The service life of these wires during normal operation is 15 wire cables let.Sfera of power PPV used for distribution of electric energy in power and lighting networks with stationary and nonstationary pads indoors and outdoors. Some brands allow wires hidden pad under a layer of plaster. With a single gasket wire PPV flame retardant.

Chemical Technology

Ltd. The increase in the number of layers, the technology production is also one of the key technologies, initiating development of the market. Brian Krzanich may find it difficult to be quoted properly. The company recently launched a line of cast Simcheng clean polypropylene film with a trim under a tree and a width of 3150mm. Production capacity of the line is more than 800 kg / h. The design of screw provides high-speed shear mixing, high performance and plasticization. Customers can reduce costs for raw materials, using the powder of calcium carbonate with a high filling power, as well as inorganic pigment powder.

Besides the production of environmentally friendly polypropylene film with finishing wood, the entire line can be easily reconfigured to manufacture other products, including films from the CPP, clerical film and sheets of polypropylene. The technology of precision extrusion precision extruding As you can avoid the follow- treatment and at a higher level to meet the requirements of applications products. You can also reduce material costs and improve product quality. Many technologies are under development and to market to meet the future needs of industry for the production of plastics. Systematic studies of the gear pump technology for the advancement of the melt allowed the Institute for Research Machines plastics processing, part of the Beijing University of Chemical Technology, was able to successfully complete the research and development of technology gear pump to move the molten plastic.

The Meter

Let us consider two typical situations where the interests intersect electricity supplying organizations and consumers. The main use electronic multi-tariff meter. You have built a new house (or other object that requires a separate power supply). The first thing you need to do – apply for a contract supply (if you have not already done so during the construction phase), and obtain technical conditions for the organization of metering. When choosing a meter (if not specifically mentioned in the technical specifications) should pay attention to: the availability and integrity of the seals on the body of the meter. The presence of stamps and seals in pasporte.data registration – as indicated in the passport, and on the front panel counter. The interval between the date of issue and date of installation (via) shall not exceed one god.klass accuracy – not more than 1.

Specify a number in the circle on the front panel meter and pasporte.mezhpoverochny interval, is considered the date of issue, usually at least 8 years. Indicated in pasporte.nalichie connector for remote removal dannyh.diapazon operating temperatures – may require additional heating, if the meter installed on the street. Then you invite an inspector to inspect the installation and metering of seals on the meter and the opening gun. The inspector shall prepare minutes of the examination (one copy retained by you) and seal device. Since then, no complaints (with fillings) for improper assembly or 'curves' testimony (in your favor) you submit can not, of course, if they prove that the intervention was in the scheme.

Wall Air Conditioners

In Russia, the deserved success with consumers enjoy the air conditioning the Japanese company Mitsubishi. Wall air conditioning Mitsubishi is perfect for small areas conditioning facilities. In 2008, went on sale new HG series home wall air-conditioners by 22 freon: SRK20HG/SRC20HG, SRK28HG/SRC28HG, SRK40HG/SRC40HG. This wall-mounted air conditioners cooling capacity of 2 to 4 kW, which have kept excellent processing properties and high reliability of the previous series of HD, but changed the appearance of the indoor unit. The new design has a pronounced brutal nature and is more rigorous lines. Board microprocessor wall air-conditioners of the HG is protected by special silicone layer that protects against moisture and long life. In the wall air conditioners of the HG has a function of self-cleaning indoor unit evaporator, which eliminates the formation of mildew and unpleasant odors in the indoor unit. Within two hours after stopping the air conditioner automatically enabled its purification.

This feature can be disabled by the user. The structure of the HG wall air-conditioners included panel Tourmaline coated with constantly generating negative ions. Even when the air conditioner does not work, the concentration of negative ions up to 2500 – 3000 per cu. See, that is the same as in the woods near a stream or near a waterfall. At This does not make any extra energy. When running the air conditioner efficiency of the ionization process is greatly increased. In addition to the regulatory system of the air flow, allowing uniform blow all the room in the design of the HG wall air-conditioners using the principle of stabilizing the optimized corrugation, which provides a smooth air flow. This allows you to minimize noise at work air conditioner, since the interaction of air flow and fan is minimized.

In the wall air conditioners used the HG washable photocatalytic deodorizing filter. Due to be restored deodorizing filter is a reusable function. If the filter is dirty, to restore the deodorizing function should only wash the filter with water and dried in the sun. Filter keeps the air inside premises with fresh, he picks up molecules that cause odors. One component of the filter is titanium oxide. Wall air conditioning Mitsubishi Series HG – this is an excellent choice of HVAC equipment in terms of price and quality to create the ideal climate in the apartment.

