Today the Russian market offers more than hundreds of different boilers of foreign and domestic manufacturers. Which one you prefer? How not to make mistakes in choosing? Do not miscalculate the cost? It is best to entrust the choice boiler technician who will design the system for you heating and hot water. He will be able to provide the optimal combination of elements of the system will choose the pot, allowed to operate in the room where he provided for installation in your home, and will orient you on how to obtain numerous permits for the installation. But the final word rests with the developer, therefore, having heard the arguments designer, you have to make the final decision himself. Find out detailed opinions from leaders such as Charles Schwab by clicking through. From where should you start when choosing a boiler? First of all, of the type of fuel that will be most accessible for the long term in the construction area your home. It should be noted that modern boilers for liquid or gaseous fuels will run during the heating season in the automatic mode and does not require extra time on your part, for exception of seasonal maintenance work, which may produce utility service. Everest capital has plenty of information regarding this issue. But with boilers for solid fuels more trouble: they have to constantly load the fuel. Better if the boiler designed to burn any one fuel. In this case the construction of the boiler and the firebox will be optimally cootvetstvovat fuel and the boiler will operate at peak efficiency. Having defined the type of fuel, proceed to the choice of design Boiler, boilers, single circuit – designed to heat the coolant for the heating system or only the hot water system, or dual-circuit boilers – they are suitable for both heating and for hot water systems.
Cisco 2600 can transmit simultaneously to the two video streams at resolutions up to Full D1 (720×576 pix.) At a speed of up to 25 k / s formats H.264, MPEG-4 or M-JPEG. In addition, a surveillance camera has audio input / output, microphone, motion detector, and it can be used Day and night for a room. To configure the Cisco 2600 and control video from the camera can be used in Cisco Video Surveillance Manager, or third-party software. The high quality of transmitted images from the camera provide a 1/3-inch CMOS sensor and a modern processor, the video signal. For the video in a wide range of illumination with high-detail images in the Cisco 2600 is implemented high dynamic range (WDR), the maximum value reaches 120 dB. Due to the presence of the automatic white balance, backlight compensation and auto exposure, the camera generates video surveillance with high brightness, Contrast, sharpness and accurate color reproduction, and corrects distortions that can occur when shooting moving images.
Cisco 2600 has an aluminum housing that protects the camera from an electronic stuffing mechanical damage, and is designed for use indoors. Also, a surveillance camera can be used in unheated rooms or in outdoor conditions when it is installed in ThermoJacket. Because the Cisco 2600 is available without the lens optics for her chosen based on the geometry of the observed object and lighting conditions. In this case the manufacturer recommends the use of varifocal lenses with a focal range 3-8, 3.11 or 5-50 mm.
Depending on the type of shelves, addition to the standard of universal or basic rack with metal shelves, produce and other kinds of shelving. For example, the use of bread shelves wooden shelves or baskets, in the vegetable – metal sloping baskets in pastry and fruit – small plastic trays, etc. When choosing a rack to check with the seller of its characteristics for several key positions. 1. Dimensions. Height of racks in the proposed configurations can be very different – from 1 to 4 pm The best option is 2000mm in height: in this case to the top shelf easily reaches for a man of medium height. In warehouses, where you can use ladders, or when an acute shortage of retail space, set design height 2500, 3000 and even 4000 mm. Width shelves on average between 800 to 1200 mm.
Obviously, the longer the shelf rack, the lower the price per running meter, because the reduced number of supports, fastener, etc. However, strength characteristics deteriorate: can bend under the weight of the shelves are offered for products. Therefore the choice of the length of the rack depends on the mass and dimensions of the proposed product. The depth of the rack is determined by the width of the bottom of the base shelf 300 to 600mm. 2. The strength of the rack. Maximum load per shelf.
It is determined by such factors as the thickness used metal construction brackets and shelves. Additional indicators are the presence of a shelf bracket and ribs, the connection bracket shelves with stand (tripod). Strength values are indicated manufacturers and may reach 250 kg. 3. Cover racks also plays an important role. With heavy use, a common set of goods in the hard pack surface shelves can be damaged, and eventually rust. Color cover those parts of frame, which will be visible after installation of the goods should not pull the attention of buyers. Traditional colors – bright white, pearl white, light gray, Ivory, warm milk, etc. If the racks are used in the warehouse or the archive, then the color gamma is not important and the question is more about the ratio of the price = quality.

