Kuzo zonke izinhlobo zezimoto, amabhasi, ogandaganda nemishini ekhethekile, ama-valve e-solenoid asetshenziswa kabanzi ukulawula ukugeleza koketshezi namagesi.Funda mayelana nokuthi ayini ama-solenoid valves, ahlelwa kanjani futhi asebenza kanjani, nokuthi ahlala kuphi emishinini yezimoto kulesi sihloko.
Iyini i-valve ye-solenoid futhi isetshenziswa kuphi?
I-valve ye-solenoid iyisisetshenziswa se-electromechanical sokulawula kude ukuhamba kwamagesi noketshezi.
Kubuchwepheshe bezimoto, ama-valve e-solenoid asetshenziswa ezinhlelweni ezahlukahlukene:
- Kuhlelo lwe-pneumatic;
- Kuhlelo lwamanzi;
- In the system fuel;
- Kuzinhlelo ezisizayo - zokulawula okukude kwamayunithi okudlulisela, ipulatifomu yokulahla, okunamathiselwe namanye amadivaysi.
Ngesikhathi esifanayo, ama-valve e-solenoid axazulula imisebenzi emibili eyinhloko:
- Ukulawulwa kokugeleza kwendawo yokusebenza - ukuhlinzekwa komoya ocindezelwe noma uwoyela kumayunithi ahlukahlukene, kuye ngokuthi imodi yokusebenza yesistimu;
- Ukukhubaza ukuhlinzekwa kwendawo yokusebenza ezimeni eziphuthumayo.
Le misebenzi ixazululwa ngama-valve e-solenoid ezinhlobonhlobo nemiklamo, okudingeka ichazwe ngokuningiliziwe.
Izinhlobo zama-valve e-solenoid
Okokuqala, ama-valve e-solenoid ahlukaniswe ngamaqembu amabili ngokusho kohlobo lwe-medium yokusebenza:
- Air - amavalvu womoya;
- Uketshezi - amavalvu esistimu kaphethiloli kanye namasistimu asebenza ngamanzi ngezinhloso ezehlukene.
Ngokuya ngenani lokugeleza kwendawo yokusebenza kanye nezici zokusebenza, ama-valve ahlukaniswe izinhlobo ezimbili:
- Izindlela ezimbili - zinamapayipi amabili kuphela.
- Indlela emithathu - ibe namapayipi amathathu.
Ama-valve anezindlela ezimbili anamapayipi amabili - i-inlet ne-outlet, phakathi kwawo indlela yokusebenza igeleza ohlangothini olulodwa kuphela.Phakathi kwamapayipi kukhona i-valve engavula noma ivale ukugeleza kwendawo yokusebenza, iqinisekise ukunikezwa kwayo kumayunithi.
Ama-valve anezindlela ezintathu anezimbobo ezintathu ezingaxhunywa komunye nomunye ngezinhlanganisela ezihlukahlukene.Isibonelo, amasistimu we-pneumatic ngokuvamile asebenzisa ama-valve anepayipi elilodwa lokungena kanye namapayipi amabili aphumayo, futhi ezindaweni ezihlukene zesici sokulawula, umoya ocindezelwe ophuma epayipini lokungena unganikezwa kwelinye lamapayipi okukhipha.Ngakolunye uhlangothi, kuma-valve e-EPHX (i-economizer engasebenzi ephoqelelwe) kukhona i-exhaust eyodwa kanye namapayipi amabili okuphuza, ahlinzeka ngokucindezela okujwayelekile komkhathi nokunciphisa ohlelweni lwe-carburetor idling.
Ama-valve anezindlela ezimbili ahlukaniswe abe izinhlobo ezimbili ngokuya ngesimo sesici sokulawula lapho i-electromagnetic ikhishwa amandla:
- Imvamisa ivuliwe (CHA) - i-valve ivuliwe;
- Ngokuvamile kuvalwe (NC) - i-valve ivaliwe.
Ngokusho kohlobo lwe-actuator nokulawula, ama-valve ahlukaniswe abe izinhlobo ezimbili:
- Ama-valve esenzo esiqondile - ukugeleza kwendawo yokusebenza kulawulwa kuphela amandla athuthukiswe yi-electromagnetic;
- I-pilot solenoid valves - ukugeleza kwendawo yokusebenza kulawulwa ngokwengxenye ngokusebenzisa ukucindezela kwendawo ngokwayo.
Ezimotweni nakogandaganda, ama-valve asebenza ngokuqondile alula asetshenziswa kaningi.
Futhi, ama-valve ahluke ezicini zokusebenza (i-voltage yokuhlinzeka ye-12 noma i-24 V, i-bore ebizwa ngokuthi i-bore nabanye) kanye nezici zokuklama.Ngokwehlukana, kufanelekile ukusho ama-valve, angahlanganiswa abe ngamabhulokhi wezingcezu ezingu-2-4 - ngenxa yesikhundla esithile samapayipi kanye nezinsimbi (ama-eyelets), angahlanganiswa abe isakhiwo esisodwa ngenani elikhulu lokungena kanye amapayipi okukhipha.
