The application of dry screw vacuum pump _ photovoltaic industry

photovoltaic (pv) is the abbreviation of solar pv systems. It is a new type of power generation system, solar energy battery photoelectric effect of semiconductor materials to convert solar radiation directly into electricity. It is a renewable resource.

in recent years, photovoltaic power generation is the state encourages the green electric power development projects. The popularity of photovoltaic (pv) has played a very good role in environmental protection. According to the annual output 22. 24 million KWH calculation, save $7398 per year. 7 tons of standard coal, reduce carbon dioxide emissions by about 22353. 1 ton, reduce sulfur dioxide emissions by 672. 6 tons, reduce nitrogen oxide emissions by 336. 3 tons, the environmental benefit is very obvious.

crystalline silicon, CdTe, CIGS or silicon thin-film technology of various capture sunlight and convert it to energy for the production of photovoltaic cells, which is closely connected with the development of vacuum technology. From the crystal pulling silicon to solar cell production, laminated to the solar cell components, impossible that there is no vacuum in the manufacturing process. Both focus on the crystallization and thin-film coating, it doesn't matter, to provide tailor-made vacuum solutions is the key factor in pv production.

solar battery protection board before and after laminating process including the connection of packaging solar cells at the same time. For best results, dry screw vacuum pump can provide vacuum pumping speed, is the ideal choice for this application.

the membrane is a layer of material, the thickness range from nanometers to a few microns. In the past few decades, membrane technology has been improved, reliable product is needed to achieve the best quality. For thin film deposition process, can be used to provide high performance of dry screw vacuum pump vacuum equipment, to meet the requirements of the application.

1, there is no medium in studio to produce clean vacuum.

2, studio, and the surface of the screw rotor are coated with anticorrosive coating, to adapt to bad working environment.

3, gas no compression in the screw vacuum pump, suitable for extraction of condensable gases.

4, can be a single screw vacuum pump from atmospheric pressure to 1 pa, and can greatly simplify the vacuum system.

5 almost has no effect on the vacuum, water temperature, even there is no water can save more than 90% of the water.

6, no fuel consumption, no drop.

7, there is no friction between rotating parts, high-speed operation, small size

8, simple structure, easy to maintain.

9, pumping the gas pump body directly from the screw vacuum pump discharge, polluting the water, there is no pressure environment, easier to recycle gas.

10, roots pump and molecular pump has no oil equipment used in combination.
