In contrast, ultrasonic flowmeters have no moving parts, is almost not affected damage. For example, recently one of the laboratories of St. Petersburg from the city of Lomonosov sent for verification flow ultraflow the first series, released in late 1980. The device worked for over 20 years and continues to regularly serve so far. On the question of effectiveness is often the savings resulting from the use of fairly expensive solutions may not only justify their price, but also lead to increased profitability related processes. "Today, many executives are paying a great attention to the regulation of heat consumption. And it's really effective, but only if the records.
It is impossible to regulate an unknown amount of heat! Unable to set the task to reduce consumption without a clear picture of the current flow! Therefore, high-quality accounting is a prerequisite for economical use of energy, a cornerstone of energy "- notes Tatjana Kislyakova, director of sales and marketing representative of the Russian company Kamstrup, world leader in heat meters. Consider a typical example: as the installation of heat meters contributes to upgrading the heating system and improve its profitability. Consumers usually install meters per reduction in payments for utilities. According to Igor Polyakov (PEP "The Ninth Trust"), and integrated automation of heating systems cost about a quarter of heat (and money to pay for it) makes the transition to calculations by the heat meter readings. There is nothing surprising in this: fixed tariffs for heat are often overestimated, so the actual consumption is much less. If actual consumption is quite high, the consumer is seeking to reduce it by applying heat Automation (ITP, balancing, thermal control).
That is the result of the transition to metering of heat is the heating system first single home. In the future the process of gradually covers heating system as a whole. At first, the decline in consumption entails a reduction in income and thermal company, making an obvious need to increase its profitability. Manual heating forced to take measures to eliminate leaks, boiler automation, introduction of modern systems, scheduling, etc. All this allows us to significantly increase the efficiency of urban infrastructure and municipal services in general. One example is the experience of Cherepovets. Here metering devices equipped with 2 / 3 of all residential buildings, with the cost of thermal energy for urban consumers are among the lowest in the country, and heating system at its Cherepovets economic and technical conditions favorably with most similar companies in other regions. It follows that solving problems requires a strategic housing approach that takes into account not only immediate benefits. Then use efficient equipment at one site system stimulates increase its profitability and viability in general. Engineering Equipment in Utilities – this is the initial stage of development the largest branch of the Russian economy. On this basis depends on how advanced and civilized relations will develop in the housing and communal services. It should be understood that each element of such a complex system as, For example, heating, must work efficiently and smoothly. Only in this way can achieve the best combination of price – quality "services.
Clothes we wear today – the result of collaborative work of designers, manufacturers and tissues directly seamstresses. Designers are constantly creating new fashions. And in the shops, in turn, make the clothes for the fashionable sketches. It should be emphasized that all this would be impossible without high-quality sewing equipment. Sewing machines – a very important invention, which is perfect for both household and industrial use. Once sewing was only possible by hand with a needle.
This way of tailoring takes too much time and effort, and manually simply impossible to do perfectly straight stitches. Thanks to the sewing Hardware manufacturing process significantly faster and easier. To purchase a sewing machine that can satisfy your needs for sewing, not prevent read reviews, buyers about a particular model. Household sewing machines are usually more housewives, and industrial – factory. It does not matter what model of sewing machine you intend to buy, review it to help you learn about it capacity. Internet – the best way to find a left on typewriters opinion.
There are many websites providing information about the sewing machines and equipment of different companies. You will be able to compare the responses and select the most suitable model. Typically, advertising is not enough to the wise buyer made his order. Feedback from other buyers about this or that sewing machine sound much more convincing. The Internet as a positive and negative feedback so that you can make a choice and not a mistake. Prices on sewing machines are of great importance. Nature of man is that he always tries to save money and buy This a good product. Price sewing equipment is essential. You should not overpay for a model of sewing machine with lots of different operations, if you do not want to use them. Therefore, before making a final choice, think about why you want a sewing machine. Choose the best sewing machine – not an easy task. Nevertheless, reviewers will help you solve it.
Feature of electric motors for industrial use, along with increased efficiency, is more efficient cooling due to more surface area (20 – 30%). Consequently, they are significantly less sensitive to low voltage, phase unbalance and lack of cooling (caused by sediments on the motor caused by poor water quality). In addition, industrial electric motors more resistant to corrosion. It should be noted that the highest reliability of industrial electric motors have purpose, the protection of which is carried out mri device 75 or mp block 204. The asymmetry of the voltage and current is known, with minimal asymmetry current reaches the maximum efficiency of the motor and the longest period of his service. That is why the important uniform load on all phases. In theory, the same rated voltage must be applied to all three phases. As a rule, near the low-voltage transformers and occurs.
Note, however, that to prevent the raising or lowering the voltage on some phases of the network at full load all the single-phase units should be evenly distributed over three phases. This should be done, because such devices often operate in the mode of frequent on / off cycles and may cause the asymmetry (bias) phases. Phase imbalance can be caused by the asymmetry current in the lines elekroperedach, as well as worn or oxidized contactors. For a possible asymmetry in the chain need to enable the motor to the network to consult with representatives of the Utility Industry. Current asymmetry should not exceed 5%, while using the remote cu 3 – 10%.
