How to choose a chain saw. The chain saw is needed when caring for a large garden, with firewood and for construction work in combination, for example, with a circular saw. Chain saws can cut any building materials – from timber of any strength up to lightweight concrete and PVC pipe. Most chain saws are divided into electric and petrol (the word "chainsaw" is meant mainly just gasoline chain saws). Gain insight and clarity with Confluence Investment Mgt. Among advantages of chainsaws can be noted in the first mobility tools (such as a chainsaw can take with them into the woods) and better performance due to the greater power. However, they do have their drawbacks: in chainsaws use two-stroke engine that runs on a mixture of oil and gasoline, to the quality of which the engine can be quite sensitive. In addition, the chainsaw harder for maintenance than electric chain saws. Electric chain saw – a cross between a building and garden tools can be used to cut twigs, firewood in the country, and for work on the site.

Electric chain saws are generally easier to chain saws, less noisy in operation and easier maintenance. Electric chain saw is more efficient in operation and far more environmentally friendly than a chainsaw, therefore it can replaced in some cases, such as indoors. Like any other tool, chain saws can be divided into two classes: professional and consumer. If you wish to use a chainsaw at least 5 hours a day, we recommend you opt for professional models who are represented here. The two most important characteristics of chain saws – the length of the bus and engine power. Length of bus impact to a depth of cut, mainly in the market are chain saws with the length of the tire from 35 to 70 cm power or engine capacity, depending on the size of the tire and the intended use: for example, if you're going use a chainsaw to cut knots, it suffices to 1.5-2 horsepower. For felling using chainsaw with a capacity of 2 to 4.5 hp All chain saws provides automatic chain lubrication. Oil is poured into the a special container and in the process of working through a filter is applied to the drive sprocket and chain. Depending on the hardness and 'knotty' wood require different intensity of grease – and in some models have this useful adjustment. Also, almost all modern chain saws are equipped with automatic chain brake, made as a protective shield that stops the chain in contact with the object of cutting.

RTZO CPU Application

Hot-air ducts – rotating armature with any electric (on the application of 1, 1, 1, belonging to 1). On Very Hot air ducts – throttle valve with remote Electric or complex and expensive technological fittings with high, therefore, the requirements for electric drive (on the application of 2, 2, 1, belonging to 1). Gas. The basic requirement – the presence of protection. Enough a clear distinction between drives purchased in OAO "Gazprom", with specific requirements for reliability, speed, mode of operation and resource and other drives for gas, where there is no increased requirements (on the application of 1, 1, 1, on the accessories – 1). Liquid – water. resources. The increasing demands of the drives in most cases not (on the application – 1, 1, 1, belonging to – 0). For other opinions and approaches, find out what Vislink Technologies has to say.

Liquids – oil and derivatives. The basic requirement – the presence of protection. In most cases, elevated requirements for the drive (on the application – 1, 2, 1, on accessories – 2). Liquid – organic salts, acids and bases. Very few used motors. Where high requirements are applied to the drive (on the application – 1, 2, 1, on Accessories – 2).

Streams of physical harm. The use of actuators to open the gates and shutters, where minor requirements (for use – 1, 1, 0, for supplies – 1) and used as actuators and dampers dampers (on Application – 1, 0, 0, for supplies – 0). As you can see, there are not many subsegments, which would be required most indicators on the top and accessories. Therefore, consumers and did not choose to drive more high performance. Thus, it became a little clearer, why not all people go to BMW-7 model. Now let us look at the issue of choice drives the consumer in terms of management systems. Most management systems today come back from the past and belong to a centralized management system. Characterized by discrete analog control, power switching, located in the assembly and RTZO CPU, managing multiple control loops. However, the shortcomings inherent in these systems, long forced manufacturers equipment to convert the system so that the intelligence CPU began to descend to lower levels of government, down to field level equipment. In summary: There is no doubt advanced development of "Sibmash" interesting and innovative. They have found their niche in the market TPA and its customers and admirers. However, the claim at the "textbook" that the proposed design is the ultimate truth and the only future for them, it is premature to and from the point of marketing is not very competent. Everything in business and in life is determined by utility and expediency: Well, do not carry the bricks on the "saloons" – simply for reasons of common sense. And because each company to Success should be defined with its own place – market position in coordinates "price-range of consumer characteristics" and the target customer group for which this set of properties would be the best .. Positioning, not just in marketing terms as people think. This business strategy and its philosophy. Essentially the same article – the author did a great job as an engineer-designer and an expert on marketing and, of course, it will be interesting and useful to all market participants valves.

