Dab tsi yog qhov zoo ntawm qhov kub siab magnetic twj tso kua mis? ?

  Lub twj tso kua mis magnetic kub yog ib hom kev tsis sib cuag torque kis tau los ntawm kev sib nqus tsav (magnetic coupling), kom lub foob zoo li qub hloov lub foob dynamic, kom lub twj tso kua mis tsis muaj paug. Txij li thaum lub twj tso kua mis ncej thiab lub puab magnetic rotor raug kaw tag nrho los ntawm lub twj tso kua mis lub cev thiab lub tes tsho cais, qhov teeb meem xau tau daws tau tag nrho, thiab kev nyab xeeb ntawm cov nplaim hluav taws kub hnyiab, tawg, tshuaj lom thiab teeb meem tawm los ntawm lub twj tso kua mis foob hauv kev ua kom zoo thiab tshuaj lom neeg. kev lag luam raug tshem tawm.

Kev sib xyaw ntawm lub twj tso kua mis

Lub siab kub sib nqus twj tso kua mis muaj peb ntu: tus kheej-priming twj tso kua mis, sib nqus tsav thiab lub cev muaj zog. Cov khoom tseem ceeb, lub tshuab sib nqus, muaj cov hlau nplaum sab nraud, ib lub tshuab magnetic sab hauv thiab lub tes tsho tsis sib nqus.

1. Cov hlau nplaum tas mus li:
Cov hlau nplaum tas mus li ua los ntawm cov ntaub ntawv muaj qhov kub thiab txias ntau yam (-45-400 ° C), siab coercive quab yuam, zoo anisotropy nyob rau hauv cov kev taw qhia ntawm lub magnetic teb, thiab tsis muaj demagnetization yuav tshwm sim thaum tib ncej nyob ze rau ib leeg. Nws yog ib yam zoo heev qhov chaw ntawm magnetic teb.

2. Lub tes tsho cais:
Thaum siv cov hlau spacer, lub spacer yog nyob rau hauv ib tug sinusoidal alternating magnetic teb, thiab ib tug eddy tam sim no yog induced nyob rau hauv ib seem perpendicular mus rau cov kev taw qhia ntawm lub magnetic quab yuam kab thiab hloov mus rau hauv tshav kub.

3. Kev tswj cov roj lubricating txias
Thaum lub twj tso kua mis magnetic kub khiav, ib qho me me ntawm cov kua yuav tsum tau siv los yaug thiab txias qhov sib txawv ntawm lub nplhaib ntawm lub puab tsaig sib nqus rotor thiab lub tes tsho cais thiab kev sib txhuam ntawm cov zawv zawg kabmob. Tus nqi ntws ntawm lub coolant feem ntau yog 2% -3% ntawm tus qauv tsim tus nqi ntawm lub twj tso kua mis, thiab lub nplhaib sib txawv thaj tsam ntawm lub puab hlau nplaum rotor thiab lub tes tsho cais ua kom muaj cua sov vim yog eddy tam sim no. Thaum cov dej txias lubricating tsis txaus los yog lub qhov dej ntws tsis zoo los yog thaiv, qhov kub ntawm qhov nruab nrab yuav siab dua qhov ua haujlwm kub ntawm cov hlau nplaum ruaj khov, yog li cov hlau nplaum sab hauv lub rotor yuav maj mam poob nws cov hlau nplaum thiab cov hlau nplaum yuav ua haujlwm. poob. Thaum qhov nruab nrab yog dej los yog dej-raws li cov kua dej, qhov kub nce hauv cheeb tsam annulus tuaj yeem tswj tau ntawm 3-5 ° C; Thaum qhov nruab nrab yog hydrocarbon lossis roj, qhov kub nce hauv thaj tsam annulus tuaj yeem khaws cia ntawm 5-8 ° C.

4. Plain bearing
Cov ntaub ntawv ntawm cov twj tso kua mis sib nqus zawv zawg bearings suav nrog impregnated graphite, ntim PTFE, engineering ceramics, thiab lwm yam. Vim tias engineering ceramics muaj cov cua sov zoo, tiv thaiv corrosion, thiab kev sib txhuam tsis kam, zawv zawg bearings ntawm cov twj sib nqus feem ntau yog ua los ntawm engineering ceramics.
Txij li thaum engineering ceramics yog nkig heev thiab muaj me me expansion coefficient, lub bearing clearance yuav tsum tsis txhob me me heev kom tsis txhob sib tsoo ncej-tuav.Vim cov zawv zawg bearings ntawm kub sib nqus twj tso kua mis yog lubricated los ntawm lub thauj nruab nrab, sib txawv cov ntaub ntawv yuav tsum tau siv rau. ua cov bearings raws li kev tshaj tawm thiab kev ua haujlwm sib txawv.
