Ndi zolakwa ziti zomwe ziyenera kuchitidwa panthawi yokonza firiji?

Momwe mungathetsere vuto la blockage mu firiji ndi nkhawa ya ogwiritsa ntchito ambiri. Kutsekeka mu firiji kumayamba makamaka chifukwa cha kutsekeka kwa mafuta, kutsekeka kwa ayezi kapena kutsekeka kwauve mu valavu ya throttle, kapena kutsekeka konyansa mu fyuluta yowumitsa. Lero ndikupatsani chidziwitso chatsatanetsatane chazomwe zimayambitsa komanso njira zothetsera kusokonekera kwadongosolo.

1. Kulephera kwa kutsekeka kwa mafuta

Chifukwa chachikulu chakutsekeka kwamafuta ndikuti silinda ya kompresa imavalidwa kwambiri kapena chilolezo cholumikizira silinda ndi yayikulu kwambiri. Mafuta otulutsidwa mu kompresa amatulutsidwa mu condenser, ndiyeno amalowa mu fyuluta yowumitsa pamodzi ndi refrigerant. Chifukwa cha kukhuthala kwakukulu kwa mafuta, amatsekedwa ndi desiccant mu fyuluta. Mafuta akakhala ochuluka, amatsekereza polowera zosefera, zomwe zimapangitsa kuti Refrigerant isayende bwino.

Mafuta owonjezera a firiji amakhalabe mufiriji, zomwe zimakhudza zotsatira za firiji kapena zimalepheretsa firiji. Choncho, mafuta a firiji mu dongosolo ayenera kuchotsedwa.
Momwe mungathanirane ndi kutsekeka kwa mafuta: Zosefera zikatsekeka, m'malo mwake ndi zina zatsopano, ndipo gwiritsani ntchito nayitrogeni wothamanga kwambiri pophulitsa gawo lina la mafuta a furiji omwe ali mu condenser. Ndi bwino kugwiritsa ntchito chowumitsira tsitsi kuti mutenthetse condenser pamene nitrogen imayambitsidwa.

Mwa njira, maukonde a firiji adzalankhula za filimu yamafuta pano. Chifukwa chachikulu cha filimu ya mafuta ndikuti mafuta opaka mafuta omwe sanasiyanitsidwe ndi olekanitsa mafuta adzalowa m'dongosolo ndikuyenda ndi refrigerant mu chubu, kupanga mafuta ozungulira. Pali kusiyana kwakukulu pakati pa filimu yamafuta ndi plug mafuta.

Kuopsa kwa filimu ya mafuta:

Ngati filimu yamafuta imamatira pamwamba pa chotenthetsera kutentha, kutentha kwa condensation kumakwera ndipo kutentha kwa evaporation kumatsika, zomwe zimapangitsa kuti mphamvu ziwonjezeke;

Pamene filimu yamafuta ya 0.1mm imayikidwa pamwamba pa condenser, mphamvu yoziziritsa ya compressor firiji imachepa ndi 16% ndipo kugwiritsa ntchito mphamvu kumawonjezeka ndi 12.4%;

Pamene filimu yamafuta mu evaporator ifika 0.1mm, kutentha kwa evaporation kumatsika ndi 2.5 ° C ndipo kugwiritsa ntchito mphamvu kumawonjezeka ndi 11%.

Njira yothetsera filimu ya mafuta:

Kugwiritsa ntchito mafuta ochulukirapo kumatha kuchepetsa kwambiri kuchuluka kwa mafuta omwe amalowa mupaipi yamagetsi;

Ngati filimu yamafuta ilipo kale m'dongosolo, imatha kuthiridwa ndi nayitrogeni kangapo mpaka palibe mpweya wonga nkhungu.

 

2. Kutsekereza kwa ayezindi kulephera

Kulephera kwa kutsekeka kwa ayezi kumachitika makamaka chifukwa cha chinyezi chambiri mufiriji. Ndi kufalikira kosalekeza kwa refrigerant, chinyezi mufiriji pang'onopang'ono chimakhazikika pakutuluka kwa valavu ya throttle. Popeza kutentha kwa valavu ya throttle ndikotsika kwambiri, mawonekedwe amadzi. Madzi oundana amawonjezeka ndipo pang'onopang'ono amawonjezeka. Pamlingo wina, chubu cha capillary chimatsekedwa kwathunthu ndipo firiji siyingayende.

