According to foreign media reports, a recent research team from Osaka University in Japan has developed the world's most powerful new laser, which belongs to the second-class Petawa pulsed laser with an energy of up to 2,000 megawatts. If you don't have a concept for 2000 trillion, then we can tell you in a more intuitive way, that is 2000000000000000 watts! However, this super-energy pulsed laser lasted only about one trillionth of a second (1000000 millionth of a second).
The laser was named LFEX (laser fast ignition test) and reached a length of 300 feet. Interestingly, although the LFEX laser has a particularly large amount of energy, it doesn't require any special effort to make it.
If you remember the physics knowledge of high school, you know that electric energy (watt) is an energy, and because the team at Osaka University keeps this laser for a short time, it takes only a few hundred joules to achieve such amazing power. energy of. The researchers used a series of lenses to continuously magnify the original laser through a series of lenses, and finally formed this super new laser.
"The world is very competitive for improving the performance of lasers, and our ultimate goal is to be able to output 10 megawatts of laser power," said Junju Kawanaka, an associate professor at the School of Electrical Engineering at Osaka University, in a statement. This new type of laser has indeed left a very deep impression on us, and it is also of great significance as a scientific project. As for how to use it in the future, it remains to be studied.
The drag chain is normally used for the working conditions where reciprocating movement is required. It can be used to haul the internally-installed electric cables, oil pipes, gas pipes and water lines and protect them from damaging.
The drag chain has been widely used in the digitally controlled machine tools, electronic equipment, lifting and transport devices, manipulators and automatic warehousing.
There are some considerations for selecting Drag Chain :
1. Quantity, weight and dimensions of the electric wires and flexible hoses.
2. Travel distance
3. Limitations such as height and width for the installation
4. Method of assembly and the fixed direction
5. Travel speed
6. Working environment
According to the needs of different customers, we have five kinds of material of drag chain,Steel Cable Drag Chain, aluminum Steel Cable Drag Chain, Plastic Cable Drag Chain, stainless steel cable drag chain, Nylon Cable Drag Chain.
There are three common types of drag chain:
1. Bridge type drag chain. Each link of a chain can be opened, which facilitates the installation and maintenance operations. When the chain is operation, the following features can be obtained such as low level noise, friction resisting and high speed traveling.
2. Semi-closed type drag chain.
3. Total Enclose type drag chain. The totally enclosed type drag chains are the best choice for woodworking machineries and for those locations where it is dusty.
Product of good quality is the main reason why our products sell like hot cakes. Our products passed strict quality inspection. The quality of the drag chain is very reliable.
If you have any questions, please contact with us directly, and welcome to visit our factory. As long as you give us the blueprint, we can provide you with products of various sizes.
