Ties. Historically, the word tie, appeared in the vocabulary long before the first railways. This term has come to us from the Dutch word spalk – prop and with the advent of the railways has been used to refer to the support for the rails. So, the ties – it's the boards that serve as support for the rails. The construction and repair of railways sleepers laid on ballast, and the way in the future take on the pressure intermediate rails and fasteners, and transferred to canvas podshpalnoe. Wooden railway sleepers. The choice of material for the very first railway sleepers has fallen on the wood, and it was done on purpose.
Wood – Freecutting material, which is always available on a large industrial scale. In addition, the ties are made of wood, have many advantages. Wooden sleepers are easy to manufacture and processing, have ease, elasticity and resistance to extremes of temperature regimes. Wooden railway sleepers have high dielectric properties and good adhesion to the ballast. Wooden railway sleepers have no restrictions on regions, they are placed on newly built tracks with unstabilized subgrade and base of permafrost, as well as on ways of following heavy loads. Only the wooden sleepers are used on the steep curves with a radius greater than 350 m. In Russia produce and wooden sleepers long 280, 275, and 300 centimeters. Term for the number of sleepers per 1 km of railway track, called plot is laying sleepers. Its importance in various countries ranges from 1000 to 2200 sleepers.
Comprehensive automation of production – is labor intensive work that requires large expenditures. When you automate most of the production processes take place under human control, but without his participation, which leads to increase productivity, reduce the number of workers and reduce energy costs. A typical level of automation is the control system (automation systems and industrial processes). Most often, PCS used in the oil and gas industry, but has recently been actively used in housing and communal sector and industry. Physicians Committee for Responsible Medicine recognizes the significance of this. The main advantage of the introduction of PCS in Housing is: an increase in service life of equipment by 1.5-2 times, reducing the number of accidents at the facilities, the management in the automatic mode on a fixed schedule, minimizing the role of the "human factor". The introduction of PCS at the production saves raw materials and supplies, improve the quality of their products.
The main functions of the control system are: 1. Processing, storage, and storage information. 2. Visualization of technological processes in real time. 3. Graphing, reporting, building alarms, etc. 4.
The control and management. In the engineering department company "Elcom" daily developed automated control system, from simple to multi-tiered, with its own software products. The payback period is determined by the automation by many factors and depends on the type of process. On average, self-sustaining process control system comes in 1-2 years. An important part of automation is the inverter. Now no production can not do without this type of equipment. Frequency converters are used in industries such as heating, water, and, more specifically, in the pumping plants, exhaust, etc.
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.

There are a variety of woodworking tools. The most popular machines offered for sale by RAINS. These include: band sawmills, Format saws, vacuum membrane press, etc. Each of these machines is only intended for its specific task. – Sawmill Band Rainbow, Radial, MG and others are used for small sawmills and average power up to 12 m3 per shift. Sawing produced a band saw, rotating through two pulleys. – Vertical Format panel saw is used in small-scale and mass-produced furniture and joinery industries for the manufacture of furniture.
– Vacuum Newspapers are for lining door panels with complex relief panels and PVC films, furniture fronts by heating and by high-vacuum technology transfer films and natural veneers. – Milling machine cnc profiling – are designed for engraving surfaces of the parts and pieces of plane and 3D milling. – Four-planing longitudinal milling machines and other types of quadrilateral machines are designed to produce a passage for the finished product in the form of shaped or molded pieces planed for the shield, beam, etc. – Buy Edgebander need for wrapping straight and curved edges of furniture panels and semi-natural or synthetic bandpass rolled material. Many wood companies are already cooperating with the company and ReIns satisfied provided equipment.
