A, indima yamafutha okugcoba:
1) esikulufini nasegumbini lokucindezela kanye naphakathi kwesikulufini se-yin ne-yang ukuze kwakheke uphawu oluguquguqukayo, nciphisa isiqandisi enqubweni yokucindezela kusukela ohlangothini lokucindezela okuphezulu kuya ohlangothini lokucindezela oluphansi lokuvuza.
2) ukupholisa i-refrigerant ecindezelwayo, uwoyela ufafazwa ku-compressor, umunce ukushisa okukhiqizwa yigesi ye-refrigerant enqubweni yokucindezela, kunciphisa izinga lokushisa lokukhipha umoya.
3) Ebhereni nasesikulufini phakathi kokwakheka kwefilimu kawoyela ukusekela i-rotor, futhi idlala indima ekugcobeni.
4) Dlulisa amandla okucindezela okuhlukile, shayela uhlelo lokulungisa umthamo, ngesenzo sokukhipha nokufaka i-valve ye-solenoid ye-compressor, ulungise indawo yesilayida sokulungisa umthamo, ukuze ufinyelele ukulawula kokulungiswa kwamandla e-compressor.
5) Nciphisa umsindo wokusebenza
Incazelo:
I-compressor yangaphakathi yokuthambisa iyisihluthulelo sokugcina ukusebenza okuvamile kwe-compressor, izinkinga ezijwayelekile zokuthambisa yilezi:
1) izinto zangaphandle ezixubene, okuholela ekugcotshweni kwamafutha, okuvimba isihlungi samafutha.
2) Umphumela wokushisa okuphezulu ubangela ukuthi i-lubricant yonakale futhi ilahlekelwe umsebenzi we-lubricant.
3) Ukungcoliswa kwamanzi ohlelweni, ukwakheka kwe-asidi, ukuguguleka kwenjini.
Okwesibili, ukuhlolwa nokushintshwa kwamafutha okuqandisa i-compressor:
Kumkhiqizi wesistimu, ukuhlolwa kanye nomjikelezo wokushintsha uwoyela wokuqandisa we-compressor kuhlobene nokulawulwa kwenqubo yenqubo yawo yokukhiqiza. Uma ukulawulwa kokuhlanzeka kwe-evaporator kanye ne-condenser yesistimu kanye namapayipi esistimu kuhle kakhulu, khona-ke ukungcola okuncane ku-compressor, umjikelezo wokuthola nokulungisa ungaba mude kakhulu.
Izinkomba zokuqapha eziyinhloko:
1) Inkomba yenani le-PH: ukufakwa kwe-asidi kawoyela wokugcoba kuzothinta ngqo impilo yenjini ye-compressor, ngakho-ke i-asidi kawoyela wokugcoba kufanele ihlolwe njalo ukuze kubonakale ukuthi iyafaneleka yini. I-asidi evamile yokugcoba engaphansi kwe-PH6 iyadingeka ukuze kufakwe enye esikhundleni sayo. Uma i-asidi ingenakuhlolwa, umshini wokomisa isihlungi sesistimu kufanele ushintshwe njalo ukuze kugcinwe ukoma kwesistimu kusesimweni esijwayelekile.
2) Inkomba yokungcola: Uma ukungcola okuku-100ml kawoyela wokuqandisa kudlula u-5mg, kunconywa ukuthi kufakwe okunye esikhundleni sawoyela wokuqandisa.
3) Okuqukethwe kwamanzi: Uma kudlula i-100ppm, kuyadingeka ukufaka esikhundleni samafutha okuqandisa.
Umjikelezo wokufaka esikhundleni:
Ngokuvamile njalo emahoreni ayi-10,000 okusebenza kufanele kuhlolwe noma kushintshwe i-lubricant, futhi ngemva kokusebenza kokuqala, kunconywa amahora angu-2500 ukuze kushintshwe i-lubricant futhi kuhlanzwe isihlungi samafutha. Ngoba izinsalela ze-system assembly zizoqongelelwa ku-compressor ngemva kokusebenza okusemthethweni. Ngakho-ke, i-lubricating oil kufanele ishintshwe kanye emahoreni angu-2500 (noma izinyanga ezi-3), bese kuthi njalo ngokwe-system cleanness, uma i-system cleanness ilungile, ingashintshwa kanye emahoreni ayi-10000 (noma ngonyaka).
