Compressor ndi makina ovuta kwambiri othamanga kwambiri. Kuonetsetsa kuti mafuta okwanira a compresshaft, mapepala, olumikizira, ma pisitoni ndi magawo ena osunthira ndiye chofunikira kwambiri kuti chisungidwe wamba pamakina. Pachifukwachi, opanga ma compressor amafunikira kugwiritsa ntchito magiredi opangira mafuta, ndipo amafuna kuyendera kwa mafuta ndi utoto wamafuta ndi utoto wopaka mafuta. Komabe, chifukwa chosanyalanyaza mu firiji kukhazikitsa dongosolo, zomanga ndi kukonza mafuta mu compressirir, kuphatikiza ndi kuwonongeka kwa mafuta, komanso kugwiritsa ntchito mafuta otsetsereka, ndi zina zambiri.
1. Mafuta osakwanira
Choyambitsa kuvala: mafuta osakwanira. Kuperewera kwa mafuta kumayambitsa mafuta osakwanira, koma mafuta osakwanira sikungoyambitsidwa chifukwa chosowa Mafuta.
Zifukwa zitatu zotsatirazi zingayambitsenso mafuta osakwanira:
Mafuta sangathe kukwaniritsa malo.
Ngakhale mafuta opangira mafuta afika pakukhala ndi zokulirapo, mawonekedwe ake ndi ochepa kwambiri kuti apange filimu yamafuta yokwanira.
Ngakhale mafuta opangira mafuta afika pachimake pa zomwe zalembedwazi, amawola chifukwa chotenthetsera komanso kusapanga mafuta.
Anayambitsa zotsatira zoyipa: Mafuta a Mafuta kapena Mafuta a Phatilo la Mafuta, etc. idzakhudzanso kuperekera mafuta odzola, ndipo mafuta odzola sangathe kufikira pampu ya mafuta. Ukonde wowotchera mafuta ndi pampu yamafuta ndizabwinobwino, koma kuvala zovala, chilolezo chowonjezera, chomwe chimapangitsa kuti mafuta a mafuta asakhale ovala, chifukwa cha ziwopsezo.
Chifukwa cha zifukwa zosiyanasiyana (kuphatikizapo gawo loyambira la compression), kutentha kwa thupi popanda kuthira mafuta kumawuka, ndipo mafuta odzola adzayamba kuwola atapitilira 175 ° C. "Kupanga Mafuta Ochepa - Kukangana Kwambiri - kutentha kwamphamvu kwambiri - kuwola kwa mafuta" ndi zochitika zambiri zolumikizira, kuphatikizapo kupanikizana rod kutseka ndikupsinjika, kumakhudzana ndi kuzungulira kumeneku. Mukasinthanitsa mu valavu ya valavu, yang'anani kuvala pini pipiki.
2. Kuperewera kwa mafuta
Kuperewera kwa mafuta ndi imodzi mwa zolakwa zosavuta kwambiri. Pamene compressor ndi yochepa kwambiri yamafuta, pali mafuta ochepa kapena osapaka mafuta mu crankcase.
Mafuta opangira mafuta otulutsidwa kuchokera ku compressor sabweranso: Compresser idzaperewera mafuta ngati mafuta odzola sabwerera.
Pali njira ziwiri zobwezera mafuta kuchokera ku compressor:
Imodzi ndi mafuta olekanitsa mafuta.
Wina ndi chitoliro chobwezeretsera mafuta.
Wolekanitsa wamafuta amaikidwa pa mapaipi omaliza a compression, omwe amatha kupatula 50-9% ya mafuta, omwe amachepetsa mafuta othamanga, pomwe amachepetsa opaleshoni popanda kubwereketsa mafuta osabweza. Kwa kayendedwe kozizira ka mufiriji makamaka, makina ozizira ozizira, ndi zida zouma zokhala ndi kutentha pang'ono, kuti compresser to reply itha kudutsa mafuta nthawi yayitali mutayamba. Kubwerera ku gawo la mafuta.
Mafuta opalekanitsa omwe sanalekanitsidwe adzalowa dongosolo: imayenda ndi firiji mu chitoliro kuti apange mawonekedwe a mafuta.
Pambuyo mafuta othilira atalowa mu Evaporator:
Kumbali imodzi, chifukwa cha kutentha kochepa komanso kusungunuka kochepa, gawo lopaka mafuta limalekanitsidwa ndi firiji.
Kumbali inayo, kutentha kumakhala kotsika ndipo mafuta owuma ndi osavuta kutsatira khoma lamkati la chitoliro, kumapangitsa kuti zikhale zovuta kuyenda.
