节约能源是我国国民经济建设的一项重要原则。特别是在工业城市密集的地带,能源更趋紧张,每一项用电工程都必须尽量考虑各种节能措施。如辽宁省营口地区大辽河泵站群,就应精打细算以降低能源单耗。但该地区在感潮河段上的许多泵站、由于规划时采用不适宜地确定外河设计下水位的方法,经复核验算,仅泵站一项就造成能源浪费近 Saving energy is an important principle in our country’s national economic construction. Especially in densely populated industrial cities, energy is even more tense. Every electricity-saving project must consider various energy conservation measures as far as possible. Such as Liaoning Liaohe Yingkou Liaohe pumping station group, it should be carefully calculated to reduce energy consumption. However, many pumping stations in the tidal reach in the area are subject to review and calculation as a result of unfavorable methods of determining the water level of the river design during planning. As a result, only one pump station causes energy waste
