Amanothi Abalulekile Ngokukhetha Amafutha Esiqandisi Wama-compressor Wesiqandisi Wemiqondile

Uma ukhetha uwoyela wokuqandisa ama-compressor wokuqandisa we-reciprocating piston, uhlobo lwe-refrigerant kufanele lube yisisekelo esiyinhloko sokufanisa uhlobo lukawoyela. Nge-R22 refrigeration systems, uwoyela wokuqandisa we-mineral 3GS noma i-4GS uyatuswa. Kodwa-ke, ngezinhlelo ze-refrigerant ezihambisana nemvelo njenge-R134a, i-R404A, i-R407C, ne-R410A, uwoyela we-synthetic we-POE kufanele usetshenziswe; ukuxuba uwoyela we-mineral nowoyela we-synthetic akuvunyelwe nhlobo ukuze kugwenywe ukuhlukana kukawowiela nokuhluleka kokugcoba. Izinga le-viscosity kufanele likhethwe ngokunengqiqo ngokuya ngezimo zokusebenza. Izinga le-viscosity le-VG32 ne-VG46 lifanele izimo ezijwayelekile zokusebenza. Ama-oyela anezinga eliphansi le-pour point kufanele akhethwe kumayunithi asebenza ezingeni lokushisa eliphansi ukuze kugwenywe ukubunjwa kwe-wax nokuncipha kokugeleza ezingeni lokushisa eliphansi, kanti ama-oyela anezinga eliphezulu le-viscosity ayadingeka ezimweni zokushisa okuphezulu ukuze kuqinisekiswe ukuzinza kwe-oil film. Ukulawulwa okuqinile kwezinkomba ze-physicochemical zikawoyela nakho kuyadingeka, nezidingo zokuthi inani le-acid lingeqi ku-0.04 mgKOH/g, i-pour point ingeqi ku- -50°C, futhi i-flash point ihlangabezana namazinga, ukuze kugwenywe ukubola kwezingxenye nokubunjwa kwe-carbon ezingeni lokushisa eliphezulu. Ngenxa yokunyakaza okuphindaphindayo okushukumiswa umshini wokuxhumanisa i-crankshaft ku-reciprocating compressors, izakhiwo zokugcoba nokubopha zikawoyela wokuqandisa zidinga kakhulu. Uwoyela kufanele uhlangabezane nezidingo zokugcoba nokubopha zamapheya okungqubuzana njengamaringi e-piston, izindonga zesilinda, amapuleti evidijithali, namabheringi, ngaleyo ndlela kunciphise ukuguga komshini nokuvuza kwangaphakathi. Ezicini zokusebenza, izincazelo zokukhetha zomenzi wemishini yasekuqaleni kufanele zilandelwe, ngokukhetha ama-oyela wokuqandisa akhethekile omkhiqizo. Ukuhlolwa kwekhwalithi kawoyela njalo nokushintshwa ngesikhathi ngokuhambisana namahora okusebenza kufanele kwenziwe ukuze kuqinisekiswe ukusebenza okuzinzile nokuthembekile kwe-compressor isikhathi eside.
