The air conditioning system ndi yotsekedwa.Kusintha kwanyengo kwa refrigerant m'dongosolo sikungawoneke kapena kukhudza.Pakakhala cholakwika, nthawi zambiri palibe poyambira.Chifukwa chake, kuti muweruze momwe dongosololi likugwirira ntchito, chida - gulu lamagetsi owongolera mpweya wagalimoto liyenera kugwiritsidwa ntchito.
Kwa ogwira ntchito yokonza ma air conditioning pamagalimoto, gulu loyezera kuthamanga ndilofanana ndi stethoscope ya dokotala ndi makina a X-ray fluoroscopy.Chida ichi chikhoza kupatsa ogwira ntchito yosamalira kuzindikira momwe zinthu zilili mkati mwa zipangizozo, ngati kuti zimapereka chidziwitso chamtengo wapatali chomwe chili chothandiza kuti azindikire matendawa.
Kugwiritsa ntchito manifold pressure gauge pagalimoto yama air conditioner
Tube pressure gauge ndi chida chofunikira pakusunga makina owongolera mpweya wamagalimoto.Zimalumikizidwa ndi firiji kuti zisungunuke, kuwonjezera refrigerant ndikuzindikira zolakwika za firiji.Gulu la pressure gauge lili ndi ntchito zambiri.Itha kugwiritsidwa ntchito kuyang'ana kuthamanga kwa dongosolo, kudzaza dongosolo ndi refrigerant, vacuum, kudzaza dongosolo ndi mafuta opaka, etc.
Mapangidwe a magulu ochuluka a pressure gauge
Kapangidwe kake kakakulu koyesa kukakamiza kosiyanasiyana kumapangidwa makamaka ndi miyeso iwiri yoyezera (kutsika kwapakati komanso kutsika kwamphamvu), ma valve awiri apamanja (ma valve otsika otsika ndi ma valve othamanga kwambiri) ndi ma payipi atatu.Mageji okakamiza onse ali pagawo limodzi, ndipo pali njira zitatu zolumikizira kumunsi.Kuyeza kwamphamvu kumalumikizidwa ndikulekanitsidwa ndi dongosolo kudzera mu ma valve awiri apamanja.
Mavavu am'manja (LO ndi HI) amayikidwa pamunsi pa mita kuti azipatula njira iliyonse kapena kupanga mapaipi osiyanasiyana ophatikizika okhala ndi mavavu amanja ngati pakufunika.
Kupimidwa kochulukira kochulukira kumakhala ndi zida ziwiri zoyezera kuthamanga, imodzi imagwiritsidwa ntchito kuti izindikire kupanikizika kwapamwamba pagawo la firiji, ndipo inayo imagwiritsidwa ntchito pozindikira kupanikizika kwapang'onopang'ono.
Chiyerekezo chotsika chotsika chapakatikati chimagwiritsidwa ntchito kuwonetsa kupanikizika komanso digiri ya vacuum.Kuwerengera kwa digiri ya vacuum ndi 0 ~ 101 kPa.Kupanikizika kumayambira pa 0 ndipo kuyeza kwake sikuchepera 2110 kPa.Kuthamanga kosiyanasiyana koyezedwa ndi kutsika kwamphamvu kwapakati kumayambira pa 0, ndipo kuchuluka kwake sikuyenera kuchepera 4200kpa.Vavu yamanja yolembedwa ndi "Lo" ndi valve yomaliza yotsika, ndipo "Hi" ndi valve yomaliza yothamanga kwambiri.Chipilala cholembedwa ndi buluu ndi choyezera chotsika, chomwe chimagwiritsidwa ntchito kuyeza kuthamanga ndi vacuum.Kuwerenga kokulirapo kuposa ziro molunjika ndiko kuchuluka kwa mphamvu, ndipo kuwerengera kwakukulu kuposa ziro motsatana ndi koloko ndi sikelo ya vacuum.Mamita omwe amalembedwa mofiira ndi mita yamphamvu kwambiri.
