前言 冶金工业用水量大,配备各类水泵多,它们的耗电量在企业总耗电量中所占比重很大。以我们公司为例,每日需供水约280万米~3,装有水泵550多台,配套电机总容量17.8万瓩,日耗电近100万度,占公司总耗电量六分之一。由于在冶金企业生产过程中,绝对不容许中断供水,水泵用电列入必保户,因此,尽管水泵电能利用率很低,也未为人 Preface Metallurgical industry with large amount of water, equipped with various types of pumps, their power consumption in the enterprise a large share of the total power consumption. Take our company as an example, daily water supply is about 2.8 million meters ~ 3, equipped with more than 550 pumps, supporting a total capacity of 178,000 瓩 motor, daily consumption of nearly 1 million degrees, accounting for one-sixth of the company’s total power consumption . As in the metallurgical production process, absolutely not allow interruption of water supply, water pump electricity included in the guaranteed, therefore, despite the pump is very low utilization of electricity, nor human
