为了贯彻石化部油开组77年12月在胜利油田召开的全国注水输油泵会议精神,达到提高注水泵效率、节约用电、提高工人技术水平及企业管理水平的目的,必须使更多的同志掌握用热平衡原理来测量注水泵性能的方法。此法测试简单,只用压力表和温度计即可测出水泵效率,而且比一般方法要准确。另一个特点是,在没有流量计的情况下,测出水泵轴功率后,可计算出水泵的排量。本文主要介绍公式来源及误差分析。
In order to carry out the spirit of the National Water Pump meeting held by the Ministry of Petrochemical Industry in December 77, Shengli Oilfield to achieve the purpose of improving water pump efficiency, saving electricity, improving worker’s technical level and enterprise management level, more comrades Master the principle of heat balance to measure the performance of water injection pumps. This method test is simple, only the pressure gauge and thermometer to measure the pump efficiency, and more accurate than the average method. Another feature is that in the absence of flowmeter case, measured the pump shaft power, you can calculate the pump displacement. This article mainly introduces the formula source and error analysis.
