Structurally, electronic scales car can be roughly divided into two groups: stationary and mobile. Mobile scales consist of sets of individual platforms and the electronic terminal. Generally used for measuring the weight of the car in parts. May be bed-and Mortice. Stationary Truck scales operate in a mode of long-term maintenance.
They can be besfundamentnye and foundation, the scale road to measure the mass the car completely and truck scales for measuring weight poosevogo. When poosnom (pomostovom) weighing vehicles by the summation of the weighing results of each element. Weighbridges are of one or more modules connected to each other. The modular design of weighing platform for easy installation of weights and promotes long-term safe operation. Different sizes of load modules allow you to create single-and multi-platform Truck scales meet the requirements for weighing various cars.
On balance, having platform lengths from 2.5 to 6 m, car weighed in two steps, and the total weight of the machine is computed as the sum of the weighing results all the car axles. For dynamic weighing weighing platform must be built into the foundation- priyamoy at the same level with the road. For such a foundation is required to design drainage systems. One should also consider the location of strain gauges (sensors) for the convenience of future Operating truck scales, as falling in the weights inside the debris and sediment carried in motor vehicles, will inevitably lead to the need for seasonal prophylaxis of stationary truck scales. Uniform for all Truck scales are the requirements for entrance. Platform for mounting the weights must have a straight section of road way, segments of the path before and after the weights have to be on the same level. Mounting location of dynamic Truck scales characterized by high demands. This linear portion of the way without turning, without deviations.
A professional designer exaction color for web pages – a creative process. Basic tools of professional web designer – experience and intuition. It's nice to have and the experience and intuition. Worse, when there is no experience, and web page needs to be done. Let's try a little look into the matter – the selection of colors for the WEB page. For a start – a theory. So: Primary (primary) colors are red, yellow and blue – this is common knowledge. Secondary (secondary) colors prepared by mixing one color with another.
If you mix yellow and red – get orange, mix red and blue – get magenta (purple), mix blue and yellow – get green. There is such a thing tertiary (tetriary) color. To get tertiary colors is taken primary color and adds a secondary, those that are in the neighborhood. From this it turns out – in two colors of each primary color – six tertiary colors. For the concept of interaction these flowers – they have a circle. WEB designers call it the color wheel and is used for color selection for WEB sites.
So how to use the color wheel? In theory – very simple. Put a point on the circle on the spot selected you color. Colors corresponding to the selected primary will be located at an equal distance from the ground. That is, if you're in trouble with the geometry, then connecting these points, get an equilateral triangle. By turning to axis – consistent colors are selected. And so, as they are always in threes, then this method of selection of colors is called triadic scheme. But it's not all. You can and should pick colors arranged in a circle facing each other, so-called complementary colors. Why are they called? Bred near, they complement each other, they are complimentary to each other. Now for the more complex combinations of colors WEB. You can choose two pairs of complementary colors. Well, for example, we have a yellow and purple, they can take the blue and orange. This arrangement is called a double compliment. Take a triad of colors and color, complementary to one of the color triad. This scheme is called an alternative compliment. Take a color complementary to this color and the two adjacent colors. This arrangement is called a split compliment. And, so-called tetrad. This is when they choose four colors on the color wheel are located opposite each other. It was a combination of contrasting colors. But there are two schemes using related colors. This is a monochromatic scheme. That is, taking one color and its shades are used. Not a bad way, an option. And the scheme called homologous. In this scheme, selected colors are next on the color wheel. That such a system. True, if only it were that simple, then the designer would be one. In practice all the harder. Even if you do it on system – there is no guarantee that everything will be perfect.
Given the great diversity of plants, a wide price range of diesel-and gasoline generator on the market, their different purpose – to decide to buy power from its appointment – backup or main, location (room or street), the need for fixed or mobile stations (diesel generator, gasoline generator), the availability of power at startup failure of centralized power. 1. The choice of power plants (diesel generator, gasoline generator). To determine how nominal and maximum power must have your power plant (diesel generator, gasoline generator), it is necessary to determine the total capacity of electric power consumers, which will or may be operated simultaneously. First of all, it is necessary to define devices that you want to connect: active (electric cookers, lighting, heaters, etc.), inductive (drills, saws, pumps, compressors, refrigerators, electric motors, laser printers, etc.) If you have chosen power (Diesel generator, gasoline generator) with a synchronous generator, its power is calculated from the following relations: for the active power is necessary to sum all of simultaneously connected devices, add approximately 15-20 – percent power reserve, and you have the necessary power plant (diesel generator, gasoline generator). Elect an inductive type needs at the time of starting for more power, so the total power need to increase by 2.5-3 times to ensure efficiency power plants (diesel generator, gasoline generator). Practical experience of using plants suggests that the work of two – three light bulbs refrigerator, TV on your summer cottage is enough power to 2 kilowatts. The owner of a country cottage, which is constantly worried about shortages of electricity, you must purchase power (diesel generator, gasoline generator) with a capacity of 10 to 20 kilowatts.
