Leybold launches two vacuum calculation and simulation tools


2020-01-13

Vacuum technology specialist, Leybold, has developed two new online tools to assist customer’s pump choice and layout of complete vacuum systems: The Pump Finder and the calculation tool LEYCALC. With these new web-based tools, users can select and build their vacuum solutions online. They are designed to be used for two different use cases: The homepage leads to both the Pump Finder and LEYCALC, the vacuum system calculation tool. Users with vacuum know-how can use LEYCALC to calculate the behavior and performance of vacuum systems in detail. The Pump Finder guides even beginners to suitable products by a questionnaire.
The Pump Finder is designed to navigate vacuum users step-by-step to find the ideal pump for their application. Throughout the selection tool, pumps can be refined by entering values for chamber size, target pressure and pipe dimensions. There are two calculation options for modelling different vacuum applications: process flow and vacuum chamber pump down. A process gas flow is a continuous gas flow where the constant pressure is conveyed. A vacuum chamber pump down is an application where the chamber is pumped/evacuated to a specific target pressure. The result is a selection of vacuum pumps that meet the customer's requirements.
LEYCALC can be used for detailed engineering of vacuum systems using the same powerful algorithms as Leybold’s application experts. The tool allows customers to calculate their vacuum systems fully independently and for complex scenarios, the experts offer their full support. Now users can perform their calculations independently – with the result that the entire process leads to a more targeted and faster selection of the right solutions for the application. 
Once the user of the online tool has defined the pump’s chamber and the target pressure, LEYCALC performs the calculation of a pump down curve: The result is immediately displayed in a diagram. This shows exactly how long it takes to pump the air out of the chamber to a defined pressure and how the pressure develops over time. Alternatively, the user can calculate the pumping speed curve of a pump system. This shows which pumping speed is provided at a certain pressure. All calculation data is stored centrally and can be called up at any time and from any device by customers who have registered. Calculation results can also be shared with specialists at Leybold. This allows a detailed discussion about the respective vacuum application. 
Navigation through the web-based software solution is conveniently possible on all kind of devices like tablets, smartphones. Sections in need of explanation are linked to more detailed background information on vacuum technique. In future, LEYCALC will comprise the whole Leybold product portfolio, covering also high vacuum applications, the company said.
