Russian market lubricants consistently demonstrates a steady growth trend.Thus a significant proportion of revenue comes from products, focused on the commercial operation in conditions of high temperature extremes and high loads.A worthy place in this segment takes oil VMGZ (off-season hydraulic gelled), provides due to its unique composition of uninterrupted operation of the equipment, equipped with hydraulic drives, in the Far East, Siberia and the Far North.
Scope
earmarking VMGZ - the working environment for hydraulic systems (hydraulic pumps, hydraulic control, hydraulic drives) drilling rigs, lifts, vehicles, agricultural machinery, forestry and construction machinery, industrial machinery.Manufacturers recommend the use of this type of oil in central Russia at low temperatures (assuming VMGZ hydraulic oil used in machinery working in the open air) and northern regions (regardless of the season).
few words about the manufacturers and technology
Among the leading Russian manufacturers of off-season hydraulic oil thickened can name four reputable companies that have a decent business reputation.This "Lukoil", "Gazpromneft", "Shinto", "TNK".
as the basic framework of the future use of the final product quality refined oils with low sulfur content, resulting hydrocracked petroleum fractions or deep dewaxing.For such a framework is characterized by the minimum dynamic viscosity and low pour point.Operational and physical and chemical characteristics, which should be oil VMGZ, provided by the addition of an effective composition of functional additives (anti-corrosion, anti-foaming, anti-wear, anti-oxidant, etc..).

Benefits
Using off-season hydraulic oil is solidified with the operation of specialized machinery and equipment, users are able to:
- protect against corrosion damage and mechanical wear parts of the hydraulic system;
- ensure the smooth operation of the equipment over a wide temperature range (50 ° C to - 40 ° C);
- start producing hydraulic drive, bypassing the stage of pre-heating;
- minimize the need for oil changes (including seasonal) due to high levels of chemical and oxidation stability VMGZ;
- avoided by foaming unnecessary loss of working fluid in the presence of an effective level of cooling and lubrication of the surfaces, which is important for high-speed machinery such as hydraulic systems.
Why is it important quality?
Low-quality oil VMGZ may cause the appearance of a number of problems.Among the most critical main consequences:
- increased contamination of the hydraulic system;
- clogging of the filter;
- increase wear and corrosion of parts.
As a consequence, the equipment fails prematurely, there are risks associated with downtime or stop production, increasing maintenance costs.
How to choose a quality product?
for consumer products such as hydraulic oil VMGZ, features are equally important.However, a class of products offered by various manufacturers of lubricants, has about the same performance.This fact is due to the use of the same basic set of additives.In addition, each company trying to take a strong position in the fierce competition, relies on these or other important properties of the final product.For example, we can talk about anti-corrosion or temperature (marginal bracket point and fire) indicators.
Therefore, the rules to be followed when choosing oil VMGZ can be summarized as follows:
- Carefully read the enclosed instructions, paying attention to the product's generally accepted international standards (ISO, SAE).
- not to alienate entirely on the price segment, the main criterion should be the credibility of the brand.
Good luck choice and the smooth operation of your vehicle!
