Momwe mungasinthire AC capacitor

AC condenser imalephera ngati makina oziziritsira mpweya ali ndi ma ducts otsekeka kapena kutayikira, kapena ngati mafani amagetsi a condenser asiya kugwira ntchito.

Ma capacitor a AC ndi gawo lofunikira la makina owongolera mpweya mgalimoto yanu. AC condenser imasamutsa kutentha kuchokera mufiriji kupita kumlengalenga ndipo motero imafanana ndi ntchito ya radiator mu injini yanu.

Umu ndi momwe zimagwirira ntchito: Refrigerant imapopedwa kuchokera ku A/C kompresa kupita ku condenser ngati mpweya wotentha. Mpweya womwe umadutsa mu zipsepse zoziziritsa za condenser umachepetsa kutentha kwa mpweya wotentha wa mufiriji, ndipo potero mpweya wa refrigerant "umasintha" kukhala madzi, omwe amayikidwa ndi valve mu evaporator mu kanyumba ka galimoto yanu. Mu evaporator, mufiriji wamadzimadziwa amayaka (zithupsa) kubwereranso kukhala nthunzi chifukwa amayamwa kutentha kuchokera mnyumba mwanu. Mpweya wokhala ndi kutentha umakokedwa ku mbali "yotsika" ya kompresa, yomwe imakanikiziranso mu condenser, kuyambitsanso kuzungulira kwa refrigerant.

Zitsanzo za zolakwika zomwe nthawi zambiri zimawonedwa mu ma capacitor a AC zimaphatikizapo kuwonongeka kwakunja kwa zipsepse kapena machubu, kuloza kutayikira, ndi ndime zomangika. Izi zikachitika, capacitor nthawi zambiri imayenera kusinthidwa (kupatula kuwonongeka kwakung'ono kwa zipsepse, zomwe zitha kuwongoleredwa ndi "chisa"). Nkhaniyi ifotokoza mwachidule njira yofunikira kuti mulowe m'malo mwa AC capacitor.

Gawo 3 la 3: Kuwunika komaliza, kuthamangitsidwa ndikutsitsanso

Zinthu zofunika

• Pampu yopuma

Gawo 1: Ikani AC System mu Vacuum. Musanawonjezeko firiji yatsopano, makina a AC ayenera kuyikidwa mu vacuum.

Izi zitha kuchitika pogwiritsa ntchito makina obwezeretsa kapena kugwiritsa ntchito makina ojambulira osiyanasiyana komanso pampu ya vacuum. Mizere yam'mbali yam'mwamba ndi yotsika iyenera kulumikizidwa ku pampu ya vacuum.

Dongosolo limayikidwa pansi pa vacuum kwa mphindi zosachepera 30, makamaka nthawi yayitali. Kutalika kwa nthawi yomwe dongosololi liyenera kukhala pansi pa vacuum zimadalira kutalika kwake ndi kuchuluka kwa chinyezi chomwe chimasunthidwa (ndicho chifukwa chake mukufunikira dehumidifier yatsopano - kuti chinyezi chikhale chochepa). FSM idzakulangizani za nthawi yomwe mukusamuka kuti mupange ndi chitsanzo chanu. Kusamutsidwa koyenera kumatsimikizira kuti chinyezi chonse ndi mpweya zimachotsedwa m'dongosolo lanu.

Pamene makina a AC ali pansi pa vacuum, mukhoza kudziwa ngati pali kudontha kwakukulu (dziwani kuti kukakamiza ndi nayitrogeni pafupifupi 200 psi kumawonetsa kutayikira kwakung'ono). Galimotoyo sichitha kutulutsa mpweya ngati galimoto ili ndi kutayikira kwakukulu. Pampu ya vacuum ipitilira kugwira ntchito, koma vacuum yovomerezeka sidzafikiridwa.

Ngati muthimitsa pampu ya vacuum kwa mphindi 10 ndikuwona kuthamanga kwa gauge, ndiye kuti pakapanda kutayikira kwakukulu, singano ya geji iyenera kukhala yokhazikika. Kupanda kutero, izi zikuwonetsa kutayikira komwe kumayenera kukonzedwa musanawonjezere firiji.

