Откачные станции CombiLine

Pumping stations are a combination of several pumps and, depending on the task and the required performance, can consist of:

Roots pumps

Rotary vane pumps

Turbopumps

Cryopumps

Diffusion pumps

Vacuum meters

Analytical equipment

Pumping station control systems

Modern production technologies require enormous pumping speeds. Just imagine that you need to evacuate a volume of 630 cubic meters. This is equivalent to the volume of a small house. Today, systems with cameras of this size are used for electron beam welding of parts weighing up to 50 tons and dimensions up to 6 · 12 · 5 meters. An electron beam power of 40 kW allows to reach a depth of weldability of up to 100 millimeters in steel and up to 150 millimeters in aluminum. This requires a vacuum of 5 · 10E-4 mbar. In addition, high pumping speeds allow for increased work efficiency.
