Hydraulic liquid of a GZHD-14s is a mix deeprefined residual and distillate components from sulphurous petroleums. For improvement of operational properties into oil enter antioxidizing, anticorrosive and antifoamy additives. Apply in the basic hydraulic systems of screws of an adjustable step of courts.

(TU 38.1011282-89)
Hydraulic oil of the sort «A» is prepared from deeprefined and dearomatized oil basis with viscous, antioxidizing, anticorrosive, antiwear, depressor and antifoamy additives.
Oil of sort «A» is applied to hydrotransformers and automatic transmissions of cars and other mobile technics; hydrosystems ship closings of hatchways, hydraulic cranes and steering machines

Composition: represents a mix of distillate and residual components with addition of depressant, antifoam and multicomponent (improving antioxidizing, anticorrosive and dispersing characteristics) additives. Possesses high enough level of wear-protective properties.

Applications: the oil is used is in hydraulic systems of the hinged equipment and a steering of tractors, self-propelled agricultural cars and dumping cars. Earlier not enough such structure was produced in accordance with GOST 10541-78 under mark of engine oil ?-8? for the engines carburetor.

Oil MGE-10? (GOST 38 01281-82) — the dearomatized low cold-test fraction received from hydrocracking products of a mix paraffinic petroleums. Contains thickening, antioxidizing, anticorrosive and wear-protective additives.
This oil is intended for operating in a range of temperatures from — (60-65) °C to + (70-75) °C.

Color: light brown, transparent
Density at 20°?, kg/ cu.m, not more than: 860
Kinematic viscosity, cSt, at 50 °C, not less than: 10
Kinematic viscosity, cSt, at 40 °C, not less than: —
Kinematic viscosity, cSt, at -50 °C, not less than: 1500
Acid number, mg, not more than: 0
Flash temperature, in an open cup, °C, not lower than: 96

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 mechanical-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.

Working liquid NGZH-4u is synthetic flame safety a liquid on the basis of aethers of phosphoric acid. It has been created liquid NGZH-4 in exchange earlier widely applied in aircraft calling erosion of valves of hydrosystems and, as consequence of it, liquid leak. Liquid NGZH-4u is erosion-resistant liquid, contains the additives improving it ??????????, antierosive, antioxidizing properties. It is efficient in the range of temperatures from -55 to 125 °C at working pressure to 21 megapascal. Has temperature of spontaneous ignition 650-670 °?, slowly burns in a flame, but does not sustain combustion and does not extend a flame unlike oil liquids of type ???-10. Is good softener and solvent for many nonmetallic materials, therefore at use of the last in contact to liquid NGZH-4u it is necessary to check carefully their compatibility or to use only those materials which are picked specially up and recommended for liquids of type NGZH.
