From 1 January 2010 the average increase in tariffs for housing services in Moscow is 26%, ie costs of homeowners will rise immediately to the "quarter". Increase the costs for residents of other regions of the country: average of 10-15%. But there is good news. In many cities in the new year will pay for the resources consumed (electricity, heating, water) is not on standards and on actual use, which is usually more advantageous for consumer. Thus, the average water consumption in Russia, calculated on the basis of 300 liters per day per person, ie, 9,000 liters per month.

For example, in Germany, thanks to widely installed meters, similar to rate is equal to 125 gallons per day per person. Thus, the difference with Russian regulations is 175 liters daily! Overestimated in our country and look at the standards of electrical and thermal energy. For example, installing meters to reduce the level of pay for heat for about 30%. However wrong to try to reduce utility bills only through the meter. "Save people, not meters. British can not afford himself to shave or wash dishes under running water. We say that we have big payments, and pour water on the left and right. Teeth brushing against the background of running water "- outraged Uel , ceo of the Chelnyvodokanal. In Europe, where the size of the utility bills much higher than in Russia, the desire for economy has been below the national character. A recent poll in Germany showed that up to half of the respondents turn off all heating in the rooms, leaving home even for a few minutes.

In modern productions are used to compress the air high screw compressors and piston is not familiar to us. Screw compressors emit little noise at work, producing cleaner air, they do not inherent harmful to human health vibration. Furthermore, it is screw compressors are capable of supplying a continuous flow of air, without the jumps and disruptions. All these advantages are achieved by introducing a mechanism special design. So, screw compressors are, in summary form, the two screws that rotate in opposite directions and thus drives the air between his teeth. Gradually, the air contracts and to the outlet nozzle it arrives already under pressure of several atmospheres (the exact characteristics depend on the model of screw compressors).

It is clear that such work has no vibration, no high-level noise, no other unpleasant phenomena. A movement of air between the screw goes smoothly, without pressure surges. The result – a stable and continuous operation of any pneumatic tool, connected to such a screw compressor. Screw compressors and do not require such frequent maintenance, as the piston. On average, inspection and prevention of such devices are held 2-4 times less than similar work for reciprocating equipment. Affects a smaller number of rubbing parts and simpler design of the working part.

However, the market offers not only the conventional screw compressors, working with oil in the compression chamber, but also more advanced oil-free screw compressors. The fact that the air is injected into oil mist means no need for further purification and complex filtration system. Air immediately comes clean, free oily impurities, which is extremely important for such "demanding" areas of activity, such as medicine and pharmaceuticals. Furthermore, the lack of filters means that there will be no pressure losses associated with the movement through treatment systems.

Channel is one of the types of profiles obtained in the manufacture of metal products. This type of rent is used in many steel structures, with a particular area of application is often dependent on dimensional parameters. This is, in general, and not surprisingly, given that the width of the letter "P" channel bars can range from 5 to 40 centimeters. And if the 5-inch profile could easily remind us giprochnye profiles, the 40-inch (Produced up to 12 meters long, and sometimes even more) – this is a real column, capable of withstanding considerable stress. But first things first. Channel 5 – this is usually an auxiliary part. It is often used specifically as further strengthened the design, if the frames are built of light constructions (pavilions, warehouses), but can be used as the carrier, if the total load is not too high.

Channel 5 is often available in a "doubling" as actually representing an already narrow version of the I-beam. This is the easiest and one of the most skirts of all kinds of channels. Channel 6.5 is actually an analogue open U-5, only slightly larger size and strength. True, it is only a section of H – shaped form. Varieties of channel bars 6,5 – a channel with parallel flanges, channel sloping internal faces shelves channel bending. Channel 8 relates to the construction assortment of metal. Channel number 8 is produced in two forms: 8U channel number and channel number 8P, 9m long, 11,7 m, 10m, 12m, and random length.