Isakhiwo esijwayelekile kanye nesimiso sokusebenza kwama-valve e-solenoid
Wonke ama-valve e-solenoid, kungakhathaliseki ukuthi hlobo luni nenjongo, anomklamo ofanayo, futhi anezakhi ezimbalwa eziyinhloko:
- I-Electromagnet (solenoid) ene-armature yomklamo owodwa noma enye;
- Isici sokulawula / sokukhiya (noma izakhi) ezixhunywe ku-armature ye-electromagnetic;
- Imigodi kanye neziteshi zokugeleza kwendawo yokusebenza, exhunywe kuzinto zokufakwa noma imibhobho emzimbeni;-Amasosha.
Futhi, i-valve ingakwazi ukuthwala izakhi ezisizayo ezihlukahlukene - amadivaysi okulungisa ukungezwani kweziphethu noma ukushaywa kwedivayisi yokulawula, ukufakwa kwe-drain, izibambo zokulawula ukugeleza kwendawo yokusebenza, ukushintshwa kokulawula amanye amadivaysi kuye ngokuthi isimo sinjani. we-valve, izihlungi, njll.
Ama-valve ahlukaniswe ngamaqembu amathathu ngokusho kohlobo nomklamo wesici sokulawula:
- I-Spool - isici sokulawula senziwa ngendlela ye-spool, engasabalalisa ukugeleza kwendawo yokusebenza ngokusebenzisa iziteshi;
- I-Membrane - isici sokulawula senziwa ngendlela ye-elastic membrane;
- I-Piston - isici sokulawula senziwa ngendlela ye-piston eduze kwesihlalo.
Kulokhu, i-valve ingaba neyodwa, izakhi zokulawula ezimbili noma ngaphezulu ezixhunywe ku-armature eyodwa ye-electromagnet.
Isimiso sokusebenza se-valve ye-solenoid silula kakhulu.Cabangela ukusebenza kwe-diaphragm ye-diaphragm elula yezindlela ezimbili evamise ukuvaleka esetshenziswa ezinhlelweni zokuphakela uphethiloli.Lapho i-valve ikhishwa amandla, i-armature icindezelwa ngokumelene ne-diaphragm ngesenzo sesiphethu, esivimba isiteshi futhi sivimbele uketshezi ukuthi luqhubeke lugeleza ohlelweni.Lapho i-current isetshenziswa ku-electromagnetic field, kuphakama inkambu kazibuthe ekujikeni kwayo, ngenxa yokuthi i-armature idonselwa ngaphakathi - kulo mzuzu ulwelwesi olungasacindezelwe yi-armature, lukhuphuka ngaphansi kwethonya lokucindezela kokusebenza. medium bese evula isiteshi.Ngokususwa okulandelayo kwamanje ku-electromagnetic, i-armature ngaphansi kwesenzo sentwasahlobo izobuyela endaweni yayo yasekuqaleni, cindezela ulwelwesi futhi uvimbele isiteshi.
Ama-valve anezindlela ezimbili asebenza ngendlela efanayo, kodwa asebenzisa ama-spools noma izakhi zokulawula uhlobo lwe-piston esikhundleni se-diaphragm.Isibonelo, cabangela ukuklama nokusebenza kwe-valve ye-EPHX yezimoto ze-carburetor.Lapho i-electromagnetic de-energized, i-armature iphakanyiselwa phezulu ngaphansi kwesenzo sentwasahlobo, futhi isici sokukhiya sivala ukufakwa okuphezulu, ukuxhuma izifakelo eziseceleni nezingaphansi (zomkhathi) - kulokhu, ukucindezela komkhathi kusetshenziswa ku-EPHH. i-valve ye-pneumatic, ivaliwe futhi i-carburetor idling system ayisebenzi.Lapho i-current isetshenziswa ku-electromagnetic, i-armature iyahoxiswa, inqoba amandla entwasahlobo, ivala ukufakwa okuphansi, ngenkathi ivula engaphezulu, exhunywe kwipayipi yokungenisa injini (lapho ukucindezela okuncishisiwe kubonakala khona) - kulokhu, a i-vacuum isetshenziswa ku-valve yomoya ye-EPHH, ivula futhi ivule uhlelo lokungenzi lutho.
Ama-valve e-Solenoid anokwethenjelwa kakhulu futhi awathobeki ekusebenzeni, anensiza ebalulekile (kufika kumakhulu ambalwa ezinkulungwane zama-actuations), futhi, njengomthetho, akudingi ukunakekelwa okukhethekile.Kodwa-ke, uma kwenzeka ukungasebenzi kahle, noma iyiphi i-valve kufanele ishintshwe ngokushesha ngangokunokwenzeka - kuphela kulokhu ukusebenza okudingekayo nokuphepha kwemoto kuzoqinisekiswa.
