Izici eziyinhloko ze-Pneumatic solenoid valves
Ivalvu ye-solenoid, njengesisekeli se-valve epayipini, iyisisetshenziswa esisetshenziselwa ukushintsha-indawo yesigaba esiphambanayo kanye nesiqondiso sokugeleza okumaphakathi, kanye nokulawula ukunyakaza kwendawo edluliswayo. Izici zayo eziyinhloko yilezi:
1. Ukuvuza kwangaphandle kuvinjwe ngokuphelele, ukuvuza kwangaphakathi kulula ukulawula, futhi kuphephile ukukusebenzisa. Ukuvuza kwangaphakathi nangaphandle kwamavalvu kungenye yezinto zokuphepha{2}}ekufakweni kwesayithi. Amanye ama-valve, njengama-valve azilawulayo{4}, ngokuvamile anweba isiqu se-valve futhi alawule ukuzungezisa noma ukunyakaza kwe-valve core ngama-electric, pneumatic, noma ama-hydraulic actuators. Lokhu kudinga ukuxazulula inkinga yokuvuza kwangaphandle kophawu oluguquguqukayo lwesiqu se-valve ngenxa yokusebenza-yesikhathi eside. Ivalvu ye-solenoid isebenza ngokusebenzisa amandla kazibuthe kagesi engxenyeni yensimbi evalwe kumkhono wokuhlukanisa uzibuthe. Alukho uphawu oluguquguqukayo, ngakho ukuvuza kwangaphandle kujwayele ukuvaleka. Isibonelo, ngenxa yokulawulwa kwetorque elinganiselwe yamavalvu kagesi, ajwayele ukuvuza kwangaphakathi futhi angase aphule ngisho nekhanda le-valve stem. I-valve ye-solenoid inesakhiwo esilula, ukubekwa uphawu okuthembekile, futhi kulula ukulawula ukuvuza kwangaphakathi. Ngakho-ke, uma kuqhathaniswa namanye ama-valve, ama-valve e-Pneumatic solenoid aphephile uma kuqhathaniswa futhi afaneleka nakakhulu imidiya edlayo, enobuthi, noma izinga lokushisa eliphezulu neliphansi.
2. I-valve ye-solenoid ngokwayo inesakhiwo esilula kanye nenani eliphansi. Kulula ukuyifaka nokuyinakekela kunezinye izinhlobo zama-actuator, njengama-valve okulawula. Okubaluleke nakakhulu, isistimu yokulawula okuzenzakalelayo eyakhayo ilula. Njengoba i-valve ye-solenoid ilawulwa isignali yokushintsha, kulula kakhulu ukuyixhuma kukhompyutha yokulawula izimboni.
3. Ifaka isenzo esisheshayo, ukusetshenziswa kwamandla okuphansi, nomklamo ongasindi. Isikhathi sokuphendula samavalvu womoya we-solenoid singaba sifushane njengama-millisecond ambalwa, futhi ngisho nama-valve omshayeli we-Pneumatic solenoid asebenzayo angalawuleka phakathi kwamashumi amasekhondi. Ngoba yakha{4}isifunda esizimele, isabela ngokuzwela kakhulu kunamanye ama-automatic control valves. Ikhoyili-eklanywe kahle ye-solenoid valve isebenzisa amandla amancane kakhulu futhi iwumkhiqizo{7}}wonga amandla. Ngohlelo olufanele lwesifunda, kungabuye kufinyelelwe ukuthi indawo ye-valve ingagcinwa ngokuzenzakalelayo ngokubangela isenzo, futhi ayisebenzisi amandla ngaphansi kwezimo ezivamile. Inzuzo enkulu yamavalvu e-Pneumatic solenoid ilele kubukhulu bawo obungaphandle obuncane, obungagcini nje ngokugcina isikhala kodwa futhi bulula futhi bubukeka kahle.
Qaphela.
4. Ukulungiswa kokunemba kokulawula kunomkhawulo, futhi akusebenzi kumidiya ethile. Ama-valve e-solenoid yomoya ngokuvamile anezifunda ezimbili kuphela: avulekile futhi avaliwe. Ivalvu ingaba sezimo ezimbili ezeqisayo kuphela futhi ayikwazi ukulungiswa ngokuqhubekayo (kunemibono eminingi emisha ezama ukubhodloza, kodwa yonke isesigabeni sokuhlola nokusetshenziswa kwesilingo). Ngakho-ke, ukulungiswa okunembayo kungaphansi kwemikhawulo ethile. I-valve ye-solenoid inesidingo esiphezulu kakhulu sokuhlanzeka kwendawo ephakathi. Ayifanele imidiya equkethe izinhlayiya. Uma kukhona ukungcola, kufanele kuhlungwe kuqala. Ngaphezu kwalokho, ngenxa yokungasebenzi kwemidiya ye-viscous, uhla lwe-viscosity olusebenzayo lwemidiya luncane kakhulu.
