采用感应线圈测量电潜泵机组转速的新方法

现有的电潜泵机组没有外露的旋转部件 ,只能用振动法测量潜油电动机的转速 ,误差大 ,而在做整机试验时系统是密封的 ,机组平衡较好 ,用振动法无法测试。为此 ,提出了采用感应线圈测量电潜泵机组转速的新方法 ,研究了测速系统的工作原理、基本组成及标定方法。新型测试系统的转速测量精度为± 0 1%;转速测量范围为 2 70 0～ 35 0 0r/min。经过几次对比试验 ,采用新型测试系统测量电潜泵机组转速的精度可达± 0 1%,最差不超过± 0 2 %。

Adopting induction coil to measure rotary speed of power package of Esp

In the light of the disadvantages of measuring rotary speed of power package of ESP with the vibration method, a new measuring method using the induction coil is put forward. The working principle, basic components and calibrating method of the speed measuring system is described. The measuring accuracy of the new system is ±0.1%, and the measuring range is 2 700～3 500r/min.
