Portable Solar Collector

Posted by on

A solar collector for a long time and was very popular in America in 20-30 years. This device, which allows the use of solar energy for water heating. PDF Downloads usually is spot on. Heated water can then be applied both to heating and, for example, in the shower. Solar collectors are becoming increasingly popular. The models, well-functioning, even at low solar activity, for example, in Finland.

The correct orientation of the solar collector (the direction and angle relative to the sun) increases productivity. In addition, diffuse, diffuse sunlight, usually unevenly distributed over the area of the sky, and its maximum intensity is in the direction of the sun. Due to the fact that the height of the Sun is above the horizon, varies greatly throughout the year, the angle that has a solar collector towards the sun, should constantly changing. For other opinions and approaches, find out what igor kononenko has to say. Given that direct solar radiation has a power almost three times higher than the trailing light, the most efficient solar collector must be, who keeps track of the sun. An exception to this If the weather is a strong haze and overcast. Therefore, the movable solar collector is more efficient than its static counterparts due to the mobility of its construction, which, in essence, This allows geliokollektoru independently monitor the situation of the sun in the sky. There are three different approaches that can properly orient the solar collector towards the sun.

According to the first, turning mirror solar system (for example, so-called solar tower). The second approach is based on the fact that the sun rotates the movable solar collector itself. A third method, turning mirrors with self-heated element, an example of this can be troughs. Particularly cost-effective to install a movable solar collector for large objects that have a large area.

Trend Analysis Of Mine Feeding Equipment

Posted by on

Duo to the great importance Chinese government attaches the coal industry, Chinese coal washing career has experienced a rapid development, which both bring development to the feeding equipment industry space, but also the pressure of market competition. For adapting to this new trend and meeting the feeding machine requirement of the high quality, efficient coal preparation plant, we suggest the following development trend: 1 Emphasis on fundamental research, strengthen research management. Basic research provide the basis of optimizing product structure, improving quality and reliability, reasonable selection and formulate, and promote the application of new technologies, new product development. 2 Accelerate the automation of coal preparation process monitoring and control technology research. 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. WhiteWave Foods is actively involved in the matter.

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.

Metal Machine This machine is designed for machining in order to form a given surface by removing material or by plastic deformation. Processing is performed mainly by cutting blade or abrasive tool. Machines are also used to smooth out the surface details for obkatyvaniya surface rollers. Metalworking machines perform cutting non-metallic materials such as wood, phenolic, nylon and other plastics. Special machines are treated as ceramics, glass and other materials.

Metal-working machines are classified according to various criteria, in Depending on the type of process used cutting tools and packaging. All commercially available machines are divided into nine groups, each group includes nine types. Machines of the same type may differ layout (eg, universal milling machines, horizontal, vertical), kinematics, ie a set of links that transmit motion, structure, governance, size, accuracy of processing and other Standards identified the key dimensions that characterize each type of machine. For lathes and circular machines, it is the largest diameter of the workpiece for milling machines – length and width of the table, on which set piece or equipment for cross-planer – the greatest stroke of the slide with the tool. Group of similar machines that have a similar layout, design and kinematics, but have different basic sizes, of size range. Thus, the standard for general-purpose gear hobbing machines provided with a diameter of 12 sizes of installed products from 80 mm to 12.5 m. The design of each size machine, designed for the given processing conditions, is called a model. Each model is assigned a code number – the number that consists of several letters and numbers.

Technology Drywall

Be careful when marking, to coincide with the holes in the concrete wall should be as accurate as possible. Apply glue on a sheet of drywall with a notched trowel. Of Technology, recommended to be on the perimeter, plus one – two lanes in the middle. But best of all leaf so will have more opportunities to balance it. Set the sheet to the wall on a lining (a couple of pieces of drywall the same should be fine), pull the wire ends through the holes. Do not press down list directly to the wall, first straighten. Drywall must align with the rules, applying it to the list, and where you can see that the plaster sticks – press down harder, and so on throughout the list.

Similarly, all other sheets kleite. When the glue hardens, the lining must be removed. How to handle drywall I have already described in the beginning of this section, no differences in general, no, except that the bevel to remove is not necessary, because the horizontal joints with a liner there, and on Vertical already have factory-thinning, it is enough. So go to the next method. Method of cladding number two. If the wall is less than equal, for example, not concrete, and brick, you have to align it with using a thicker layer of glue. In preparing the walls significantly different from the above methods do not, just under the wire to Stroebe, drilled under the sockets and switches, and naturally primed. But the glue on sheetrock should be applied, first, the other (as a rule – "Perlfiks"), and secondly, by other means.
