Kodi ntchito ya compressor ya galimoto ndi yotani?
Chokometsera mpweya woziziritsa magalimoto ndiye maziko a makina oziziritsira mpweya, omwe amagwira ntchito yopondereza ndi kutumiza nthunzi ya firiji. Ma compressor amagawidwa m'magulu awiri: kusuntha kosasinthika ndi kusuntha kosinthika.
Kutengera mfundo zosiyanasiyana zogwirira ntchito, ma compressor oziziritsa mpweya amatha kugawidwa m'ma compressor okhazikika komanso osinthasintha.
Chokometsera chosasinthika
Kusuntha kwa compressor yosinthika mokhazikika kumawonjezeka mofanana ndi kuwonjezeka kwa liwiro la injini. Singathe kusintha mphamvu yokha malinga ndi kufunikira kwa kuziziritsa ndipo kumakhudza kwambiri kugwiritsa ntchito mafuta a injini. Kulamulira kwake nthawi zambiri kumachitika posonkhanitsa chizindikiro cha kutentha kuchokera ku evaporator outlet. Kutentha kukafika pamtengo wokhazikika, compressor electromagnetic clutch imatulutsa, ndipo compressor imasiya kugwira ntchito. Kutentha kukakwera, electromagnetic clutch imagwira ntchito, ndipo compressor imayamba kugwira ntchito. Compressor yosinthika mokhazikika imawongoleredwanso ndi kuthamanga kwa makina oziziritsira mpweya. Kupanikizika mupayipi kukakwera kwambiri, compressor imasiya kugwira ntchito.
Chokometsera mpweya chosinthasintha
Chokometsera chosinthasintha chimatha kusintha mphamvu yotulutsa yokha malinga ndi kutentha komwe kwayikidwa. Dongosolo lowongolera mpweya silitenga chizindikiro cha kutentha kuchokera ku evaporator outlet koma limawongolera chiŵerengero cha compressor cha compressor kutengera chizindikiro chosintha kupanikizika mu payipi yoziziritsira mpweya kuti chisinthe kutentha kwa kutuluka. Panthawi yonse yozizira, compressor imagwira ntchito nthawi zonse, ndipo kusintha kwa mphamvu yoziziritsira kumayendetsedwa kwathunthu ndi valavu yowongolera kupanikizika yomwe imayikidwa mkati mwa compressor. Pamene kupanikizika kumapeto kwa kupanikizika kwakukulu kwa payipi yoziziritsira mpweya kuli kwakukulu kwambiri, valavu yowongolera kupanikizika imafupikitsa kugwedezeka kwa pistoni mu compressor kuti ichepetse chiŵerengero cha kupsinjika, motero imachepetsa mphamvu yoziziritsira. Pamene kupanikizika kumapeto kwa kupanikizika kwakukulu kumatsika kufika pamlingo winawake ndipo kupsinjika kumapeto kwa kupsinjika kochepa kumakwera kufika pamlingo winawake, valavu yowongolera kupanikizika imawonjezera kugwedezeka kwa pistoni kuti iwonjezere mphamvu yoziziritsira.
Kulephera kwa compressor ya mpweya woziziritsa mpweya kungayambitsidwe ndi zifukwa zosiyanasiyana monga ma circuits, refrigerant, ndi mechanics. Njira yokonza mavuto mwadongosolo komanso pang'onopang'ono imafunika. Zolakwika zambiri za m'deralo (monga clutch, kuwonongeka kwa coil) zimatha kukonzedwa pamtengo wotsika popanda kusintha compressor yonse.
Zomwe Zimayambitsa Vuto Lofala
Kulephera kwa dongosolo la dera: Ichi ndiye chifukwa chofala kwambiri komanso chosavuta kuthetsa. Fuse ya mpweya woziziritsa ikaphulika, relay yawonongeka, kapena pulagi ya waya yatayikira/yadzimbiri, zomwe zingayambitse kuti compressor itaye mphamvu.
Kusakhazikika kwa mphamvu ya firiji ndi kuthamanga kwa mpweya: Pamene kutayikira kwa mphamvu ya firiji kupangitsa kuti mphamvu ya makina ikhale yotsika kwambiri, chotchingira choteteza mphamvu ya mpweya chotsika chimadula mphamvu ya compressor; kuthamanga kwambiri kumayambitsa chitetezo cha mphamvu ya mpweya. Ngati firiji sikokwanira, kubwerera kwa mafuta a firiji kumachepa, ndipo kungayambitsenso kuti compressor isadye mafuta okwanira komanso kuti iwonongeke.
