Energy-Conserving Vacuum Pump

Energy-Conserving Vacuum Pump china vacuum Pumps Installing a Variable Velocity 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 can be adapted to blower or in some instances rotary vane type vacuum pumps. They function by changing the rate of the vacuum pump based on the reading from a pressure sensor that’s installed on the vacuum line close to the receiver jar. The VSD is basically a dedicated computer with many adjustments so it may be possible to improve vacuum regulation over the normal pneumatic vacuum regulator that only 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 per day. Typically a VSD will never be a cost-effective option for small dairies due to less milking time and therefore shorter vacuum pump operate times but there are several other choices to save lots of energy costs.
