Sib nqus couplings yog cov tsis sib txuas uas siv cov hlau nplaum sib nqus los hloov lub zog, quab yuam lossis txav los ntawm ib tus tswvcuab tig mus rau lwm tus.Kev hloov pauv yuav tshwm sim los ntawm qhov tsis muaj qhov sib nqus thaiv qhov thaiv tsis muaj kev sib txuas ntawm lub cev.Cov couplings yog opposing khub ntawm discs los yog rotors embedded nrog hlau nplaum.
Kev siv cov hlau nplaum sib txuas hnub rov qab mus rau qhov kev sim ua tiav los ntawm Nikola Tesla thaum xyoo pua 19th.Tesla wirelessly lit teeb siv ze-tsav resonant inductive coupling.Scotland physicist thiab engineer Sir Alfred Ewing ntxiv cov kev xav ntawm magnetic induction nyob rau hauv thaum ntxov 20th caug xyoo.Qhov no tau coj mus rau kev txhim kho ntawm ntau cov thev naus laus zis uas siv cov hlau nplaum sib txuas.Sib nqus couplings nyob rau hauv daim ntawv thov uas yuav tsum tau muaj meej heev thiab muaj zog ua hauj lwm tau tshwm sim nyob rau hauv ib nrab xyoo pua dhau los.Kev loj hlob ntawm cov txheej txheem tsim khoom siab heev thiab qhov muaj ntau ntxiv ntawm cov khoom siv hlau nplaum tsawg hauv ntiaj teb ua rau qhov no ua tau.
Thaum tag nrho cov hlau nplaum sib txuas siv tib lub zog sib nqus thiab cov cuab yeej siv zog yooj yim, muaj ob hom sib txawv los ntawm kev tsim.
Ob hom tseem ceeb suav nrog:
-Disc-hom couplings featuring ob lub ntsej muag-rau-lub ntsej muag disc halves embedded nrog ib tug series ntawm hlau nplaum qhov twg torque yog kis thoob plaws qhov sib txawv ntawm ib tug disc mus rau lwm yam.
-Synchronous-type couplings xws li cov hlau nplaum tas mus li, coaxial couplings thiab rotor couplings qhov twg lub rotor sab hauv yog ze rau sab hauv ntawm lub rotor sab nraud thiab cov hlau nplaum tas mus li hloov torque ntawm ib lub rotor mus rau lwm qhov.
Ntxiv rau ob hom tseem ceeb, sib nqus couplings suav nrog spherical, eccentric, kauv thiab nonlinear tsim.Cov kev sib nqus sib nqus sib txuas no pab rau kev siv lub zog thiab kev co, tshwj xeeb yog siv rau hauv kev siv biology, chemistry, quantum mechanics, thiab hydraulics.
Hauv cov ntsiab lus yooj yim tshaj plaws, cov hlau nplaum sib txuas ua haujlwm siv lub tswv yim tseem ceeb uas cov hlau nplaum sib nqus nyiam.Lub attraction ntawm cov hlau nplaum kis torque los ntawm ib tug magnetized hub mus rau lwm tus (los ntawm tus tsav tsheb ntawm lub coupling mus rau tus neeg tsav tsheb).Torque piav txog lub zog uas tig ib yam khoom.Raws li sab nraud angular momentum yog siv rau ib lub hub sib nqus, nws tsav lwm tus los ntawm kev xa cov torque magnetically ntawm qhov chaw los yog los ntawm ib qho kev thaiv tsis sib nqus xws li phab ntsa sib faib.
Tus nqi ntawm torque generated los ntawm cov txheej txheem no yog txiav txim los ntawm cov variables xws li:
- Ua haujlwm kub
- Ib puag ncig hauv kev ua haujlwm tshwm sim
-Magnetic polarization
- Tus lej ntawm tus ncej khub
-Dimensions ntawm ncej khub, nrog rau qhov sib txawv, txoj kab uas hla thiab qhov siab
-Cov txheeb ze angular offset ntawm khub
- Hloov ntawm cov khub
Nyob ntawm qhov sib txawv ntawm cov hlau nplaum thiab cov discs lossis rotors, cov hlau nplaum polarization yog radial, tangential lossis axial.Tom qab ntawd torque hloov mus rau ib qho lossis ntau qhov txav mus.
Sib nqus couplings yog suav tias yog superior rau cov tsoos mechanical couplings nyob rau hauv ntau txoj kev.
