变频节能设计实验的实践探索

Practical Exploration on Design Experiment of Frequency Conversion and Energy Saving

在化工原理实验课程中,流体流动综合实验包含了离心泵曲线的测定、流量计的标定等实验项目.通过最新变频技术开展了离心泵流量的测定与频率的关系的实验,有效弥补了目前教材中缺乏有关变频节能内容的不足,具有很高的创新性,对于提高学生主动学习能力具有重要的意义,培养了学生的工程素质,提高了他们的综合能力.

In chemical engineering principle experiment, fluid flow comprehensive experbment includes the determination of centrifugal pump characteristic curve, calibration of flowme-ter, etc. The experiment of relation between flow rate and power frequency was developed by lat-est technology of frequency conversion to make up the deficiency of frequency conversion and en-ergy saving in current textbook, which can improve students＂ active learning ability, cultivatestudents＂ engineering quality and develop their comprehensive competences.
