Energy-Conserving Vacuum Pump

Vacuum Pumps The installation of a Variable Quickness Drive (VSD), sometimes called a variable frequency drive, usually saves between 50 and 65% in electricity costs with the same or better regulation of vacuum. The range of energy savings can be from 30 to 80 percent. They may be adapted to Energy-Conserving Vacuum Pump blower or in some cases rotary vane type vacuum pumps. They work by changing the velocity of the vacuum pump based on the reading from a pressure sensor that’s installed on the vacuum collection near the receiver jar. The VSD is actually a dedicated computer with many adjustments so it might be possible to improve vacuum regulation over the typical pneumatic vacuum regulator that just includes a vacuum level adjustment. A VSD for vacuum pressure pump is usually economical for a dairy that milks a complete of 8 hours or even more per day. Typically a VSD will not be a cost-effective option for little dairies due to less milking period and therefore shorter vacuum pump operate times but there are some other choices to save energy costs.
