    Mga Oil

    On the Russian territory should be used hydraulic oil specifically designed for fluid power drives and serially produced by domestic refineries: MG-15B gost 17479.3-85 (VMGZ tu 38.101479-00) and Mga-46V (MG-30 tu 38.001347-83), which according to gost 26191-84 "oils. Lubricants and special liquids (restrictive list and order of appointment), Annex 8 to gost 14892-69 "Hydrostatic drive for articles in the" northern "performance" and ost 22-1488-86 are the main varieties of fluids. Hydraulic oil MG-15B (VMGZ tu 38.101479-00) multigrade hydraulic thickened intended for use by mobile machinery and industrial equipment in areas with cold Climate (CL), preferably with an axial-piston pumps and motors, and seasonal – in winter with a gear-and vane pump. This oil is produced on the basis of thickened with a composition of additives, provide the necessary viscosity, low temperature and foaming properties. It provides start-up to the work of the hydraulic drive, without pre-heating and year-round operation of machinery and hydraulically equipment without the seasonal change in the temperature range from -53 to +53 C. Hydraulic oil Mga-46V (MG-30 tu 38.001347-83) is designed for operation of mobile hydraulic machinery and industrial equipment in the open air temperate areas (V) as a summer class and in all seasons for areas with warm climates (T) in the range of temperatures from -20 to +75 C. Its oil is produced from selective treatment with the addition of antioxidant, antifoam additives and depressatora, which lowers the freezing temperature.

    The oil has good lubricating properties, resistance to oxidation and deposition of tar deposits, and also against foaming satisfactorily protects metal surfaces from corrosion. Frequency of replacement of the main varieties of hydraulic oils – in 3500 4000 h, but at least once in 2 years. In the absence of major varieties hydraulic oil is allowed to seasonal change: in the winter – MG-22A (AC) in the summer – I-30A. Before the first start of the pump in the work necessary to complete all components of the hydraulic system – pumps, hydraulic cylinders, filters, heat exchangers – the fluid, while ensuring that production of air through the tube or fitting drain pipes until the outer leak.
