Ingakanani ixesha elilindelekileyo le-solenoid coil kwinkonzo yangaphandle eqhubekayo?
Ikhoyili ye-solenoid esemgangathweni elinganiswe umsebenzi wokunkcenkceshela ngaphandle kufuneka ihlale iminyaka emihlanu ukuya kwelishumi phantsi kweemeko zokusebenza eziqhelekileyo. Nangona kunjalo, ubushushu obugqithisileyo, ukuvezwa yi-UV, ukungena komswakama, kunye nokuguquguquka kombane kunokunciphisa ubomi bexesha elide kakhulu. Iikhoyili ezisebenza kufutshane nombane wazo ophezulu zishushu kwaye ziwohloka ngokukhawuleza, ngelixa iimeko ze-under-voltage zibangela ukuba i-plunger ithethe kwaye igubungele ii-coil windings ngoomatshini. Kwiindawo ezikunxweme okanye ezinomswakama ophezulu, ukufuma kunokungena kwi-potting compound eqhekekileyo kwaye kubangele ii-internal short circuits. Ukuhlolwa rhoqo kwe-coil housing rhoqo ukuze kubonwe iintanda, iimpawu zokutsha, okanye ukutshintsha kombala kunceda ukuchonga iikhoyili ezisondela ekupheleni kobomi ngaphambi kokuba zingasebenzi ebaleni.
Ndingayisebenzisa i-solenoid ye-24VDC kwisilawuli sokunkcenkceshela se-24VAC?
Ngokubanzi, akufuneki udibanise ii-solenoids ze-AC kunye ne-DC kunye nezilawuli ngaphandle kokuba umenzi uchaza ngokucacileyo ukuhambelana. I-solenoid ye-24VDC eqhagamshelwe kwisilawuli se-24VAC inokutshisa kakhulu kuba i-AC waveform ivelisa i-eddy currents kwi-solid steel plunger, ivelise ubushushu obugqithisileyo obunokutshabalalisa i-coil insulation. Ngokwahlukileyo koko, i-solenoid ye-24VAC kwi-DC supply iya kutsala umbane omninzi kunokuba bekucwangcisiwe kuba i-coil impedance iphantsi ngaphandle kwe-inductive reactance ekhoyo ekusebenzeni kwe-AC. Ezinye ii-solenoids zoomatshini zanamhlanje, ezifana ne- I-3W-24VAC/24VDC Mechanical Solenoid, zenzelwe ukwamkela nayiphi na i-waveform ngokukhuselekileyo. Soloko uqinisekisa umlinganiselo we-voltage kunye nohlobo lwangoku oluprintiweyo kwi-coil housing ngaphambi kokufakela ukuze ungonakalisi i-component.
Kufuneka zihlolwe kangaphi iivalvu ze-solenoid ze-commercial landscape?
Kwiindawo zorhwebo, uvavanyo olupheleleyo lwevalvu ye-solenoid kufuneka lwenzeke ubuncinane kabini ngonyaka, ngokugqibeleleyo ekuqaleni nasekupheleni kwexesha lokunkcenkceshela eliphambili. Uhlolo ngalunye kufuneka luquke ukulinganisa i-voltage kwi-valve terminals, ukujonga umonakalo obonakalayo we-coil, ukuqinisekisa ukuba i-manual bleed screw isebenza ngokukhululekileyo, kunye nokuqinisekisa ukuba indawo nganye iyavula kwaye ivale ngexesha elilindelekileyo. Kwimimandla enamanzi aqinileyo okanye umhlaba onesihlabathi, uhlolo lwekota luyacetyiswa kuba ukwakheka kwezimbiwa kunye nokuqokelelwa kwedaka kwenzeka ngokukhawuleza. Ukugcina irekhodi yolondolozo kunye nokufundwa kwe-voltage kutyelelo ngalunye kunceda iingcali zibone iindlela zokuwohloka kancinci kancinci ngaphambi kokuba zibe ziintsali ezipheleleyo zentsimi.