No matter how complex the hydraulic system, it always consists of various hydraulic units, interconnected pipeline systems. The quality of the data pipeline systems typically have been under stringent requirements, because of their reliability depends not only duration and reliability of hydraulic equipment, but also the stability of the entire hydraulic system. Important These components are the various piping systems weld and threaded pipe joints, which are mounted hydraulic and lubricating fluid system. These compounds are conventionally divided into two groups: terminal and loop-through. First serve for mounting on the ends of the pipe and connected to all kinds of pumps, blocks, hydraulic cylinders, etc.
The latter are mounted along the length of the pipeline and used to interconnect separate sites in the overall hydraulic system. Limit connections to complete cut-metal rings provide quick and reliable installation of pipelines using calibrated (Precision) of pipes. Due to strain a relatively soft material of the pipe with the introduction of a sharp edge cutting ring that runs from a much more durable material, sealing is achieved connection with hose pipes. In these compounds without reassembling the tie-rings and replace the pipe end preparation – is unacceptable. Typically, end-complete connection consists of cutting ring, the terminal fitting (or gon) and cap nut. Corner joints can be used to connect pipes with weld nipples, and in this case, locks the ring does not apply. The most commonly used reference materials are carbon steel, brass and stainless steel alloy. The standard is the use of ordinary carbon steel.
In this case, and end fittings, and coupling nuts have a special plating (Usually zinc or yellow chromate). It is worth noting that the most widely used in Russia and Europe have connections with metric threads and sealing cone 24 . Depending on the job Pressure connections are divided into groups: ultra-light, light and heavy. Properly chosen, taking into account the specifics of a particular hydraulic system, used for repairs, will minimize the risk of downtime and breakdowns hydraulic equipment, as well as significantly increase the safety of staff.
Elevator – mode of transport, designed for vertical movement of passengers and cargo. A modern passenger elevator can carry up to thirty people, and mine passenger lifts – up to a hundred people. The ordinary elevator moves with a velocity of 0.5 – 4 m / s, while the high-speed elevators can be 17 m / sec. Freight elevator can move up to 10 tons of cargo at speeds up to 1.5 m / sec. Elevators for residential buildings – an obligatory attribute of comfort and convenience, without which is impossible to imagine today's skyscrapers and conventional buildings. Hotyadaleko not everyone knows how and when they were created first lifts. Now we will tell the story.
Scientists believe the advent of the elevator in 1743. It was then in command of the French king Louis XV, who then passed 33 years in the palace at Versailles was built the first lift. The king did not like peretruzhdatsya and climb to the room of his mistress, located above a floor. However, the prototype elevator, familiar to our eyes, was established more than 100 years through the American EG Otis (1811 – 1861.). This man changed my life in a lot of work – worked in construction and mill, digging coach. In 1852, working on furniture factory, manufactures beds, Otis received an unusual assignment – design a hoist to lift the planks on the second floor. In 1853, the inventor discovered light freight elevator with the emergency brake, which breakdowns quickly in case of a rope.
Attic for installation of need for a couple of cubes of more boards and insulation than ordinary attic. Insulated attic – quite suitable for habitation in the winter with a reasonable heating. Warming loft (loft insulation) Construction attic to a greater extent than the lower floors are exposed to heat loss by reason of the lack of roof attic "thermal pad", as well as on the roof of the attic has a large surface contact with the outside world. Therefore, for the comfort and heat economy requires effective and thorough insulation of the attic. So maybe the attic insulation foam or styrofoam, as well as slabs of mineral wool on the basis of basalt fibers. At higher Attic insulation to insulant impose more stringent requirements, as well as to thermal compaction and its execution. This seal prevents warm air to penetrate through the sealing layer.
Attic Insulation must effectively retain heat at the same time should not "steal" extra inches of space. When the attic insulation is important to remember that the heat loss occurs not only through the coating, but also through the end wall. Therefore, gable houses also need to insulate well in line with modern requirements. Heat loss from the roof of the attic are large enough, so competently executed warming could have a mansard roof appreciable effect. Quality roofing permit with the state of thermal insulation can reduce heat loss by more than 3 kW and thereby significantly reduce the cost of heating homes.
