Kubwereranso ndi chiyanivalve solenoid?
Valavu yosinthira ya solenoid, yomwe imadziwikanso kuti valavu ya solenoid, imagwiritsa ntchito mphamvu yoyamwa ya maginito amagetsi kuwongolera kayendedwe ka valavu kuti ibwerere kumbuyo. Valavu yamagetsi imakhala ndi magawo awiri: valavu ya spool ndi electromagnet.
Malinga ndi magwero osiyanasiyana amagetsi, ma elekitikitimu amatha kugawidwa m'mitundu iwiri: ma elekitikitimu a AC ndi ma electromagnets a DC.
Kutengera ngati mbali ya maginito amagetsi imamizidwa mumafuta, maginito amagetsi amatha kugawidwa mumtundu wouma-mtundu ndi wonyowa-.
Ubwino, kuipa, komanso kugwiritsa ntchito ma valve owongolera a solenoid
Imagwira ntchito mwachangu, yosavuta kugwiritsa ntchito, e komanso yosavuta kuwongolera zokha. Chifukwa cha kuchepa kwa kukula kwa ma elekitiromaginito, mphamvu yamagetsi yamagetsi imakhala yochepa ndipo imatha kugwiritsidwa ntchito pamakina omwe ali ndi mafunde ang'onoang'ono.
Mfundo yogwirira ntchito ya valavu ya solenoid yobwerera
Pali pakati pa valavu yosuntha. Pa mbali iliyonse ya valve, pali electromagnet. Mbali imodzi ikayatsidwa, nsonga ya valve imasunthira mbali imeneyo pansi pa machitidwe a electromagnet, ndipo mbali inayo imagwirizanitsidwa. Pamene mphamvu yazimitsidwa, phata la valve limabwerera pakati pofika masika. Kaya pali ndimeyi pakati zimadalira ntchito zake zandale. O-mtundu sunalumikizidwe, H-mtundu walumikizidwa, ndi zina zotero.
Valavu yobwerera ya solenoid imatenga ma elekitiroma a AC kapena DC onyowa. Valavu ya solenoid imayang'anira malo osiyanasiyana ogwirira ntchito apakati pa valve kudzera pa electromagnet. Magneti yamagetsi ikatha-mphamvu, phata la vavu limasungidwa pakati kapena malo othawirako ndi kuthamanga kwa masika (kupatula ma valve othamanga). Pamene electromagnet ipatsidwa mphamvu, chigawo cha valve chimakankhidwira kumalo ogwirira ntchito. Mphamvuyo ikatha, imabwerera ku chikhalidwe choyambirira. Panthawiyi, kukankhira batani loyang'ana zolakwika ndi dzanja kumatha kusuntha pakati pa valve.
Pamene ma elekitiromu wonyowa amalumikizidwa mkati ndi chipinda chamafuta obwerera, zida zimasuntha mumafuta, zomwe zimatha kuchepetsa kutha, kubisa, ndikuwongolera magwiridwe antchito a kutentha, potero kumakulitsa moyo wautumiki. Ma elekitiromu a AC ali ndi mawonekedwe anthawi yayifupi yochitapo kanthu, dera losavuta lowongolera magetsi komanso osafunikira chitetezo chapadera. Ma electromagnets a Dc ali ndi mawonekedwe osinthira mofewa, ma frequency okwera kwambiri, samakhudzidwa ndi kuchuluka kapena kutsika kwamagetsi, ndipo amagwira ntchito modalirika.
Awiri-magawo atatu-wanjira ya electromagnetic directional control valve
Mphamvu ikadulidwa: P → A ndi B sizilumikizidwa.
Ikayatsidwa: P→ B, A sinalumikizidwe.
2) Mavavu atatu-wamalo anayi{2}}wanjira ya electromagnetic directional control
Ma elekitikitimu onse akakhala-athetsedwa mphamvu: P, A, B ndi T onse amachotsedwa.
Pamene electromagnet kumapeto kumanzere ndi mphamvu: P→ A, B→ T.
Pamene maginito amagetsi kumapeto kumanja apatsidwa mphamvu: P→ B, A→ T.
Kapangidwe ka valavu ya solenoid yobwerera