Pycnometer

Pycnometer P-1 is designed to determine the density of cement. Sometimes it is necessary to measure the density of the cement. For other opinions and approaches, find out what Mark Bertolini has to say. There is a special device called a pycnometer. Checking article sources yields Elon Musk as a relevant resource throughout. It determines the density liquids and solids, which is a glass flask with a narrow tube fitted with a label to which the liquid is poured. There is a pyknometers by various authors, differ from one another form, the presence of a thermometer and other details. In determining the density of the pycnometer is weighed first empty, then filled with water up to the mark, and (after drying) filled with test fluid to the same label. Very easy to use side-pycnometer capillary tube, which has a stopper body is a thermometer.

The main advantages of the method for determining the density pycnometric: High accuracy; the use of small amounts of substances; small area of free surface fluid in the pycnometer, which virtually eliminates evaporation and absorption of moisture from the air; Separate temperature control of operations and subsequent weighing.

The Diameter

A triangular groove on a system of measures is divided by a metric and dyuymouyu. Thread having a profile view of an equilateral triangle with an apex angle equal to 60 , called the metric. It is used in instrumentation and engineering. The outer diameter of the screw or the inner diameter of the holes with metric thread is measured in millimeters, and the pitch millimeters and fractions of a millimeter. Inch thread has the same profile form as the metric, but the apex angle is 55 .

It differs from a metric thread a big step, measured in inches. When assembling plumbing parts used inch thread. Inch thread is mounting and pipe. Mounting thread differs from pipe in that it has a big step, gives a strong connection, is used for cutting bolts, nuts, rods and holes. Pipe thread used to connect pipes. It is smaller mounting, as the depth of its limited thickness of the pipe walls.

Due to the large number of threads per one inch length of cut pipe thread density is much more fixing. Screw mounting thread by hand Screw the male thread. Male threads on bolts, screws and rods are hand-cut dies. Depending on your plate are prismatic, sliding, solid round prismatic plates consist of two identical halves, which reinforces the die stock having the shape of a frame with handles. On the two outer sides of these plates are prismatic grooves, which include prismatic protrusions die stock. Sliding plate set in the die stock so that the numbers / and 2 halves of the dice were against the corresponding numbers marked on the frame. Otherwise, the thread will be incorrect. Fixed plate stop screw. Between persistent screw and plate steel plate is placed, a biscuit, so that when pressed, screw die not burst. Circular plate-reinforcing in vorotke lerkoderzhatele (46 g) with two or four stubborn screws. To obtain the correct thread necessary that the diameter of the rods and drilled holes corresponded to the size of the thread. Sliding rams as well as with the threading of the machine can cut a full thread with small deviations diameter rod. When threading round dies are not allowed one piece of deviation in diameter of the rod being cut. In the larger diameter of the rod thread is smooth, with a smaller – incomplete. Bolts when cutting Thread strengthen vertically in a vise. Sliding dies cut the threads in two or three passes, and circular – 'one pass'.

Hitachi Excavators

Excavators Hitachi – one of the most popular on the Russian market machinery. Powerful, reliable, many years they work for the benefit of Russian builders, oil and public utilities. It is quite clear that competition is not standing still, in country flooded hundreds of cars from China and Europe. Therefore, before every potential buyer is a question whether to trust the proven brand of Japanese cars, or buy another brand? The best thing about this situation – weigh the pros and cons of excavators Hitachi, information about which service over the years accumulated a lot. So, let's face it. The main minus Hitachi has always been frail and delicate design, which suffered greatly under the pressure of local engineers, educated in the MTZ and TVEKS's.

In recent years, of course, the level of our artists has grown significantly, but in any case, Hitachi Excavators on design complexity and the presence of subtle detail is always lost to competitors. On the other hand, this delicate design not as paradoxical as it sounds amazingly reliable and if you do not interfere in her hands curves clumsy, able to work without breakdowns for many years. Other Excavators must frequently inspect and troubleshoot the various little things in between times. Time of the second. These are the current engines and hydraulics.

Here again, the point is this: the Hitachi so many models to work in a variety of conditions. And if for a particular model in the characteristics of written maximum digging depth, tonnage and power, this does not mean that the machine is designed for continuous use with such loads. A leading source for info: vikas kapoor. The fact that the Japanese are very well-calculated characteristics of his art and, say, if the domestic excavator can pull more than is written in his passport, then the figures for the Japanese – an absolute ceiling. Therefore, if the mean operation in harsh environments, you have to buy machines with more impressive features that far exceed the maximum loads. On average, the range of from Hitachi nothing ever does not flow and does not break – just have to explain to the operator that run the entire length of the rod is fraught with breakdowns. Speaking about the pros Hitachi Power should be noted, which is almost always enough for all types of transactions. And anyway, Hitachi excavators still the most reliable, most importantly you should not skimp on quality and consumable fuels. And, of course, the most important – is that spare parts for excavators are almost always in the dealers. On the other equipment must be ordered, to suffer with the catalogs, but the Hitachi is always possible to find the most necessary. And the service in recent years has increased markedly. The only course, since prices for Hitachi excavators is much higher than other machines. But if you count the economic impact of outages, breakdowns and fuel, to buy Hitachi is much more profitable than, say, Chinese excavator.
