Specialists from the company engaged in offshore Well, have proposed to establish a three-inch borehole pump grundfos type sqe. This model is equipped with integrated frequency converter, which allows for constant water pressure in the house, regardless of expense. Except how many of today's pumps, this unit is equipped with protection against "dry run", overheating, check valve, built-in voltage regulator, and equipped with soft start, significantly increases the life operation. Also, this pump can operate at voltages from 160 to 280 watts, which is very important when a very unstable power supply in summer and cottage communities. The choice of a particular brand pump is always done on the basis of two parameters: the water consumption (calculated by the number of parsing in the system – simply put, cranes) and the required head (taking into account the well depth, the height of the house and losses on hydraulic resistance in the pipeline). Points indiscriminately in the project at home was a lot. Kitchen sink, guest bathroom and shower on the first floor, bathroom with sink and toilet – in the second.
Also, the owner provided a sink in the garage, he said, "mud home does not carry, and a separate tap for connecting sprinkler system on the site. So that the peak water consumption has turned out not less than 3 cubic meters per hour. Based on the draft layout piping and the number of points indiscriminately, using computer program were calculated the required parameters for water-lifting equipment. Catalogue chose a particular brand of pump that is suitable for all characteristics.
Large equipment is an inevitable development trend Our government attaches great importance to the coal industry, coal washing industry gets rapid development, which gives feeding equipment industry development space, also brings market competition pressure. Feeding equipment needs to adapt to the new situation and meet the requirement for high quality and efficient coal preparation; Therefore, they should do as following. (1) Emphasis on fundamental research, strengthen the management of scientific research. Basic research formulate a test basis to optimize the product structure, improve the quality and reliability, reasonably select materials and promote the application of new technologies and new product development. (2) Accelerate the automatic measurement and control technology research in coal preparation process. Coal preparation machinery automation is unavoidable way to improve work productivity, ensure the operations safety and reduces coal preparation costs.
Despite the history of automation technology applications is long, there has been some technical imperfecciones, the introduction and application of automation technology in coal preparation plant is relatively slow. Today, computer technology, sensor technology and artificial intelligence have developed to a certain level and feeding equipment automation process will be accelerated. (3) Improve the existing equipment. As well as other industries, the application of modern technology in the feeding equipment is growing, but the existing equipment will continue to be used and will tend to perfection. (4) Strict control environmental pollution. Environmental pollution caused by the feeding equipment noise and dust is serve, so controlling environmental pollution is prescribed in the national standards. Large feeding equipment has the advantages of high efficiency and big processing power; in recent years, large-scale feeding equipment has been widely used in the domestic coal industry, Hongxing machinery commits to take innovation on vibrating feeder and other large feeding machine, making contribution to environmental protection.

And accordingly, the same increase in fuel costs. Think for yourself. Heating a private home: pipes Finally, you will need to decide on how the pipes in the heating devices will be supplied water. Widely used in the past steel pipes today are not used, because installation of time-consuming, but life is not so great (due to corrosion). In addition, repair or relining of steel pipe – not an easy task.
Also, experts do not recommend use in heating private houses so Viewed today composite tubes. The fact that they sometimes have a tendency to burst at the bends, while under the influence not so much pressure as the temperature. Therefore the choice of the best stop on a copper or a polymer (eg, made of reinforced polypropylene and cross-linked polyethylene) pipe. Copper the most durable and resistant to external influences and convenient for maintenance, but using it requires considerable financial costs. So in most cases the best choice for heating private houses will be polymer tube.
Of course, we have examined here, not all questions connected with the organization of the heating of private homes. However, the main covered his attention and the most common issues on which attention should be paid to the owner. Defining priorities for yourself, everything else you can solve by using the help of professionals. C housewarming! Heating of a private house: The price issue, but at what cost the same amount of heating of private homes? The answer to this question is not so easy, because a lot depends on your house, its layout and the existing needs. Experts call very different prices – an average of 1,000 to 2,000 rubles per square meter of heated area. You also need to understand that the more the house, the less will end up in terms of "square", because the changes only the length of piping and number of radiators, the boiler and the cost increases is not proportional to its capacity. For example, if you have a one-story cottage with a total area of 100 square meters, it is a reasonable approach, but without excessive economy, the heating system with gas boiler will cost about 150-200 rubles. While on a two-storey house of 300 m2 will take about 300-350 thousand. Specialists of "Ekokomfort" recommend to look beyond price equipment and installation, and on home heating costs in the long run. That is, the actual cost of the system to add the cost of its maintenance and fuel, say, over the next 20 years. And, dividing the resulting figure by 20 to estimate how much you will be heating annually. For example, as a result of this calculation turns out that the gas boiler ototpleniya, even with the cost of individual connection to the backbone, "eat" about 27 thousand rubles a year, while Oil and Electric – approximately 135 000.

By the function of sanitary water boilers are single circuit and double-circuit. Double-circuit boilers provide hot water heating without additional external devices include a flow-through heat exchanger or hot water boiler built. Single-circuit boilers are designed for space heating and, if necessary, separate heating boiler installed. By way of venting gas boiler flue and are turbocharged. Chimney pots – is a natural draft boilers. To install these need a chimney. Through attraction, the flue gases are removed into the atmosphere.
Burning in the boilers is supported by oxygen from the boiler room, because to the boiler with boiler flue imposed requirements on the flow of air. Turbocharged boilers – boilers with a sealed combustion chamber with forced removal from flue gas by a blower and fed outside air for combustion. The most commonly used coaxial tube. On the inside tube removed exhaust hot gases, and the outdoor air is supplied to the combustion chamber. Priority of such boilers – no chimney pipe coaxial output simply through a hole in the outer wall.
Gas condensing boilers are completely new principle of operation compared to conventional boilers. The advantages of condensing boilers: – high efficiency – up to 110% – heat exchangers made of stainless steel and have a period of service in 2.5 – 3 times more than copper heat exchangers, the probability of a compact placement at high power – Wall gas condensing boilers have a capacity of up to 100kW – thermal comfort – condensing boilers have the greatest efficiency at temperature 50/30, which is especially important when heating systems 'hot sex'. Electric boilers are quiet, easy to install and maintain, do not pollute the environment, but consume large amounts of electricity. Solid fuel boilers incredibly prevalent everywhere. Use them at a time when other forms of energy available, or horror of the road. With solid fuel boilers is not easy implement the basic problem of heating – keep the room temperature constant. One must always check the combustion process, coal underlay, remove slag and ash. Fortunately, the development does not stand still. There are: Solid fuel boilers long burning Stropuva. In the solid-fuel boilers of new generation Stropuva period of burning on one tab of wood – up to 30 hours, and coal – up to 5 days! So the greater length of the tab on one fuel – is economy of not only time and money, and comfort in use. In boilers STROPUVA laid an impressive amount of fuel that kindled and burns in the surface layer, rather than below as in conventional boilers. Thus, boiler best and most economical uses coal, allowing you to achieve high levels of efficiency. Solid fuel boilers with combustion of pyrolysis of wood and simple adjustment of power. In these boilers burn themselves do not firewood, and wood gas released from them under heat. This forms a very little ash. Service. Initial start-up of each boiler design and warranty produces a master service organization serving the boilers of the brand. The functions of the service in addition includes: warranty and post warranty repair, annual maintenance of boilers. Existence service center and spare parts necessary range of the boiler is an important criterion for selecting brand boiler, because boiler inevitably in need of repair and maintenance. Extension of the warranty on the boiler in excess of 1 year is service center at its mandatory annual maintenance.
