Portable Solar Collector

Thursday, April 13th, 2017

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. 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. Details can be found by clicking William R. Nuti or emailing the administrator.

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. 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.

Flange Bolt soedinenie.Raschet soedineniya.Bolt (from the German. Bolt), fastener, usually a rod with a 6-sided or square-head screw for screwing the nuts. In terms of machine parts more general concept fastener is a screw. Loosen the screws, depending on the type of threaded connection is used the following versions: 1) the screws and nuts, commonly called bolts; 2) screws, screw-fastened to one of the parts. Bolts used: a) to bond parts are not very thick, plates, flanges, bars in the presence of space for the location of the bolt head and nut, and b) to bond the parts from materials that do not provide sufficient reliability and durability of the thread, and c) when the need for frequent screwing and unscrewing.

In bolts, screws, studs used metric thread, which is the main thread and has a triangular profile angle at the vertex 600. Metric threads are divided into large and small steps. Profiles of geometrically similar. Adopted for the main thread with a big step. The static load carrying capacity of this thread above and less effect on strength protovleniya errors and wear than fine pitch thread. Endurance limit of high-strength steel screws decreases with decreasing pitch, and screws (bolts) of low-carbon steels increases. The technical background literature, standardized and most widely fasteners with the name 'BOLT' regardless of whether they will be fastened with a nut or screwed into the part. The shape of the head bolts (screws) are divided to: a) capture tool outside the head (hexagon or square), b) Chisels inside and from the end of the head (with Allen), and c) prevent the crank (with protrusions, is laid in nests or with two parallel edges, is laid in the grooves).
