Evacuation

Integrated or Separate Vacuum Plants

 

For evacuation of transformers or tank systems, double stage pump systems are either directly mounted on the base frame of the VOP oil purification units or designed as stand-allone plants, which can be operated independently

    For evaluation and design of the vacuum plants, various calculations are done:

  •  Calculation of the effective suction capacity of vacuum pumps at variable achievable end pressures (Pe)
  • Calculation of suction capacity curves in function of the achievable final vacuum
  •  Calculation of corresponding suction capacity curves in function of initial suction pressure
  •  Calcualtion of effective suction capacity of vacuum pumps in function of effective suction pressure and achievable final vacuum

For existing systems, the suction capacity curve of an unknown vacuum plant can be calculated and estimated. Additionaly, the suction capacity can be measured by our unique measuring device