Magwero akuluakulu a chinyezi:

Chinyezi chotsalira mu zigawo zosiyanasiyana ndi kulumikiza mapaipi a firiji dongosolo chifukwa chosakwanira kuyanika;

Mafuta a firiji ndi firiji amakhala ndi zochuluka kuposa kuchuluka kovomerezeka kwa chinyezi;

Kulephera kutsuka panthawi yoyika kapena kuyika molakwika kumabweretsa chinyezi;

Pepala lotsekera la mota mu kompresa lili ndi chinyezi.

Zizindikiro za ice blockage:

Kuthamanga kwa mpweya pang'onopang'ono kumakhala kofooka komanso kwapakatikati;

Pamene kutsekeka kuli kwakukulu, phokoso la kutuluka kwa mpweya limasowa, kuyendayenda kwa firiji kumasokonekera, ndipo condenser pang'onopang'ono imakhala yozizira;

Chifukwa cha kutsekeka, kuthamanga kwa mpweya kumawonjezeka ndipo kumveka kwa makina kumawonjezeka;

Palibe refrigerant yomwe imalowa mu evaporator, malo ozizira pang'onopang'ono amakhala ochepa, ndipo kuzizira kumakhala koipitsitsa;

Pambuyo pa nthawi yotseka, firiji imayamba kupangidwanso (madzi ozizira oundana amayamba kusungunuka)

Kutsekeka kwa ayezi kumapanga kubwereza bwereza kwa kutsukidwa kwakanthawi, kutsekedwa kwakanthawi, kutsekedwa kenako kutsukidwa, ndikutsukidwa ndikutsekedwanso.

Chithandizo cha Ice blockage:

Kutsekeka kwa ayezi kumachitika mufiriji chifukwa pali chinyezi chochulukirapo m'dongosolo, kotero kuti firiji yonse iyenera kuuma. Njira processing ndi izi:

Chotsani ndikusintha fyuluta yowumitsa. Pamene chizindikiro cha chinyezi pamawonekedwe a galasi la firiji chimasanduka chobiriwira, chimaonedwa kuti ndi choyenera;

Ngati madzi ochuluka alowa m'dongosolo, tsitsani nayitrogeni pang'onopang'ono, m'malo mwa fyuluta, sinthani mafuta a firiji, m'malo mwa firiji, ndikupukutani mpaka chizindikiro cha chinyezi chomwe chili m'galasi chisanduka chobiriwira.

3. Choyipa chotsekeka

Firiji ikatsekedwa, firijiyo sichitha kuyendayenda, zomwe zimapangitsa kuti kompresa azithamanga mosalekeza. Evaporator sizizira, condenser si yotentha, chipolopolo cha compressor sichiwotcha, ndipo palibe phokoso la kutuluka kwa mpweya mu evaporator. Ngati pali zonyansa zambiri mu dongosolo, chowumitsira fyuluta chidzatsekedwa pang'onopang'ono ndipo chophimba cha fyuluta cha makina otsekemera chidzatsekedwa.

Zifukwa zazikulu za kutsekeka kwauve:

Fumbi ndi zitsulo shavings yomanga ndi unsembe ndondomeko, ndi okusayidi wosanjikiza pamwamba khoma pamwamba kugwa pa chitoliro kuwotcherera;

Panthawi yokonza chigawo chilichonse, malo amkati ndi akunja sanatsukidwe, ndipo mapaipi sanali otsekedwa mwamphamvu ndipo fumbi linalowa m'mapaipi;

Mafuta a firiji ndi refrigerant amakhala ndi zonyansa, ndipo ufa wa desiccant mu fyuluta yowumitsa ndi woipa;

Zochita pambuyo pa kutsekeka kodetsedwa:

Ngati watsekeka pang'ono, mpweyawo umamva kuzizira kapena kuzizira, koma sipadzakhala chisanu;

Mukakhudza kunja kwa chowumitsira fyuluta ndi valavu ya throttle, zimamveka zoziziritsa kukhudza, ndipo padzakhala chisanu, kapena chisanu choyera;

The evaporator si ozizira, condenser si otentha, ndipo kompresa chipolopolo si otentha.

Kuthana ndi zovuta zotsekeka: Kutsekeka kwauve nthawi zambiri kumachitika mu fyuluta yowumitsa, fyuluta ya mesh ya throttling, suction fyuluta, ndi zina zotere. M'malo mwake akamaliza, firiji imafunika kuyang'anitsitsa ngati ikutulutsa ndikupukuta.
