Dry Screw Vacuum Pump for Photovoltaic Industry

Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. The photovoltaic power generation industry chain from upstream to downstream mainly includes polysilicon, silicon wafers, solar cells and battery modules. 


Manufacturing processes from silicon crystal pulling to solar cell production to solar module stacking would not be possible without a vacuum pump.  



The lamination process of solar cells consists in encapsulating the solar cells while attaching the front and rear protection sheets. For best results, the pumping speed of screw vacuum pump is perfectly suited for this application.  


A thin film is a layer of material with a thickness ranging from nanometers to several micrometers. Thin film technology has improved over the past few decades and requires reliable products for the best quality.  


Dry Screw Vacuum Pump Features  

  1. There is no medium in the working chamber, and a clean vacuum can be obtained

  2. The surface of the working cavity and the screw rotor has anti-corrosion coating, which can adapt to harsh working conditions

  3. The gas is not compressed in the pump, which is suitable for extracting condensable gas

  4. A single screw vacuum pump can pump from the atmosphere to 1Pa, and the vacuum system can be greatly simplified

  5. The water temperature has little effect on the vacuum, saving more than 90% of water, and even no water consumption

  6. No fuel consumption, no dripping

  7. There is no friction between the rotating parts, it can run at high speed, and the whole pumpis small in size

  8. Simple structure and easy maintenance

  9. The pumped gas is directly discharged from the pump body, no water pollution, no environmental protection pressure, and gas recovery is more convenient

  10. It can be combined with roots vacuum pump and molecular pump to form an oil-free vacuum system
