Okokuqala, indima yamafutha okugcoba:
1) Kwakhiwa uphawu oluguquguqukayo phakathi kwesikulufu, igumbi lokucindezela kanye nezikulufu zesilisa nezesifazane ukunciphisa ukuvuza kwesiqandisi kusuka ohlangothini lokucindezela okuphezulu kuya ohlangothini lokucindezela okuphansi ngesikhathi senqubo yokucindezela.
2) Ukuze kuphole i-refrigerant ecindezelwe, uwoyela ufakwa kwi-compressor ukuze umunce ukushisa okukhiqizwa yigesi ye-refrigerant ngesikhathi senqubo yokucindezela futhi kuncishiswe izinga lokushisa lokukhipha umoya.
3) Kwakhiwa ifilimu kawoyela phakathi kwe-bearing kanye nesikulufu ukuze kusekelwe i-rotor futhi kuyithambise.
4) Idlulisa amandla okucindezela okuhlukile, ishayela uhlelo lokulungisa umthamo, futhi ilungisa indawo yesilayida sokulungisa umthamo ngesenzo se-valve ye-solenoid yokulayisha nokukhipha i-compressor ukuze ikwazi ukulawula ukulungiswa kwamandla kwe-compressor.
5) Nciphisa umsindo wokugijima
bonisa:
Uwoyela wokugcoba ngaphakathi kwe-compressor uyisihluthulelo sokugcina ukusebenza okuvamile kwe-compressor. Izinkinga ezijwayelekile zamafutha okugcoba yilezi:
1) Izinto zangaphandle ziyaxutshwa, okubangela ukungcola kwamafutha okugcoba futhi kuvimbele isihlungi samafutha.
2) Umphumela wokushisa okuphezulu ubangela ukuwohloka kwamafutha okugcoba kanye nokulahlekelwa umsebenzi wokugcoba.
3) Ukungcoliswa kwamanzi, ukwakheka kwe-asidi kanye nokuguguleka kwenjini ohlelweni.
2. Ukuhlolwa nokushintshwa kwamafutha okuqandisa i-compressor:
Kwabakhiqizi bezinhlelo, umjikelezo wokuthola nokufaka esikhundleni uwoyela wokuqandisa we-compressor uhlobene nokulawulwa kwenqubo yokukhiqiza kwawo. Uma ukuhlanzeka kwe-evaporator yesistimu, i-condenser kanye nepayipi lesistimu kulawulwa kahle, ukungcola okungena kwi-compressor kuzoba kuncane kakhulu, futhi isikhathi sokuhlola nokulungisa singandiswa ngokulinganisela.
Izinkomba zokuqapha eziyinhloko:
1) Inkomba yenani le-PH: Ukufakwa kwe-asidi ku-oyela wokugcoba kuzothinta ngqo impilo yenjini ye-compressor, ngakho-ke kuyadingeka ukuhlola njalo ukuthi i-asidi ya-oyela wokugcoba iyafaneleka yini. Ngokuvamile, i-asidi ya-oyela wokugcoba ingaphansi kwe-PH6 futhi idinga ukushintshwa. Uma i-asidi ingenakuhlolwa, umshini wokomisa isihlungi sesistimu kufanele ushintshwa njalo ukuze kugcinwe ukoma kwesistimu kusesimweni esijwayelekile.
2) Inkomba yezinga lokungcola: Uma ukungcola okuku-100ml kawoyela wokuqandisa kudlula u-5mg, kunconywa ukuthi kufakwe omunye uwoyela wokuqandisa esikhundleni sawo.
3) Okuqukethwe kwamanzi: ngaphezu kwe-100ppm, uwoyela wokuqandisa udinga ukushintshwa.
Ukushintsha umjikelezo:
Ngokuvamile, uwoyela wokugcoba kumele uhlolwe noma ushintshwe njalo emahoreni ayi-10,000 okusebenza, futhi ngemva kokuhlinzwa kokuqala, kunconywa ukuthi kushintshwe uwoyela wokugcoba bese kuhlanzwa isihlungi samafutha njalo emahoreni angu-2,500. Izinsalela ezibangelwa ukuhlanganiswa kwesistimu zizoqongelela ku-compressor ngemva kokusebenza kwangempela. Ngakho-ke, uwoyela wokugcoba kufanele ushintshwe njalo emahoreni angu-2,500 (noma izinyanga ezi-3), bese kuthi ngezikhathi ezithile kuye ngokuhlanzeka kwesistimu. Uma ukuhlanzeka kwesistimu kukuhle, kungashintshwa njalo emahoreni ayi-10,000 (noma njalo ngonyaka).
