Kodi cholumikizira chowoneka bwino ndi chiyani

Kulumikizana kwa viscous kwa fan yoziziritsa (kulumikizana kwa viscous fan) ndi chipangizo chotumizira ma torque, pomwe palibe kulumikizana kolimba pakati pa zinthu zoyendetsa ndi zoyendetsedwa.

Chifukwa cha izi:

• torque imatha kufalikira bwino komanso mofanana;
• kufala kwa torque kumasankha.

Kawirikawiri, kugwirizana kwa viscous (kugwirizanitsa mafani) ndi chinthu chodalirika chomwe chimakhala ndi moyo wautali wautumiki. Komabe, nthawi zina m'pofunika kufufuza operability ntchito, komanso m'malo kapena kukonza lumikiza. Werengani zambiri m'nkhani yathu.

Viscous coupling: chipangizo ndi mfundo ntchito

Kulumikiza kwa viscous fan (kulumikizana kwamadzi) ndi chipangizo chosavuta ndipo chimaphatikizapo zinthu zotsatirazi:

• nyumba zosindikizidwa;
• mawilo a turbine kapena ma discs mu casing;
• mawilo okhazikika pa zoyendetsa ndi zoyendetsedwa;
• Silicone fluid (expander) imadzaza danga pakati pa mawilo;

1. 1. Kawirikawiri, mitundu iwiri ikuluikulu ya ma viscous couplings imatha kusiyanitsa. Mtundu woyamba uli ndi nyumba, mkati mwake muli mawilo a turbine okhala ndi chowongolera. Gudumu limodzi limayikidwa pa shaft yoyendetsa ndipo linalo pa shaft yoyendetsa. Ulalo wolumikizana pakati pa mawilo a turbine ndi silikoni yamadzimadzi, yomwe ndimadzimadzi ogwira ntchito. Ngati mawilo azungulira pa liwiro losiyana, makokedwe amasamutsidwa ku gudumu loyendetsa, kuzungulira kwa mawilo kumalumikizidwa.
   2. Mtundu wachiwiri wa clutch umasiyana ndi woyamba kuti m'malo mwa mawilo, ma discs awiri omwe ali ndi zotsalira ndi mabowo amaikidwa pano. Pankhaniyi, ndi mtundu wachiwiri womwe nthawi zambiri umagwiritsidwa ntchito ngati chiwombankhanga chozizira. Ndi kasinthasintha kasinthasintha wa ma disc mkati mwa nyumba zowakira, madzimadzi a silicone samasakanikirana. Komabe, ngati kapoloyo ayamba kutsalira kumbuyo kwa mbuye wake, kusakaniza kumayambika. Pankhaniyi, madzi amasintha katundu wake (amakulitsa) ndikusindikiza ma disks motsutsana.
   3. Ponena za madzi omwe thupi la chipangizocho limadzazidwa, mfundo yonse yogwiritsira ntchito kugwirizana kwa viscous imachokera pa izo. Pakupuma, madzi amakhala viscous ndi madzimadzi. Mukayamba kutenthetsa kapena kusonkhezera, madziwo amakhala wandiweyani kwambiri ndipo amachulukirachulukira, kachulukidwe kake kamasintha, ngati mubweza madziwo pamalo opumira komanso / kapena kusiya kutentha, amakhalanso viscous ndi madzimadzi. Katundu wotere amakulolani kukanikiza ma diski wina ndi mnzake ndikuletsa kulumikizana kwa viscous, "kutseka" ma disc.

Kumene ma viscous couplings amagwiritsidwa ntchito m'galimoto

Monga lamulo, ma viscous couplings m'magalimoto amagwiritsidwa ntchito pamilandu iwiri yokha:

• kuzindikira kuziziritsa injini (kuzizira fan);
• gwirizanitsani magudumu onse (kutumiza).

