Excavator E330D E336D Hydraulic Direction Solenoid Valve Coil

Coil txoj cai

1.Inductance yog qhov piv ntawm alternating magnetic flux generated nyob rau hauv thiab ib ncig ntawm tus neeg xyuas pib thaum alternating tam sim no dhau los ntawm tus neeg xyuas pib, thiab cov hlau nplaum flux ntawm tus neeg xyuas pib mus rau tam sim no uas tsim cov magnetic flux.

2.Thaum DC tam sim no dhau los ntawm qhov inductor, tsuas yog ib kab hlau nplaum ruaj khov tshwm nyob ib puag ncig nws, uas tsis hloov nrog lub sijhawm;Txawm li cas los xij, thaum alternating tam sim no dhau los ntawm lub kauj, cov kab hlau nplaum nyob ib puag ncig nws yuav hloov nrog lub sijhawm.Raws li Faraday txoj cai ntawm electromagnetic induction-magnetic induction, hloov magnetic teb kab yuav tsim ib tug induced muaj peev xwm ntawm ob kawg ntawm lub kauj, uas yog sib npaug rau ib tug "tshiab fais fab mov".Thaum lub voj kaw raug tsim, qhov kev tsim muaj peev xwm ua rau muaj qhov cuam tshuam tam sim no.Raws li Lenz txoj cai, tag nrho cov nyiaj ntawm cov kab hlau nplaum tsim los ntawm kev ntxias tam sim no yuav tsum sim tiv thaiv qhov kev hloov ntawm cov kab hlau nplaum qub.Vim hais tias thawj qhov kev hloov pauv ntawm cov kab hlau nplaum sib nqus los ntawm kev hloov pauv ntawm cov khoom siv hluav taws xob sab nraud, los ntawm cov txiaj ntsig ntawm lub hom phiaj, qhov inductance coil muaj cov yam ntxwv ntawm kev tiv thaiv kev hloov pauv tam sim no hauv AC Circuit Court.Inductive coil muaj cov yam ntxwv zoo sib xws rau inertia hauv mechanics, thiab nws yog lub npe hu ua "self-induction" hauv hluav taws xob.Feem ntau, sparks yuav tshwm sim nyob rau lub sijhawm thaum lub riam hloov yog qhib los yog tawm, uas yog tshwm sim los ntawm lub siab induced muaj peev xwm tshwm sim los ntawm tus kheej-induction phenomenon.

3.Nyob rau hauv ib lo lus, thaum lub inductance coil txuas nrog AC fais fab mov, cov kab hlau nplaum hauv lub kauj yuav hloov txhua lub sijhawm nrog rau qhov sib hloov tam sim no, uas ua rau lub tshuab hluav taws xob txuas ntxiv ntawm lub kauj.Qhov no electromotive quab yuam generated los ntawm kev hloov ntawm tam sim no ntawm lub kauj nws tus kheej yog hu ua "tus kheej-induced electromotive quab yuam".

4.Nws tuaj yeem pom tau tias qhov inductance tsuas yog ib qho parameter uas muaj feem xyuam nrog cov lej ntawm cov lem, qhov loj, cov duab thiab nruab nrab ntawm cov kauj.Nws yog ib qho kev ntsuas ntawm inertia ntawm lub inductance coil thiab tsis muaj dab tsi cuam tshuam nrog cov ntawv thov tam sim no.
