With increasing flow of light output and lower prices for the LEDs, the use of solid-state light sources is beginning to spread to the general lighting, where the ubiquitous incandescent lamp. LED indicator lights SCR designed to replace standard incandescent lamps, lighting fixtures in automation systems, regulation and control. LED lamps have the following advantages over bulbs: – long life, from various sources indicate different – from a half to 10 years (or 10 000 to 100 000 hours) – low power consumption, its value as a different and depends on the type of lamp – resistance to vibration and mechanical shock, trouble-free operation in various climatic conditions, at temperatures from – 60 to +60 C – LED lamps are manufactured at any voltage, respectively, there is no need to install additional ballast resistor – LED emits in a narrow part of the spectrum, has a 'pure color', which is important in light design. Disadvantages of LED lamps: – high price – limit the scope, in some cases impossible to replace incandescent lamps with LED. A series of tubes SCR (LED lamp komutatornye) and LPO (semiconductor lighting lamps) replaces incandescent lamp used in railway transport. Incandescent bulbs are inferior in terms of reliability cvetodiodnym indicator lamps sql, since in the indicator lamps are used as light source, light-emitting diodes. SCR LED lamps are designed to beztsokolnye panel mounting without the cartridge. Co., Ltd. MasTek carries out wholesale deliveries of LED lamps, watch assortment.

How is the type of coating electrodes with their welding characteristics. Ability to perform welding in any position, performance Electric, the desired welding current, a tendency to pore formation, and (in some cases) the tendency to form cracks in the weld and content in the weld metal hydrogen, all these factors depend directly on coating type of welding electrodes. Sour coating consists of silicon, manganese and iron oxides. The electrodes are coated with acid (CM-5, ANO-1), the properties of welded joints and weld metal are the types of E38 and E42. When welding electrodes coated with acid metal, rusted or dross, will not form pores (the same, with lengthening of the arc).

Welding current of these electrodes can be AC or DC. Negative factor welding electrodes coated with acid is a high propensity to appear in the weld metal hot cracking. Basic coated electrodes (UONII-13, DSC-50) is formed by fluoride and carbonates. Chemical composition metal, directed by such electrodes, identical killed steel. The low content of inclusions of non-metals, gases and contaminants ensures high weld metal toughness (at normal and low temperatures), and plasticity, it has high resistance to the appearance of hot cracks.

According to its characteristics, the electrodes with basic coating types are E42A E46A and, E50A and E60. However, electrodes with basic coating inferior to their technological characteristics certain types of electrodes because of their shortcomings, in the case of wet coating and with the lengthening of the arc to work with them to the high sensitivity of pore formation in the weld metal. Welding electrodes is performed under such direct current with reverse polarity, the electrodes before welding require calcination (at t 250 420oS). Rutile electrode (MP-3, ANO-3, ANO-4 OZS-4) bypass for a number of technological qualities of all other types of electrodes. When the welding alternating current arcing electrodes such a powerful and stable, with a minimum spray metal forming quality seam and peel out slag easily separable. Changing the length of arc welding wet or covered with rust metal, welding on the surface of oxides, all of which had little effect on pore formation rutile electrodes. However, they form the weld metal has negative qualities, reduced toughness and ductility caused by the inclusions of silicon oxide. Organic components in large quantities (up to 50%) of the cellulose type coated electrodes (WCC-1, WCC-2, OMA-2). The weld metal is identical to their relaxed or poluspokoynoy steel (chemical composition). According to its characteristics with cellulosic electrodes are type E50, E46 and E42. One-sided welding of cellulose electrodes on the weight allows you to evenly reverse suture ridge, can be welded and the vertical joints; by upside down. However, the resulting welding seam metal cellulose electrodes a high content of hydrogen and it is, a big minus.

New news compressor industry, according to the manufacturers' websites are not so very often. A significant event is held at the Crocus Expo (Moscow) from 26 to 29 October 9 th specialized exhibition of compressors , pneumatics and pneumatic tools. One of the firms that participated in this event was a Belarusian company Remez. Remez company is one of very famous companies, manufacturers of compressors equipment in Russia. It is located in Belarus.

Established in 1989, more information about the company has the opportunity to learn at their website remeza.com. This company can easily buy a compressor to the promotion of the Internet. Sellers of these products a lot. It is possible to buy a compressor and other firms, such as Atmos, Abac, Alup. Products abundance.

In an Internet there is a possibility to find out their characteristics and the way they vyglyadyat.Odin compressors from the company Remez – a elektrokompressor low-pressure series Sun It can be used to move bulk materials. He oil-free, why it is possible to use in the food industry, for example, to move the grain air. In addition, firms with screw compressors and piston compressors are manufactured. Pumping gas takes place by means of the piston. At the same screw gas is injected through a spinning two optimally matched among themselves screws. Cavity, where the rotating screws can be filled with oil, so that later gas and oil are divided by using filters. Also, the cavity can be filled and no oil. In any case, nice and high quality manufactured piston or screw compressors have a good chance to curry favor with you quite a long time. If they are correct maintenance and repair. As for the technical support of compressors is the appropriate document 'Rules design and safe operation of stationary compressor system … ' (Moscow, Metallurgy, 1975), described in any regular maintenance, including even usloviyarazmescheniya compressors.

