Description
Industrial Oil

petroleum oils used in industry and homes for the lubrication of machinery (machines, instruments, and so on). Baku, Emba, and eastern types of crude oil are used in their production. Industrial oils sometimes contain vegetable oils (for example, castor, mustard, or rapeseed) as additives, as well as antioxidizing, thickening, and anticorrosive dopes for improving their service qualities. The range of industrial oils is constantly being varied and supplemented with new brands, particularly synthetic oils (for example, silicon, polyester, and fluorohydrocarbon).
Industrial oils are subdivided according to viscosity into light, medium, and heavy types. Light oils, with viscosity of 5–10 centistokes (1 centistoke = 10−6 m2/sec) at 50°C and pour points as low as –25°C, are used for lubricating high-speed, low-load machinery. This group includes L (velosite) oil and T (petrolatum) oil, which are used for lubrication of spinning and doubling frames in the textile industry, for spindles of metal-working lathes and low-power high-speed motors; separator oil L, for lubrication of light-duty separators; sewing oil for sewing, binding, and knitting machines; and instrument oil MVP (pour point –60°C), for lubricating monitoring and measuring instrumentation. Medium industrial oils, with viscosity of 10–50 centistokes at 50°C and pour points as low as— 30°C, are used to lubricate machinery operating at medium speeds and under medium loads.
