What Is Vacuum Evaporation?
Vacuum Evaporation is a Physical Vapor Deposition (PVD) method used to create thin films on wafers and other substrates. The process uses a vacuum environment to evaporate a source material, after which the resulting atoms or molecules travel through the vacuum and condense onto the substrate surface. With precise control over film thickness and thin-film […]
Can a Vacuum Pump Oil Mist Filter Explode?
In oil-lubricated vacuum pump systems, the oil mist filter plays an important role in capturing oil mist, reducing oil emissions into the working environment, and supporting stable pump operation. However, if the vacuum pump oil mist filter becomes clogged and the pump continues to operate, exhaust-side pressure can increase significantly, potentially causing the filter to […]
Costly Repairs: What Happens If You Neglect Dry Vacuum Pump Overhaul?
Dry vacuum pumps play a critical role in various industrial production systems, helping create and maintain a stable vacuum environment. Notably, dry pumps do not use oil within the pumping chamber. However, this does not mean the equipment requires no maintenance. After a long period of operation, internal components are still subject to wear and […]
When a PLC Does More Than “Turn a Pump On and Off”: A Useful Vacuum Pump Jam Detection Function
In an industrial vacuum system, a PLC typically handles familiar control functions such as starting and stopping a vacuum pump, controlling valves, and receiving signals from sensors. But if a PLC is used only to “turn the pump on and off,” is the system really protected against abnormal conditions? With a properly designed PLC program, […]
[Case Study] ULVAC Vietnam Resolves ULVAC GLD-N280 Vacuum Pump Motor Burnout and Pump Seizure
