New balancing process increases service life of turbopumps
Turbopumps play an important role in vacuum technology when pure high vacuum and ultra-high vacuum is to be generated . Inside the hybrid-bearing turbopump , a rotor is supported by a combination of permanent magnet bearings and roller bearings and driven at very high speeds . A new balancing process for hybrid-bearing rotors increases the service life of ball bearings by up to 20 percent , while reducing vibrations and lowering noise emissions .
