Semitrailer - cistern. Designation and classification.
Tanker - semitrailer is designed primarily for the transportation of various liquids - oil, gasoline and similar products milk. Mostly they are used for transportation, pumping of oil products (light or dark) and short-term storage. Modern tank semitrailers differ by the presence (absence) of the pump and the engine power. Drive of the pump from the tank runs from power takeoff, abbreviation - COM. Drain the fluid from the trailers, tank or trailers is usually done by gravity, or through the pump. The pump is installed on the tractor. The set of equipment trailers, tank, usually includes installation of a pump, a pipeline system control valves. Besides, the equipment of tanks shall be part of the highway draining and filling of the lower, as a rule). High-alloy steel - an important advantage of tanks, exactly the kind of material they are made. Semitrailer - tank may have different shapes. The most frequent forms: эллипсоидная, that is, oval, round, rectangular or trapezoidal. In some cases, a tank semi - trailer can be done with a variable cross-section, which may provide a reliable distribution of load on all axes. A low centre of gravity gives полуприцепу stability when traveling with a large mass of cargo.
With regard to the reliability, strength, producers of semi - tank have given this topic much attention. Safety first. Engineers are always used in the designs of various tanks high technologies, and all their solutions provide passive protection from potential fire of transported goods, for example, at the traffic accident. Within most models of trailers, tank set walls and breakwaters. Currently in tanks semitrailers role of the so-called breakwaters performs торосферическое bottom. Is the bottom makes the whole construction is very high proportion of strength. A tank semi - trailer has in its design many different parts, spare parts. So, plumbing and drain collectors on most models are joined by special compensators (often they are made of rubber). Such compensators take in case of a collision, the load that does not violate the tightness of the tank. Section of the tank semitrailer usually has a volume of more than twelve square meters. As a rule, section offline.
Consider some kinds of semi - tank. They find application in many spheres of activity: нефтегазоперерабатывающая industry as well as food and many others, utilities, and so on.
For example, such a tank semi - trailer, as cement carrier is intended for transportation of cement, lime, gypsum, and other powders and powdered goods. As a rule, cement is a cylindrical tank (steel). They are fixed on a slightly beveled frame that is placed at an angle. Two types: саморазгрузка and loading, and automatic (pneumatic) respectively. In addition they are divided as to the capacity and volume of tanks.
Such a tank semi - trailer, as the LNG carrier is a cargo tank, the volume of which usually constitutes from 0.5 to two hundred cubic meters. They are intended for transportation, temporary detention and charging of any containers (usually fixed) and for gas balloons, car, etc. Semitrailer - cistern that resembles the following is a битумовоз. It transports bitumen materials, the temperature can reach two hundred degrees Celsius. They can keep the original temperature regime of bitumen and, if necessary, to warm up. In order not to lose working temperature, битумовоз equipped with a layer of fiberglass. In this article there are, of course, not all types of semi - tank, and only the most frequently used.
