Hardware Knowledge: Aluminum quality, determined by four factors.
1. Alloying elements

6063 alloy is Mg-Si alloys prepared for the main elements, each element have a range of content, the high cost of magnesium. Some manufacturers in order to reduce costs, the magnesium content with less to a minimum allowed. Some Even worse, the magnesium content of less than the minimum level allowed. There are factories in Canada in the alloy wire scrap and waste basin waste aluminum pan and basically not to mention 6063 alloy. Resulted in very low mechanical strength aluminum, can be as low to the corner to be easily bent with the hands, commonly known as soft as noodles. That is why aluminum can be one of the reasons a few thousand dollars cheaper.

Regular aluminum manufacturers in the preparation of alloy composition, the internal standards are, that is, within the framework of a variety of element content, the plants have their own smaller range, aluminum, magnesium, silicon ratio requirement among the very strict The factory has its own data and confidentiality of each other. Qualified formulations made of alloy, in order to ensure the quality of this, or how the processing, quality can not go up.

Technology management is the production of small hydropower plants all the technical activities of scientific management and strict organization, so that science and technology into productive forces, thereby enhancing economic efficiency. Improve the efficiency of protection is safe and secure core is the management of the result is effective. The technical management is a set of knowledge, intelligence, and technology-intensive profession, in our country, reconstruction is very conspicuous phenomenon of light-pipe in the project construction period is composed of a large number of departments from the governing body to operate, once the project put into operation will have no who is interested. Operation and management unit, the implementation of enterprise management, first, an extensive in-house production management, lack of incentives, and second, the traditional employment system is too inclusive, resulting in a low educational level business personnel, technical quality of the poor, the majority of workers affected by the end of formal training, the lack of should be Some of the knowledge. With the reform, social progress and scientific and technological development, all kinds of advanced technology and equipment widely used in small hydropower plants on the technical management of the operation has become increasingly dependent and demanding higher and higher. How to strengthen the technical management, improve the economic efficiency of enterprises, I believe that the technical management of a small hydropower plant in the following areas can be strengthened.

Diesel engine exhaust black smoke from diesel combustion is not sufficient, at high temperatures with the decomposition of a carbonaceous gas emissions phenomenon. Exhaust black smoke, not only reduces the engine power, an increase of diesel oil consumption, and easy to form coke and shorten engine life. The following reasons:

First, lack of fresh air in the cylinder

Reasons: (1) air cleaner filter dust too; (2) mufflers rust, coke or oil. (3) The intake and exhaust valve clearance is too large, so reducing the valve opening; (4) Orchestration body parts loosening, wear, deformation, camshaft gear and crankshaft timing gear changes in the relative position, valve opening and closing time is not correct.

The principle of wind power is the use of wind-driven windmill blades rotate, and then through the growth machine will increase the speed of rotation, to encourage generators. According to the current windmill technology, is about three meters per second, the speed of the breeze (the breeze of the level), they can begin to generate electricity.

Wind power is in the world to form a craze for wind power without fuel problems, it does not produce radiation or air pollution.

Wind power generation in Finland, Denmark and other countries are popular; the western region of China is also strongly advocated. Small-scale wind power generation system very efficient, but it is not only composed by a generator head, but a certain scientific and technological content of the small systems: wind turbine + Charger + digital inverter. Wind turbines by the nose, swivel, tail, leaf form. Each part is very important for all of some functions as follows: leaves used to receive through the nose into the wind power; tail so that leaves always opposite to the direction of the wind to get the most out of the wind energy; swivel head allows the flexibility to rotate in order to achieve tail reorientation functions; nose of the rotor is a permanent body, the stator windings cutting magnetic field lines to generate electricity. read more »
