Iicompressors ziyinxalenye ebalulekileyo phantse yonke indawo yokuvelisa. Ngokuqhelekileyo zibizwa ngokuba yintliziyo yayo nayiphi na inkqubo yomoya okanye igesi, ezi mpahla zifuna ingqalelo ekhethekileyo, ngakumbi ukuthambisa kwazo. Ukuze uqonde indima ebalulekileyo i-lubrication edlala kwiicompressors, kufuneka uqale uqonde umsebenzi wabo kunye nemiphumo yenkqubo kwi-lubricant, apho i-lubricant inokukhetha kwaye yintoni uvavanyo lohlalutyo lweoli ekufuneka lwenziwe.
● Iintlobo zeCompressor kunye neMisebenzi
Uninzi lweentlobo ezahlukeneyo zecompressor ziyafumaneka, kodwa indima yazo ephambili iphantse ifane. Iicompressors zenzelwe ukuqinisa uxinzelelo lwegesi ngokunciphisa umthamo wayo wonke. Ngamagama alula, umntu unokucinga ngecompressor njengepompo efana negesi. Ukusebenza ngokusisiseko kuyafana, umahluko omkhulu kukuba icompressor inciphisa umthamo kwaye ihambisa igesi ngenkqubo, ngelixa impompo icinezela kwaye ithutha ulwelo ngenkqubo.
Iicompressors zinokwahlulwa zibe ziindidi ezimbini jikelele: ukufuduswa okulungileyo kunye nokuguquguqukayo. I-Rotary, diaphragm kunye ne-reciprocating compressors ziwela phantsi kokuhlelwa kwe-positive-displacement. Iicompressor ezijikelezayo zisebenza ngokunyanzelisa iigesi kwiindawo ezincinci ngokusebenzisa izikrufu, iilobes okanye i-vanes, ngelixa i-diaphragm compressors isebenza ngokucinezela igesi ngokuhamba kwenwebu. Iicompressor eziphindaphindayo zicinezela igesi ngepiston okanye uthotho lweepistons eziqhutywa yicrankshaft.
I-Centrifugal, i-mix-flow kunye ne-axial compressors ikudidi oluguquguqukayo. Icompressor ye-centrifugal isebenza ngokucinezela igesi usebenzisa idiski ejikelezayo kwindlu eyenziweyo. Icompressor exutyiweyo isebenza ngokufana ne-centrifugal compressor kodwa iidrives zihamba nge-axially kune-radially. Iicompressor zeAxial zenza ucinezelo ngothotho lweefoyile zomoya.
● Iimpembelelo kwii-Lubricants
Phambi kokukhethwa kwe-lubricant yecompressor, enye yezona zinto ziphambili ekufuneka ziqwalaselwe luhlobo loxinzelelo lwe-lubricant enokuthi lube phantsi kwalo ngelixa ukwinkonzo. Ngokuqhelekileyo, i-lubricant stressors kwi-compressors ibandakanya ukufuma, ubushushu obugqithisileyo, igesi ecinezelweyo kunye nomoya, amasuntswana esinyithi, ukunyibilika kwegesi, kunye neendawo ezishushu zokukhupha.
Gcina ukhumbule ukuba xa igesi ixinzelelwe, inokuba nemiphumo emibi kwi-lubricant kwaye ibangele ukuhla okubonakalayo kwi-viscosity kunye ne-evaporation, i-oxidation, i-carbon deposit kunye ne-condensation ekuqokeleleni komswakama.
Nje ukuba uyazi iinkxalabo eziphambili ezinokuziswa kwi-lubricant, ungasebenzisa olu lwazi ukunciphisa ukhetho lwakho lwe-lubricant yecompressor efanelekileyo. Iimpawu ze-lubricant eyomeleleyo yomgqatswa ziya kubandakanya uzinzo oluhle lwe-oxidation, i-anti-wear kunye ne-corrosion inhibitor additives, kunye neempawu zokuchithwa. Izitokhwe ezisisiseko zokwenziwa zisenokwenza ngcono kumanqanaba obushushu abanzi.
● UkuKhetha iLubricant
Ukuqinisekisa ukuba une-lubricant efanelekileyo kuya kubaluleka kwimpilo yecompressor. Inyathelo lokuqala kukubhekisa iingcebiso kumenzi wesixhobo sokuqala (OEM). I-compressor lubricant viscosities kunye namalungu angaphakathi athatywayo anokwahluka kakhulu ngokusekelwe kuhlobo lwecompressor. Iingcebiso zomenzi zinokubonelela ngesiqalo esihle.
Okulandelayo, qwalasela igesi ecinezelweyo, njengoko inokuchaphazela kakhulu i-lubricant. Uxinzelelo lomoya lunokukhokelela kwimiba ngamaqondo obushushu e-lubricant aphakamileyo. Iigesi zeHydrocarbon zivame ukunyibilikisa izithambiso kwaye, ngokulandelayo, zithobe kancinci i-viscosity.
Iigesi ezingasebenzi ngokwekhemikhali ezifana nekharbon diokside kunye ne-ammonia zinokusabela kunye ne-lubricant kwaye zehlise i-viscosity kunye nokwenza iisepha kwinkqubo. Iigesi ezisebenza ngokwekhemikhali ezifana neoksijini, iklorini, i-sulphur dioxide kunye nehydrogen sulfide zinokwenza iidipozithi eziyi-tacky okanye zibe nomhlwa kakhulu xa kukho ukufuma okuninzi kwi-lubricant.
