Rexroth Futian Lovo excavator tuatahi conductive solenoid valve coil

Te kitenga porowhita

(1) I te wa e whiriwhiri ana me te whakamahi i te coil inductance

me whakaaro tuatahi tatou mo te tirotiro me te ine o te porowhita, katahi ka whakatau i te kounga o te porowhita.Kia tika ai te kite i te inductance me te kounga o te Q o te inductance coil, me tino hiahia nga taputapu motuhake, a he uaua ake te tikanga whakamatautau.I roto i nga mahi mahi, kaore i te whakahaerehia tenei momo kitenga, engari ko te tirotiro i runga-atu o te porowhita me te whakatau i te uara Q.Tuatahi, ka taea te ine i te parenga DC o te coil ma te whakamahi i te konae parenga multimeter, ka whakatauritea ki te uara parenga taketake kua whakatauhia, te uara parenga ingoa ranei.Mēnā he nui ake te uara ātete ine i te uara ātete taketake i whakatauhia, i te uara ātete whakaingoa ranei, ahakoa kare te tohu e neke (ko te uara ātete ki te infinite X), ka taea te whakatau kua pakaru te porowhita.Mena he iti rawa te parenga ine, he uaua ki te whakatairite mehemea he ara iahiko poto nui, he ara iahiko poto o te rohe.Ka puta enei ahuatanga e rua, ka taea te whakatau he kino te porowhita kaore e taea te whakamahi.Mena karekau he rerekee te parenga kitenga mai i te aatete taketake i whakatauhia, i te whakaingoa ranei, ka taea te whakatau he pai te porowhita.I roto i tenei take, ka taea e tatou te whakawa i te kounga o te coil, ara, te uara Q, i runga i nga ahuatanga e whai ake nei.Ina he rite te inductance o te coil, he iti ake te parenga DC, he teitei ake te uara Q.Ka nui ake te diameter o te waea i whakamahia, ka nui ake te uara Q;Mena ka whakamahia te awhiowhio maha, ka nui ake nga whenu o te waea, ka nui ake te uara Q;Ko te iti ake o te ngaronga o nga rawa e whakamahia ana i roto i te porowhita porowhita (he matua rino ranei), ka nui ake tona uara Q.Hei tauira, i te wa e whakamahia ana te peera rino-nui-nui hei matua rino, he nui ake te uara Q i tera i te wa e whakamahia ana te pepa rino kirikiri noa hei matua rino;Ko te iti ake o te puritanga tohatoha me te rerenga aukume o te coil, ka teitei ake tona uara Q.Hei tauira, he teitei ake te uara q o te miere miere awhiowhio i tera o te awhi papatahi me te teitei ake i tera o te awhi matapōkere;Karekau he parepare o te porowhita, karekau he waahanga whakarewa huri noa i te tuunga whakaurunga, he teitei ake tona uara Q, engari he iti ake te uara Q.Ko te tata atu o te whakangungu rakau, te waahanga whakarewa ranei ki te porowhita, ka tino heke te uara Q.Ko te turanga me te matua autō kia tika te whakarite me te whaitake;Ko te porowhita antenna me te porowhita oscillating me noho tika tetahi ki tetahi, e karo ana i te awe o te hono tahi.

(2) Ko te coil me tirotirohia i mua i te whakaurunga.

I mua i te whakamahi, tirohia mehemea he pakari te hanga o te porowhita, he matara me te wetewete nga hurihanga, he wetewete nga hononga arataki, he ngawari te hurihanga o te matua autō, me te mea he patene reti.Ko enei waahanga he tohu i mua i te whakaurunga.