Komabe, ngati mukufunadi kuyesa kutayikira kwaukatswiri, kanikizani makinawo ku 200 psi ndi mpweya wowuma wa nayitrogeni, wowuma wa nayitrogeni ndi ma ounces angapo a firiji, kununkhiza potulutsa madzi pogwiritsa ntchito (mwachitsanzo) chowunikira cha Fieldpiece infrared refrigerant leak detector. Koma ngakhale kuyesaku sikuli koyenera, chifukwa mukuyesa pansi pazikhalidwe zosasunthika, osati zamphamvu (zogwira ntchito), pamene kutayikira kudzakhala koonekeratu.

Gawo 2 Malizitsani AC. Kachitidwe ka AC kakhala mu vacuum kwa mphindi 30 ndipo palibe kutayikira komwe kumadziwika kuti galimotoyo yakonzeka kulipitsidwa.

Makina amakono a AC ali ndi kuchuluka kwa ndalama zomwe zalembedwa mu magawo khumi a ounce. Chifukwa chake, makina oziziritsira mpweya sangagwire ntchito bwino kwambiri kaya ndi firiji yochulukira kapena yochepa kwambiri. Onetsetsani kuti mukugwiritsa ntchito firiji yomwe galimoto yanu inabwera nayo. Izi nthawi zambiri zimakhala R134a zamagalimoto amakono aku America opangidwa pambuyo pa zaka za m'ma 1990. Izi zitha kupezeka m'mabuku a eni ake kapena pa tagi ya A/C yomwe ili pansi pa hood.

Pomwe kuchuluka kwa refrigerant kuwonjezeredwa kwatsimikiziridwa, makina a AC angagwiritsidwe ntchito kulipiritsa dongosolo.

Kulipiritsa kumachitika ndi injini yomwe ikuyenda pa 1500 RPM kapena kupitilira apo ndipo ndi doko lotsika lokhalo lomwe limalumikizidwa. Dongosolo limadzazidwa mpaka ndalama zomwe zafotokozedwa (onani FSM kapena tag yapansi pagalimoto) yawonjezedwa. Ngati makina a AC agwiritsidwa ntchito ndalama zolipiritsa zitha kukhazikitsidwa, ngati mukugwiritsa ntchito manifold ndi gauge seti mulingo uyenera kukhazikitsidwa pogwiritsa ntchito sikelo kapena kutsika komanso kupanikizika kwambiri.

• Kupewa: Monga momwe zilili ndi njira zina zonse zomwe zili m'nkhaniyi, wogwiritsa ntchito firiji yemwe ali ndi chilolezo kapena katswiri wovomerezeka ndi amene ayenera kulipiritsa makina a AC. Izi ndi kupewa chindapusa chilichonse kapena, koposa zonse, kuwonongeka kwa chilengedwe kapena inu nokha chifukwa cha kusagwira bwino kwa firiji.

Gawo 3: Kuyang'ana Kachitidwe. Zokonza zonse zikamalizidwa ndipo makina owongolera mpweya wagalimoto alipiritsidwa, ndi nthawi yoti muwone ngati mapulani anu onse alipira, kusankha koyenera kwa zida zosinthira, kuyesa ndi kukonza.

Ndi injini ikuyenda, yatsani dongosolo la AC ndikulola kuti makinawo akhazikike kwa mphindi zisanu. Kusiyana pakati pa kutentha kwapakati (kutentha kwakunja) ndi kutentha kwa mpweya wozizira panyumba yanu yapakati kuyenera kukhala madigiri 5. Galimotoyo itazirala, izi zidzatsimikizira kuti choziziritsa mpweya chikugwira ntchito ndipo tsopano mutha kusangalala ndi kutentha kozizira.

Kusintha zigawo zikuluzikulu za AC system, monga capacitor, kungawoneke ngati ntchito yovuta, koma ikhoza kuchitidwa ndi chithandizo chochepa. Kukonzekera kumeneku kumalipira pakapita nthawi chifukwa sikumangokhalira kulekerera ndi A / C kuthamanga, koma dongosolo la AC lingathe kukutetezani ngati galimotoyo ikuphwanyidwa m'malo otentha.

Nthawi zina, zingakhale zosavuta kukonza izi kwa inu pamene mukupumula kunyumba kapena kuntchito. Mmodzi mwa makina akumunda a AvtoTachki adzakhala okondwa kubwera kunyumba kapena kuntchito ndikulowetsa capacitor.