Uma izinga lokushisa lokukhipha i-compressor ligcinwa isikhathi eside esimweni sokushisa okuphezulu, khona-ke ukuwohloka kwe-lubricant kuqhubeka ngokushesha, kumele kuhlolwe njalo (njalo ezinyangeni ezi-2) izici zamakhemikhali ze-lubricant, zehlulekile ukushintshwa. Uma ungakwazi ukuhlola njalo, ungalandela ithebula lesiphakamiso elilandelayo.
Okwesithathu, indlela yokusebenza yokufaka esikhundleni samafutha esiqandisini:
1) Ukufakwa esikhundleni samafutha esiqandisini ngaphandle kokuhlanza kwangaphakathi:
I-compressor yenza isenzo sokupompa ukuze ibuyisele i-refrigerant yesistimu ohlangothini lwe-condenser (qaphela ukuthi ingcindezi encane yokumunca yesenzo sokupompa ingaphansi kuka-0.5Kg/cm2G), susa i-refrigerant ku-compressor, ugcine ingcindezi yangaphakathi njengomthombo wamandla, bese ukhipha uwoyela we-refrigerant ku-valve ye-angle yokukhipha uwoyela ye-compressor.
2) Shintsha uwoyela wefriji bese uhlanza ingaphakathi:
Khipha amandla kawoyela njengoba kuchaziwe ngenhla, ngemva kokuba uwoyela oqandisiwe usususiwe futhi ingcindezi ngaphakathi nangaphandle kwe-compressor ilinganisiwe, sebenzisa isikrufu esinama-hexagonal ukuze ukhulule amabhawodi e-flange, susa isixhumi sesihlungi sikawoyela bese usula i-flange yembobo (noma i-flange ye-switch level kawoyela), susa ukungcola ethangini likawoyela le-compressor, bese uhlola ukuthi i-mesh yembobo yesihlungi sikawoyela iphukile yini, bese uqhumisa udoti kanye nokungcola okukuwo, noma shintsha isihlungi sikawoyela ngentsha, qaphela ukuthi Uma ushintsha i-nut yesihlungi esisha kufanele iboshwe ngokuqinile futhi ivalwe kahle ukuze kuvinjelwe ukuvuza kwangaphakathi; i-liner engaphakathi kwejoyinti lesihlungi sikawoyela kumele ishintshwe ngentsha ukuze kuvinjelwe ukuvuza kwangaphakathi; enye i-liner ye-flange nayo iyanconywa ukuthi ibuyekezwe.
Amanothi angu-IV:
1. Izinhlobo ezahlukene zamafutha okuqandisa akumelwe zixutshwe, ikakhulukazi uwoyela wamaminerali kanye namafutha e-ester okwenziwa akumelwe axutshwe.
2. Uma ushintsha amazinga ahlukene kawoyela wokuqandisa, qaphela uwoyela wokuqandisa wokuqala osele ohlelweni okufanele ukhishwe.
3. Amanye amafutha anombala ofana nowe-hygroscopic, ngakho-ke ungawavezi uwoyela emoyeni isikhathi eside. Nciphisa isikhathi sokuchayeka ngangokunokwenzeka futhi uphume ngangokunokwenzeka ngesikhathi sokufakwa.
4. Uma uhlelo lunenkinga yokusha kwenjini ye-compressor, qaphela kakhulu ukususa i-asidi esele ohlelweni lapho ushintsha umshini omusha, futhi uhlole ubumuncu bamafutha okupholisa ngemva kwamahora angamashumi ayisikhombisa nambili okusebenza, kunconywa ukuthi kushintshwe uwoyela obandayo kanye nomshini wokomisa izihlungi ukuze kuncishiswe amathuba okugqwala kwe-asidi. Ngemva kwalokho, hlola noma ushintshe uwoyela obandayo futhi ngemva kwenyanga eyodwa yokusebenza.
5. Uma uhlelo lube nengozi yokungena kwamanzi, naka ngokukhethekile ukususa amanzi ngendlela ehlanzekile, futhi ngaphezu kokushintsha uwoyela wokuqandisa, naka ngokukhethekile ukuthola ubumuncu bamafutha bese ushintsha uwoyela omusha kanye nokomisa isihlungi ngesikhathi.