Tsis muaj kev sib cuag nrog cov khoom txav:
- Txo kev sib txhuam
- Ua kom muaj cua sov tsawg
-Ua siab tshaj plaws siv lub zog tsim
-Ua kom tsis txhob hnav thiab tsim kua muag
- Ua tsis muaj suab nrov
- Tshem tawm qhov xav tau ntawm lubrication
Tsis tas li ntawd, cov qauv tsim muaj feem cuam tshuam nrog cov hom synchronous tshwj xeeb tso cai rau cov hlau nplaum sib nqus los ua cov ntaub ntawv pov thawj, dej-pov thawj thiab xeb-pov thawj.Cov khoom siv yog corrosion resistant thiab engineered los lis kev khiav hauj lwm ib puag ncig.Lwm qhov txiaj ntsig yog qhov sib nqus sib nqus uas tsim kom muaj kev sib haum xeeb rau kev siv hauv thaj chaw uas muaj peev xwm cuam tshuam.Tsis tas li ntawd, cov khoom siv sib nqus couplings yog tus nqi ntau dua li cov khoom siv sib txuas thaum nyob hauv thaj chaw uas muaj kev txwv tsis pub siv.Sib nqus couplings yog ib qho kev xaiv nrov rau kev sim thiab kev teeb tsa ib ntus.
Sib nqus couplings muaj txiaj ntsig zoo thiab ua haujlwm zoo rau ntau daim ntawv thov saum toj no suav nrog:
- Neeg hlau
- Tshuaj engineering
- Cov cuab yeej kho mob
- Tshuab installation
- Kev ua zaub mov
-Rotary tshuab
Tam sim no, sib nqus couplings yog khoom plig rau lawv cov kev ua tau zoo thaum submerged hauv dej.Cov motors encased nyob rau hauv ib tug uas tsis yog-magnetic barrier nyob rau hauv cov kua twj tso kua mis thiab propeller systems cia lub magnetic quab yuam ua hauj lwm lub kiv cua los yog qhov chaw ntawm lub twj tso kua mis nyob rau hauv kev sib cuag nrog cov kua.Dej ncej tsis ua hauj lwm tshwm sim los ntawm kev ntxeem tau ntawm cov dej nyob rau hauv lub cev muaj zog vaj tse yog zam los ntawm spinning ib txheej ntawm hlau nplaum nyob rau hauv ib lub thawv kaw.
Cov kev siv hauv qab dej muaj xws li:
-Diver propulsion tsheb
-Aquarium twj tso kua mis
- Cov tsheb thauj mus los hauv qab dej nyob deb
Raws li thev naus laus zis txhim kho, sib nqus couplings tau dhau los ua qhov hloov pauv rau kev hloov pauv ceev hauv cov twj thiab kiv cua.Ib qho piv txwv ntawm kev siv tseem ceeb hauv kev lag luam yog cov motors hauv cov cua turbines loj.
Tus naj npawb, qhov loj me thiab hom hlau nplaum siv nyob rau hauv ib qho kev sib txuas nrog rau qhov sib thooj torque uas ua tau yog qhov tseem ceeb tshwj xeeb.
Lwm yam specifications muaj xws li:
-Lub xub ntiag ntawm ib tug barrier ntawm cov sib nqus khub, tsim nyog lub apparatus rau submersion nyob rau hauv dej
-Magnetic polarization
-Tus naj npawb ntawm cov khoom txav torque yog pauv cov hlau nplaum
Cov hlau nplaum uas siv hauv cov hlau nplaum sib txuas ua ke ntawm cov ntaub ntawv tsis tshua muaj hauv ntiaj teb xws li neodymium hlau boron lossis samarium cobalt.Cov teeb meem uas muaj nyob nruab nrab ntawm cov khub sib nqus yog ua los ntawm cov khoom tsis sib nqus.Piv txwv ntawm cov ntaub ntawv uas tsis nyiam los ntawm cov hlau nplaum yog stainless hlau, titanium, yas, iav thiab fiberglass.Cov seem ntawm cov khoom txuas nrog rau ob sab ntawm cov hlau nplaum sib nqus yog zoo ib yam rau cov siv hauv txhua qhov system nrog cov khoom siv kho tshuab ib txwm siv.
Qhov raug sib nqus sib nqus yuav tsum ua kom tau raws li qhov xav tau ntawm torque uas tau teev tseg rau kev ua haujlwm.Yav dhau los, lub zog ntawm cov hlau nplaum yog qhov txwv.Txawm li cas los xij, kev tshawb pom thiab muaj ntau ntxiv ntawm cov hlau nplaum tshwj xeeb hauv ntiaj teb yog qhov muaj peev xwm loj hlob sai ntawm cov hlau nplaum sib txuas.
Ib qho kev xav thib ob yog qhov tsim nyog ntawm cov couplings yuav tsum yog ib nrab lossis tag nrho hauv dej los yog lwm yam kua.Sib nqus coupling manufacturers muab cov kev pabcuam customization rau cov kev xav tau tshwj xeeb thiab muaj zog.
