Mumotokari dzekutonhodza masisitimu ane electric fan drive, feni inobatidzwa nekudzima kana tembiricha inotonhorera yachinja.Basa guru muhurongwa rinoitwa ne fan fan on sensor - unogona kudzidza zvose pamusoro pechikamu ichi kubva munyaya ino.
Chii chinonzi fan switch-on sensor?
A fan switch-on sensor chinhu chemagetsi kana che electromechanical chine boka rekusangana (mapoka) rinovhara kana kuvhura dunhu remagetsi zvichienderana nekupisa.Iyo sensor inosanganisirwa mumagetsi ekupa dunhu kana kutonga kwedhiraivha yemagetsi feni yeinjini yekutonhodza system, chinhu chinonzwisa tsitsi chinopa chiratidzo chekubatidza kana kudzima fan zvichienderana nekupisa kweinotonhorera (inotonhorera) .
Aya masensa anongo shandiswa mumotokari dzine magetsi anofambiswa neradiyeta yekutonhodza mafeni.Injini inofambiswa necrankshaft mafeni inobatidzwa nekudzimwa nenzira yeviscous clutch kana nedzimwe nzira dzisingatariswe pano.
Mhando dze fan switch-on sensors
Ese ma sensors e fan akakamurwa kuita mapoka maviri zvinoenderana nemusimboti wekushanda:
•Electromechanical;
•Emagetsi.
Zvakare, electromechanical sensors yakakamurwa kuva marudzi maviri:
• Nechinhu chekunzwa chinobva pamvura inoshanda ine coefficient yakakwirira yekuwedzera (wax);
• Nechinhu chinonzwa chinobva pane bimetallic plate.
Nekuda kwemaitiro ekugadzira, electromechanical sensors inogona kubatanidzwa yakananga kune fan simba rekupa wedunhu (kunyangwe kazhinji iyo sensor inosanganisirwa mufan relay wedunhu), uye masensa emagetsi anogona kungobatanidzwa kune fan drive control circuit.
Zvakare, electromechanical sensors yakakamurwa kuita marudzi maviri zvichienderana nehuwandu hwemapoka ekusangana:
• Single-speed - ivai neboka rimwe chete rekuonana, iro rinovhara mune imwe nzvimbo yekushisa;
• Two-speed - iva nemapoka maviri ekuonana anovhara patembiricha dzakasiyana, izvo zvinokutendera kuti uchinje kumhanya kwefani zvichienderana nekudziya kwekutonhora.
Muchiitiko ichi, mapoka ekuonana anogona kunge ari mune imwe yematunhu maviri: anowanzo kuvhurika uye anowanzo kuvharwa.Muchiitiko chekutanga, feni inotendeuka kana vabatanidzi vakavharwa, mune yechipiri - pavanovhura (yekuwedzera kudzora maseketi anogona kushandiswa pano).
Pakupedzisira, masensa anosiyana mukupisa / kudzima tembiricha yevateveri.Mumidziyo yemumba, mapindiro e82-87, 87-92 uye 94-99 ° C anopiwa, mumidziyo yekune dzimwe nyika nguva dzetembiricha dzinogara dzinenge mukati memiganhu yakafanana, inosiyana nedhigirii rimwe kusvika maviri.
Dhizaini uye musimboti wekushanda kweiyo electromechanical sensor ine wakisi
Iyi ndiyo inonyanya kuzivikanwa mhando ye fan sensors.Hwaro hwe sensor igaba rakazadzwa nepetroleum wax (ceresite, inonyanya kuve neparafini) ine musanganiswa wehupfu yemhangura.Chigaba chine wakisi chakavharwa ne membrane inochinjika panowanikwa pusher, yakabatana nemashini ekufambisa kwepanofambika.Iyo yekubatanidza drive inogona kuve yakananga (ichishandisa imwechete pusher) kana isina kunanga, uchishandisa lever uye chitubu (munyaya iyi, kuvharika kwakavimbika uye kuvhurwa kwedunhu kunowanikwa).Zvikamu zvese zvakavharirwa mune gobvu-yakavakirwa simbi kesi (izvi zvinopa kuwedzera yunifomu kupisa kwemvura inoshanda) neshinda uye chinongedzo chemagetsi.
