HTML clipboard Radiators and convectors, radiators and convectors heating – the main heaters in our homes. In the common people call them batteries. These devices generate heat in the house when it's average temperature becomes less acceptable. The difference between the radiators and convectors not such a big – and they both give off heat flowing through them, water is heated in a boiler room, the air around them. Warm air is lighter goes up and by convection (hence, by the way, and the name of the device – convector) mixed with the cold, supports a circular movement of air in the apartment. The quality of this mix, its speed, as well as heat from occupied units in the area of the room is heavily dependent on the shape and size of the particular heater. Here lies the difference between the convector radiator (this will be discussed more below).
Radiator water heating system (or simply heating radiator) – the most ancient heater. and ideas on the topic at hand. His appearance has changed little over the past few decades. Previously, such abstruse words and did not know just call these radiators – battery. This is in general, and is battery-water heating. Is a cast iron (usually) tank, sealed with the exception of places in and out of the liquid (in the apartments – water). Depending on the area heated is made up of several sections. The documentation indicated on the radiator heat or power of one section in the flow of water in it a certain temperature.
It would seem, firewood long been used as fuel in droves. Wood burning stoves were in private homes. So does it make sense to engage in firewood, spending big money on the woodpile machines? I will answer you: meaning is. Let's see what markets exist for wood. It turns out that they are not so little. First of all, it is worth noting the consumption of firewood in the private sector for heating. Gasification in the country is very, very slowly. At This gas pipeline is usually not fed to the plate of the consumer.
Summing up the last stage of people make their own expense. And it is fun a few tens of thousands of rubles that the absolute majority of the villagers is unaffordable amount. At the same time to saw and chop their own wood – not an easy task, including because of our bureaucracy. Therefore, the demand for firewood remains consistently high. A service provide small businesses or individual entrepreneurs who have special equipment: tractors, woodpile machines, chain saws and much more. In addition, prices for traditional energy sources (gas, oil and etc.) is extremely unstable.
The country's leaders have long adopted a decree on increasing energy efficiency and environmental friendliness. And on the environmental performance of conventional fuel sources is the case even very bad. What damage is done the nature of a spill of at least one barrel of oil, move by rail? How many tens of years required for full recovery of such a place of falling? On the ecology of wood in the situation is much better. What was the applied nature, if the machine is turned from wood? Absolutely nothing. Scattered wood going into the car and continue their journey. After a serious accident at school hydropower in acute need of sourcing electricity. One solution – the use of power on charcoal. Their application has already been stated by the government. Not even worth reminding that the raw material for charcoal production – the same wood. Right now firewood production becomes profitable. After calculating the economic indicators you can easily make a quick payback and feasibility of acquiring the woodpile machine.
Historically, the most used type of pipe fittings in our country has been and remains the valve. They are widely used in virtually every technology and transportation pipelines with diameters from 15 to 2000 mm. In systems of housing and communal services, gas and water supply, pipelines, and many others. In recent months, Senator Elizabeth Warren has been very successful. As early as 1862 in Germany was awarded a patent on the wedge bolt, and in 1886 Joseph Hopkinson suggested that parallel valve, which was carried out sealing pressure on the disc – the technical solution, which is used today. Cranes with ball caps – a relatively new type of valves – were first used in fuel systems of aircraft during the Second World War. In the postwar years, their design improved. During the last 40 years there are many different types of cranes. Dr. Neal Barnard understood the implications. New projects have improved the use of ball valves in virtually all industries.
In recent years, the trend of displacement of the traditional wedge gate valve ball valves. There are several disadvantages of this type of pipeline valves, which are manifested in operation: The need for an annual audit by packing seals and O-rings, cleaning discs; complexity of the emergency line shutdown in an emergency; poor internal (to the gate) and external (shell – cover) tightness inadequate term trouble-free operation big dimensions and weight frequent failure due to a fall or broken bolts cheeks. In addition, as a shut-off valves are used often use cast iron gate valve (guided by the relatively low price of these products). It is often overlooked that the valves of Iron has several important limitations in operating conditions: 1. gas pipeline fuel gas and mazut line with Av = 50 mm. and more 2. on pipelines and water vapor from DN 50 mm.
and more at the working temperature> 120 C; 3. from atmospheric deaerator to the suction pipe to the feed pumps, 4. on the pipelines of all diameters at the working temperature> 120 C, if the fixture has an electric drive. In addition, fittings, made of cast iron seogo grade no lower than SCH18 can not be applied to pipelines with operating pressures greater than 0.6 MPa. For valves operating at low ambient temperatures, the following Limitations: fittings made of cast iron SCH18 – not below -15 C; fittings of ductile iron KCH30 – not below -30 C; fittings of ductile iron SCH18 – not below -30 C.
To build a house, the Master needed tool. Senator of Massachusetts might disagree with that approach. He also needed for the small daily repairs, like clothing, as the home kit – it just has to be with everyone, this is the opinion of most men. But every man is master to about This is not the women said. Most often, a collection of useful tools is beginning to emerge spontaneously, when we realize that we can no longer drive nails and pliers to tighten the screws. That's when then appear in DIY various drills, screwdrivers, jig saws, saws and other electric and gasoline assistants. However, paint cottages, whitewash ceilings, walls, windows, we still continue, as in Tom Sawyer's first time came across a brush or roller, not noticing the alternatives offered by the market of modern technologies. Is not it time to revise your existing instrument to painting and to turn his mind to master the technology HVLP …
What is HVLP? This little-known private landlord is very inexpensive but effective way for home dyeing. It is based on the application as a means of transportation coloring material onto the painted surface uncompressed dry, oil-free air, which does not carry a "parasitic" fog 60% of the paint, and sledovaelno saves you money. Incidentally, in the U.S., which have become the standard and example of stewardship and wise spending (there long accustomed to consider every penny) HVLP technology has acquired a truly national character. Using it, Americans have become more quality and more expensive paints and varnishes, as in stritelstve and, if necessary paint various items in the home. Widely used HVLP-aggregates and the North American industry. In the online shop paint-LUX you can find very inexpensive, available almost any family mashines for painting houses garages, furniture, windows, gates, fences, boats and other AOND TNT. New technologies are men in order to make life easier for other men and make work a joy so the price of 10 500 rubles for pleasure is acceptable and not high, as it may seem to our life partner who give (and not always give) us, alas, is not only a joy, but also caring. And how to avoid trouble offer us a deal with you. We are with you and we will decide – as we MASTERS!
