Data on operational temperatures represent values which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mehaniko-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.
Oil MS-14 is oil of selective clearing. Apply in axial hinges of plugs of screws of helicopters and as base to some engine oils and greasings.
The unified oil on an oil basis with a complex of additives. It is developed in exchange oilmix, oils MN-7,5 and a VNIINP-7. It is possible to apply in turbo-propeller engines of all types at oil temperature on an exit from the engine to 150 °С.
This oil produced is from sulfurous petroleums. Contains a special composition of additives. It is intended for greasing of engines and a compressor part gas engine compressor types 8GK, 8GKM, 10GKM, 10GKN and the units similar to them working on natural gas. This oil is applicable in circulating lubricant systems gas-engine-compressor unit.
Synthetic on the basis of organosilicon liquids with an additive. It is characterized maximum (in comparison with other oils) thermo oxidizing stability, low volatility, good low-temperature properties. It is possible to use in gas-turbine engines with oil temperature on an exit from the engine to 250-280 °С.
