Vavu ya Solenoid: Ndi chiyani chomwe chili bwino DC kapena AC Solenoid valve?

Kodi valavu ya solenoid ndi chiyani?

Thevalve solenoidkwenikweni ndi valavu mu mawonekedwe a koyilo yamagetsi (kapena solenoid) ndi plunger yoyendetsedwa ndi cholumikizira chomanga.Choncho valve imatsegulidwa ndi kutsekedwa pamene chizindikirocho chikuchotsedwa mwa kubwezeretsa chizindikiro chamagetsi kumalo ake oyambirira (nthawi zambiri ndi kasupe).

Zomwe zili bwino DC kapena AC Solenoids?

Nthawi zambiri, ma solenoid a DC amakonda kuposa ma AC chifukwa opareshoni ya DC simayenderana ndi mafunde amphamvu kwambiri, omwe angayambitse kutentha kwambiri komanso kuvulaza kwapang'onopang'ono kapena kugwidwa mwangozi.

Komabe, komwe kukufunika kuyankha mwachangu kapena komwe magetsi amtundu wa relay amagwiritsidwa ntchito, ma solenoid a AC amakondedwa.

Nthawi yoyankha kwa ma valve a AC solenoid ndi 8-5 μs poyerekeza ndi 30-40 μs ya DC solenoid operation.

Nthawi zambiri, ma solenoid a DC amakonda kuposa ma AC chifukwa opareshoni ya DC simayenderana ndi mafunde amphamvu kwambiri, omwe angayambitse kutentha kwambiri komanso kuvulaza kwapang'onopang'ono kapena kugwidwa mwangozi.

Zomwe zimagwira ntchito za solenoid zoperekedwa ndi ma coil a DC ndi AC DC ndizosiyana kwambiri panthawi yoyankha ndipo zimatha kuthana ndi zovuta zazing'ono zokha.

Panthawi yoyankha, ma coil a AC amakhala othamanga ndipo amatha kuthana ndi zovuta zazikulu poyamba.

Choncho, ngati n'koyenera, akhoza kupalasa njinga mothamanga kwambiri.Komabe, kutayika kwa magetsi kumakhala kwakukulu ndipo kumagwirizana ndi mafupipafupi a AC.(Kutayika kwa mphamvu mu solenoid yoyendetsedwa ndi AC yokhala ndi mafupipafupi a 60 Hz, mwachitsanzo, ndi yaikulu kuposa yomwe ili mu 50-Hz yopereka koyilo yomweyo).
