Basa re fan mukutonhodza mvura

Kufambiswa kwekupisa kunoitwa panguva yekushanda kwemota kuenda kumhepo kunoda kugara kuchivhuvhuta kweradiator yeinotonhora system. Iko kusimba kwekuuya kwepamusoro-kumhanya kwemhepo kuyerera hakusi nguva dzose yakakwana kune izvi. Pakumhanya kwakaderera uye kumira kwakazara, imwe yakanyatsogadzirirwa yakawedzera kutonhora fan inouya.

Schematic dhizaini yejekiseni remhepo muradiator

Zvinogoneka kuve nechokwadi chekupfuura kwemazhinji emhepo kuburikidza nemuzinga wehuchi hweradiator munzira mbiri - kumanikidza mweya uchitevedza nzira yekuyerera kwechisikigo kubva kunze kana kugadzira vacuum kubva mukati. Iko hakuna mutsauko wakakosha, kunyanya kana system yezvivharo zvemhepo - diffusers inoshandiswa. Ivo vanopa hushoma hwekuyerera mwero wekusagadzikana kusina basa kwakatenderedza mashizha e fan.

Saka, pane maviri akajairika sarudzo dzekuronga kuvhuvhuta. Muchiitiko chekutanga, fan iri pane injini kana radiator furemu mukamuri yejini uye inogadzira kuyerera kuyerera kune injini, inotora mhepo kubva kunze uye ichipfuura kuburikidza neradiator. Kuti udzivise mashizha kubva pakushanda zvisina basa, nzvimbo iri pakati pe radiator uye impeller yakavharwa zvakasimba sezvinobvira nepurasitiki kana simbi diffuser. Chimiro chayo chinosimudzirawo kushandiswa kwenzvimbo yepamusoro yehuchi, sezvo dhayamita yefeni inowanzove idiki pane geometrical zviyero zveheatsink.

Kana iyo impeller iri kumberi kudivi, fan drive inogoneka chete kubva kune yemagetsi mota, sezvo redhiyeta musimboti unodzivirira mechanic kubatana neinjini. Muzviitiko zvese izvi, chimiro chakasarudzwa chedhishi yekupisa uye kutonhora kunodiwa kunogona kumanikidza kushandiswa kwekaviri feni ine madiki madhiyamita impellers. Iyi nzira inowanzo perekedzwa nekukanganisika kwealgorithm yekushanda, mafeni anokwanisa kuchinjika akaparadzana, achigadzirisa kuyerera kwemhepo zvichienderana nekuremerwa uye tembiricha.

Iyo fan impeller pachayo inogona kuve neyakaomarara uye aerodynamic dhizaini. Ine nhamba yezvinodiwa:

• iyo nhamba, chimiro, chimiro uye kukwirira kwema blades kunofanirwa kuve nekurasikirwa kushoma pasina kuunza imwe mari yesimba yekukuya kusina basa kwemhepo;
• mune imwe nzvimbo yakapiwa yekukurumidza kutenderera, kuyerera kwe stall hakubatanidzwi, kana zvisina kudaro kudonha kwekubudirira kuchakanganisa hurumende yekupisa;
• iyo fan inofanirwa kuve yakadzikama uye kwete kugadzira ese ari maviri mechanic uye aerodynamic vibrations anogona kurodha mabhengi uye ari padhuze injini zvikamu, kunyanya dzakatetepa radiator zvimiro;
• ruzha rwemapombi runoderedzwawo maererano nemaitiro akajairika ekudzikisa acoustic kumashure anogadzirwa nemotokari.

Kana tikaenzanisa mafeni emotokari emazuva ano nemapropeller ekare hafu yezana remakore rapfuura, saka tinogona kuona kuti sainzi yakashanda nemashoko ari pachena kudaro. Izvi zvinogona kuonekwa kunyange kunze, uye panguva yekushanda, fan yakanaka inenge yakanyarara inogadzira isingatarisirwi ine simba remhepo.

Fani drive mhando

Kugadzira kuyerera kwemhepo kwakanyanya kunoda huwandu hwakakosha hwesimba rekutyaira fan. Simba reizvi rinogona kutorwa kubva injini nenzira dzakasiyana.

Kuenderera mberi kutenderera kubva kune pulley

Mukutanga magadzirirwo akareruka, iyo fan impeller yaingoiswa pamvura pombi drive bhandi pulley. Kuita kwakapihwa nehupamhi hunoshamisa hwedenderedzwa remablades, ayo aingove akakotama mahwendefa esimbi. Kwakanga kusina kudiwa kworuzha, injini yekare yaiva pedyo yakadzora manzwi ose.

Kumhanya kwekutenderera kwakanyatso kuenderana nekuchinja kwe crankshaft. Chimwe chinhu chekudzora tembiricha chaivepo, nekuti nekuwedzera kwemutoro painjini, uye nekudaro kumhanya kwayo, fan yakatangawo kutyaira mweya kuburikidza neradiator zvakanyanya. Deflectors dzaisawanzoiswa, zvese zvakabhadharwa nemaradiator akawandisa uye huwandu hukuru hwemvura inotonhorera. Zvisinei, pfungwa yekupisa yainyatsozivikanwa kune vatyairi venguva iyoyo, kuva mutengo wekubhadhara kuti zvive nyore uye kusava nemafungiro.

Viscous couplings

Primitive masisitimu aive nezvakawanda zvakaipa:

• kutonhora kwakashata pakumhanya kwakaderera nekuda kwekuderera kwekumhanya kwekutyaira kwakananga;
• nekuwedzera kwehukuru hweimpeller uye shanduko yegiya regiyo kuti iwedzere kuyerera kwemhepo pakusaita, mota yakatanga kutonhora nekuwedzera kukurumidza, uye kushandiswa kwemafuta kwehupenzi kutenderera kwepropeller kwakasvika kukosha kwakakosha;
• apo injini yakanga ichidziya, feni yakaramba ichiomesa musoro kutonhorera injini, ichiita basa rakapesana chaizvo.