Kulephera kwa makina:
Kulephera kwa clutch yamagetsi: Chophimba cha clutch chimatha, chikho chokokera chimatha kapena mpata wake siwoyenera (mtengo wokhazikika nthawi zambiri umakhala 0.35-0.50mm), zomwe zingayambitse clutch kulephera kugwirana kapena kutsetsereka.
Vuto la lamba wopatsira: Lamba ndi lomasuka kwambiri ndipo limatsetsereka, kapena lolimba kwambiri ndipo lingayambitse compressor kutsekeka.
Kuwonongeka kwa mkati mwa compressor: Kusowa kwa mafuta kwa nthawi yayitali, zinyalala zomwe zimalowa, kapena kugwira ntchito mopitirira muyeso kungayambitse kuwonongeka ndi kumamatira kwa zigawo zamkati monga ma bearing ndi ma piston, komwe ndi mtundu wovuta kwambiri wa kulephera.
Kulephera kwa sensa kapena gawo lowongolera: Zolakwika mu sensa ya mpweya woziziritsa, sensa ya kutentha kwamkati, kapena gawo lowongolera mpweya (ECU) zingayambitse dongosololi kuweruza molakwika ndikulamula compressor kuti iyime.
Zizindikiro Zolakwika
Kuchepa kwakukulu kapena kutayika kwathunthu kwa mphamvu yozizira: Ichi ndi chiwonetsero chodziwikiratu kwambiri.
Compressor sigwira ntchito: Mukadina batani la AC, palibe phokoso la "click" la clutch lomwe likugwira ntchito mu injini, ndipo pulley ya compressor imazungulira yopanda kanthu.
Phokoso losazolowereka: Kukangana kwachitsulo, kugogoda, kapena "kumveka kotentha" kumachitika panthawi yogwira ntchito, zomwe zingasonyeze kuwonongeka kwa makina mkati kapena kutsika kwa clutch.
Kupanikizika kosazolowereka kwa dongosolo: Poyesa ndi choyezera cha akatswiri, kuthamanga kwapamwamba ndi kotsika kumatha kukhala kotsika kwambiri nthawi imodzi (kusowa kwa refrigerant), kokwera kwambiri, kapena kotsika kwambiri.
Kutuluka kwa mafuta kapena madontho a mafuta owoneka: Madontho a mafuta amawonekera pamalo olumikizirana mapaipi, ma condenser, ndi zina zotero, zomwe zikusonyeza kuti mafuta oziziritsa (omwe ali ndi mafuta oziziritsa) akutuluka.
Tsatirani njira yopezera mavuto pang'onopang'ono kuyambira yosavuta mpaka yovuta:
Kuyang'ana Koyamba: Tsimikizani kuti kiyi ya AC yayatsidwa ndipo voliyumu ya mpweya ndi yokwanira; mvetserani mawu okoka ndi ogwirira ntchito kuchokera ku compressor; yang'anani ma fuse ndi ma relay a air conditioner (kuti muyesedwe mosinthana).
Kuzindikira Kwapamwamba: Gwiritsani ntchito choyezera kuthamanga kwa mpweya kuti muzindikire kuthamanga kwa makina; yang'anani kupsinjika kwa lamba wotumizira; yang'anani kutseguka kwa clutch ndi kukana kwa coil.
Kukonza Katswiri: Ngati njira zomwe zili pamwambapa sizikugwira ntchito, kungakhale kofunikira kugwiritsa ntchito chida chowunikira kuti muwerenge ma code olakwika, kapena kufunsa katswiri waluso kuti awone momwe makinawo alili mkati.
Ntchito zokhudzana ndi refrigerant zimafuna kusamalidwa ndi akatswiri: Kuzindikira kutuluka kwa madzi ndi kubwezeretsanso refrigerant kuyenera kuchitika pogwiritsa ntchito zida zaukadaulo ndikuwonjezedwa mogwirizana ndi miyezo yamanja ya galimoto. Musasakanize mitundu yosiyanasiyana ya refrigerant (monga R134a ndi R1234yf).
Mukasintha compressor, ndikofunikira kusunga makinawo nthawi imodzi: Ngati pakufunika kusintha compressor, botolo lowumitsira liyeneranso kusinthidwa ndipo mapaipi ayenera kutsukidwa kuti zinyalala zisawononge zigawo zatsopano.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
