Description
Technical field
The utility model relates to turbine steam seal low-lying area nest fields of measurement, and in particular to a kind of nest measurement in turbine steam seal low-lying area is auxiliary
Assistant engineer's tool.
Background technique
Cylinder groove is exactly in cylinder design, in order to install packing box, partition/fixed blade ring in cylinder（Or diaphragm housing ring/
Stationary blade carrier）And the components such as shroud packing, and the annular technical face processed is designed on cylinder block.
Since steam turbine is in overhaul, after the components such as packing box, partition, diaphragm housing ring for being installed on cylinder of dismantling, in cylinder just
Only in this way one of semi-circular as mountain depression（The other half is in casing top half）Annular technical face.
Cylinder groove is due to being designed for installation cylinder through-flow system component, and size design is accurate, processing technology is smart
Good, processing dimension control is stringent, and therefore, in steam turbine installation and overhaul, cylinder groove can be used as cylinder block positioning, cylinder
Interior each component（Set）The datum level of positioning, packing low-lying area nest refer to the inner circle of packing, two halves above and below point.There is a steam turbine maintenance measurement
Adjusted iterm adjusts packing low-lying area nest center measurement, that is to say, that measure first in the nest of packing low-lying area in installation or before filling packing
The heart know it is no meet technical requirements, if overproof will be adjusted, labyrinth casing low-lying area nest（Inner arc）Center and cylinder groove center are protected
It holds with one heart, just can guarantee when gap adjusts between packing and axis there is enough adjustment amounts.
Measurement, the adjusting and optimizing analysis of turbine steam seal radial clearance are a complexity and larger workload in service work
Work.The quality of the measurement of packing radial clearance and adjustment work, directly affects the thermal efficiency of steam turbine.If high, middle last item envelope
Gap is big, and shaft gland steam leakage just will increase, and also will cause Tubine Oil Mixed with Water.If low pressure shaft seal gap is big, vacuum system
Tightness will reduce, if diaphragm gland and flow passage clearance are big, stage efficiency will be reduced, and influence steamer to a certain extent
The economical operation of machine.If labyrinth clearance is too small, dynamic and static touch rubs and keeps unit vibration excessive when unit may be made to run, when serious
It will cause permanent bending of rotor, to influence unit safety operation.Therefore, this problem is solved in maintenance, needed between packing
Gap adjustment optimizes analysis.
Summary of the invention
In order to solve the above-mentioned technical problem, the utility model proposes a kind of turbine steam seal low-lying area nests to measure auxiliary tool,
Design is simple, easy to use.
The technical solution of the utility model：
Turbine steam seal low-lying area nest measure auxiliary tool, it include up and down adjustment bolt, locking nut, adjustment block, straight pin,
Chassis, left and right adjusting bolt, supporting block, position-limited wheel, side dress is there are two supporting block above chassis, among two supporting blocks respectively
It is provided with pin hole, adjustment block lower end is provided with circular hole, and adjustment block upper end is provided with wire hole, and vertical wire hole is provided among adjustment block, adjusts
Block lower end is rotated two supporting blocks of connection by straight pin across the circular hole of the pin hole of supporting block and adjustment block, adjustment block
Upper end wire hole is provided with left and right adjustment bolt, and left and right adjustment bolt side is equipped with position-limited wheel, vertical wire hole inward turning among adjustment block
Turn equipped with locking nut is equipped on up and down adjustment bolt and up and down adjustment bolt, locking nut is located above adjustment block.
Fixation hole there are four being opened on the chassis.
The design of the advantages of the utility model is simple, easy to use, and for fixing steel wire, auxiliary adjustment steel wire position makes steel
Silk is tightened, subsidiary, is improved accurate.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the top view of the utility model.

7, pin hole is had among two supporting blocks 7, and 3 lower end of adjustment block is provided with circular hole, and 3 upper end of adjustment block is provided with wire hole, adjustment
Vertical wire hole is provided among block 3,3 lower end of adjustment block passes through the pin hole of supporting block 7 and the circular hole of adjustment block 3 by straight pin 4
Between rotation two supporting blocks 7 of connection, 3 upper end wire hole of adjustment block is provided with left and right adjustment bolt 6,6 side of left and right adjustment bolt
Equipped with position-limited wheel 8, rotation is equipped on up and down adjustment bolt 1 and up and down adjustment bolt 1 equipped with lock in vertical wire hole among adjustment block 3
Tight nut 2, locking nut 2 are located above adjustment block 3.
Fixation hole there are four being opened on the chassis 5.
Working principle：Judge whether outside micrometer connects with steel wire using the current sound that the contact of DC current two-stage issues
Touching, is more accurately measured work by gentle touchdown.
Use operation：
1, it will be respectively fixed with the utility model tool on end face among bearing housing two sides, and chassis is fixed on end
On face.
2, it by steel wire around the position-limited wheel across two sides, and is fixed between 2 position-limited wheels and exceptionally straight.
3, the power supply line of 20 meters an or so length is selected, centre is fixedly connected with 7# battery.
4, power lead one end is fixedly connected with steel wire end, other end connecting external diameter micrometer.
5, first both ends axle envelope low-lying area nest center is found out, and makes steel wire position be axis by the adjustment of above and below position-limited wheel or left and right
Seal hollow nest center；The left-right position that left and right adjusting bolt adjusts steel wire is adjusted, up and down adjustment bolt is adjusted and adjusts steel wire
Upper and lower position.
6, other hollow nest centers are found by this steel wire position（Such as：High pressure steam discharge guide ring center, gap bridge vapour
Envelope center, middle pressure holding ring center etc.）, to make the center of entire shafting in a straight line.
