Valve ya Solenoid

1.Kodi valavu ya solenoid ndi chiyani
Valavu ya Solenoid ndi chinthu chodziwikiratu chomwe chimagwiritsidwa ntchito kuwongolera madzimadzi ndipo ndi cha actuator;Osati kokha ku hydraulic ndi pneumatic.Valavu ya solenoid imagwiritsidwa ntchito kuwongolera komwe kumayendera ma hydraulic.Zipangizo zamakina mu fakitale nthawi zambiri zimayendetsedwa ndi chitsulo cha hydraulic, kotero valavu ya solenoid idzagwiritsidwa ntchito.
Mfundo yogwiritsira ntchito valavu ya solenoid ndi yakuti pali malo otsekedwa mu valavu ya solenoid, ndipo pali mabowo m'malo osiyanasiyana.Bowo lililonse limatsogolera ku mapaipi amafuta osiyanasiyana.Pali valavu pakati pa mtsempha, ndipo pali ma electromagnets awiri mbali zonse.Koyilo ya maginito yomwe mbali yomwe imapatsa mphamvu valavu idzakopeka ndi mbali iti.Powongolera kayendedwe ka valavu, mabowo osiyanasiyana amathira mafuta amatsekedwa kapena kutayikira.Bowo lolowera mafuta nthawi zambiri limatseguka, ndipo mafuta a hydraulic amalowa m'mapaipi osiyanasiyana akukhetsa mafuta, Kenako kuthamanga kwamafuta kumakankhira pisitoni ya silinda yamafuta, yomwe imayendetsa ndodo ya pisitoni, ndipo ndodo ya pistoni imayendetsa makinawo kuti asunthe.Mwa njira iyi, kayendetsedwe ka makina kumayendetsedwa ndi kulamulira panopa maginito amagetsi.
Pamwambapa ndi mfundo yaikulu ya valavu solenoid
Ndipotu, malinga ndi kutentha ndi kupanikizika kwa sing'anga yothamanga, mwachitsanzo, payipi imakhala ndi kupanikizika ndipo dziko lodziyendetsa palokha liribe mphamvu.Mfundo yogwira ntchito ya valve solenoid ndi yosiyana.
Mwachitsanzo, kuyambitsa zero-voltage kumafunika pansi pa mphamvu yokoka, ndiko kuti, koyilo imayamwa thupi lonse la brake pambuyo poyatsidwa.
Valve ya solenoid yokhala ndi kukakamiza ndi pini yomwe imayikidwa pathupi la brake pambuyo poti koyiloyo yapatsidwa mphamvu, ndipo thupi la brake limakwezedwa ndi kuthamanga kwamadzimadzi komweko.
Kusiyanitsa pakati pa njira ziwirizi ndikuti valavu ya solenoid yomwe imadziyendetsa yokha imakhala ndi voliyumu yayikulu chifukwa koyiloyo imayenera kuyamwa chipata chonse.
Valavu ya solenoid pansi pa kupanikizika imangofunika kuyamwa pini, kotero kuti voliyumu yake ikhoza kukhala yaying'ono.
Direct acting solenoid valve:
Mfundo Yofunika: Mukapatsidwa mphamvu, solenoid coil imapanga mphamvu yamagetsi kuti ikweze mbali yotseka kuchokera pampando wa valve, ndipo valavu imatsegula;Mphamvu ikadulidwa, mphamvu yamagetsi imasowa, kasupe amakankhira mbali yotseka pampando wa valve, ndipo valavu imatseka.
Mawonekedwe: Itha kugwira ntchito nthawi zonse pansi pa vacuum, kupanikizika koyipa ndi kukakamiza kwa ziro, koma m'mimba mwake nthawi zambiri sadutsa 25mm.
Valavu ya solenoid yogawidwa molunjika:
Mfundo yofunikira: Ndi kuphatikiza kwa machitidwe achindunji ndi mtundu wa woyendetsa.Ngati palibe kusiyana kwapakati pakati pa cholowera ndi chotuluka, mphamvu yamagetsi imakweza mwachindunji valavu yaying'ono yoyendetsa ndi gawo lalikulu lotsekera m'mwamba pambuyo kupatsa mphamvu, ndipo valavu imatsegulidwa.Pamene cholowera ndi chotuluka chifika pakusiyana koyambira, mphamvu yamagetsi imayendetsa valavu yaying'ono, kupanikizika m'chipinda cham'munsi cha valavu yayikulu kumakwera, ndipo kupanikizika m'chipinda chapamwamba kumatsika, kuti akankhire valavu yayikulu. kukwera pamwamba pogwiritsa ntchito kusiyana kwa kuthamanga;Mphamvu ikadulidwa, valavu yoyendetsa ndege imagwiritsa ntchito mphamvu ya masika kapena kukakamiza kwapakatikati kukankhira gawo lotseka ndikusunthira pansi kutseka valavu.