Uma izinga lokushisa lokukhipha umoya le-compressor ligcinwa lisezingeni lokushisa eliphezulu isikhathi eside, ukuwohloka kwamafutha okugcoba kuzoqhubeka ngokushesha, futhi izici zamakhemikhali zamafutha okugcoba kumele zihlolwe njalo (njalo ezinyangeni ezi-2), futhi zishintshwe uma zingafaneleki. Uma ukuhlolwa okuvamile kungenzeki, kungenziwa ngokwethebula lezincomo elilandelayo.
3. Indlela yokusebenza yokushintsha uwoyela oqandisiwe:
1) Ukufaka esikhundleni samafutha okupholisa ngaphandle kokuhlanza kwangaphakathi:
I-compressor yenza isenzo sokupompa ukuze ibuyisele i-refrigerant yesistimu ohlangothini lwe-condenser (qaphela ukuthi ingcindezi encane yokumunca yesenzo sokupompa ayingaphansi kuka-0.5Kg/cm2G), susa i-refrigerant ku-compressor, ugcine ingcindezi encane yangaphakathi njengomthombo wamandla, bese ubeka i-friji. Uwoyela ukhishwa kusuka ku-valve ye-angle yokukhipha uwoyela ye-compressor.
2) Buyisela uwoyela wokuqandisa bese uhlanza ingaphakathi:
Isenzo sokukhipha uwoyela sinjengoba kuchaziwe ngenhla. Ngemva kokuba uwoyela oqandisiwe usukhishwe uhlanzekile futhi ingcindezi ngaphakathi nangaphandle kwe-compressor isilinganisiwe, khulula amabhawodi e-flange nge-Allen wrench, bese ususa i-joint ye-oil filter kanye ne-flange yembobo yokuvula (noma i-flange ye-oil level switch). Ngemva kokuhlanza, susa ukungcola ethangini likawoyela le-compressor, hlola ukuthi i-mesh ye-oil filter yonakele yini, bese uvuthuza udaka, ukungcola, njll. okukuyo, noma ufake i-oil filter entsha esikhundleni sayo. I-nut ye-interface ye-filter kufanele iqiniswe futhi ivalwe ukuze kuvinjelwe ukuvuza kwangaphakathi; i-gasket yangaphakathi ye-joint ye-oil filter kumele ithathelwe indawo entsha ukuze kuvinjelwe ukuvuza kwangaphakathi; amanye ama-gasket e-flange nawo ayanconywa ukuthi abuyekezwe.
Amanothi amane:
1. Izinhlobo ezahlukene zamafutha okuqandisa akumelwe zixutshwe, ikakhulukazi uwoyela wamaminerali kanye namafutha e-ester okwenziwa akumelwe axutshwe.
2. Uma ushintsha uwoyela wokuqandisa wohlobo oluhlukile, qaphela ukuthi ususa uwoyela wokuqandisa wokuqala osele ohlelweni.
3. Amanye amafutha anezakhiwo ze-hygroscopic, ngakho-ke ungawavezi uwoyela oqandisiwe emoyeni isikhathi eside. Uma ufaka, nciphisa isikhathi sokuvezwa futhi wenze umsebenzi omuhle wokuhlanza nge-vacuum.
4. Uma injini ye-compressor ishile ohlelweni, kufanele kuqashelwe ngokukhethekile ukususa izinto ezisele ze-asidi ohlelweni lapho kufakwa umshini omusha esikhundleni sawo, futhi i-asidi kawoyela wokuqandisa kufanele ihlolwe ngemva kwamahora angu-72 okusebenza nokusebenza kwawo. Kunconywa ukuthi kufakwe esikhundleni sawoyela wokuqandisa kanye nesihlungi sokomisa. , kunciphisa amathuba okugqwala kwe-asidi. Ngemva kokusebenza cishe inyanga, hlola noma faka esikhundleni sawoyela wokuqandisa futhi.
5. Uma kube nengozi yokungena kwamanzi ohlelweni, kufanele kuqashelwe ngokukhethekile ekususweni kwamanzi. Ngaphezu kokushintsha uwoyela wokuqandisa, kufanele kuqashelwe ngokukhethekile ukuthola ubumuncu bawoyela, kanye nokushintsha uwoyela omusha kanye nesihlungi sokomisa ngesikhathi.
