I-Liebherr excavator iinxalenye ze-electromagnetic valve coil

Umgaqo wokusebenza we-solenoid valve coil

I-1.I-Inductance ibhekisela kwi-alternating magnetic flux ngaphakathi kunye nokujikeleza umqhubi xa umqhubi edlula kwi-contact current current, kunye nomlinganiselo we-magnetic flux ye-conductor kwi-current with this magnetic flux.

2.Xa i-inductor idlula kwi-DC yangoku, ngokude nje imigca yemagnethi ejikelezayo ilungisiwe, ayiyi kutshintsha ngexesha; Kodwa xa ikhoyili ye-electromagnetic idlula kunxibelelwano lwangoku, imigca yemagnethi iya kutshintsha ngokuhamba kwexesha. Ngokutsho kweFaradi's electromagnetic induction law-magnetic energy analysis, imigca yemagnethi etshintshileyo ibangela amandla kumacala omabini ekhoyili, elingana "nombane omtsha". Xa i-circuit evaliweyo isenzeka, i-induced potential i-induced current. Ngokomthetho we-Leng Ci, ukuguqulwa kwemigca yamandla yamagnetic yasekuqaleni kufuneka kugwenywe ngokusemandleni. Ngenxa yokuba utshintsho lwemigca yamandla yamagnetic yasekuqaleni luvela ekutshintsheni ukunikezelwa kwamandla okutshintshana kwangaphandle, ukusuka kwisiphumo senjongo, i-coil inductance inempawu yokuphepha ukuguqulwa kwangoku kwisiphaluka sonxibelelwano. Ikhoyili ye-inductive ineempawu ezifanayo kwi-inertia yomatshini, kwaye ibizwa ngokuba yi-"self-induction" kumbane. Ngokuqhelekileyo, xa utshintsho lwemela luvuliwe okanye lucinyiwe, iintlantsi ziya kwenzeka, ezibangelwa amandla anamandla okwenza i-self-induction phenomenon.

3.Ngelizwi, xa i-valve ye-solenoid coil ifumana umbane wonxibelelwano, imigca yamagnetic kwikhoyili iya kutshintsha kunye nokutshintshwa kwangoku, okukhokelela ekufakweni kwe-electromagnetic okuqhubekayo kwikhoyili. Oku kunokwenzeka okubangelwa utshintsho lwangoku lwekhoyili ngokwayo kuthiwa "i-self-induced electromotive force".

4.Kungabonwa ukuba i-inductance ihambelana kuphela nenani, ubungakanani, imilo kunye ne-medium coil, eyi-inertia ye-coil inductance kwaye ayinanto yakwenza nombane wangaphandle.
