The photovoltaic power generation industry has dual requirements for production continuity and vacuum cleanliness. Traditional oil-lubricated vacuum pumps generate oil mist during operation, posing a risk of contaminating cells, modules, and coating chambers. They also require regular oil changes and maintenance, affecting continuous production. Leynow oil-free vacuum pumps adopt an oil-free lubrication structure to prevent oil contamination from entering the vacuum system from the source, and have become the preferred configuration for multiple processes such as photovoltaic module lamination, cell coating, silicon wafer processing, photovoltaic glass coating, and vacuum adsorption handling.
Challenges Faced by the Industry
The requirements of photovoltaic production for vacuum systems are not just about "pulling a vacuum", but more importantly, cleanliness, stability, resistance to continuous operation, and high ultimate vacuum. In practical applications, customers often encounter the following types of problems:
Risk of Oil Contamination
Oil-lubricated vacuum pumps generate oil mist during exhaust, which may contaminate cells, modules, and coating chambers, affecting photoelectric conversion efficiency and module yield.
Pumping Speed Cannot Keep Up with the Cycle
Processes such as lamination and coating have fast cycles. Insufficient pumping speed of the vacuum pump will prolong the production cycle and affect overall capacity and film quality.
Unstable Continuous Operation
Photovoltaic production lines often require 24-hour continuous operation. Pump body overheating or vacuum fluctuations will directly affect module lamination quality and cell coating uniformity.
High Maintenance Costs
Vacuum pump oil needs to be replaced regularly. Under working conditions containing silicon powder and coating by-products, the oil is prone to deterioration, and downtime for maintenance affects overall production efficiency.
Leynow Photovoltaic Power Generation Industry Solutions
Targeting the actual working conditions of the photovoltaic industry, Leynow provides overall vacuum solutions centered on oil-free vacuum pumps, forming a complete service closed loop from equipment selection and installation and commissioning to post-maintenance.
Clean and Oil-free Vacuum Acquisition Method
Oil-free vacuum pumps adopt a self-lubricating structure, and the inner wall of the cylinder is specially treated. They do not generate oil mist or exhaust gas, preventing lubricating oil from entering the vacuum system, meeting the high cleanliness requirements of photovoltaic cells, modules, and coating chambers.
Selection Solutions Matched to Photovoltaic Processes
Based on the laminator model, coating equipment chamber volume, ultimate vacuum requirements, and production cycle, professional engineers provide selection suggestions to avoid efficiency and lifespan issues caused by "using a large pump for a small job" or "overloading a small pump".
Guarantee of Stable and Continuous Operation
For photovoltaic production lines operating continuously for 24 hours, the heat dissipation and anti-corrosion structures are optimized to reduce the risks of pump body overheating and by-product deposition, maintain stable vacuum degree output, and ensure module lamination and cell coating quality.
Full-cycle Service and Parts Guarantee
Providing installation and commissioning, regular follow-up visits, and maintenance contract services. Repair parts are Leynow original genuine parts. All repair projects come with a 12-month warranty to reduce unplanned downtime.
