Solenoid valve

1.Chii chinonzi solenoid valve
Solenoid vharuvhu chinhu otomatiki chakakosha chinoshandiswa kudzora mvura uye ndeye actuator;Kwete kugumira kune hydraulic uye pneumatic.Iyo solenoid valve inoshandiswa kudzora kutungamira kwe hydraulic kuyerera.Iyo michina michina mufekitari inowanzodzorwa ne hydraulic simbi, saka solenoid valve ichashandiswa.
Nheyo yekushanda yevhavha ye solenoid ndeyokuti kune mhango yakavharwa muvhavha ye solenoid, uye kune kuburikidza nemakomba munzvimbo dzakasiyana.Gomba rega rega rinotungamira kune mapaipi emafuta akasiyana.Pane vharafu pakati pegomba, uye kune maviri magineti emagetsi kumativi ese.Iyo magineti coil padivi rinopa simba muviri wevharuvhu inokwezvwa kune rimwe divi.Nekudzora kufamba kwemuviri wevharuvhu, maburi emafuta akasiyana anovharika kana kudonha.Gomba rekupinda nemafuta rinowanzovhurika, uye mafuta ehydraulic anopinda pombi dzakasiyana dzekudonhedza mafuta, Ipapo kumanikidza kwemafuta kunosundidzira piston yehumburumbira yeoiri, inotyaira piston tsvimbo, uye piston tsvimbo inotyaira mudziyo wemuchina kuti ufambe.Nenzira iyi, iyo mechanical movement inodzorwa nekudzora ikozvino ye electromagnet.
Izvo zviri pamusoro apa ndiyo nheyo huru ye solenoid valve
Kutaura zvazviri, maererano nekushisa uye kudzvinyirira kwepakati inoyerera, somuenzaniso, pombi ine dzvinyiriro uye iyo yega-yega inoyerera haina kumanikidzwa.Nheyo yekushanda ye solenoid valve yakasiyana.
Semuenzaniso, zero-voltage yekutanga inodiwa pasi pesimba regiravhiti, kureva kuti, coil inoyamwa muviri webhureki wese mushure mekubatidzwa.
Iyo solenoid valve ine pressure ipini inopinzwa pamuviri webhureki mushure mekunge coil yasimba, uye bhureki muviri unovharwa nekumanikidzwa kwemvura pachayo.
Musiyano uripo pakati penzira mbiri idzi ndewekuti solenoid vharafu mune yega-yekuyerera mamiriro ine vhoriyamu yakakura nekuti coil inoda kuyamwa muviri wese wegedhi.
Iyo solenoid valve iri pasi pekumanikidzwa inongoda kusveta pini, saka huwandu hwayo hunogona kunge hudiki.
Direct acting solenoid valve:
Nheyo: Kana yasimbiswa, iyo solenoid coil inogadzira simba remagetsi kusimudza chikamu chekuvhara kubva pachigaro chevharuvhu, uye vharuvhu inovhura;Kana simba ragurwa, simba remagetsi rinonyangarika, chitubu chinotsikirira chikamu chekuvhara pachigaro chevharuvhu, uye vharafu inovhara.
Zvimiro: Inogona kushanda zvakajairika pasi pevacuum, kudzvanywa kwakashata uye zero kudzvanywa, asi dhayamita kazhinji haipfuure 25mm.
Yakagoverwa yakananga-inobata solenoid valve:
Nheyo: Iko musanganiswa weakananga-chiito uye mutyairi mhando.Kana pasina mutsauko wekumanikidza pakati pekupinda nekubuda, simba remagetsi rinosimudza zvakananga vheji diki yekutyaira uye chikamu chikuru chekuvhara chevha ichienda kumusoro mushure mekupa simba, uye vharafu inovhura.Kana iyo yekupinza uye yekubuda ichisvika padanho rekutanga rekumanikidza, simba remagetsi rinotyaira vharafu diki, kudzvanywa mukamuri rezasi revharuvhu huru kunokwira, uye kudzvanywa kuri mukamuri yepamusoro kunodonha, kuitira kusunda vharafu huru. kumusoro nekushandisa mutsauko wekumanikidza;Kana simba ragurwa, vheji yekutyaira inoshandisa chitubu simba kana kudzvanywa kwepakati kusundira chikamu chekuvhara uye kudzika pasi kuvhara vharafu.
