Hot-air ducts – rotating armature with any electric (on the application of 1, 1, 1, belonging to 1). On Very Hot air ducts – throttle valve with remote Electric or complex and expensive technological fittings with high, therefore, the requirements for electric drive (on the application of 2, 2, 1, belonging to 1). Gas. The basic requirement – the presence of protection. Enough a clear distinction between drives purchased in OAO "Gazprom", with specific requirements for reliability, speed, mode of operation and resource and other drives for gas, where there is no increased requirements (on the application of 1, 1, 1, on the accessories – 1). Liquid – water. resources. The increasing demands of the drives in most cases not (on the application – 1, 1, 1, belonging to – 0). For other opinions and approaches, find out what Vislink Technologies has to say.

Liquids – oil and derivatives. The basic requirement – the presence of protection. In most cases, elevated requirements for the drive (on the application – 1, 2, 1, on accessories – 2). Liquid – organic salts, acids and bases. Very few used motors. Where high requirements are applied to the drive (on the application – 1, 2, 1, on Accessories – 2).

Streams of physical harm. The use of actuators to open the gates and shutters, where minor requirements (for use – 1, 1, 0, for supplies – 1) and used as actuators and dampers dampers (on Application – 1, 0, 0, for supplies – 0). As you can see, there are not many subsegments, which would be required most indicators on the top and accessories. Therefore, consumers and did not choose to drive more high performance. Thus, it became a little clearer, why not all people go to BMW-7 model. Now let us look at the issue of choice drives the consumer in terms of management systems. Most management systems today come back from the past and belong to a centralized management system. Characterized by discrete analog control, power switching, located in the assembly and RTZO CPU, managing multiple control loops. However, the shortcomings inherent in these systems, long forced manufacturers equipment to convert the system so that the intelligence CPU began to descend to lower levels of government, down to field level equipment. In summary: There is no doubt advanced development of "Sibmash" interesting and innovative. They have found their niche in the market TPA and its customers and admirers. However, the claim at the "textbook" that the proposed design is the ultimate truth and the only future for them, it is premature to and from the point of marketing is not very competent. Everything in business and in life is determined by utility and expediency: Well, do not carry the bricks on the "saloons" – simply for reasons of common sense. And because each company to Success should be defined with its own place – market position in coordinates "price-range of consumer characteristics" and the target customer group for which this set of properties would be the best .. Positioning, not just in marketing terms as people think. This business strategy and its philosophy. Essentially the same article – the author did a great job as an engineer-designer and an expert on marketing and, of course, it will be interesting and useful to all market participants valves.

Today, landscape design ideas can realize even the most experienced and fastidious designer and the customer with endless imagination. Often in the courtyard you can see the whole work of art, full-fledged Eden Gardens. This beauty wants to enjoy the day and night. It is therefore necessary to provide yard lighting system and the surrounding area, which will enjoy the site and after the arrival of darkness, and also will give a highlight color and design work. Necessary to professionally design and implement a lighting system that combines different types of lighting equipment. Excellent choice here will be the use of outdoor LED lighting fixtures. By appointment lighting can be divided into floodlighting escort, technical and decorative. Each of these types of lighting equipment to apply to specific parts of the territory, the streets, but need to use a certain type of fixtures.

Lighting can perform utilitarian or decorative functions. For exterior artificial lighting used metalogalogennye, halogen lamps, or special outdoor LED lighting. What to consider when setting park lighting? What are the subtleties and nuances must be met when installing street lights? The first most important rule is to prevent the effect of glare. Often in the streets, sites and gardens can be found the so-called pereosveschenie when blinding direct light spoils the whole picture and instead of harmony causes stress and discomfort. In planning and staging of park lighting to use a sufficient number of properly selected fixtures. However, their orientation should be such so as not to hit in the eye. Optimal choice will be LED lights with a small angle of the light beam, which will cover only specific parts of the street. Another way attractive presentation of landscape lighting is hidden from the eyes of the installation of light sources.

