Aluminum Radiators

December 13th, 2016

For example, panel radiators, plate and tubular heaters, finned heaters truby.Klassy Heaters for design features are grouped into four categories: sectional, panel, pipe, plate. The basis of the sectional heaters are heating elements separate section, connecting the battery to the desired heat power. Sections can be made of iron, steel, aluminum or their alloys (eg steel and aluminum – bimetal). Models sectional radiators are available of varying heights, depths and widths. Tubular heaters Heaters consist of a vertically oriented curved steel tubes that connect the upper and lower reservoirs. Heat output of heater depends on the height, number of tube rows and width.

In the main panel heating devices heating element – is the rectangular panel is heated by circulating inside the coolant (water or antifreeze). The panel can be made of steel, concrete and other thermally conductive materials. At present, there are a large number of plate heating radiator. If you have read about Steve Wozniak already – you may have come to the same conclusion. They are all united under a common name convectors. Heating element of these devices are made of steel or copper tube, straight or curved, which planted thin metal plate (accordion, ribs or segments of thin-walled tubes). The whole structure can be closed by a cover, grille, or open.

Sectional, Tube and panel heaters are called radiators, plate – convectors. Steel panel radiators Steel radiators – is heating devices, which are composed of vertically arranged curved steel tubes or from the individual heating elements, steel sections. Steel subject to corrosion, so the radiators of this type is mainly used in indoor heating systems (cottages, low-rise buildings). Steel executed sectional, tubular and panel radiators. Cast iron radiators cast iron radiators – Heaters is produced by casting of cast alloy. Excellent physical and technical properties provided iron corrosion resistance and low hydraulic resistance. Cast iron radiators – is the oldest form of heating appliances fluid. Heaters are used in autonomous and centralized systems heating more than one decade. Today, thanks to modern technology, these heaters are experiencing a rebirth. Bimetal Bimetal radiators radiators – heating appliances is made of two metals (steel and aluminum). Internal frame heaters can be made of steel, the exterior – from aluminum. This design avoids many of the disadvantages of aluminum radiators, while maintaining all of their advantages, including high heat. In such aluminum radiators is not in contact with the coolant, so it can be any chemical composition. Rugged steel collector to withstand pressure up to 60 atm. Aluminium sectional radiators Aluminum Radiators – is the most youthful appearance heaters designed for installation in water heating systems of residential, public and industrial buildings. They consist of sections. Radiators have high thermal conductivity and are designed for a wide range of pressures (up to 16atm). However, aluminum radiators are sensitive to the chemical composition of the coolant in the heating system. Acidity water must be within the pH 7-8.

RTS Used

January 28th, 2014

For a long time as a shut-off and control valves used valves and gate valves. Very often it was the valves and valves made of cast iron and very high quality. Many professionals who work in the field of installation and operation of various heating and water systems, are well acquainted with the problems encountered when used as a shut-off and control valves of traditional valves – the need for an annual audit for the packing seals and O-rings, cleaning disks from pollution, the complexity of the emergency line shutdown in emergency situations, lack of integrity, high percentage of failures due to a fall or accident cheeks bolts. Besides all this, the valve has large dimensions and relatively heavy weight. Today is a good alternative to conventional valves and valve – Ball cranes. Ball valves are made of nonferrous metals with thread to the pipeline are already widely used in plumbing, heating, gas, heat and power to individual nodes and industrial facilities. On objects of power (CHP, RTS, boilers, CHP, on the pipelines of heat networks), and numerous industrial applications where high demands for reliability, according to applicable regulatory requirements (SNP, etc.) use reinforcement from ferrous metals (including ball valves) with a socket connection to pipeline limited. Shut-off valves of non-ferrous metals do not recommended for use in pipelines with a diameter greater than 50 mm, operating at high temperatures and pressures, as the strength characteristics of the housing and the threaded connection is much lower than the reinforcement of steel and cast iron flange to the pipe and weld.

Text Effects In Photoshop

January 2nd, 2014

On the Web so at least half of all the graphic files – it's all sorts of labels, captions, headlines, text, logos and similar font of the composition. They carry information, create a mood, attract consumers' attention to an absolutely trivial things. And in all cases where you need to make the text look any way unusual, Web-designers have to resort to the chart. There are lots of graphics programs, that allow you to work wonders with text and images. Photoshop is one of many such programs, but very often it is only in those cases where you need to create a collage of several mnogopikselnyh images and text. Text Effects in Photoshop is very popular topic, no less popular than, for example, processing or photo collage.

In Photoshop this is a lot of methods and techniques, you can achieve stunning effects by only one layer styles. A classic example of a text effect – gold text. This effect is often used in WEB-design, and it's a way to emphasize the solidity, solvency of the company and a means to demonstrate the banal bad taste, desire to show off. A golden glow from the text and glitter – it's always a holiday. What is the meaning of the gold? It represents the sun, enlightenment, wisdom. Carries the notion of greatness, excellence, wealth. In Chinese alchemy gold – is the essence of heaven.

In Christianity, on the one hand – it's pure light, nonsusceptibility corruption (even submerged in mud, it retains its purity), on the other hand, it is – and the secular idolatry wealth. The Egyptians gold – this is the flesh of the gods in the Hindu – the light, the immortality of the gods. In Photoshop there are many special ready-made styles, which make it easy to create a text of gold. It is possible and very easy to create this effect. You do not need to be professional enough to be able to work with layers and gradients. Gold text is always significant in itself and does not require a variegated colorful background. Looks good on black. Work wonders in schedule and not be afraid to experiment with the text!

