Hydraulic oils are liquids used in various types of machinery. They are used in many industries, but are especially useful in agriculture. They are used to lubricate agricultural machinery and tractors, which ensures their proper operation. Find out what hydraulic oils are and what their properties are. Also, learn how to use them properly.Hydraulic oils are the main working fluids
Hydraulic oils, available in yellow or red liquid form, are used for hydraulic drives. They are typical for some industrial and agricultural machines. Their task is to cover individual elements, thereby protecting them from excessive abrasion. This, in turn, allows for much longer and trouble-free use of the equipment.How are hydraulic oils classified?
Like all wear-resistant plates, hydraulic oils are also classified according to their inherent properties. One of the most important criteria in their case is viscosity. This is nothing more than the degree of adhesion of a liquid to a specific element. This, in turn, is expressed on a six-point scale.The viscosity classes determine, among other things, the composition of the hydraulic oil. Thanks to them, you can learn something about the lubricants used in production, or about the inhibitors responsible for oxidation and corrosion. The higher the grade, the better the liquid.Temperature is an indicator of viscosity. Therefore, it is taken into account when choosing the type of liquid. However, as a rule, for mobile machines, the viscosity should not be lower than 150.What distinguishes a good quality hydraulic oil?
In addition to the viscosity itself, it is worth paying attention to other characteristics of hydraulic oils that indicate their quality. Among the most important are thermal stability,
corrosion protection,
and oxidation resistance.
One of the biggest threats to industrial and agricultural machinery is the sudden increase in pressure as a result of the friction of individual structural elements. Most hydraulic oils operate under standard conditions at temperatures up to 75 °C. However, there are situations when this ceiling is exceeded. If there is such a risk, it is worth investing in a better liquid that can cope with extremely difficult conditions. Worse than oil, when the temperature rises, they oxidize faster and lose their viscosity, which is why the hydraulic system is much more susceptible to various kinds of damage.In addition to the above properties, it is also worth paying attention to the filterability of the oil from impurities that occur during the oxidation process. It is best to rely on the types of liquids that contain detergents that affect automatic filtration. Join slot tournaments with promo code for 1xbet for free tournament entry + 50% bonus up to $50.