Kuchepetsa kutentha kosinthanitsa, kovuta kwambiri kubwereza mafuta. Izi zimafuna kuti kapangidwe kake kamene kamapangidwe kwa mapaipi oyera komanso mapaisi obwerera kuyenera kukhala othandiza kuti mafuta abwerere. Njira yodziwika bwino ndikutengera kapangidwe ka mapaipi ndikuwonetsetsa kuti mulingo waukulu mpweya. Mwachitsanzo
Pamapulogalamu othandiza, mavuto obwezeretsera mafuta obwera chifukwa cha mapangidwe osayenera a Evaporators ndikubwezeretsa mizere yamlengalenga si yachilendo. Kwa R22 ndi R404a kachitidwe, Kubwezeretsa mafuta kwa Evaporator ndikovuta kwambiri, ndipo mapangidwe a njira yobwezera mafuta a System ayenera kusamala kwambiri. Kugwiritsa ntchito kudzipatula kwamafuta kwambiri kumatha kuchepetsa kwambiri kuchuluka kwa mafuta omwe akulowetsa dongosolo, nthawi yomweyo osabwezera mafuta mu chitoliro cha mpweya mutayamba.
Pamene compressor ili yapamwamba kuposa Evaporator Msampha wa Mafuta pa mzere wobwereza umafunikira. Pofuna kuonetsetsa kuti mafuta abwezeretse mafuta pansi, chitoliro cholumikizira chingatengere chopondera kawiri.
Kuyamba pafupipafupi kwa compressor sikuyenera kubweza mafuta. Chifukwa nthawi yopitilira ntchito ndiyochepa, Compressor imayima, ndipo palibe nthawi yopanga chitoliro chokhazikika chamtunduwu mu chitoliro cha mpweya, kotero mafuta odzola amatha kukhalabe mu chitoliro. Ngati mafuta obwerera ndi ochepera mafuta othamanga, Compresser idzaperewera mafuta.
Posankha, kutentha kwa Evapotor kumakwera, ndikuwoneka kuti mafuta opangira mafuta amachepetsa, kupangitsa kuti zikhale zosavuta kuyenda. Pambuyo pozungulira, firiji yotentha imakhala yokwera, ndipo mafuta opaka mafuta abwerera ku compresser. Pakakhala mitengo yambiri ya firiji, kuthamanga kwa mpweya kumachepa. Ngati kuthamanga kuli kotsika kwambiri, mafuta onunkhira adzakhala mu bomba lobwerera gasi ndipo sangathe kubwerera ku compresser mwachangu.
Chida cha mafuta otetezedwa chamafuta chimangoyima pomwe palibe mafuta kuteteza compresser kuti asawonongeke. palibe galasi lowoneka
Wophatikizidwa kwathunthu (kuphatikizapo rotor ndi scressers opondera) ndi zojambula zoponderezedwa ndi zida zotetezedwa ndi mafuta pomwe mafuta alibe, ndipo sadzasiya, ndipo sadzatha osazindikira.
PANGANI POPOSONKHA
3. Kumaliza
Choyambitsa mizu ya kusowa kwa mafuta sikochuluka komanso kuthamanga kwa compressor yomwe ikutha mafuta, koma mafuta osauka a dongosolo. Kukhazikitsa cholekanitsa mafuta kumatha kubwezeretsa mafuta mwachangu ndikukulitsa nthawi yopanga compressor popanda kubwereketsa mafuta. Mizere yobwezeretsa ndi kubwezeretsa iyenera kupangidwa ndi mafuta. Njira zosamalira monga kupewa zimayamba, kusungunuka kwa nthawi, kukonzanso mufiriji nthawi, ndikusintha zinthu zomwe zidavala piston pambuyo pake zimathandizanso kuti mafuta abwerenso.
Kubwezeretsa madzi Kubwereranso kuphika kumachepetsa mafuta owuma, omwe si omasuka pakupanga mafuta;
Kulephera kwa Mafuta ndi Kutchinga kwa Mafuta a Mafuta kudzakhudza mafuta ndi kuthamanga kwamafuta, chifukwa chosowa mafuta pamsinkhulidwe;
Kutentha kwakukulu kwa mikangano kumabweretsa kuwonongeka kwa mafuta opangira mafuta ndikupanga mafuta opangira mafuta kutaya mphamvu yake;
Mafuta osakwanira oyambitsidwa ndi mavuto atatuwa nthawi zambiri amayambitsa compressor. Zomwe zimayambitsa kusowa kwa mafuta ndi kachitidwe. Kungosintha compressor kapena zowonjezera zina sizingathetse vuto la kuchepa kwamafuta.
Chifukwa chake, kapangidwe kake ka dongosolo ndi mapaipi omanga zikuyenera kuganizira vuto lomwe limabwezedwa ndi madongosolo, apo ayi zidzakhala zovuta! Mwachitsanzo, pakupanga ndi kumanga, chitoliro cha Evaptorat Air Turn chimaperekedwa ndi chobwezeretsa mafuta, ndipo chitoliro chopopera chimaperekedwa ndi cheke. Mapaipi onse aziyenda pamadzi owongolerawo ndi njira yonse yotsika, yokhala ndi malo otsetsereka a 0.3 ~ 0,5%.
