Maintenance of sf6 vacuum Zero emission

Maintenance of sf6 vacuum Zero emission

Epiroc has worked with ABB to develop the e-drivetrain for Railcare's battery-powered vehicle for rail maintenance applications. The multi-purpose vehicle offers emission-free, low noise operation that improves the working environment and increases its potential for deployment underground, such as in metro systems and mines.

    4/20/2012 4. Achieving zero emissions: Calculate (cont’d) Use the following formula to determine the number of pounds (mass) of SF6 within a given volume: Volume( ft 3 ) ÷ density= lbs. For example: 80PSIG @ 80°F = 0.38 density. For a volume of 200 ft3: 200 ft 3ft 3 ÷ 038 5263lb0.38 = 526.3 lbs.
