Analysis of Energy-saving Effect of Fan and Pump with Differential Speed Regulation Equipment
As fan and pump speed regulation operation has huge energy-saving potential,this paper discusses the working principle of three types of differential speed regulation equipment including hydraulic coupling governor,eddy current permanent magnet governor and winding permanent magnet governor,analyzes the power loss of the three types of differential speed regulation equipment in the operation of the fan and pump speed regulation,and compares the energy saving data and energy saving effect of different fan and pump applications under the same speed regulation conditions.
