Yuav Ua Li Cas Teeb Kev Tiv Thaiv Qhov Tseem Ceeb Ntawm Hnyav Load Thiab Lub Teeb Load Ntawm Lub Tsav? Tom qab nyeem nws, koj yuav nkag siab

Yuav ua li cas los teeb tsa kev tiv thaiv qhov tseem ceeb ntawm qhov hnyav thiab lub teeb ntawm lub cev muaj zog? Tom qab nyeem nws, koj yuav nkag siab

Ob peb xyoos dhau los, kuv pom ib tug engineer solemnly qhia nws subordinates kom teem lub overload tiv thaiv tsis raws li qhov pib load ntawm peb-theem asynchronous lub cev muaj zog, thiab yuav tsum to taub seb lub cev muaj zog yog lub teeb load pib los yog hnyav load pib, txwv tsis pub ib yam dab tsi yuav tshwm sim, vim hais tias lub load hnyav pib tam sim no yuav loj heev.

Lub sijhawm ntawd, kuv xav taw qhia rau nws tias qhov no yog kev nkag siab yuam kev, tab sis kuv ntshai tsam cov neeg ua txhaum, tab sis tom qab ntawd kuv pom tias muaj ntau tus engineers hluav taws xob niaj hnub no muaj kev nkag siab tsis zoo, kuv yeej tsis paub tias lawv kawm tau li cas hauv tsev kawm, qhov tseeb, lawv yuav tsis nyob hauv qhov loj no.

Qhov tseeb, qhov tsis muaj-load, lub teeb-load, thiab hnyav-lub luag haujlwm pib tam sim no ntawm peb-theem asynchronous motors yog tib yam, thiab kev tiv thaiv kev tiv thaiv overload tsis tuaj yeem hloov kho arbitrarily. Vim tias qhov pib torque logic ntawm lub cev muaj zog zoo li no: Kuv=Kmdblcos Rau lub cev muaj zog, cov qauv tsis tu ncua Km, sib nqus flux d, thiab lub zog hluav taws xob cosφ yog tsau, yog li qhov pib tam sim no kuv yuav tsis hloov, tab sis lub sij hawm pib yuav txawv, lub teeb load pib lub sij hawm luv luv, thiab hnyav load pib lub sij hawm ntev.

Tus phooj ywg: Lub rooj zaum tam sim no ntawm lub cev muaj zog yog tsau, tab sis qhov nkhaus ntawm lub cev muaj zog los ntawm kev thaiv mus rau qhov kev hloov pauv ntawm tus qauv qub yog qhov sib txawv ntawm qhov hnyav pib (xws li kiv cua thiab siv conveyors, thiab lwm yam) thiab lub teeb load pib (xws li centrifugal twj tso kua mis, thiab lwm yam), uas yog, lub sij hawm pib tsis zoo li qub.

Kev tiv thaiv lub cev muaj zog yuav tsum yog raws li tus nqi tam sim no ntawm lub cev muaj zog los teeb tsa tus nqi tiv thaiv, kev tiv thaiv hluav taws xob tuaj yeem ua raws li cov yam ntxwv ntawm kev thauj khoom, teeb lub sijhawm pib thiab lwm yam kev tiv thaiv, thermal relay tiv thaiv tus nqi ruaj khov, yog tias muaj cov khoom siv ntsuas, nws yog qhov zoo tshaj plaws los siv cov cuab yeej ntsuas tawm ntawm lub tshuab los kho kom zoo, thiab tom qab ntawd nruab thiab muab tso rau hauv kev ua haujlwm, qhov chaw kuaj yuav tsum zoo ib yam lossis zoo ib yam li chav ntsuas kub ntawm qhov chaw ua haujlwm.

Raws li seb puas yuav siv cov kauj ruam pib ntsuas, nws nyob ntawm kev nqa lub peev xwm ntawm lub zog hluav taws xob, piv txwv li, cov nroj tsuag loj hauv petrochemical hauv qab 180KW siv tag nrho-voltage pib.