Zvaive pachena kuti kumwe kuwedzera kweinjini kushanda nesimba kwaizoda kukurumidza kudzora fan. Dambudziko rakagadziriswa kune imwe nhanho nenzira inozivikanwa muhunyanzvi sekubatanidza viscous. Asi pano inofanira kurongwa nenzira inokosha.

Iyo fan clutch, kana isu tichiifungidzira nenzira yakareruka uye tisingatarise shanduro dzakasiyana-siyana, ine maviri noted disks, pakati payo pane inonzi isiri-Newtonian fluid, kureva, silicone mafuta, inoshandura viscosity zvichienderana kukurumidza kufamba kwezvikamu zvayo. Kusvikira kuhutano hwakakomba pakati pe disks kuburikidza nejel viscous iyo ichatendeuka. Inoramba ichingoisa valve-sensitive valve ipapo, iyo ichapa iyi mvura mugomba nekuwedzera kwekushisa kwejini. Yakabudirira kwazvo dhizaini, zvinosuruvarisa, kwete nguva dzose yakavimbika uye yakasimba. Asi kazhinji kushandiswa.

Iyo rotor yakasungirirwa kune pulley inotenderera kubva ku crankshaft, uye impeller yakaiswa pane stator. Pakupisa kwepamusoro uye nekumhanya kwakanyanya, fan yakagadzira kuita kwakanyanya, kwaidiwa. Pasina kubvisa simba rakawandisa kana kuyerera kwemhepo kusingadiwi.

Magnetic clutch

Kuti urege kutambura nemishonga mukubatanidza iyo isingagadzi yakagadzikana uye yakasimba, mhinduro inonzwisisika kubva kune imwe nzvimbo yekugadzira magetsi inowanzoshandiswa. Iyo electromagnetic clutch ine friction discs ari mukubata uye anotenderedza kutenderera pasi pechiito chezvino chinopihwa kune electromagnet. Iyo yazvino yakabva kune yekudzora relay iyo yakavhara kuburikidza neyekushisa sensor, kazhinji yakaiswa pane radiator. Pakangoonekwa kusakwana kwemhepo, ndiko kuti, mvura iri muradiator yakawedzera kupisa, zvibatanidzi zvakavharwa, clutch yakashanda, uye impeller yakarukwa nebhandi rimwechete kuburikidza nemapulleys. Iyo nzira inowanzoshandiswa pamarori anorema ane mafeni ane simba.

yakananga yemagetsi drive

Kazhinji kazhinji, feni ine impeller yakanamirwa pamota shaft inoshandiswa pamotokari dzinotakura vanhu. Simba remagetsi eiyi mota rinopihwa nenzira imwecheteyo seyakatsanangurwa kesi ine clutch yemagetsi, chete V-belt drive ine pulleys haidiwi pano. Kana zvichidikanwa, mota yemagetsi inogadzira kuyerera kwemhepo, ichidzima pane yakajairika tembiricha. Iyo nzira yakashandiswa nekuuya kwema compact uye ane simba emagetsi mota.

Hunhu huri nyore hwedhiraivha yakadaro kugona kushanda neinjini yakamira. Masisitimu emazuva ano ekutonhora anoremerwa zvakanyanya, uye kana mhepo inoyerera ikangoerekana yamira, uye pombi isingashande, ipapo kupisa kwenzvimbo kunogoneka munzvimbo dzine tembiricha yakanyanya. Kana kufashaidza peturu muhuti system. Iyo fan inogona kumhanya kwechinguva mushure mekumira kudzivirira matambudziko.

Matambudziko, kukanganisa uye kugadzirisa

Kubatidza fan kunogona kutoonekwa seye emergency mode, sezvo isiri iyo fan inodzora tembiricha, asi thermostat. Naizvozvo, iyo inomanikidzwa mhepo inoyerera inogadzirwa yakavimbika kwazvo, uye haiwanzo kukundikana. Asi kana fan isingabatike uye mota ichivira, ipapo zvikamu zvinonyanya kutadza kukundikana zvinofanirwa kuongororwa:

• mune bhanhire rinotyaira, bhanhire rinogona kusunungura uye kutsvedza, pamwe nekuputsika kwayo kwakakwana, izvi zvose zviri nyore kuziva nekuona;
• iyo nzira yekutarisa iyo viscous coupling haisi nyore, asi kana ikatsvedza zvakanyanya pane inopisa injini, ichi chiratidzo chekutsiva;
• madhiraivha emagetsi, ese ari maviri clutch uye mota yemagetsi, anotariswa nekuvhara sensor, kana pajekiseni mota nekubvisa chinongedzo kubva kune tembiricha sensor yejini yekudzora system, feni inofanirwa kutanga kutenderera.

Fani yakashata inogona kuparadza injini, nokuti kupisa kwakanyanya kuzere nekugadzirisa kukuru. Nokudaro, hazvibviri kutyaira nezvikanganiso zvakadaro kunyange munguva yechando. Zvikamu zvakakundikana zvinofanira kuchinjwa pakarepo, uye chete zvikamu zvakasara kubva kumugadziri akavimbika zvinofanira kushandiswa. Mutengo wenyaya ndiyo injini, kana ichitungamirirwa nekushisa, ipapo kugadzirisa hakugoni kubatsira. Zvichipesana nemamiriro ezvinhu aya, mutengo we sensor kana mota yemagetsi unongo shaya basa.