5. Amamodeli ahlukahlukene kanye nezicelo ezibanzi. Nakuba ama-valve e-Pneumatic solenoid aneziphambeko zemvelo, izinzuzo zawo zisavelele kakhulu. Ngakho-ke, zenzelwe imikhiqizo ehlukahlukene ukuze ihlangabezane nezidingo ezahlukahlukene futhi ibe nezinhlelo zokusebenza ezibanzi kakhulu. Inqubekelaphambili yobuchwepheshe be-valve ye-solenoid nayo igxile endleleni yokunqoba ukushiyeka okungokwemvelo kanye nendlela yokuzuza kangcono izinzuzo ezingokwemvelo. Ngokombono wesimiso sokusebenza, isimo, kanye nezici ze-Pneumatic solenoid valves, ukwakheka kwe-Pneumatic solenoid valves kulula, futhi inqubo yokusebenza ayinzima. Uma nje umklamo unengqondo futhi ukusebenza kunokwethenjelwa ngesikhathi sokusetshenziswa okujwayelekile, ngokuvamile azikho izinkinga. Ngaphezu kwalokho, lapho ukusetshenziswa okuvamile, njengoba kungekho zinhlansi noma amazinga okushisa ayingozi akhiqizwayo, amathuba okuba kubangele ukuqhuma mancane kakhulu. Kodwa-ke, esimweni esingalungile, ngenxa yokuntuleka kokuvikelwa okudingekayo, kungenzeka ukuthi i-valve ye-solenoid ebangela ingozi yokuqhuma izokhula kakhulu.
Ii. Uwehlulela Kanjani Ikhwalithi Yevalvu Kagesi
Izinga levalvu kagesi lincike kakhulu ezintweni ezimbili: ikhoyili nomzimba wevalvu. Ngakho-ke, ukuhlolwa kufanele kugxile kakhulu kulezi zici ezimbili. Ungathola ugesi we-24V bese uwuxhuma kukhoyili. Uma uzwa umsindo, kukhombisa ukuthi kokubili ikhoyili kanye ne-valve core ye-solenoid valve kujwayelekile futhi kungenziwa ngokujwayelekile. Bese uhlola ukuthi kukhona yini ukuvuza. Uma kukhona umthombo wegesi, kungcono ukuxhuma ngokuqondile umthombo wegesi, futhi ungakwazi ukunquma ukuthi kukhona yini ukuvuza. Uma ungekho umthombo wegesi, vala indawo yokukhipha umoya bese uwuphephetha ngomlomo wakho. Ngaphezu kwalokho, ikhoyili ingabuye ihlolwe nge-multimeter.
1. Amandla ku-valve ye-solenoid, khipha ipulaki, futhi usebenzise i-multimeter ukuze ulinganise ukuthi ukhona yini ugesi.
2. Uma i-valve ye-solenoid ivuliwe, sondeza intambo yensimbi encane eduze kwekhoyili ukuze ubone ukuthi akukho yini ukumuncwa.
3. Hlola ngokuphindaphindiwe i-valve ye-solenoid ngokuyivula nokuyivala. Sebenzisa isikrufu sika-Allen esihle kakhulu ukuhlohla "umgodi omncane" embaleni wethusi ku-eksisi yevalvu ye-solenoid ukuze ubone ukuthi ingamuncwa futhi ikhishwe.
Izindlela zokuthola ikhwalithi ye-Pneumatic solenoid valves:
First, connect the medium to be controlled (pressurized liquid, gas < air >, inani lokucindezela elimaphakathi nebanga lokucindezela kokusebenza kwevalvu ye-solenoid) ku-valve ye-solenoid, bese inikezela ngamandla kukhoyili ye-solenoid valve. Uma i-medium elawulwayo ishintsha isimo kusukela ekuqhubekeni ukuya kokuvala noma ukuvala kuya phambili, khona-ke i-valve ye-solenoid isesimweni esihle; kungenjalo, kunenkinga.
Amaphutha ajwayelekile we-Pneumatic solenoid valves
1. I-short circuit noma i-open circuit yekhoyili
Indlela yokutholwa: Okokuqala, linganisela-isimo sayo sokucisha nge-multimeter. Uma inani lokumelana lisondela ku-zero noma i-infinity, libonisa ukuthi ikhoyili imfushane-iyajikeleza noma ivuliwe{3}}izungeza. Uma inani elilinganisiwe lokumelana livamile (cishe ama-ohm ambalwa), akusho ngempela ukuthi ikhoyili isesimweni esihle. Sicela wenze ukuhlolwa kokugcina okulandelayo: Thola i-screwdriver encane bese usibeka eduze kwensimbi efakwe ngekhoyili yevalve ye-solenoid. Bese unikeza amandla ku-valve ye-solenoid. Uma uzizwa uzibuthe, ikhoyili ye-solenoid valve isesimweni esihle; kungenjalo, iphukile. Isixazululo: Faka esikhundleni ikhoyili yevalvu ye-solenoid.
