Industrial Oils

Variety of technical oils in the oil industry Product of paramount importance to ensure reliable operation of various equipment. According to the purpose the basic technical oils are divided into lubricating oils and coolants. For lubricating oils include species such as: turbine oil for lubrication of bearings and turbine of a high degree of purification, oil for slideways having high viscosity; marine oils forming the emulsion is not washed with water, oil deep compression degree of purification, oil for aircraft engines and cars, and others. Where the application of technical oils impractical, used grease, which are semi-solid product dispersing additive in a liquid lubricant. The use of grease lubrication can deliver to places where there are difficulties in the use of liquid oils in view of a number of reasons, such as the inability to provide a sealed cavity, the difficulty in replenishing grease, etc. Coolant and refrigeration oils combine the properties of the coolant and lubrication, allowing both to ensure efficient heat transfer and surface protection against damage, corrosion, external factors or from wear due to friction. Since each species has its own technical oils special properties, there needs to be carefully selected (often in the laboratory) formulations of production.

The classic version of the receipt of a turbine oil, oil for slideways and refrigeration oil for a long been considered a way of obtaining them by the distillation of oil residues. These specifications are known as residual oil lubricants. The main drawbacks of this method are well known – it is the dependence of properties of oil from oil grade (From its initial properties), the need for deep cleansing oil, a large variation of parameters, etc. Another option of obtaining technical oils based on the alkylation of aromatic hydrocarbons or olefin polymerization (Ethylene, propylene). These oils are called synthetic. At the moment, a very high percentage of oils, which meet high standards, is the leading oil companies such as BP, for this technology. The recipe, developed by BP technologists can, for example, to obtain dispersion parameters of BP Oil in no more than a few percent, which is totally inaccessible to the result of mineral oils.

Forged Wheels

The most popular discs for vehicles today are light-alloy wheels of metals. They are divided into two types – a light alloy wheels and forged. Alloy wheels are usually made of magnesium alloys and aluminum. Forged in Essentially, all made from the same materials, but a very different way. Forged wheels are produced by hot pressing, and then go through the process of artificial aging and hardening.

Worldwide, it is considered that Forged wheels – an advantage wealthy car owners. And this is true, but in Russia there are several companies who have inherited the expensive equipment from the Soviet era, and yet they can afford production of relatively cheap forged wheels, which differ in price from western counterparts in several times. Because of technology, these discs is a little lighter than the cast, but they are much stronger, less brittle and quite suitable for repair. In the bumps, these discs do not break or crack and warp. But it is precisely this strength and is a minus forged wheels. Here, Alton Steel expresses very clear opinions on the subject. For example, hitting the hole, the drive will not blow over, and pass it suspension, is clearly not designed for such loads. Designs and different shapes that appear when you select cast wheels, forged wheels have not found. This is due to the fact that the manufacture of molds for them are extremely expensive.

In general, the forged wheels is the best option, which combines the advantages of steel and alloy wheels. But just such an important consumer characteristics such as price, makes for many, this drive is extremely expensive pleasure, because it exceeds the price of light alloy wheels in a few times. Also, it is sometimes difficult to distinguish yourself from forging casting. There are only a few indirect signs. Of course, the most common way of marking a difference. Private labeling for Forged Wheels – impressed, while alloy wheels – convex (spilled). ts on the topic. Typically, this method is one of the most reliable, because labeling is associated with a feature of production, but if the disks are made to order or tuning shop, these symptoms can vary. Forged wheels are indicated by the manufacturer FORGED, and cast CAST. But these signs are rarely applied to the disk itself, and in cases of production CD in China, or Turkey may be instances of just such application on the disc surface. Another sign of the difference between a disk shape and weight, the drive will be harder to cast wrought, but only if the quality of foreign goods, Russian drives for virtually the same weight. The form is in forged wheels, due to their special handling and a smooth point. Well, another sign of the difference is – the price. A good quality forged disc foreign production, the cast is much more expensive. In any case, the choice of wrought or cast disc for the car, purely personal decision. After all, the real characteristics of the disc depend on the precision technology and quality of the alloy. From the point of security is much better to buy a proven quality alloy wheels, forged than unknown quality.
