Pamhando dzose dzemotokari, mabhazi, matirakita uye midziyo yakakosha, mavharuvhu e-solenoid anoshandiswa zvakanyanya kudzora kuyerera kwemvura uye magasi.Verenga nezve izvo solenoid mavharuvhu, marongedzerwa uye kushanda kwawo, uye nzvimbo yaanogara mumidziyo yemotokari mune ino chinyorwa.
Chii chinonzi solenoid valve uye inoshandiswa kupi?
A solenoid valve i electromechanical device ye remote control yekuyerera kwemagasi uye zvinwiwa.
Mune tekinoroji yemotokari, solenoid mavharuvhu anoshandiswa mune akasiyana masisitimu:
- Mune pneumatic system;
- Muiyo hydraulic system;
- Mumafuta system;
- Mune anobatsira masisitimu - ekudzora kure kwekutapurirana zvikamu, dump platform, zvakabatanidzwa uye zvimwe zvishandiso.
Panguva imwecheteyo, solenoid mavharuvhu anogadzirisa maviri makuru mabasa:
- Kudzora kwekuyerera kwesvikiro rekushanda - kupihwa kwemhepo yakamanikidzwa kana mafuta kune akasiyana mayuniti, zvichienderana neanoshanda maitiro ehurongwa;
- Kudzima kupihwa kweiyo yekushanda svikiro mumamiriro ekukurumidzira.
Aya mabasa anogadziriswa ne solenoid mavharuvhu emhando dzakasiyana uye magadzirirwo, ayo anoda kutsanangurwa zvakadzama.
Mhando dze solenoid valves
Chekutanga pane zvese, solenoid mavharuvhu akakamurwa kuita mapoka maviri zvichienderana nerudzi rwekushanda svikiro:
- Air - pneumatic mavharuvhu;
- Fluids - mavharuvhu ehuti system uye hydraulic masisitimu ezvinangwa zvakasiyana.
Zvinoenderana nehuwandu hwekuyerera kwepakati yekushanda uye maficha ekushanda, mavharuvhu akakamurwa kuva marudzi maviri:
- Nzira mbiri - vane mapaipi maviri chete.
- Nzira nhatu - dzine pombi nhatu.
Mavharuvhu maviri ane mapaipi maviri - inlet uye outlet, pakati pawo svikiro rinoshanda rinoyerera munzira imwe chete.Pakati pemapombi pane valve inogona kuzarura kana kuvhara kuyerera kwekushanda kwekushanda, kuve nechokwadi chekupa kwayo kune zvikamu.
Mavharuvhu matatu ane mabhunu matatu anogona kubatanidzwa kune mumwe nemumwe mumisanganiswa yakasiyana-siyana.Semuenzaniso, masisitimu epneumatic anowanzo shandisa mavharuvhu ane imwe inopinza uye maviri epombi yekubuda, uye panzvimbo dzakasiyana dzechinhu chekutonga, mweya wakamanikidzwa kubva mupombi inopinza inogona kupihwa kune imwe yepombi dzekubuda.Kune rumwe rutivi, muEPHX mavharuvhu (akamanikidzirwa idle economizer) pane imwe epomizer uye mapombi maviri ekutora, ayo anopa zvakajairika mhepo uye kuderedzwa kudzvinyirira kune carburetor idling system.
Mavharuvhu maviri-maviri akakamurwa kuita marudzi maviri zvichienderana nenzvimbo yechinhu chekudzora kana electromagnet ichibviswa-simba:
- Kazhinji kuvhurika (NO) - vharafu yakazaruka;
- Kazhinji yakavharwa (NC) - valve yakavharwa.
Zvinoenderana nerudzi rweactuator uye kutonga, mavharuvhu akakamurwa kuva marudzi maviri:
- Mavharuvhu echiito chakananga - kuyerera kwesvikiro rekushanda kunodzorwa chete nesimba rakagadzirwa nemagetsi emagetsi;
- Pilot solenoid valves - kuyerera kwekushanda kwekushanda kunodzorwa muchikamu nekushandisa kudzvinyirira kwepakati pachayo.
Mumotokari nematarakita, mavharuvhu akareruka akananga anoshandiswa zvakanyanya.
Zvakare, mavharuvhu anosiyana mukuita maitiro (supply voltage ye12 kana 24 V, nominal bore uye mamwe) uye magadzirirwo maficha.Kusiyana, zvakakosha kutaura mavharuvhu, anogona kuunganidzwa kuita mabhuroko e2-4 zvidimbu - nekuda kweimwe nzvimbo yepombi uye fasteners (eyelets), anogona kusanganiswa kuita chivakwa chimwe chete nenhamba huru yekupinza uye. pombi dzekubuda.
