Abstract
The utility model discloses a kind of Steam Turbine in Fire Power Plant bearing housing annular blinker components, including three pieces blinker, washer, screw bolt and nut, the hole for being inserted in turbine shaft is provided among the blinker, the three pieces blinker is arranged above and below horizontal positioned, multiple equally distributed mounting holes are provided on the blinker, washer is equipped between two adjacent blinkers, washer is simultaneously corresponding with mounting hole, bolt is inserted into the mounting hole of blinker and tightens bolt, and three pieces blinker is made to be fixedly connected.The utility model has the advantages of simple structure, it is easy to operate, the axle envelope that blinker component makes leak steam step-by-step generate restriction effect, make the steam momentum constantly loss of leakage and loses pressure, it avoids or the axle envelope few as possible steam that leaks enters in bearing housing, also the microparticle effectively completely cut off in gland packing leakage and air enters bearing housing, to keep turbo-engine lube oil long-term qualified.
Description
Technical field
The utility model is related to the technical field of Steam Turbine in Fire Power Plant bearing housing, especially a kind of thermal power plant vapour
Turbine bearing housing annular blinker component.
Background technology
In the prior art, the gap of the annular blinker used in bearing box of steam turbine and turbine shaft is larger (between former
Gap about 4-5mm), and series is few, high intermediate pressure cylinder end side axle envelope more or less understands some steam and leaks so that steam or air
In microparticle or air in microparticle enter in bearing housing, so as to cause long-term oil mixed with water in lubricating oil, accelerate profit
Lubricating oil emulsifies.
Utility model content
The technical problems to be solved in the utility model is：In order to which solve in above-mentioned background technology of the existing technology asks
Topic, provides a kind of improved Steam Turbine in Fire Power Plant bearing housing annular blinker component.
Technical solution adopted by the utility model to solve its technical problems is：A kind of Steam Turbine in Fire Power Plant bearing housing
Annular blinker component, including three pieces blinker, washer, screw bolt and nut are provided among the blinker and are inserted in steam turbine
The hole of axis, the three pieces blinker are arranged above and below on horizontal positioned, described blinker and are provided with multiple equally distributed installations
Hole is equipped with washer between adjacent two blinkers, and washer is simultaneously corresponding with mounting hole, and bolt is inserted into the mounting hole of blinker
And bolt is tightened, so that three pieces blinker is fixedly connected.
The blinker is made of two semicircle catch.
The gap of the blinker and turbine shaft is 0.55-0.75mm.
The utility model has the beneficial effects that the utility model has the advantages of simple structure, easy to operate, blinker component makes axle envelope
The steam step-by-step that leaks generates restriction effect, makes the steam momentum constantly loss of leakage and loses pressure, avoids or axis few as possible
The steam that leaks is sealed to enter in bearing housing, the microparticle also effectively completely cut off in gland packing leakage and air enters bearing housing, to
Keep turbo-engine lube oil long-term qualified.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the vertical view of Fig. 1.
In figure：1, blinker, 2, washer, 3, bolt, 4, nut, 5, turbine shaft.
Specific implementation mode
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
As shown in Figs. 1-2, Steam Turbine in Fire Power Plant bearing housing annular blinker component, including three pieces blinker 1, washer
2, bolt 3 and nut 4, are provided with the hole for being inserted in turbine shaft 5 among blinker 1, three pieces blinker 1 be arranged above and below it is horizontal positioned,
Be provided with multiple equally distributed mounting holes on blinker 1, be equipped with washer 2 between adjacent two blinkers 1, washer 2 and with peace
Dress hole is corresponding, and bolt 3 is inserted into the mounting hole of blinker 1 and tightens bolt, and three pieces blinker 1 is made to be fixedly connected.
Blinker 1 is made of two semicircle catch, can also be to be integrally formed, the gap of blinker 1 and turbine shaft
For 0.55-0.75mm.
The quantity of blinker 1 can be increased and decreased according to actual conditions, to reach better effect.
When installation, blinker 1 adjusts the gap with turbine shaft 5, and washer 2 is placed on 1 lower section of blinker, and bolt 3 is inserted
After the mounting hole and washer that enter blinker 1, then tighten nut 4, you can use.
The use of the utility model is in unit continuous operation, without frequent starting turbo-engine lube oil filter system
System oil strain, can not only meet the requirement of Lubricating Oil Temperature, but also the quick ideal section of small investment may be implemented completely
Can lower consumption effect, at the same can also Long-time Shut-down lubricant oil filter and ensure the qualified purpose of turbo-engine lube oil.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to which its technology is determined according to right
Property range.
