Description
Technical field
The present invention relates to Steam Turbine Field dynamic balancing commissioning devices, specifically a kind of Steam Turbine Field dynamic balancing channel
Device.
Background technology
Turbo-generator Set is always Turbo-generator Set as a kind of high-speed rotating turbomachinery, shafting vibration problem
A kind of common failure, and spot dynamic balance is then a kind of common method for solving the problems, such as shafting vibration.
According to the operation principle of steam turbine, Steam Turbine in the operating condition its low pressure condenser need to ensure it is higher true
Sky, it is in order to be quickly cooled down unit and quickly start after compressor emergency shutdown, and unit is through-flow, and inside still needs to ensure vacuum
State.Traditional Steam Turbine spot dynamic balance flow is typically：Shutdown-jiggering-destruction vacuum-adjustment balance weight-pumping
Vacuum-opens machine, it will and the vacuum of unit is destroyed, and destroys before vacuum can cause unit to open machine again and needs to vacuumize again, shadow
It rings unit and opens the machine time.
Invention content
The purpose of the present invention is to solve above-mentioned technical problems, provide a kind of Steam Turbine Field dynamic balancing lane device,
Shafting dynamic balance is carried out in the case of capable of not destroying vacuum after a shutdown using the device, unit opens at once after the completion of dynamic balancing
Machine, highly shortened unit opens the machine time.
Realize the technical scheme is that：A kind of Steam Turbine Field dynamic balancing lane device, it is characterised in that：Including spiral shell
Line pull rod, handle, passage cover plate, channel annulus and sealant；The channel annulus in cylinder inner close fitting cylinder wall, upper part with
Passage cover plate connects, and its underpart is equipped with sealant, and sealant can seal after being compressed with rotor cylinder surface；The channel
Cover board is connect with thread；The thread is pierced by cylinder flange lid, and top is connect with handle；The channel annulus energy
It is moved up and down in cylinder；The thread, handle, passage cover plate and cylinder flange lid can be dismantled.
There is feather key in the passage cover plate side, which is embedded in the guide groove on cylinder wall.
The cylinder is equipped with circumferential seal circle on the contact surface of channel annulus.
The circumferential seal circle is preferably three.
The thread is threadedly coupled by cylinder flange lid center thread through hole with cylinder flange lid, and the two being capable of phase
To movement.
The sealant is softer metals.
The passage cover plate is connect by cover board above with thread；The cover board will penetrate thread therein
The disk of bottom is limited in the space between cover board and passage cover plate.
The beneficial effects of the invention are as follows：
Through the invention, Balancing of Steam Turbine Shaft is ensureing at the scene into being just not necessarily to destroy the vacuum of unit when action balance
Into the dismounting of action balance screw in the case of unit vacuum, machine red switch, nothing can be directly opened after the completion of the dismounting of dynamic balancing screw
It need to vacuumize, reduce the start and stop interval time of unit.

Specific implementation mode
As shown in Figure 1：A kind of Steam Turbine Field dynamic balancing lane device, including thread 1, handle 2, passage cover plate
8, channel annulus 9 and sealant 10；The channel annulus 9 is connect in 5 inner close fitting cylinder wall of cylinder, upper part with passage cover plate 8,
Its underpart is equipped with sealant 10；The passage cover plate 8 is connect by cover board 3 above with thread 1, and the cover board 3 will
The disk 11 for penetrating 1 bottom of thread therein is limited in the space between cover board 3 and passage cover plate 8.The screw thread is drawn
Bar 1 is pierced by cylinder flange lid 4, and top is connect with handle 2；The channel annulus 9 can move up and down in cylinder 5；The spiral shell
Line pull rod 1, handle 2, passage cover plate 8 and cylinder flange lid 4 can be dismantled.There is feather key 6 in 8 side of the passage cover plate, this is led
It is embedded in the guide groove 14 on cylinder wall to key 6, ensures that channel annulus 9 can vertically move.The cylinder 5 and channel annulus 9
On contact surface, there are three circumferential seal circles 7 for installation.The thread 1 passes through 4 center thread through hole of cylinder flange lid and cylinder
Blind flange 4 is threadedly coupled, and the two can relatively move.The sealant 10 is softer metals, with 12 cylinder face pressure of rotor
It is next to seal.
As shown in Figure 2：The Steam Turbine Field dynamic balancing lane device is mounted on steam turbine 5, unit normal operation
When, thread 1, handle 2 and cover board 3 are disassembled, channel annulus 9 is risen into topmost, does not influence the normal work of rotor 12.
As shown in Figure 3：When turbine shafting need carry out spot dynamic balance, increase dynamic balancing on turbine rotor 12
When screw 13, push channel annulus 9 and sealant 10 to turbine rotor 12, dynamic balancing with handle 2 by rotating thread 1
Lane device is adjacent to rotor 12.
As shown in Figure 4：After dynamic balancing lane device and rotor 12 are adjacent to, thread 1, handle 2, cover board are removed
3, cylinder flange lid 4, feather key 6, passage cover plate 8, you can in the case where ensureing steam turbine inner vacuum into action balance spiral shell
The dismounting of nail 13.Dynamic balancing screw 13 can directly open machine red switch after the completion of dismounting, and without vacuumizing, reduce the start and stop of unit
Machine interval time.
Use above specific case is illustrated the present invention, is merely used to help understand the present invention, not limiting
The system present invention.For those skilled in the art, according to the thought of the present invention, can also make several simple
It deduces, deform or replaces.
