The Influence and Improving Measures of Water Jet Condensation Vacuum Pump on Vacuum Drying System 水喷射真空冷凝泵对真空干燥系统的影响及提高措施
The high voltage variable frequency transformation of power plant's pump system of condensation water pump, condensation water booster pump is described briefly. 对发电厂的凝泵、凝升泵的高压变频改造进行了简要叙述,并对经济性试验的数据进行了定量分析。
Use of this device will flash steam condensation in the water being sucked out at the same time, reduce the temperature, and then anti-cavitation pump reuse. 采用这套装置可使凝结水在闪蒸汽被吸走的同时,温度降低,再用防汽蚀泵回收使用。
Modified Frequency Technology Retrofit to Condensation Water Pump of Home Produced 300 MW Direct Air Cooled Power Unit 国产300MW直接空冷机组凝结水泵变频改造
A set of high voltage converter can drive two motors. That means the condensation pump can switch between variable frequency and working frequency when failures come. 采用一拖二方案,即在故障发生时,凝结水泵在变频和工频之间进行切换。
In this study, based on the analysis of principles and characteristics of evaporative condensers, the feasibility of using evaporation condensation method for large air-cooled unit of small steam-driven feed water pump turbine were analyzed. 本文首先在分析蒸发式冷凝器原理及特点的基础上,对大型空冷机组汽动给水泵小汽机采用蒸发冷凝方式的可行性进行了分析。
