Energy-Conserving Vacuum Pump

Vacuum Pumps Installing a Variable Rate Drive (VSD), sometimes called a Energy-Conserving Vacuum Pump china adjustable 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 instances rotary vane type vacuum pumps. They function by changing the velocity of the vacuum pump based on the reading from a pressure sensor that is mounted on the vacuum line near the receiver jar. The VSD is actually a dedicated pc with many adjustments so it may be possible to improve vacuum regulation over the normal pneumatic vacuum regulator that just has a vacuum level adjustment. A VSD for a vacuum pump is usually economical for a dairy that milks a total of 8 hours or even more each day. Typically a VSD will not be an economical option for little dairies because of less milking period and thus shorter vacuum pump operate times but there are several other choices to save energy costs.
