Iyini i-Solenoid Valve?
Ii-valve ye-solenoidngokuyisisekelo iyivalvu esesimweni sekhoyili kagesi (noma i-solenoid) kanye ne-plunger esetshenziswa i-actuator eyakhelweyo.Ngakho-ke i-valve iyavuleka futhi ivalwe lapho isignali isuswa ngokubuyisela isignali kagesi endaweni yayo yasekuqaleni (ngokuvamile ngesiphethu).
Iyiphi engcono i-DC noma i-AC Solenoids?
Ngokuvamile, i-DC solenoid ikhethwa kune-AC ngenxa yokuthi ukusebenza kwe-DC akukho ngaphansi kwamagagasi aphezulu aphezulu, okungase kubangele ukushisa ngokweqile kanye nokulimala kwekhoyili ngokuhamba ngebhayisikili njalo noma ukubanjwa kwe-spool ngengozi.
Nokho, lapho kudingeka khona ukusabela okusheshayo noma lapho kusetshenziswa khona izilawuli zikagesi zohlobo oludluliswayo, ama-solenoid e-AC ayakhethwa.
Isikhathi sokuphendula se-AC solenoid valves singu-8-5 μs uma siqhathaniswa ne-30-40 μs evamile yokusebenza kwe-DC solenoid.
Ngokuvamile, i-DC solenoid ikhethwa kune-AC ngenxa yokuthi ukusebenza kwe-DC akukho ngaphansi kwamagagasi aphezulu aphezulu, okungase kubangele ukushisa ngokweqile kanye nokulimala kwekhoyili ngokuhamba ngebhayisikili njalo noma ukubanjwa kwe-spool ngengozi.
Izakhiwo zokusebenza ze-solenoid ezinikezwe amakhoyili e-DC kanye ne-AC DC zihluke kakhulu ngesikhathi sokuphendula futhi zingakwazi ukulawula izingcindezi ezincane kuphela.
Ngesikhathi sokuphendula, amakhoyili e-AC ayashesha futhi angakwazi ukulawula izingcindezi ezinkulu ekuqaleni.
Ngakho-ke, uma kunesidingo, bangakwazi ukugitsheliswa ngamabhayisikili ngamanani asheshayo.Nokho, ukulahlekelwa kukagesi kukhulu futhi kuhambisana nemvamisa ye-AC.(Ukulahlekelwa kwamandla ku-solenoid esebenza nge-AC ene-frequency engu-60 Hz, isibonelo, kukhulu kunalokho ekunikezeni okungu-50-Hz kwekhoyili efanayo).
