摘要
本文分析了居民区供水与一般工农业供水的不同点及保证供水效果的条件,并对西安市现有供水系统从理论到实际进行了多方面的分析,指出了存在的问题和改进方向,认为采用无级调节泵容量的方法对居民区供水可获得最佳节电效果;文中介绍了所研制的两种新型全自动无塔无罐型居民区供水系统,及水泵电气传动调速方案的选择。
Here a deep analysis of the separate features of the residential area water-supplying systems from the general industrial as well as agricultural water-supplying have been performed so as to gain more effective water-supplying results. A further extensive study has been made through the existing water-supplying systcms of Xian municipality theoretically and practically. The problems existed and the ways to bc improved have been given out. It is convinced that non-stage pump capacity can be used to provide water for the residential area in order to save electricity to its best advantage. The paper will introduce two types of new automatic water-supplying systems without tank or tower and current speed governing AC drive systems in the pump drive.
