Kugwira ntchito kwa zida zodziwira kutayikira kwa ma air conditioner apagalimoto
Zipangizo zodziwikiratu zomwe zatsikira zimagwiritsidwa ntchito poyang'ana ngati firiji mu makina oziziritsa mpweya akutha.
Refrigerant ndi chinthu chosavuta kusuntha.M'mikhalidwe yabwinobwino, kuwira kwake ndi -29.8 ℃.
Choncho, ndondomeko yonse ya firiji imayenera kusindikizidwa bwino, apo ayi, firiji idzadumpha ndikusokoneza ntchito ya firiji.
Choncho, m'pofunika nthawi zonse kufufuza refrigeration dongosolo kwa kutayikira.Pambuyo pochotsa kapena kukonzanso mapaipi a makina owongolera mpweya wamagalimoto ndi firiji ndikusintha magawo, kuwunika kwa kutayikira kudzachitika pakukonzanso ndi kugawa magawo.
Chida chodziwira kutayikira chimagwiritsidwa ntchito kuwunika ngati firiji mu makina owongolera mpweya akutha.Refrigerant ndi chinthu chosavuta kutulutsa nthunzi, pansi pazikhalidwe zabwinobwino, kuwira kwake ndi -29.8 ℃.Choncho, ndondomeko yonse ya firiji imayenera kusindikizidwa bwino, mwinamwake firiji idzatuluka, zomwe zimakhudza ntchito ya firiji.Choncho, m'pofunika kufufuza refrigeration dongosolo kwa kutayikira.Pamene disassembling kapena kukonza mapaipi a galimoto mpweya mpweya refrigeration dongosolo ndi m'malo mbali, kutayikira anayendera ayenera kuchitidwa pa kukonza ndi disassembly mbali.Zipangizo zamagalimoto zamagalimoto zomwe zimagwiritsidwa ntchito nthawi zambiri zimazindikira kutayikira: zida zodziwira kutayikira kuphatikiza nyali ya halogen kutayikira, chowunikira utoto, chowunikira chowunikira cha fulorosenti, chowunikira chamagetsi, chowunikira cha helium mass spectrometry leak, ultrasonic leak detector ndi zina zotero.Nyali yodziwikiratu ya halogen ingagwiritsidwe ntchito pa R12, R22 ndi kuzindikira kwina kwa halogen refrigerant.
Zida zodziwika bwino zodziwira kutayikira kwa makina owongolera mpweya wamagalimoto ndi monga
Zida zodziwira zotayikira zimaphatikizanso chowunikira cha halogen leak, chowunikira utoto, chowunikira cha fulorosenti, chowunikira chamagetsi, chowunikira cha helium mass spectrometer leak, ultrasonic leak detector, etc.
Nyali yodziwira kutayikira kwa halogen ingagwiritsidwe ntchito pozindikira kutuluka kwa mafiriji a halogen monga R12 ndi R22, ndipo ilibe mphamvu pamafiriji atsopano monga R134a opanda ma chloride ayoni.
Chowunikira chamagetsi chamagetsi chimagwiranso ntchito ndi mafiriji wamba, omwe ayenera kutsatiridwa pakugwiritsa ntchito.
Njira yodziwira kutayikira kwa nyali ya halogen
Mukamagwiritsa ntchito nyali ya halogen, njira yogwiritsira ntchito iyenera kuwonedwa mosamalitsa.Lawi litasinthidwa moyenera, lolani chitoliro choyamwa pakamwa pafupi ndi gawo lomwe lapezeka, muwone kusintha kwamtundu wamoto, ndiye kuti titha kuweruza momwe kutayikira.Gome lakumanja likuwonetsa momwe zinthu zimayendera kukula kwa kutayikira ndi mtundu wamoto.

Chidacho chimapangidwa ndi mfundo yofunikira kuti mpweya wa halide umalepheretsa kutulutsa koyipa kwa corona.Mukamagwiritsa ntchito, ingowonjezerani probe ku gawo lomwe lingatayike.Ngati pali kutayikira, belu la alamu kapena kuwala kwa alamu kudzawonetsa chizindikiro chofananira malinga ndi kuchuluka kwa kutayikira.
Positive pressure leak njira yodziwira
Dongosololi litakonzedwa ndipo musanadzaze ndi fluorine, kagawo kakang'ono ka gaseous fluorine kadzadzalidwa poyamba, ndiyeno nayitrogeni imadzazidwa kuti ikakamize dongosolo, kotero kuti kupanikizika kumafika 1.4 ~ 1.5mpa ndipo kupanikizika kumasungidwa kwa 12h.Kuthamanga kwa gauge kutsika kuposa 0.005MPa, zikuwonetsa kuti makinawo akutsika.Choyamba, kuyang'ana mwaukali ndi madzi a sopo, ndiyeno kuyang'ana bwino ndi nyali ya halogen kuti mudziwe malo omwe atayikira.
Njira yodziwira kutayikira kwa Negative pressure
Chotsani makina, sungani kwa nthawi ndithu, ndipo muwone kusintha kwa mphamvu ya vacuum gauge.Ngati digiri ya vacuum itsika, zikuwonetsa kuti dongosolo likutuluka.
Njira ziwiri zomalizazi zitha kuzindikira ngati dongosolo likutha.Njira zisanu zoyambirira zimatha kuzindikira malo enieni a kutayikira.Njira zitatu zoyambirira ndizowoneka bwino komanso zosavuta, koma mbali zina ndizosautsa kuyang'ana ndikutsata kutayikira sikophweka kuzizindikira, kotero zimangogwiritsidwa ntchito ngati kuyendera movutikira.Chowunikira cha halogen leak ndi chovuta kwambiri ndipo chimatha kuzindikira pamene choziziritsa chikutsika kupitirira 0.5g pachaka.Koma chifukwa cha kutayikira kwa refrigerant kuzungulira dongosolo danga angathenso kuyeza, adzaona molakwika kutayikira malo ndi chida ndi okwera mtengo, okwera mtengo, zambiri osati ntchito.Ngakhale kuyang'ana kwa nyali ya halogen kumakhala kovuta pang'ono, ndi komwe kumagwiritsidwa ntchito kwambiri chifukwa cha mawonekedwe ake osavuta, mtengo wotsika komanso kulondola kwapamwamba.