Iyo yakajairika chimiro uye musimboti wekushanda kwe solenoid mavharuvhu
Ese mavharuvhu e-solenoid, zvisinei nerudzi uye chinangwa, ane dhizaini yakafanana, uye ane akati wandei mazvikamu:
- Electromagnet (solenoid) ine armature yeimwe dhizaini kana imwe;
- Kudzora / kukiya chinhu (kana zvinhu) zvakabatana kune armature ye electromagnet;
- Cavities uye chiteshi chekuyerera kweiyo yekushanda svikiro, yakabatana nefittings kana nozzles pamuviri;-Corps.
Zvakare, vharafu inogona kutakura zvinhu zvakasiyana-siyana zvekubatsira - zvigadziriso zvekugadzirisa kushushikana kwezvitubu kana kurova kwechigadziriso chekudzora, dhiraivha mafirita, mabatiro ekutonga kwemanyore ekuyerera kwepakati yekushanda, switch yekudzora mamwe maturusi zvichienderana nenyika. yevhavha, mafirita, nezvimwe.
Mavharuvhu akakamurwa kuita mapoka matatu zvichienderana nerudzi uye dhizaini yechinhu chekutonga:
- Spool - chinhu chekutonga chinogadzirwa nenzira ye spool, iyo inogona kugovera kuyerera kwekushanda kwekushanda kuburikidza nemigero;
- Membrane - chinhu chekutonga chinogadzirwa nenzira ye elastic membrane;
- Piston - chinhu chekutonga chinogadzirwa muchimiro chepiston padyo nechigaro.
Muchiitiko ichi, vharafu inogona kunge iine imwe, mbiri kana kupfuura yekudzora zvinhu zvakabatana kune imwe armature ye electromagnet.
Nheyo yekushanda yevhavha ye solenoid iri nyore kwazvo.Funga nezvekushanda kweiyo yakapfava-nzira mbiri diaphragm inowanzovharika vharafu inoshandiswa mumafuta ekupa masisitimu.Kana vharuvhu ichibviswa simba, iyo armature inodzvanywa kurwisa diaphragm nekuita kwechitubu, iyo inovhara chiteshi uye inodzivirira fluid kuyerera ichiwedzera kuburikidza nehurongwa.Kana ikozvino inoshandiswa kune electromagnet, magnetic field inomuka mukutenderera kwayo, nekuda kwekuti armature inokweverwa mukati - panguva ino membrane, iyo isingachatsikirwi ne armature, inosimuka pasi pesimba rekumanikidzwa kwekushanda. pakati uye anovhura gwara.Nekuzobviswa kwazvino kubva kune electromagnet, iyo armature iri pasi pechiito chechirimo ichadzokera kunzvimbo yayo yepakutanga, dzvanya membrane uye kuvhara chiteshi.
Mavharuvhu maviri anoshanda nenzira yakafanana, asi anoshandisa spools kana piston-mhando yekudzora zvinhu pachinzvimbo che diaphragm.Semuenzaniso, funga nezvekugadzirwa uye kushanda kweEPHX valve ye carburetor cars.Kana iyo magineti yakadzimwa, iyo armature inosimudzwa pasi pechiito chechirimo, uye chinhu chekuvhara chinovhara chepamusoro, chichibatanidza mativi uye pasi (atmospheric) fittings - mune iyi kesi, kumanikidzwa kwemhepo kunoshandiswa kune EPHH. pneumatic valve, yakavharwa uye iyo carburetor idling system haishande.Kana ikozvino yaiswa kune electromagnet, iyo armature inodzoserwa, kukunda simba rechirimo, inovhara iyo yakaderera yekukodzera, ichivhura iyo yepamusoro, iyo yakabatana nepombi yekupinda injini (apo kuderedzwa kunoonekwa) - mune iyi kesi, a vacuum inoshandiswa kune EPHH pneumatic valve, inovhura uye inoshandura iyo isina basa system.
Solenoid mavharuvhu anovimbika chaizvo uye asingaremekedzi mukushanda, ane akakosha sosi (kusvika mazana ezviuru ezviuru actuations), uye, sekutonga, haadi yakakosha kuchengetedza.Zvisinei, kana pakaitika kusashanda, chero valve inofanira kuchinjwa nokukurumidza sezvinobvira - chete munyaya iyi kushanda kwakakodzera uye kuchengeteka kwemotokari ichave yakasimbiswa.