Thus, the effect of self-illumination of the object when the light comes as if from within. But here, too, should be observe the delicate balance, subtly combining the efficiency and attractiveness of this method of installing lights on the street. Naturally, such a labor-intensive and quite hard work as the design of lighting systems and proper lighting installation itself better to entrust professionals with sufficient experience and the necessary skills and tools. Of these companies we can recommend a company Profintek, working in the market for several years and engaged in manufacturing of LED lamps according to the latest innovative technologies. It offers a wide range of LED street lamps, which is sufficient to implement any pans and get high-quality, professional results that will please you more than one day.

1.Elektrody with a sour finish. The basis of coating are manganese, silicon and iron oxides. Welding seam created by the welding electrode with such a coating has prone to the appearance of hot cracks. 2) electrodes with basic coating. The basis of cover are carbon compounds and fluorine compounds.

Welding seam is different positive effects such as plasticity, shock viscosity at normal and low temperatures. But this kind of coating has a negative quality, it is very susceptible to the formation of pores in the welding seam in the presence of scale, as well as oil on the edges of the elements. 3) Welding cellulosic electrodes. This type of coating contains in its structure a huge amount of organic components, mainly cellulose, as well as substantial amounts of hydrogen. Welding electrodes with the type coatings are used in manual welding of carbon steel billets.

4.Elektrody Rutile. This coating contains about 50 percent of natural rutile concentrate. When using these electrodes stability of the welding seam to the formation of shrinkage cracks above. Gas emissions during arc welding electrodes, with this kind of coverage is not particularly harmful to the welder. Rutile electrodes provide a powerful and steady burning electric arc discharge with manual electric welding in alternating current welding, small metal loss during spraying, rapid slag formation and good weld. Important role for arc welding and electrical industrial manufacturing of the electrodes has a graphite MPG. What is graphite? Industrial graphite – a material that represents the allotropic forms of carbon, which characterized by a particular crystal structure. In turn, this structure is precisely defines the necessary properties of matter. Graphite has a great diversity of physical properties of different types of connections carbon, due form and size of individual groups of crystals, and crystal structure. Industrial strength graphite is entirely dependent on its structure. Each field has its own graphite physical attributes. And this difference causes the difference in the dispersed structure, that is a different shape and arrangement of crystals of graphite, which compose the body. Graphite is used in many industries industrial production, since it consists mainly of carbon and always contains impurities of ash, volatile matter and moisture. The main features in the manufacture of electrodes, which has industrial graphite – plasticity.

The problem of obtaining a license for water wells has become the most urgent in recent years. Since Soviet times, remains a huge amount of underground water intakes, operated without a valid license for unapproved stocks. Most often, the wells are operated for three to four decades and the issue of their legal registration, to a certain point, no one thought to do. In the 90s it's time to large urban artesian wells. For most of them were performed on the licensing, organization of monitoring, evaluation and revaluation reserves.

It is quite logical to expect that more will get to Rosnedra single intakes, on the balance of legal entities. What's happening. The works here – no end, but if you make long-term prognosis, then someday it will reach the common people, ie to private wells. But do not get ahead of ourselves. This article has a specific purpose – namely, to understand what must be the owner of the well, to safely issue a license for extraction of groundwater.

Fundamental point in the operation of water wells is the fact that subterranean water minerals. Accordingly, the owner of the water well used for the purpose of extraction of groundwater is subsoil. In accordance with Russian law on February 21, 1992 2395-1 On Mineral Resources", the provision of subsoil use is made of a special state permission in the form of licenses, including the prescribed form with the form National Emblem of the Russian Federation, as well as text, graphics and other applications that are an integral part of the license and determine the basic conditions of subsoil use.

The advantages of CHP is: Low cost of produced electricity and heat efficiency of the CHP far exceeds the efficiency of traditional steam turbine CHP multi-fuel: the possibility of using waste as fuel, associated gas in oil extraction, wood waste during the sanitary felling flexibility in the design, execution and use a wide range of technological schemes to generate electricity and heat in the form of steam or hot water cooling (water with a temperature of 12.6 degrees) for air-conditioning as possible to bring the production of energy to consumers, and consequently, reduce the length of networks, reduce the cost of their construction and maintenance of ecological safety advantages of quick payback Cummins piston units in the construction of mini-CHP is a low fuel consumption, a large engine-service life, reliability and durability. One of the difficulties that accompany the introduction of small power facilities, is the lack of customer service experience of similar equipment. (Source: David Fowler).
