Umthelela we-Viscosity ye-Lubricating Oil ekusebenzeni kwe-Refrigeration Compressors kanye ne-Data-Driven Analysis

Ipharamitha yokunamathela kawoyela yokunisela ithinta ngqo ukuzinza kokusebenza, ukusebenza kahle kokupholisa, kanye nesikhathi sokuphila kwemishini yokupholisa. Kokubili ukunamathela okuphakeme kakhulu nokuphansi kungaholela ezinkingeni ezithile, futhi imithetho yokuthonya ingavezwa kahle uma kubhekwa idatha ejwayelekile yokusebenza kwezokukhiqiza:

Uma i-viscosity ye-oli yokunisela iphakeme kakhulu (isb. idlula umkhawulo ophezulu we-viscosity grade edingekayo kwemishini ngama-20% noma ngaphezulu), izokwandisa ukumelana kwamanzi ngaphakathi kwe-compressor futhi ikhulise ukusetshenziswa kwamandla okuphikisana kwemishini ngama-15%-30%, ngaleyo ndlela ibangele ukukhuphuka okukhulu kokushisa kokukhishwa. Ngokuvamile, ngokukhuphuka okungu-10% ngaphezu kwe-viscosity ejwayelekile, ukushisa kokukhishwa kungakhuphuka ngama-5-8℃. Ukushisa kokukhishwa okuphezulu kakhulu kuphazamisa ibhalansi yokushintshana kokushisa komjikelezo wokupholisa, kuholele ekwehleni okungu-8%-12% kwe-coefficient of performance (COP) nokuncipha okubonakalayo kokusebenza kokupholisa. Kungase futhi kusheshise ukuhlala isikhathi eside nokonakala kwe-oli yokunisela, kunciphise impilo yayo yokusebenza ngaphezu kuka-30%.

Uma i-viscosity ye-oli yokuhlanza iphansi kakhulu (ngaphansi komkhawulo ophansi we-viscosity edingekayo kwemishini ngama-15% noma ngaphezulu), ngeke ikwazi ukuveza ifilimu ye-oli esebenzayo phezu kobuso bezingxenye ezihambayo ze-compressor (ubukhulu befilimu ye-oli obufanele kufanele bube phakathi kuka-5-10μm, kanti i-viscosity ephansi kakhulu inganciphisa ubukhulu befilimu ye-oli bube ngaphansi kuka-2μm). Nakuba lokhu kungaholeli ngqo ekwandeni kokushisa kokukhishwa (idatha eyalinganisiwe ikhombisa ukuthi ukwehla kokushisa kokukhishwa akudluli ±2℃ uma i-viscosity iphansi kakhulu), kuzoholela ekunganeliseki kokuhlanza. Lokhu kuholela ekwandeni kwe-coefficient yokuhlakazeka kwezinto ezibalulekile ezifana ne-piston ye-compressor kanye nezindawo zokugijima, kanye nokwanda kwe-40%-60% kwenani lokugqoka. Ezimweni ezinzima, kungaholela ezinkingeni ezifana nokubanjwa kwezinto kanye nokuvuza, kunciphisa isikhathi sokugcinwa kwe-compressor ngama-50% futhi kukhuphule kakhulu izindleko zokusebenza nokugcinwa.

Ngakho-ke, izinhlelo zokupholisa kumele ziqinise ukulawula ubunzima bama-oli okuthambisa ngaphakathi komkhawulo okukhulunywe ngawo ngempahla (isb., izinga elivamile le-ISO VG 32 kanye ne-VG 46). Kuhlale kunconywa ukuthi ukwephula phakathi kobunzima bokusebenza bempela kanye nenani elijwayelekile akudluli ±10%, ukuze kuhlangabezane nokusebenza kahle kokupholisa kanye nokuvikelwa kokuthambisa kwemishini.
