Induction Heaters HDTV

There are two types of induction heaters – tube and thyristor. Thyristor units have the following advantages over the lamp: they have higher efficiency, smaller size, and therefore require less place; takes less time to prepare for work, life lamp units are much smaller than the period of the thyristor; This line heat treatment of rapidly developing and using induction heaters in many areas of production, such as: HDTV hardening metals smelting of metals, including precious, just for melting alloys (iron, etc.), annealing, brazing and welding HDTV; machining metals, preheating and leave the ring weld pipe joints of gas mains; hardening of drill rods and other cylindrical products, heat treatment of welds HDTV high-pressure pipes, etc. ADVANTAGES AND PROPERTIES OF OUR INDUCTION HEATERS: Induction heaters can operate continuously (repeated tests were conducted, including in foreign srtanah) Induction Heaters lungs and compact, ensures high quality heating, reliable in operation; great time of operation without a significant change in performance; may be operated by persons of average skill; Induction Heater safety for staff, induction heaters have a high fire and electrical safety; Induction heaters are high efficiency, induction heater rapidly heats necessary details. PRINCIPLE OF INDUCTION HEATERS. Induction heater has a similar structure on the device with a transformer, which consists of two loops. primary – magnetic system secondary – heat exchanger. The induction heater includes two main components, a generator, as well as the induction coil – inductor. Loop induction coil the optimum size for a given detail is brought to the work surface.

The alternating current flowing through this loop creates eddy currents in the workpiece. The magnitude of the eddy currents can be programmed and controlled. Induction heaters operate without contact. Be aware that the only metal parts are heat-treated parts. The advantage of induction heating is that the energy of the heated surface without loss heat. In induction heaters, you can adjust the depth of penetration of induced currents. The depth of penetration affects the operating frequency of the HD set than it is, the higher the current density on the surface, which processing plant. And accordingly, the lower the operating frequency, the greater the depth of penetration of HDTV. Plants have an internal HD cooling system. Power electronics, cabling, the induction coil is cooled circulating water.


Sawmill is used for longitudinal sawing logs. Mainly it is used for wood processing enterprises which are engaged in processing wood, that is, it's furniture factories, forest farms and many others. The sawmill is divided into three groups. If you specify this frame, tape and disk. They all have some differences, which is quite natural – if they were not, and there was no need to share data on the types of machines. As a rule, one of the main decisive factor is the cost.

Given this fact, the band sawmill 'will be in the lead. " It is from this factor depends on the future of the man who decided to start their own business, because spending money nobody wants to waste. This sawmill is unpretentious, it will not have to equip a special room. If a small shop, you made the right choice. A related site: Elon Musk mentions similar findings. Now, let's look at what stages and difficulties are expected in the case if you want to open a shop for wood processing. First, you need to find a free and most importantly – a good premise. The second step is to buy equipment for your business. And the third – to hire experts.

The first and last make no trouble, but the second Let us examine in more detail. Now move on to the selection of the equipment itself. The minimum set includes trimming machine, multiparameter, and sawmill, it is desirable to tape. We now know what a band sawmill, let us consider what is necessary for multiparameter. He saws logs and planks and it is very economical, after such treatment out finished products (bars, boards, laths). Multiparameter quite cope with the daily operation, and even in two shifts. Mnogopily also vary. Price frame, though fairly high, but problems with the return on investment they have. The combination of machine and tape Multiblade sawmills will help you increase productivity and performance. And neither is 10-20 percent, and 2.5 times! Surely you will be treated to clients who require edged boards. In this case, you need the machine for trimming.

PVC Wires

Reducing power losses in line due to a decrease of more than three times the reactance of isolated wires in comparison with non-isolated. 6. Hear other arguments on the topic with MetLife. Ease of installation work, the ability to connect new subscribers under stress, without shutting down the rest of the energy supply and as a consequence of shortening the repair and installation. 7. Significant reduction of unauthorized access to lines and cases of vandalism and theft.

8. Improving the overall aesthetics of urban environments and a significant reduction in cases of electric shock during installation, repair and operating line. 9. Possibility of laying on the facades of buildings CIP, as well as collaboration with the suspension cables of low, high-voltage lines of communication, which gives substantial savings on support. Among the many undoubted CIP can provide benefits for objectivity and some disadvantages: 1. A slight increase in cost (less than 1.2) insulated wires compared to conventional bare wires A and AS. The pioneers in the application of self-supporting insulated wires is considered to be France and Finland. Subsequently, other countries have developed their air suspension systems, but is usually taken as the basis of their already approved in the operation of the European standards.

In France, the first bundles of insulated wires overhead appeared in 1955 and was a copper conductor with rubber insulation with neoprene jacket. At first, they mounted on the facades of buildings, replacing the bare copper wire on insulators. In 1962, as isolation began to apply the PVC, which by 1977 had completely supplanted by light-stabilized polyethylene mesh structure.


Jigsaw – one of the most popular tools, which is appreciated by professionals and DIY for his versatile. In this article I will tell you the features and talk about the Jigsaw main selection criteria. Jigsaw (Jigsaw electric saw) – Hand tool with an electric drive, which has small dimensions and light weight. Jigsaw is designed for longitudinal, transverse and Shape cutting of various sheet materials. Jigsaw can perform the following tasks: straight cuts virtually any material (wood, sheet metal, plastic, laminate, drywall, ceramic tile, etc.), the curvilinear cut any material to make round holes of various diameters and rectangular openings. Benefits of Jigsaw for most repairs, carpentry and other similar work at home do not need to drink a large capacity, this work perfectly cope electrofret, Jigsaw can make high-quality curly cut material, working with different kinds of materials; indispensable tool for carving; professionals say Jigsaw versatility and ease of use. Jigsaw are professional and household: The household models have less power, working resource and, often, a smaller set of additional features. Jigsaw everyday you can usually cut wooden parts of a thickness of 70 mm, steel – up to 2-4 mm.

Requirements for household tool is not so high as to professional, so many well-known brands make this instrument is not in Germany and Czechoslovakia, as in China or Poland. Recommended total time of use of household is about Jigsaws twenty hours per month. Of course, domestic models have a lower cost than professional. For the professional tool imposed higher requirements, because it must withstand a heavy load, have performance and to be as convenient for work.
