谁能帮我翻译下这段文字呢摘 要随着社会经济持续、高速发展，近年来我国能源的需求也出现较高的增长速度，热电联产已经进入大机组的发展阶段，300MW大型抽汽冷凝两用机组已逐渐投入运行，这些高参数大容量机组，在非采暖期与凝汽机组效率基本相同，在采暖期有明显的节能效益，因而在热电联产集中供热中发挥了巨大作用。而着眼于优化和完善热力系统及其设备，改善运行操作，提高运行效率，降低运行成本正在成为热电联产工作的一个重点。对热力系统进行局部定量分析和全面优化，以及技术改造，可以充分挖掘热力系统的节能潜力，为火电厂节能降耗开辟一个新的领域。本文主要阐述国产30万千瓦发电机组的锅炉给水泵的容量,台数与型式的选取，水泵组的配置方案，给水泵的扬程计算，机组启动或低负荷运行时,防止给水泵汽蚀的方法，除氧器定压运行,给水泵入口静压力的计算，给水泵组的布置。关键字：给水泵 扬程计算 防止汽蚀 压力计算辛苦啦，谢谢

With the continued socio-economic, high-speed development in recent years, China's energy needs also a higher growth rate, combined heat and power unit has entered the big stage of development, 300MW dual-use large-scale extraction condensing unit has been put into operation, these high - Parameters of large-capacity generating units, non-condensing steam heating unit with the same efficiency in the heating period of significant energy efficiency, which in combined heat and power central heating has played a huge role. The focus on optimizing and improving the heating system and its equipment, operating improving the operation and improve efficiency, reduce operating costs combined heat and power is becoming a major focus of the work. Heat on the local system of quantitative analysis and optimization of all-round, as well as technological transformation, you can tap the energy potential of the thermal system, saving energy for thermal power plant to open up a new field. This article on China-made 300,000 kilowatt generating units of the boiler feed pump capacity, the number and type selection, the configuration of the group pumps, water pumps to lift the calculation unit to start or low-load operation, to prevent pump cavitation way Deaerator pressure to run, the entrance to the pump static pressure calculations, the group pumps to the arrangement.
