Muaj kev paub uas cov neeg siv lub tshuab ua pa yuav tsum paub!

 

Cov kabmob radial ntawm cov pa turbine tau muab faib ua ob pawg:cov bearings ruaj khov thiab cov tilting pad bearings.

 

1. Cov kabmob ruaj khov

 

Cov kabmob ruaj khov, cov kabmob roj cylindrical, cov kabmob elliptical, cov roj ntau wedges thiab cov kabmob ntau nplooj (tsis siv dav tam sim no).

 

Ib qho cylindrical bearing ib txwm muaj, muaj ib nrab sab saud thiab ib nrab sab hauv qab. Lub voj voog sab nraud ntawm lub cev qis ib nrab bearing muaj peb lub radial adjustment cushion blocks, thiab sab saum toj ntawm ib nrab sab saud bearing muaj ib lub radial adjustment cushion block rau kev hloov kho bearing.

 

Nws yog rau kev kho qhov bearing.

 

Lub elliptical bearing yog ib qho kev coj tus kheej, uas muaj qhov zoo ntawm kev muaj tsawg dua cov khaubncaws sab nraud povtseg hauv cov qauv, thiab cov babbitt alloy yog nchuav ncaj qha rau ntawm qhov chaw sab hauv ntawm cov kabmob, thiab qhov chaw sab hauv ntawm cov kabmob yog ua tiav rau hauv daim ntawv elliptical.

 

2. Tilt pad bearing

 

Plaub lub tilting pad bearings, nyob rau sab nraub qaum ntawm ib nrab sab saud ntawm ob lub pads, muaj cov springs ntawm qhov roj tawm raws li lub kauj tsheb, yog li ntawd cov pads muaj qhov nyiam nias rau lub rotor hauv sab nraub qaum no, tiv thaiv sab roj nkag ntawm lub pad thiab lub ncej journal los ntawm kev nres qhov tsis zoo, thiab tib lub sijhawm kho qhov nqes hav ntawm sab roj nkag ntawm qhov chaw pobzeb, yog li ntawd kom cov roj lubricating nkag mus rau hauv qhov chaw pobzeb.

 

Ib nrab sab saud yog lub ncoo puag ncig, thiab ib nrab qis yog tsim los ntawm ob lub tilting pad bearings, qhov ruaj khov ntawm cov bearings ntawm cov qauv no muaj zog dua li ntawm cov cylindrical bearings, thiab lub peev xwm bearing loj dua li ntawm cov tilting pad bearings dav dav, thiab nws muaj qhov zoo ntawm tilting pad bearings rau eccentricity thiab misalignment rhiab heev rau kev qhia me me.

 

Tam sim no, hom tshiab ntawm cov pobzeb uas muaj roj nkag nrog cov roj nkag qhov groove uas tig tau, cov roj nplua nyeem los ntawm kev xa roj ncaj qha thiab tso roj tawm. Txhua lub pobzeb muaj cov roj nkag qhov groove, thiab cov roj nplua nyeem raug tso tawm ncaj qha tom qab cov pobzeb ua haujlwm, uas siv hluav taws xob me me.

 

Kev faib tawm ntawmcov kabmob thawb

 

1. Radial thrust ua ke bearing

 

Cov qauv no yog tus cwj pwm los ntawm cov radial thiab thrust bearings muab tso rau hauv ib lub cev, thiab qhov sib npaug ntawm lub cev bearing thiab lub tes tsho bearing, yog li ntawd cov bearing tau hloov kho nrog qhov deflection deformation ntawm lub ncej, yog li ntawd muaj kev sib cuag zoo ntawm qhov chaw pad thiab qhov chaw thrust phaj ntawm lub rotor, thiab cov qauv no yog tsim rau chav tsev nrog rotor hloov pauv tau thiab axial load tsis loj dhau.

 

Kuj tseem muaj ib hom radial thrust combined bearing rau elastic balanced pads, thrust pads raug so ntawm lub nplhaib elastic, thiab lub nplhaib elastic tsim cov elastic deformation thaum bearing, yog li ua tau raws li qhov yuav tsum tau ua kom txhua qhov chaw ntawm cov pobzeb muaj kev sib cuag zoo nrog lub phaj thrust. Cov qauv no yog siv rau hauv cov chav tsev nrog cov rotors nruj thiab cov khoom thauj axial qis.

 

2.Kingsbury thrust bearings

 

Cov pobzeb yog symmetrically txhawb nqa thiab siv tau rau ob qho tib si zoo thiab tsis zoo steering ua haujlwm.
