关于企业中能量平衡的测试方法问题,虽然已有不少文章和资料进行了介绍,但由于生产中的实际情况不同和目前一些测试手段的限制,测试仍存在一定困难。本文从流体力学、工程热力学的一些基本原理出发,系统地总结了水泵、风机、电动机、电力拖动装置及空气压缩机的测试和计算方法,对测试中的一些难以测量的量,也给出了一些切实可行的测试和计算方法。 Although there are a lot of articles and materials on the test of energy balance in enterprises, there are still some difficulties in testing because of the different actual conditions in production and the limitations of some current testing methods. Based on some basic principles of fluid mechanics and engineering thermodynamics, this paper systematically summarizes the testing and calculating methods of pumps, fans, motors, power drafts and air compressors, and gives some hard-to-measure quantities in the test Some practical testing and calculation methods.