Mawonekedwe: Itha kugwiranso ntchito paziro losiyanitsidwa ndi zero, vacuum ndi kuthamanga kwambiri, koma mphamvu ndi yayikulu, chifukwa chake iyenera kukhazikitsidwa mozungulira.
Valavu ya solenoid yoyendetsa ndege:
Mfundo : ikapatsidwa mphamvu, mphamvu yamagetsi imatsegula dzenje loyendetsa ndege, ndipo kuthamanga kwa chipinda chapamwamba kumatsika mofulumira, kupanga kusiyana kwakukulu ndi kutsika kwapakati kuzungulira gawo lotseka.Kuthamanga kwamadzimadzi kumakankhira mbali yotseka mmwamba, ndipo valavu imatsegula;Mphamvu ikadulidwa, mphamvu ya masika imatseka dzenje loyendetsa, ndipo kukakamiza kolowera kumapangitsa kusiyana kwapang'onopang'ono kwapansi ndi kumtunda kuzungulira gawo lotseka la valve kudzera pabowo lodutsa.Kuthamanga kwamadzimadzi kumakankhira mbali zotsekera za valve pansi kuti zitseke valavu.
Mawonekedwe: Malire apamwamba a kuchuluka kwa kuthamanga kwamadzimadzi ndi okwera, ndipo amatha kukhazikitsidwa mosasamala (zosinthidwa mwamakonda), koma kusiyana kwa kuthamanga kwamadzimadzi kuyenera kukwaniritsidwa.
Valavu yokhala ndi mbali ziwiri ya solenoid imapangidwa ndi thupi la valavu ndi solenoid coil.Ndilo dongosolo lochita zinthu mwachindunji lomwe lili ndi dera lake lokonzanso mlatho komanso kuchulukitsa kwachitetezo komanso chitetezo chambiri.
Chophimba cha solenoid sichimapatsidwa mphamvu.Panthawiyi, chitsulo chachitsulo cha solenoid valve chimatsamira kumapeto kwa chitoliro chachiwiri pansi pa masika obwerera, kutseka chitoliro chapawiri, ndipo chitoliro chimodzi chokha chimakhala chotseguka.Firiji imayenda kuchokera ku chitoliro chimodzi chomaliza cha chitoliro cha solenoid valavu kupita ku evaporator ya firiji, ndipo evaporator ya firiji imabwerera ku kompresa kuti izindikire kuzungulira kwa firiji.
Chophimba cha solenoid chimakhala ndi mphamvu.Panthawiyi, chitsulo chachitsulo cha solenoid valavu chimagonjetsa mphamvu ya kasupe wobwerera ndikusunthira kumapeto kwa chitoliro chimodzi pansi pa mphamvu yamagetsi, kutseka chitoliro chimodzi, ndipo chitoliro chomaliza cha chitoliro chimakhala poyera. boma.Firiji imayenda kuchokera papaipi yapawiri yomaliza ya chitoliro cha solenoid valavu kupita ku evaporator ya firiji ndikubwerera ku compressor kuti izindikire kuzungulira kwa firiji.
Valavu yokhala ndi mbali ziwiri ya solenoid imakhala ndi thupi la valve ndi solenoid coil.Ndi mawonekedwe achindunji okhala ndi bridge rectifier rectifier ndi overvoltage ndi overcurrent chitetezo chitetezo А?Br> Kugwira ntchito 1 m'dongosolo: valavu ya solenoid siipatsidwa mphamvu.Panthawiyi, chitsulo chachitsulo cha solenoid valve chimatsamira kumapeto kwa chitoliro chachiwiri pansi pa masika obwerera, kutseka chitoliro chapawiri, ndipo chitoliro chimodzi chokha chimakhala chotseguka.Firiji imayenda kuchokera ku chitoliro chimodzi chomaliza cha chitoliro cha solenoid valavu kupita ku evaporator ya firiji, ndipo evaporator ya firiji imabwerera ku kompresa kuti izindikire kuzungulira kwa firiji.(Onani chithunzi 1)
Kugwira ntchito 2 mu dongosolo: valavu solenoid coil ndi mphamvu.Panthawiyi, chitsulo chachitsulo cha solenoid valavu chimagonjetsa mphamvu ya kasupe wobwerera ndikusunthira kumapeto kwa chitoliro chimodzi pansi pa mphamvu yamagetsi, kutseka chitoliro chimodzi, ndipo chitoliro chomaliza cha chitoliro chimakhala poyera. boma.Firiji imayenda kuchokera papaipi yapawiri yomaliza ya chitoliro cha solenoid valavu kupita ku evaporator ya firiji ndikubwerera ku compressor kuti izindikire kuzungulira kwa firiji.