Nheyo yekushanda kwesensor yakadaro inobva pakuita kwekuchinja kwehuwandu hwemvura inoshanda kana kutonhora kuchichinja (inoshandiswawo mumotokari thermostats).Wax, iyo inobata basa remvura inoshanda mu sensor, ine yakakura coefficient yekuwedzera kwekupisa, kana ichipisa, inowedzera uye inobviswa kubva mumudziyo.Wakisi iri kukura inomira pa membrane uye inoita kuti isimuke - iyo, inofambisa iyo inosundidzira uye inovhara ma contact - fan inobatidza.Kana tembiricha yadonha, membrane inodzikira uye vanobatika vanovhura - fan inodzima.
Maviri-speed sensors anoshandisa, zvichiteerana, maviri membranes uye maviri anofambiswa anobatika, ayo anokonzereswa panguva dzakasiyana tembiricha.
Iyo sensor yakaiswa pane inotonhorera radiator (kuburikidza nechisimbiso gasket), chikamu chayo chekushanda chiri kutarisana zvakananga neinotonhorera, kubva kune iyo inoshanda mvura inopisa.Kazhinji, mota inoshandisa imwe fan fan, asi nhasi unogona kuwana mhinduro nemasensa maviri-speed sensors akaiswa kune tembiricha dzakasiyana.
Dhizaini uye musimboti wekushanda kwe sensor ine bimetallic plate
Kune akawanda marudzi ema sensors emhando iyi, asi kazhinji, dhizaini yavo iri nyore.Nheyo ye sensor iplate ye bimetallic yeimwe chimiro kana imwe, pane iyo inofambiswa kusangana iripo.Panogonawo kunge paine zvikamu zvekubatsira mune sensor kune yakavimbika yekuvhara yekuvhara.Iyo ndiro inoiswa mune yakavharwa simbi kesi, iyo inopa shinda uye yemagetsi connector yekubatanidza kune fan control system.
Nheyo yekushanda kwe sensor inobva pane chiitiko che deformation ye bimetallic plate kana kutonhora kuchichinja.Bimetallic plate mahwendefa maviri esimbi akabatanidzwa kune mumwe nemumwe ane akasiyana coefficients ekuwedzera kwekupisa.Sezvo tembiricha ichikwira, simbi dzinowedzera nenzira dzakasiyana, semhedzisiro, iyo bimetallic ndiro inokotama uye inofambisa iyo inofambiswa kusangana - dunhu rinovhara (kana kuvhura neanowanzo kuvharwa mameta), fan inotanga kutenderera.
Iyo sensor yekubatanidza yakafanana neyakatsanangurwa pamusoro.Masensa emhando iyi ndiwo mashoma akajairika nekuda kwemutengo wavo wepamusoro uye kuoma.
Dhizaini uye musimboti wekushanda kweiyo sensor yemagetsi
Zvimiro, sensor iyi zvakare yakapusa: yakavakirwa pane thermistor yakaiswa muhombe simbi kesi ine tambo yekupinza muradiator uye yemagetsi yekubatanidza.
Nheyo yekushanda kwe sensor inobva pamigumisiro yekushandura kupikisa kwemagetsi kwe thermistor kana kutonhora kuchichinja.Zvichienderana nerudzi rwe thermistor, kuramba kwayo kunogona kuderera kana kuwedzera nekuwedzera tembiricha.Shanduko mukupikiswa kwe thermistor inotariswa nemagetsi edunhu, iyo, kana imwe tembiricha yasvika, inotumira masaini ekudzora kuti avhure, shandura kukurumidza kwekutenderera kana kudzima fan.