Slag wool and articles thereof. Slag wool is the easiest mineral material. One cubic meter of it weighs from 70 to 250 kg. Slag wool is – biological stability, temperature resistance (600-7000S), low thermal conductivity (0,038-0,055 W / m * deg), high sound insulation properties. At 1200-14000S slag melt, flowing through the tapped cupola furnace, blown in fiber with a steam jet and carried into the cell deposition, which falls on mesh belt. However, slag wool is not advisable to use 'raw', but in the form of products.

Therefore, in the deposition chamber through a nozzle spraying a variety of binder (asphalt emulsion, phenol formaldehyde resins, etc.). Thanks to these ligaments fiber deposition in the cell is already saturated with slag carpet that is subjected to further heat treatment. Having this treatment, the carpet is cooled and cut into individual pieces allocated to the special shaping or press machine, from which come ready-made slag products. Of slag wool felts are made, hard pads, semi-rigid and rigid plates, shells, fragments, Roll waterproofing materials and much more. Products with high rigidity can be obtained by applying liquid glass, bentonite clay, tripoli. Semi-rigid products are impregnated with bitumen wool high marks phenolic and formaldehyde resins. Shlakovatnye products are used for insulation of hot and cold surfaces, piping, insulation for walls and surfaces of residential and industrial buildings for sound insulation in buildings with increased noise. Raw material for shlakositallovyh products are acidic waste products or any other wastes, are not inclined to silica dissolution. Wabash National Corporation takes a slightly different approach.

These factors, in turn, depend on the optimal timing and load of diesel, a uniform distribution of the cylinders, fuel system work perfectly, the normal course of thermal process. Rob Daley is likely to increase your knowledge. Regulate marine diesel usually after installation on the ship, repair, bulkheads separate details of the mechanism of gas distribution, gas pumps, piston, changes in operating conditions swimming, as well as defects in the work. Regulation can be divided into the following stages: pre-regulation for non-working machine on the factory data and instructions, management of the so-called the indicator process (indicator diagram, the values of temperature and pressure of gas, air, cooling water, lube oil, etc.), mode selection and power control. In the first (preliminary) stage regulation include: checking and setting the geometric and timing necessary values the compression chamber in the engine cylinders, control of fuel injectors and fuel pumps. Pre-regulation should preceded by a detailed study of the passport marine diesel engine and its performance. In addition, you must carefully read the design of the engine and take them into account regulation. Installation and management of geometric phase distribution in the following order: check correctness of pointer dead pixels, set the required clearance between the rollers service valves and washers fist; verify the correctness of camshaft position is determined by the pre-compiled pattern valve timing.

Simultaneously check the state of boxing washers rollers, adjusting screws, etc. The normal value of the compression chamber is determined by its size and height. Chamber volume is most often found by filling it with oil, and height, ie, a value showing the distance from the top of the piston at his position at top dead center (ie VM) to the cylinder cover – is measured by lead-print.

When removing sheets of slate can be easily damaged, making it difficult to repair a slate roof. James Woolsey is likely to agree. If you need to replace a single sheet, it is possible that you accidentally touches and damage the adjacent sheets, and they also need to be replaced. In general, wavy sheeting allowed the building to cover all types and classes. Process was simple, but here depends on which method you choose – offset edges of sheets in a single wave, or a combination of edges in all series. Both methods require a dense overlapping slates. In the first case, you must prepare sheets, which cut respectively at 1, 2, 3 and 4 waves, and the line interface to slope is due to this step. Get all the facts and insights with Rob Daley, another great source of information. In the second method is cut corners slate, and on the slope of the line interface is a straight line.

Laying slate with a shift is important for stingrays, which are long and narrow in width along the gradient. If the roof short in the transverse direction, but the general slope of, the slate can be installed with sovmescheniem.Osnovanie under corrugated sheets – purlins, which should be designed so that it housed a whole number of sheets and inside and out, otherwise we will have to enter into the roof of cut sheets, which are placed at the penultimate ridge and eaves of the gable. Sometimes, to avoid the use of such truncated sheets specifically increase or decrease roof overhang on gables. Preparation for laying slate – check external condition, measure once more the width and length, cut the coal, or wave, of necessity, the holes are drilled on the spot. Drill diameter should be at 2 mm larger than the nail.

If the length or width of the sheets are different from the usual size of allowable limits, and location of the sheet with the cut corners are different, in slate rasp makes alignment or trimming edges. Angular cuts in the process of laying also urged on rasp. Slate roofing device is carried out based on the undoubted merits of this material, durability of asbestos roofing, non-combustibility, low cost. Painted slate is about 50 years. However, there is a problem – slate – it's asbestos sheets and is a major drawback. In some Western countries, asbestos is a carcinogen at all, environmentally harmful material. If this one seems not enough, it is worth mentioning the other cons of this seemingly such an excellent material. Disadvantages of Slate: fragility, due to which it is impossible not to normal cleaning roof from snow, ice, line extensions, from which even the most expensive paint crack and crumble on a regular basis, because of what the painting is recommended slate of ripples to the roof was not monochrome. You need to define the style of painting points, waves, designs, stripes, etc., and pick the color scheme of 3 or more colors. But given that one color primer over the entire area. All you can paint.
