carried out said procedure measurement, two symmetrical pipe connection methods can be checked
Orchid 6 is the most concentric.