Njira yoyamba ili ndi chipangizo chosavuta. Clutch yokhala ndi fan imakhazikika pa ndodo, yomwe imayendetsedwa ndi lamba kuchokera ku injini. Panthawi imodzimodziyo, kugwirizanitsa ma viscous pankhaniyi ndi odalirika kuposa mafani amagetsi, koma osagwira ntchito bwino.

Ponena za kuphatikizika kwa magudumu onse, ma crossovers ambiri amakhala ndi ma viscous coupling kuti azitha kuphatikiza ma gudumu onse. Panthawi imodzimodziyo, ziwombankhangazi tsopano zimasinthidwa pang'onopang'ono ndi mtundu wina mwa mawonekedwe a magetsi.

Chifukwa chachikulu ndikuti ma viscous couplings siosavuta kuwongolera (kwenikweni, amatha kutaya), komanso samatumiza makokedwe moyenera. Mwachitsanzo, magudumu anayi amayendetsedwa kudzera pa clutch pokhapokha mawilo akutsogolo akuzungulira kwambiri, pomwe palibe njira yokakamiza kukakamiza, etc.

Njira imodzi kapena imzake, ngakhale poganizira zofooka, ma viscous couplings ndi osavuta kupanga, otsika mtengo kupanga, okhazikika komanso odalirika. Avereji ya moyo wautumiki ndi zaka zosachepera 5, pamene muzochita pali magalimoto zaka 10 mpaka 15 ndi kuthamanga kuchokera 200 mpaka 300 Km, amene malumikizanidwe viscous ntchito bwino. Mwachitsanzo, dongosolo lozizira la zitsanzo zakale za BMW, kumene kuzizira kozizira kumakhala ndi chipangizo chofanana.

Momwe mungayang'anire kulumikizana kwa viscous

Kuwona kulumikizana kwa viscous kwa radiator yozizira si njira yovuta. Kuti muzindikire mwachangu, yang'anani kuzungulira kwa fani pa injini yotentha komanso yozizira.

Mukadzadzanso gasi, fani yotentha imazungulira mwachangu kwambiri. Pa nthawi yomweyi, injini ikazizira, liwiro silimawonjezeka.

Kufufuza mozama kwambiri kumachitidwa motere:

• Injini itazimitsa, tembenuzirani zowomba ndi dzanja. Kawirikawiri, kukana pang'ono kuyenera kumveka, pamene kusinthasintha kuyenera kukhala kosasunthika;
• Kenako, muyenera kuyambitsa injini, kenako phokoso laling'ono kuchokera pagulu lidzamveka mumasekondi oyamba. Patapita nthawi, phokosolo lidzatha.
• injini ikatenthedwa pang'ono, yesani kuyimitsa chowotcha ndi pepala lopindika. Kawirikawiri fani imayima ndipo mphamvu imamveka. Mukhozanso kuchotsa clutch ndikutentha poyiyika m'madzi otentha. Pambuyo pakuwotcha, sayenera kuzungulira ndi kukana mwamphamvu kuzungulira. Ngati clutch yotentha izungulira, izi zikuwonetsa kutayikira kwamadzimadzi opangidwa ndi silikoni.
• Pankhaniyi, m`pofunika fufuzani longitudinal chilolezo cha chipangizo. Kukhalapo kwa kubwezerana kotereku kumasonyeza bwino kuti kugwirizana kwa madzi a fan kuyenera kukonzedwa kapena kugwirizanitsa ma viscous kuyenera kusinthidwa.

Kukonzekera kwa viscous coupling

Kukachitika kuti galimoto inayamba kutenthedwa ndipo vuto likugwirizana ndi kugwirizana kwa viscous, mukhoza kuyesa kukonza. Zomwezo zikugwiranso ntchito pa drive clutch. Clutch sichinakonzedwe mwalamulo, madzimadzi a silicone sanasinthidwe, kunyamula sikunasinthidwe, etc.

