Don John Deere 310J 843K 310K na'ura mai aiki da karfin ruwa solenoid bawul KV25678 SV98-T39S 12V

An gabatar da ƙa'idar aiki na daidaitaccen bawul ɗin sarrafawa na lantarki

Ya dogara ne akan ka'idar solenoid on-off valve: lokacin da wutar lantarki ta kashe, bazara yana danna ainihin kai tsaye a kan wurin zama, yana haifar da bawul ɗin rufewa. Lokacin da nada ya sami kuzari, ƙarfin lantarki da aka haifar yana shawo kan ƙarfin bazara kuma ya ɗaga ainihin, don haka buɗe bawul. Madaidaicin bawul ɗin solenoid yana yin wasu canje-canje ga tsarin bawul ɗin solenoid: yana haifar da ma'auni tsakanin ƙarfin bazara da ƙarfin lantarki a ƙarƙashin kowane halin yanzu na coil. Girman coil halin yanzu ko girman ƙarfin lantarki na lantarki zai shafi buguwar plunger da buɗewar bawul, kuma buɗewar bawul (gudanarwa) da na'urar yanzu (siginar sarrafawa) kyakkyawar alaƙa ce ta madaidaiciya. Bawul ɗin solenoid mai aiki kai tsaye yana gudana ƙarƙashin wurin zama. Matsakaicin yana gudana daga ƙarƙashin wurin zama, kuma jagorancin ƙarfin daidai yake da ƙarfin lantarki, kuma akasin ƙarfin bazara. Sabili da haka, ya zama dole don saita ƙima mai girma da ƙarami daidai da kewayon aiki (coil current) a cikin yanayin aiki. Madaidaicin bawul ɗin solenoid na ruwan Drey yana rufe (NC, nau'in rufaffiyar al'ada) lokacin da wutar ke kashe.
