Description
Technical field
The present invention relates to a kind of methods of control inner and outer ring difference of height deformation, and in particular to a kind of control low pressure ring type partition
The method that inner and outer ring difference of height deforms after welding, belongs to steam turbine equipment field.
Background technique
Conventional Steam Turbine low pressure ring type partition is made of partition outer ring, partition inner ring, guide vane, and argon arc welding is used after assembly
It is welded, position while welding is respectively at the position that guide vane is connect with partition outer ring, partition inner ring.When partition erection welding, first will
Steam output side is upward, after assembling guide vane, welds steam output side weld seam, then workpiece is attached to welding steam admission side weld seam on positioner.Due to
Low voltage partition plate general size is larger, and welding capacity is also larger, and biggish heat input causes partition postwelding to shrink, and causes throat dimension super
Difference, partition inner and outer rings difference of height is inconsistent, occurs axial phenomenon of grinding one's teeth when often closing half after partition welding.This kind of partitions by
Big, the unstable quality in weld industry difficulty.
Summary of the invention
The present invention is solves the problem of that partition due to the big unstable quality of weld industry difficulty, and then proposes to control
The method that inner and outer ring difference of height deforms after the welding of low pressure ring type partition.
The technical solution adopted by the present invention to solve the above problem is as follows: specific step is as follows for the method for the invention:
Step 1: assemble in diaphragm inner ring and partition outer ring；
Step 2: drawing round wires and pitch lines in partition inner ring, round wires and pitch lines are drawn on partition outer ring；
Step 3: assembling guide vane between partition inner ring and partition inner ring, and check whether fitted position complies with standard；
Step 4: the steam output side weld seam of welding diaphragm；
Step 5: partition steam output side is loaded upward；
Step 6: welding diaphragm steam admission side weld seam；
Step 7: completing partition welding, check whether each size of partition and weld size comply with standard.
Further, guarantee that horizontal error is not more than 0.5mm during assemble in diaphragm inner ring and partition outer ring in step 1,
And ensure that partition inner ring and partition outer ring are concentric.
Further, in step 2 with leveling ruler, advise and mark horizontal middle separated time respectively in partition inner ring and partition outer ring
And vertical middle separated time, and horizontal middle separated time and vertical middle separated time extend respectively on the end face of partition inner ring and partition outer ring；Every
Plate inner ring and the pitch of partition outer ring will uniformly correspond to adjustment, finally draw quasi- pitch lines, and stamp foreign dotting punch respectively.
Further, in step 4 by the way of argon arc welding welding diaphragm steam output side weld seam.
Further, centering partition center of gravity in step 5, with cushion block by the partition inner ring and partition outer ring of partition lagging edge
Difference in height filling-in guarantees that flatness complies with standard；Every half block partition is evenly arranged 5~8 cushion blocks, and cushion block point is welded in partition
On ring.
Further, in step 6 by the way of argon arc welding welding diaphragm steam admission side weld seam, partition integral solder sequence
The quadrant area symmetrical wheel flow point group welding divided when by assembly, weld seam remain downhand position.
The beneficial effects of the present invention are: the present invention is easy to use, practical, location control is accurate, weld industry
The features such as being obviously improved.The present invention effectively controls the inner and outer ring difference in height after the welding of low pressure ring type partition, and partition is effectively prevent to close
Axial direction after half is ground one's teeth, to improve partition quality.
