Photovoltaic industry, the application of dry screw vacuum pump type -

solar photovoltaic power generation system is a new type of power system, the use of solar photovoltaic (pv) effect of semiconductor materials to solar radiation energy into electrical energy directly, is a renewable resource. In recent years, photovoltaic power generation of green electric power development is the country encourages energy projects. The popularity of photovoltaic power generation of environmental protection has played a good role. According to the annual output 2224. The average of standard coal saving 20000 KWH calculation, at the age of 7398. 7 tons of carbon dioxide emissions of about 22353. 1 tons of sulfur dioxide emission reduction, 672. 6 tons of nitrogen oxide emissions, 336. 3 tons. Environmental benefits are very obvious. What is the relationship between photovoltaic generation and vacuum pump? Crystalline silicon is used to make pv cells, capture sunlight and convert it into energy, which is closely related to the development of vacuum technology. From silicon crystal drawn to solar cell production and solar module laminating, there can be no vacuum in the process of manufacturing. Whether you're focused on crystallization or thin film coating. Provide custom vacuum solutions of photovoltaic production is a key factor.

solar battery laminating process including encapsulation solar batteries, protective plate before and after protection plate connected at the same time. For best results, provides a very dry screw vacuum pump is suitable for the application of vacuum speed. The thickness of the membrane is range from nano material layer to a few microns. In the past few decades, membrane technology has been improved, need reliable products to achieve the best quality. For thin film deposition process, you can use the high performance of dry screw vacuum pump to provide first-class vacuum equipment to meet the requirements of this application.

import the performance characteristics of dry screw vacuum pump

1. Pumping gas directly from the pump body, do not pollute the water, no environmental pressure, gas recovery.

2。 Working chamber and the screw rotor surface have anticorrosive coating, can adapt to bad working environment.

3。 Water temperature will have little impact on the degree of vacuum, can save more than 90% of the water, not even water.

4。 A single pump can be from atmospheric pressure pump to 1 pa, vacuum system can be greatly simplified.

5。 Studio without medium, can get a clean vacuum.

6。 Don't be compressed in the pump, gas is suitable for extraction of condensable gas.

7。 There is no friction between rotating parts, high speed, small size

8. With roots pump and molecular pump oil free device used in combination.

9。 Simple structure, convenient maintenance.

10。 No fuel, dripping water.
