Turbo oil, also known as flat oil or steamer oil, is used mainly for steam turbines in power plants, water tanker generators at hydropower stations and other lubricating events requiring deep lubricants。

Viscosity is determined by three methods: power viscosity, motion viscosity and condition viscosity。
(1) power viscosity: nit is the resistance of the two liquid layers at a distance of 1 cm, each having a relative movement rate of 1 cm/s, in g/rimi-s. 1 g/cm/s = 1 pg: industrially active viscosity units are expressed in berths。
(2) motion viscosity: at temperature t°c, motion viscosity is expressed in sign gamma, in units it is in s, i. E. Square metres per second (m2/s), which is commonly used in physical measurements, and in cst it is in sq. Mm per second (i. E. 1 cst = 1 mm2/s). Motion viscosity is widely used to determine the viscosity of liquid petroleum products such as jet fuel oil, diesel oil, lubricant, post-use lubricant oil, crude oil, etc., which is determined in reverse current method
(3) conditional viscosity: for each country the following three types of condition viscosity are commonly used:
1 ng viscosity is also called engler viscosity. (b) is the ratio of the time (s) required to eject 200 ml samples from a viscosity meter at specified temperatures (e. G. 50 °c, 80 °c, 100 °c) to the time (s) required for distilled water to eject the same volume at 20 °c。
The engine oil 46 is used primarily for the power industry's large steam turbines, for the lubrication and rust resistance of the water tanker generator sets, also for warships and marine vessels with gear-reducing gears, and for other circular lubricating systems that require extreme stability and long-term non-oil replacement, as well as for some air compressors, vacuum pumps, textile machinery, suns and main axes, and all non-extreme pressure gears and bearings。