Kufuneka kwakhona uthathele ingqalelo indawo apho icompressor lubricant iphantsi kwayo. Oku kunokubandakanya ubushushu obuphakathi, ubushushu bokusebenza, ungcoliseko olujikelezileyo lwemoya, nokuba icompressor ingaphakathi kwaye igqunyiwe okanye ingaphandle kwaye ibonakaliswe kwimozulu embi, kunye neshishini esetyenziswa kulo.
Iicompressors zihlala zisebenzisa izithambisi zokwenziwa ngokusekelwe kwingcebiso ye-OEM. Abavelisi bezixhobo bahlala befuna ukusetyenziswa kwezithambisi zabo ezinophawu njengemeko yewaranti. Kwezi meko, unokufuna ukulinda de kube semva kokuba ixesha lewaranti liphelile ukwenza utshintsho lwe-lubricant.
Ukuba isicelo sakho ngoku sisebenzisa isithambisi esekwe kwiminerali, ukutshintshela kwi-synthetic kufuneka kuthetheleleka, njengoko oku kuya kuba kubiza kakhulu. Ewe kunjalo, ukuba iingxelo zakho zohlalutyo lweoyile zibonisa iinkxalabo ezithile, i-lubricant yokwenziwa inokuba lukhetho oluhle. Nangona kunjalo, qiniseka ukuba awujonganga nje iimpawu zengxaki kodwa kunokusombulula oonobangela benkqubo.
Zeziphi izithambiso zokwenziwa ezenza eyona ngqiqo kwicompressor application? Ngokuqhelekileyo, i-polyalkylene glycols (PAGs), i-polyalphaolefins (POAs), ezinye i-diesters kunye ne-polyolesters zisetyenziswa. Yeyiphi kwezi zokwenziwa ukukhetha kuya kuxhomekeka kwi-lubricant otshintshayo kuyo kunye nesicelo.
Ibandakanya ukumelana ne-oxidation kunye nobomi obude, i-polyalphaolefins ngokubanzi iyindawo efanelekileyo yee-oyile zeminerali. I-polyalkylene glycols enganyibilikiyo ngamanzi inika ukunyibilika okulungileyo ukunceda ukugcina iicompressors zicocekile. Ezinye ii-esters zinokunyibilika okungcono kune-PAGs kodwa zinokuzabalaza nokufuma okugqithisileyo kwinkqubo.

Umzekelo wee-slates zokuvavanya uhlalutyo lweoli kunye nemida ye-alamu ye-compressor ye-centrifugal.
● Iimvavanyo zoHlalutyo lweoyile
Uvavanyo oluninzi lunokwenziwa kwisampulu yeoli, ngoko ke kuyafuneka ukuba ubaluleke kakhulu xa ukhetha olu mvavanyo kunye nesampulu yamaxesha. Uvavanyo kufuneka lubandakanye amacandelo amathathu aphambili ohlalutyo lwe-oyile: iimpawu zolwelo lwesithambiso, ubukho bongcoliseko kwinkqubo yokuthambisa kunye nayo nayiphi na inkunkuma enxitywayo evela kumatshini.
Ngokuxhomekeke kuhlobo lwecompressor, kunokubakho uhlengahlengiso oluncinci kwisileyiti sovavanyo, kodwa ngokuqhelekileyo kuqhelekile ukubona i-viscosity, uhlalutyo lwe-elemental, i-Fourier transform infrared (FTIR) spectroscopy, inombolo ye-asidi, amandla evarnish, uvavanyo lwe-oxidation yesitya esijikelezayo (RPVOT). ) kunye novavanyo lokucinywa okucetyiswayo kuvavanyo lweempawu zolwelo lwe-lubricant.
Uvavanyo longcoliseko lolwelo lwecompressor olunokuthi lubandakanye inkangeleko, i-FTIR kunye nohlalutyo olusisiseko, ngelixa ekuphela kovavanyo lwesiqhelo ukusuka kwindawo yokunxiba yobutyobo iya kuba luhlalutyo olusisiseko. Umzekelo wee-slates zokuvavanya uhlalutyo lweoli kunye nemida ye-alamu ye-compressor ye-centrifugal iboniswe ngasentla.
Kuba iimvavanyo ezithile zinokuvavanya iinkxalabo ezininzi, ezinye ziya kuvela kwiindidi ezahlukeneyo. Umzekelo, uhlalutyo olusisiseko lunokuthi lubambe amazinga okuncipha okongeziweyo ngokwembono yepropathi yolwelo, ngelixa amaqhekeza amacandelo avela kuhlalutyo lwenkunkuma okanye i-FTIR inokuchonga i-oxidation okanye ukufuma njengesingcolisi solwelo.
Imida ye-alam kaninzi ibekwa njengokusilela kwilabhoratri, kwaye uninzi lwezityalo aluthandabuzi ukufaneleka kwazo. Kuya kufuneka uphonononge kwaye uqinisekise ukuba le mida ichaziwe ukuze ihambelane neenjongo zakho zokuthembeka. Njengoko uphuhlisa inkqubo yakho, unokufuna ukucinga ngokutshintsha imida. Rhoqo, imida ye-alam iqala phezulu kwaye itshintsha ngokuhamba kwexesha ngenxa yeethagethi zococeko ezinobundlobongela, ukuhluzwa kunye nolawulo lokungcoliseka.
● Ukuqonda iCompressor Lubrication
Ngokumalunga nokuthambisa kwazo, iicompressors zinokubonakala zintsonkothile. Okukhona wena kunye neqela lakho niwuqonda ngcono umsebenzi wecompressor, iziphumo zenkqubo kwi-lubricant, yeyiphi i-lubricant ekufuneka ikhethwe kwaye zeziphi iimvavanyo zohlalutyo lweoyile ekufuneka zenziwe, angcono amathuba akho okugcina kunye nokuphucula impilo yezixhobo zakho.