Zvimiro: Inogonawo kushanda pa zero differential pressure, vacuum uye high pressure, asi simba racho ihombe, saka rinofanirwa kuiswa yakatwasuka.
Pilot inoshanda solenoid valve:
Nheyo: kana yapihwa simba, simba remagetsi rinovhura gomba rekutyaira, uye kudzvanywa kuri mukamuri yepamusoro kunodonha nekukurumidza, kuchiita mutsauko wepamusoro uye wakaderera wakatenderedza chikamu chekuvhara.Mvura inodzvinyirira inosundira chikamu chekuvhara kumusoro, uye valve inovhura;Kana simba ragurwa, simba remuchirimo rinovhara gomba rekutyaira, uye inlet pressure inokurumidza kuumba musiyano wepressure wepasi nepamusoro wakatenderedza mavharuvhu ekuvhara zvikamu kuburikidza neburi rekubypass.Iyo fluid pressure inosundidzira vharafu inovhara zvikamu pasi kuti ivhare valve.
Zvimiro: Muganho wepamusoro weiyo fluid pressure range yakakwira, uye inogona kuiswa zvisina tsarukano (yakagadzirirwa), asi iyo fluid pressure yekusiyanisa mamiriro inofanirwa kusangana.
Iyo mbiri-nzvimbo mbiri-nzira solenoid vharafu inoumbwa nevharuvhu muviri uye solenoid coil.Iyo yakananga-inoshanda chimiro ine yayo bhiriji rectifier redunhu uye overvoltage uye overcurrent kuchengetedza kuchengetedza.
Iyo solenoid coil haina kupihwa simba.Panguva ino, musimboti wesimbi we solenoid vharafu inosendamira kumucheto wepombi kaviri pasi pechiito chechitubu chekudzoka, inovhara pombi mbiri yekupedzisira yekubuda, uye imwe pombi yekupedzisira yekubuda iri munzvimbo yakashama.Iyo firiji inoyerera ichibva kune imwe pombi inopera yekubuda pombi ye solenoid vharafu kuenda kune evaporator yefiriji, uye firiji evaporator inoyerera ichidzokera kune compressor kuti ione kutenderera kwefiriji.
Iyo solenoid coil inopihwa simba.Panguva ino, musimboti wesimbi we solenoid valve inokunda simba rechitubu chekudzoka uye ichienda kune imwe pombi inopera pasi pekuita kwesimba remagetsi, inovhara pombi imwe chete yekubuda kunze, uye pombi mbiri yekupedzisira yekubuda iri pachena. state.Iyo firiji inoyerera ichibva kune kaviri pombi yekupedzisira yekubuda pombi ye solenoid vharafu kuenda kune firiji evaporator uye inodzokera kune compressor kuti ione kutenderera kwefiriji.
Iyo mbiri-nzvimbo nhatu-nzira solenoid vharafu inoumbwa nevharuvhu muviri uye solenoid coil.Iyo yakananga-inoshanda chimiro ine bhiriji rectifier redunhu uye overvoltage uye overcurrent kuchengetedza kuchengetedza А?Br> Kushanda nyika 1 muhurongwa: iyo solenoid valve coil haina simba.Panguva ino, musimboti wesimbi we solenoid vharafu inosendamira kumucheto wepombi kaviri pasi pechiito chechitubu chekudzoka, inovhara pombi mbiri yekupedzisira yekubuda, uye imwe pombi yekupedzisira yekubuda iri munzvimbo yakashama.Iyo firiji inoyerera ichibva kune imwe pombi inopera yekubuda pombi ye solenoid vharafu kuenda kune evaporator yefiriji, uye firiji evaporator inoyerera ichidzokera kune compressor kuti ione kutenderera kwefiriji.(Ona Mufananidzo 1)
Kushanda nyika 2 muhurongwa: solenoid valve coil inosimbiswa.Panguva ino, musimboti wesimbi we solenoid valve inokunda simba rechitubu chekudzoka uye ichienda kune imwe pombi inopera pasi pekuita kwesimba remagetsi, inovhara pombi imwe chete yekubuda kunze, uye pombi mbiri yekupedzisira yekubuda iri pachena. state.Iyo firiji inoyerera ichibva kune kaviri pombi yekupedzisira yekubuda pombi ye solenoid vharafu kuenda kune firiji evaporator uye inodzokera kune compressor kuti ione kutenderera kwefiriji.
