Bwerani mudzadziwe za nkhanizi zokhudzana ndi mafuta kufinya.

Vuto la Mafuta Kubwezeretsa Mafétressions kwakhala mutu wotentha munjira firiji. Masiku ano, ndilankhula za vuto lobwezera mafuta la compressors. Nthawi zambiri, chifukwa chomwe mafuta osauka amabwerera compressor amasakaniza mpweya wosakaniza wa shenomenon wamafuta ndi firiji pakugwiritsa ntchito. Pa nthawi ya ntchito ya firiji ya firiji, mufiriji ndi mafuta opangira mafuta a firiji ndi kusungunuka mafuta kuti atulutsidwe mu mawonekedwe a aerosol ndi masitima a makinawo ndi firiji. Ngati olekanitsa mafuta siagwira ntchito kapena dongosolo la makina siabwino, lidzapangitsa kuti khungu likhale losavomerezeka komanso kubwezeretsanso mafuta.

1. Ndi mavuto ati omwe azidzachitika chifukwa cha kubwerera kwa mafuta:

Mafuta osauka a compresser amayambitsa mafuta ambiri kuti akhale mu Pipe. Makanema a mafuta atachulukanso pamlingo winawake, zimakhudza mwachindunji kuzizira kwa dongosololo; Zidzapangitsa kuti mafuta ambiri azikhala ndi mafuta ambiri m'dongosolo, zomwe zimapangitsa kuti pakhale ndalama zogwirira ntchito, zimawononga ndalama komanso kuchepetsa kudalirika. Nthawi zambiri, osakwana 1% ya kutuluka kwa mpweya woyenera kumaloledwa kumazungulira mu kachitidwe kamene kamakhala ndi mpweya.

2. Mayankho a Kubwerera Kwamafuta:

Pali njira ziwiri zobwezera mafuta ku compression, imodzi ndikubwezera mafuta kuti akhale olekanira kwa mafuta, ndipo winayo ndikubwezera mafuta kuti abwerere chitoliro cha mpweya.

Olekanitsa mafuta amaikidwa pa chitoliro cha compressor, chomwe chimasiyananso ndi mafuta okwanira 50-9% ya mafuta othamanga. Kusintha kwa mafuta ndikwabwino ndipo kuthamanga kumachepetsa kwambiri, komwe kumachepetsa kuchuluka kwa mafuta omwe akulowetsa dongosolo, motero amapitilira opaleshoni popanda kuwunika mafuta. nthawi.

Kwa makina ozizira osungirako firiji okhala ndi makina oundana ozizira, ndi zida zotentha zokhala ndi kutentha pang'ono, sizachilendo kubwereketsa mafuta kwa mphindi khumi kapena ngakhale pang'ono mutayamba makinawo. Dongosolo loipa lidzayambitsa compresser kuti mutseke chifukwa cha kuthamanga kwa mafuta. Kukhazikitsa kwa olekanitsidwa ndi mafuta okwera kwambiri mu firiji iyi kungakuthandizeni kwambiri ntchito ya compressor popanda kubwereketsa mafuta, kuti compressor ithe kudutsa bwino pagawo lililonse la magetsi pambuyo poyambira. Mafuta opaka omwe samalekanitsidwa adzalowa mu dongosolo ndikuyenda ndi firiji mu chubu kuti apange magazi.

Pambuyo mafuta othilira mafuta atalowa mu Evaporator, chifukwa cha kutentha kochepa komanso kususuka kochepa, gawo la mafuta opangira mafuta limalekanitsidwa ndi firiji; Kumbali inayo, kutentha kumakhala kotsika ndipo mafuta owuma ndi osavuta kutsatira khoma lamkati la chubu, ndipo ndikovuta kuyenda. Kutentha kwambiri kwa kutentha, ndizovuta kwambiri kubwezeretsa mafuta. Izi zimafuna kuti kapangidwe kake kamene kamapangidwe kwa mapaipi oyera komanso mapaisi obwerera kuyenera kukhala othandiza kuti mafuta abwerere. Njira yodziwika bwino ndikugwiritsa ntchito kapangidwe ka masipu ndikuwonetsetsa kuti mulimbikitso lalikulu. Mwachitsanzo

Pamapulogalamu othandiza, mavuto obwezeretsera mafuta obwera chifukwa cha mawonekedwe osayenera a Evaporator ndikubwezera masitepe gasi sizachilendo. Kwa R22 ndi R404A makina, amabwezeretsa mafuta osefukira ndizovuta kwambiri, ndipo makina obwezera mafuta a Mafuta ayenera kusamala kwambiri. Kwa dongosolo lotere, kugwiritsa ntchito malo olekanitsidwa ndi mafuta kwambiri kumatha kuchepetsa kuchuluka kwa mafuta omwe amalowa mu specinelo, nthawi yomweyo chitoliro chobwerera gasi sichikubwezera mafuta atayamba makinawo.

Pamene compressor ili yapamwamba kuposa evaporator, kubweza mafuta kukhazikika pa chitoliro chobwereza chikuyenera. Msampha wobwezeretsedwayo uyenera kukhala wophatikizika momwe angathere kuti achepetse mafuta. Kutalikirana pakati pa mafuta kumayenera kukhala koyenera. Pamene kuchuluka kwa magetsi kumalumikizana ndi kwakukulu, mafuta ena opangira mafuta ayenera kuwonjezedwa. Chisamaliro chikuyeneranso kutengedwa m'magulu obwerera ku makina osinthika. Katunduyu akachepetsedwa, kuthamanga kwa mpweya kumatsika, ndipo liwiro lake ndi lotsika kwambiri, lomwe silobwezeretsanso mafuta. Pofuna kuonetsetsa kuti mafuta abwezeretse mafuta pansi, chitoliro chokhazikika chimatha kugwiritsa ntchito riser iwiri.

Kuphatikiza apo, chiyambi pafupipafupi cha compressor sichothandiza kuti mafuta abwerere. Chifukwa nthawi yopitilira ntchito ndiyochepa, Compressor imayima, ndipo palibe nthawi yopanga mpweya wokhazikika mkutu wobwerera, kotero mafuta odzola amatha kukhala pa mapaipi. Ngati mafuta obwerera ndi ochepera kuposa omwe amayenda, Compressor adzaperewera mafuta. Chifupi nthawi yomwe ikuyenda, pomwepo mapaipi, dongosololi lovuta kwambiri, lomwe limadziwika kwambiri kuti vuto la mafuta limabweza. Chifukwa chake, nthawi zina, musayambire compresser pafupipafupi.

Kuperewera kwa mafuta kumayambitsa kusowa kwamafuta kwambiri. Choyambitsa mizu yoperewera mafuta si zochuluka kwambiri komanso kuchuluka kwa compressor kuthamanga, koma mafuta osauka a dongosolo. Kukhazikitsa cholekanitsa mafuta kumatha kubwezeretsa mafuta mwachangu ndikuwonjezera ntchito ya compressor popanda kubwereketsa mafuta. Kapangidwe ka Hulporator ndi mzere wobwereza ziyenera kutenga mafuta kuti abwezeretse mafuta. Njira yokonza monga kupewa kulowetsedwa pafupipafupi, kusungunuka pafupipafupi, kukonzanso kufinya nthawi, ndikusintha maofesi (monga maofesi) nthawi yobwereranso mafuta.

Mukamapanga dongosolo la firiji, kafukufuku yemwe amabwezeretsanso magazi ndi ofunikira. Pokhapokha poganiza mbali zonse, zitha kukhala zodalirika komanso firiji yodalirika.
