Cov hauv qab no piav qhia txog ASTM / ISO viscosity qib ntawm cov kabmob muaj roj lubricants. Daim duab 13. Cov qib viscosity ntawm cov khoom siv roj nplua nyeem. ISO Viscosity System Conventional Antirust thiab Antioxidant Lubricants Pas Antirust thiab Antioxidant (R&O) lubricants yog cov khoom siv roj ntau tshaj plaws. Cov lubricants no tuaj yeem siv rau Timken® bearings siv ntau yam kev lag luam yam tsis muaj qhov tshwj xeeb. Table 24. Cov yam ntxwv yam ntxwv ntawm kev pom zoo cov pa R&O lubricants Base raw cov ntaub ntawv Refined siab viscosity index petroleum additives Anti-corrosion thiab antioxidant viscosity Performance index Min. 80 hli Max. -10 ° C Viscosity qib ISO/ASTM 32 txog 220 Qee qhov qis qis thiab/lossis siab dua ambient kub daim ntawv thov yuav tsum muaj qib viscosity siab dua. Kev kub ceev thiab/lossis kub tsis tshua muaj daim ntawv thov yuav tsum tau qis viscosity qib.
Extreme Pressure (EP) Industrial Iav Roj Hmab siab iav roj tuaj yeem lubricate Timken® bearings hauv cov khoom siv hnyav feem ntau. Lawv tuaj yeem tiv taus qhov cuam tshuam txawv txav uas muaj nyob rau hauv cov khoom siv hnyav. Table 25. Pom zoo muaj EP iav roj yam ntxwv. Basic raw khoom. Refined siab viscosity index roj av additives. Anti-corrosion thiab antioxidants. Siab siab (EP) additives (1)-load chav kawm 15.8 kg. Viscosity index min. 80 hli max. -10 ° C viscosity qib ISO/ASTM 100, 150, 220, 320, 4601) ASTM D 2782 Industrial Extreme Pressure (EP) iav roj yog tsim los ntawm cov roj av zoo heev ntxiv rau cov khoom siv inhibitor ntxiv. Lawv yuav tsum tsis txhob muaj cov ntaub ntawv uas tuaj yeem corrode lossis abrade cov bearings. Inhibitors yuav tsum muab kev tiv thaiv oxidation ntev ntev thiab tiv thaiv bearings los ntawm corrosion nyob rau hauv lub xub ntiag ntawm noo noo. Cov roj lubricating yuav tsum muaj peev xwm zam kom tsis txhob foaming thaum siv thiab muaj cov khoom tsis zoo. Cov additives siab heev kuj tuaj yeem tiv thaiv khawb nyob rau hauv ciam teb lubrication tej yam kev mob. Qhov pom zoo viscosity qib ntau yog dav heev. Cov ntawv thov kub thiab / lossis qis qis feem ntau xav tau cov qib viscosity siab dua. Tsawg kub thiab / lossis kev siv ceev ceev yuav tsum tau qis dua qib viscosity.