Panasonic Air Conditioners

February 21st, 2013

Filter SUPER alleru-buster has been tested in recognized laboratories in Europe and has proven effective against most known allergens and 99% of the ultrasound system of air purification in combination with a filter SUPER alleru-buster can capture even the smallest contamination. Under the influence of ultrasonic waves dust and small particles stick together, and the filter traps larger particles stuck together. Quiet mode quiet operation reduces noise of the indoor unit by 3dB. A simple push of a button you limit the fan speed to such an extent that the air conditioner is virtually silent. Performance of air conditioning in Quiet mode is somewhat reduced. Automatic change mode allows the air conditioner to maintain the required temperature in a room without any user intervention in a wide range of outdoor temperatures.

If, say, instead of at night cooling, one must begin to heat facilities, air conditioning automatically switches to heating mode. Design vnutrenneogo unit not only meets the current trends, but also reduces the noise of air conditioners, as well as simplifies maintenance unit. Now, instead of laborious cleaning dusty grid need only wipe the front cover with a damp cloth. The dust does not accumulate, as occurs in normal air conditioning, so even without regular care conditioner looks neat. Most of the air intake (85%) occur on the upper side of the indoor unit, which eliminates the air sucked back into the processed air-conditioning.

Transport Technologies

February 23rd, 2012

The development of technology transport moved far ahead. Today, the drive is measured not only in their output characteristics: torque for a given speed and resistance to stress, but also on parameters dimensions, methods of adherence, weight, design. Popular types of general purpose motors are worm and coaxial-cylinder motors. Their popularity stems from the fact that worm gearboxes are compact, light weight, wide variation in methods of adhesion, good thermal stability, and coaxial gearboxes also highly resistant to axial and radial loads. Modern companies have long used the concept of a geared motor, which has so far only being developed by Russian plants. Gearmotor is a single hub unit, assembled by flange connection.

The advantages of such a modular system with respect to V-belt transmission are: compactness, higher efficiency in the drive, ease of maintenance (some types of gear does not require oil changes), high tightness, light weight aggregate. Let’s look at the advantage of a gear motor in practice. For example, consider a widely used in Russia such as gear 2 hours, having a classic V-belt transmission and compare it with analogue – worm gear motor, executed under the standard ISO. We specifically did not go into the brand manufacturer, because Most of the imported motors have similar characteristics with each other. In particular Comparative characteristics for 63rd overall dimensions with the gear ratio 40:1 and the induction motor 1500 rpm, 0.75 kW power would look like this: Gear 2h-63-40: Weight – 12.6 Dimensions, mm – 220h145h225 torsional moment, N * m – 120 Imported worm gear motor: Weight – 6.5 Size, mm – 146h103h174 Torque, Nm – 137 Thus, we see that in this formulation imported worm gear has a much smaller weight and size, which allows us to reduce logistics costs by optimizing the overall weight and dimensions of characteristics. High temperature resistant gear provided by a system of cooling channels, and quiet in operation due to reducing the error in the compounds of component parts.

In addition, the imported counterpart does not require oil changes and has a high performance seal, therefore, it requires no maintenance costs. Left compare prices data reducers. Average market price of the gearbox 2h-63 from manufacturers in 2008 was about 11 thousand rubles, imported gear around 8.5 thousand rubles. This type of analysis you can do yourself, if will get a directory of manufacturers, which must be specified device gear, the drawing and its basic characteristics. In our example, the conclusion is clear, but, unfortunately, many Russian enterprises design engineers continue to work in the old and modern drives do not lay in their projects. You should not consider this article as a call to use only imported motors. On the contrary, it demonstrates a choice that not everyone uses, as follows. I hope that this material will draw attention to the study of modern advances in drive technology, as an item of value engineering equipment.

Floral Garments

January 26th, 2012

Golden hands of these masters for centuries created floral designs for clothing, uniforms, camisoles, women's dresses, noble people, as well as on church vestments. We commoners embroidery was more modest. Embroidery by the end of XVIII century. it was a leisure activity, homemade crafts. Embroidery is a profession for many skilled workers with the appearance of various trades and crafts. Embroidery as a type of craft begins to develop and lead to the formation in different regions country of its artistic features of patterns, colors, shapes, composition and technique. Embroidery has been widely applied in our country for the national costume jewelry in the XIX – early XX century. Russian masters ornament geometric or floral holding at the edge of the garment in the form of straight bars.

Well-known Russian embroideries include: Vladimir verhoshov, Mstera white expanse, a Russian antique smooth, Orel call list, and Branco and others technology. Wide circulation in Russia has received gold embroidery on suede, velvet, silk, cloth and cotton fabric. Even the fur coats, fur mittens, leather shoes, girl's belt, kokoshniki, tunics, adorned dushegrei embroidery. Different peoples in different regions, villages, different techniques of embroidery (countable, free smooth, white or colored openwork, cross polukrest etc.) motifs of ornament, color of thread. At present a variety of folk embroideries patterns, ornamental motifs, colors and their locations. Patterns in ancient times consisted of some signs or symbols that people expressed their perception of the world and relationship to the incomprehensible events Nature. These characters were a means of communication.