Komabe, muzochita, kuwonjezera madzi oterowo kapena kusintha mayendedwe ndikotheka, zomwe nthawi zambiri zimalola kuti chipangizocho chizigwiranso ntchito. Choyamba muyenera kugula mafuta a viscous coupling oyenerera (mungagwiritse ntchito choyambirira kapena analogue) kapena mtundu waponseponse wamtundu wa viscous lumikiza kukonzanso madzimadzi.

Timalimbikitsanso kuwerenga nkhani yamomwe mungasinthire madzi owongolera mphamvu. Kuchokera m'nkhaniyi muphunzira nthawi yosinthira mafuta mu chiwongolero chamagetsi, ndi mafuta otani oti mudzaze chiwongolero chamagetsi, komanso momwe mungachitire nokha.

Apa mudzafunika:

1. Chotsani zowawa m'galimoto;
2. Chotsani chipangizocho;
3. Ikani kugwirizanitsa mozungulira ndikuchotsani pini pansi pa mbale ndi kasupe;
4. Pezani dzenje kuti mukhetse madzi (ngati sichoncho, dzipangireni nokha);
5. Pogwiritsa ntchito syringe, tsanulirani pafupifupi 15 ml yamadzimadzi mu khafu;
6. Madzi amatsanuliridwa m'magawo ang'onoang'ono (silicone iyenera kufalikira pakati pa ma disks);
7. Tsopano clutch ikhoza kukhazikitsidwa ndikuyikanso;

Ngati phokoso likumveka pakugwira ntchito kwa viscous coupling, izi zikuwonetsa kulephera kwapang'onopang'ono. Kuti m'malo viscous lumikiza kubereka, ndi silikoni madzimadzi choyamba chatsanulidwa (kenako kuthira mmbuyo pambuyo m'malo). Kenako diski yapamwamba imachotsedwa, chotengeracho chimachotsedwa ndi chokoka, chowotchacho chimapukutidwa mofanana ndipo chotengera chatsopano (chotsekedwa) chimayikidwa.

Ndikofunika kumvetsetsa kuti pochita maopaleshoni osiyanasiyana, muyenera kusamala kwambiri. Mwachitsanzo, ngakhale kupunduka pang'ono kwa clutch disc kungayambitse kulephera kwathunthu kwa chipangizocho. Komanso, musalole fumbi kapena dothi kulowa mkati mwa chipangizocho, musachotse mafuta apadera, ndi zina zotero.

 

Kusankha ndi kusintha kwa kugwirizana

Ponena za m'malo, m'pofunika kuchotsa chipangizo chakale ndikuyika chatsopano m'malo mwake, ndiyeno fufuzani ntchitoyo. M'zochita, zovuta zambiri zimachitika osati ndikusintha komweko, koma ndi kusankha kwa zida zosinthira.

Ndikofunikira kusankha mtundu wabwino wa viscous fan coupling kapena cholumikizira choyendetsa kuti chisinthidwe. Kuti muchite izi, muyenera kudziwa kachidindo ka gawo loyambira, kenako mutha kudziwa ma analogi omwe alipo m'mabuku. Mudzafunikanso VIN ya galimoto, kupanga, chitsanzo, chaka cha kupanga, ndi zina zotero kuti musankhe bwino magawo. Timalimbikitsanso kuwerenga nkhaniyi chifukwa chake injini imatenthedwa. M'nkhaniyi, muphunzira za zomwe zimayambitsa kutenthedwa kwa injini, komanso njira zopezera matenda ndi kukonza.

Popeza mwazindikira gawo lomwe likufunika, muyenera kulabadira wopanga. Poganizira kuti makampani ochepa okha ndi omwe amapanga ma viscous couplings, ndikwabwino kusankha pakati pa opanga otsogola: Hella, Mobis, Beru, Meyle, Febi. Monga lamulo, opanga omwewa amapanganso mbali zina (ma radiator ozizira, ma thermostats, mayunitsi oyimitsidwa, etc.).