2. Kunenkinga ngepulaki/isokhethi
Iphutha elenzeka: Uma i-valve ye-solenoid iwuhlobo olunepulaki/isokhethi, kungase kube nezinkinga ezifana nepuleti lesiphethu sensimbi lesokhethi noma izintambo kupulaki (isibonelo, intambo yamandla ixhunywe ocingweni lwaphansi), okuvimbela amandla ukuthi angalethwa kukhoyili. Kungcono ukuthuthukisa umkhuba: ngemva kokuba ipulaki ifakwe esokhethi, i-screw on the screw fixing; ngemva kokuba ikhoyili ifakwe ku-valve core rod, screw on the fixing nut.
Uma ipulaki yekhoyili ye-valve ye-solenoid ifakwe ukukhanya kwenkomba yamandla e-LED, khona-ke lapho usebenzisa amandla e-DC ukushayela i-valve ye-solenoid, kufanele ixhunywe ngendlela efanele; ngaphandle kwalokho, ukukhanya kwenkomba ngeke kukhanye. Ngaphezu kwalokho, ungashintshisani amapulagi kagesi nezikhombisi-ezikhipha amandla e-diode amaleveli ahlukene kagesi. Lokhu kungase kubangele ukuthi ukukhanya-kushise/kufishane{4}}kujikelezise amandla kagesi (shintshela kupulaki yeleveli ye-voltage ephansi) noma ukukhishwa kokukhanya okubuthakathaka kakhulu kwesibani{5}}emitting diode (shintshela kupulaki yeleveli ye-voltage ephezulu).
Uma kungekho ukukhanya kwesikhombi samandla, i-polarity yekhoyili yevalve ye-solenoid ayidingi ukuhlukaniswa (ngokungafani nokudluliselwa kwesikhathi se-transistor nge-voltage yekhoyili ye-DC kanye nama-intermediate relay ane-voltage yekhoyili ye-DC kanye nesekhethi yokuvuza kwe-diode/resistor exhunywe ngokuhambisana yikhoyili (iningi lalokhu kudluliselwa okuphakathi nendawo ama-polarity aseJapane angempela), adinga ukuhlukaniswa kwekhoyili yangempela).
Isixazululo: Lungisa amaphutha ezintambo, lungisa noma shintsha amapulaki namasokhethi.
3. Inkinga ye-Valve core
I-Fault Phenomenon 1: Uma ingcindezi ye-medium edlula ku-valve ye-solenoid ivamile, ukucindezela inkinobho ebomvu yesandla ye-solenoid valve ingabangi noma iyiphi impendulo (i-pressure medium ayibonisi noma yikuphi{1}}kuvaliwe ukushintsha), okubonisa ukuthi i-valve core kumele ibe nephutha. Isixazululo: Hlola ukuthi azikho yini izinkinga nge-medium, njengokuthi ingabe kukhona yini ukunqwabelana kwamanzi amaningi emoyeni ocindezelwe (ngezinye izikhathi isihlukanisi samanzi{3}}asidlali indima ebalulekile, ikakhulukazi uma ukwakheka kwepayipi kungalungile, kuzoba khona ukunqwabelana kwamanzi amaningi emoyeni ocindezelwe odlula i-solenoid valve), kanye nokuthi ingabe kukhona ukungcola okuningi okuphakathi nendawo okuwuketshezi okudluliswa khona. Bese ususa amanzi anqwabelene noma ukungcola ku-valve ye-solenoid namapayipi. Uma namanje kungasebenzi, sicela ulungise noma ushintshe i-valve core, noma umane umisele yonke i-valve ye-solenoid.
Iphutha lesi-2: Ngemva kokuhlolwa, kutholakala ukuthi ikhoyili iyona yokuqala futhi impahla kazibuthe ivamile lapho ikhoyili inikwa amandla, kodwa i-valve ye-solenoid namanje ayisasebenzi (okwamanje, umsebenzi wenkinobho ye-manual ye-valve ye-solenoid ingase ibe evamile), okubonisa ukuthi umgogodla we-valve unephutha.
Isixazululo: Sicela ulungise noma ushintshe i-valve core, noma vele ufake i-valve yonke ye-solenoid.
Ngenhla yiziphi izici eziyinhloko zama-valve we-Pneumatic solenoid, kanye nendlela yokwahlulela ikhwalithi yokuqukethwe kwama-valve we-Pneumatic solenoid, Ukuze ufunde ulwazi oluthe xaxa oluhlobene, vakashelahttps://www.joosungauto.com/.
