Energy-Conserving Vacuum Pump

Vacuum Pumps The Energy-Conserving Vacuum Pump installation of a Variable Velocity Drive (VSD), sometimes called a variable frequency drive, usually saves between 50 and 65% in electrical power costs with the same or better regulation of vacuum. The number of energy savings could be from 30 to 80 percent. They could be adapted to blower or in some cases rotary vane type vacuum pumps. They work by changing the acceleration of the vacuum pump based on the reading from a pressure sensor that is mounted on the vacuum collection near the receiver jar. The VSD is basically a dedicated pc with many adjustments therefore it might be possible to boost vacuum regulation over the normal pneumatic vacuum regulator that only includes a vacuum level adjustment. A VSD for a vacuum pump is usually cost-effective for a dairy that milks a total of 8 hours or even more per day. Typically a VSD will not be an economical option for little dairies due to less milking period and thus shorter vacuum pump operate times but there are several other choices to save lots of energy costs.