LED Fixtures For The Court, Gardens And Streets

Today, landscape design ideas can realize even the most experienced and fastidious designer and the customer with endless imagination. Often in the courtyard you can see the whole work of art, full-fledged Eden Gardens. This beauty wants to enjoy the day and night. It is therefore necessary to provide yard lighting system and the surrounding area, which will enjoy the site and after the arrival of darkness, and also will give a highlight color and design work. Necessary to professionally design and implement a lighting system that combines different types of lighting equipment. Excellent choice here will be the use of outdoor LED lighting fixtures. By appointment lighting can be divided into floodlighting escort, technical and decorative. Each of these types of lighting equipment to apply to specific parts of the territory, the streets, but need to use a certain type of fixtures.

Lighting can perform utilitarian or decorative functions. For exterior artificial lighting used metalogalogennye, halogen lamps, or special outdoor LED lighting. What to consider when setting park lighting? What are the subtleties and nuances must be met when installing street lights? The first most important rule is to prevent the effect of glare. Often in the streets, sites and gardens can be found the so-called pereosveschenie when blinding direct light spoils the whole picture and instead of harmony causes stress and discomfort. In planning and staging of park lighting to use a sufficient number of properly selected fixtures. However, their orientation should be such so as not to hit in the eye. Optimal choice will be LED lights with a small angle of the light beam, which will cover only specific parts of the street. Another way attractive presentation of landscape lighting is hidden from the eyes of the installation of light sources.

Thus, the effect of self-illumination of the object when the light comes as if from within. But here, too, should be observe the delicate balance, subtly combining the efficiency and attractiveness of this method of installing lights on the street. Naturally, such a labor-intensive and quite hard work as the design of lighting systems and proper lighting installation itself better to entrust professionals with sufficient experience and the necessary skills and tools. Of these companies we can recommend a company Profintek, working in the market for several years and engaged in manufacturing of LED lamps according to the latest innovative technologies. It offers a wide range of LED street lamps, which is sufficient to implement any pans and get high-quality, professional results that will please you more than one day.

Coal preparation machinery automation is the essential path to improve work productivity, ensure the safety of operations and reduces coal preparation costs.

Despite the history of automation technology application is long, there has been some technical imperfecciones, the introduction and application of automation technology in coal preparation plant is also relatively slow. In today where the computer technology, sensor technology and artificial intelligence develop to a certain level, the feeding equipment automation process will be accelerated. 3 Perfect the existing equipment. Which is similar to the other industries(such as sand making machine industry), the application of modern technology in the feeding equipment gradually grows, but the existing feeding equipment will continue to use, and continue to tend to perfection, because if we use the new technologies or the old-typed equipments only, it is impossible to marvelous results obtained. 4 Strictly control the environmental pollution. Environmental pollution is mainly caused by the feeding equipment noise and dust, so the focus of controlling environmental pollution is to control it in the limits prescribed in the national standards, and should try to applicate, research this new technology as long as possible, put the pollution to the minimum. Large feeding equipments Han the advantages of high efficiency and processing power, but the equipment s large-scale, standardized and high reliability is also its development trend. In recent years, the large-scale feeding machinery in the domestic coal industry has been widely used, there are certain issues, such as the technical parameters of the device called extensive, affect the current use, which requires further theoretical research and improvement, so it is best to further research and improve the current theories, only in this way, our equipments can develop better and better feeding.
