Dry screw vacuum pump _ in the photovoltaic industry

today is to introduce, the application of dry screw vacuum pump in the photovoltaic industry, photovoltaic industry may we contact less, photovoltaic (pv) is the abbreviation of solar photovoltaic power generation systems. It is a new type of power system, the use of solar photovoltaic (pv) effect of semiconductor materials to convert solar radiation directly into electricity. From upstream to downstream of the photovoltaic industry chain including polysilicon, silicon chips, batteries and battery components such as industrial chain. For the photovoltaic industry to provide professional vacuum solutions, dry screw vacuum pump in the application of photovoltaic industry.

with the increase of solar panels production, the production area is becoming more and more important. For the market to provide high-quality products and excellent dry screw vacuum pump vacuum solutions.

such as crystalline silicon, CdTe, various process of CIGS or silicon thin film technology, capture sunlight and convert it into energy for the production of photovoltaic cells, is closely connected with the development of vacuum technology. From silicon crystal draw to solar cell production, to solar module laminating, impossible that there is no vacuum in the manufacturing process. It does not matter whether focus on crystallization or thin-film coating, provide tailor-made vacuum solution is a key factor in pv production.

laminated - Solar battery laminating process including the connection protection plate before and after protection plate encapsulated solar cells at the same time. In order to obtain the best effect, provide the vacuum dry screw vacuum pump suction speed, very suitable for this application.

is the membrane thickness ranging from nano material layer 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, the high performance of dry screw vacuum pump can be used to provide the same kind the best vacuum equipment, to meet the requirements of the application.

import the performance characteristics of dry screw vacuum pump

1. No media in the working chamber can get the vacuum cleaner.

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

3, not in pump gas compression, suitable for extracting condensable gases.

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

5。 The water temperature of vacuum have little impact, saving more than 90% of the water, not even water.

6, no fuel consumption, no drop of water.

7。 No friction between rotating parts, high speed, small size

8, simple structure, convenient maintenance.

9, pumping gas directly from the pump body, do not pollute the water, the environmental pressure, more convenient to recycle gas.

10, and the roots pump, molecular pump oil free device combination.

the advantages of the dry screw vacuum pump

1. Optimization of processing by-products from laminating process.

2。 Running time is long, low maintenance cost.

3。 High steam resistance and compatibility particles.

4。 Easy to clean.

5。 Dry screw vacuum pump operation cost is low.

6。 Minimum maintenance and prolong the maintenance intervals.

as long as China pv enterprises manufacturing level has improved, as long as China pv enterprises while maintaining the cost advantage to increase technology advantage, as long as China pv enterprises to face the development of photovoltaic, pv enterprises can best serve the economic production and people's. Although dry screw vacuum pump application in the photovoltaic industry is valid, but we still need to continue efforts to contribute to the photovoltaic industry.
