阀门开度 meaning in English
valve opening
Examples
- Through adjustment of the thermal control parameters , the valve stem leakage problem of the main steam valve resulted from insufficient opening in hot state has been eliminated
通过调整热控参数，消除了热态时阀门开度不足问题，主汽门杆再未发生蒸汽泄漏。 - In the water works control aspect , modifying the valve by the effective algorithm can lighten the pipe ' s pressure in order to resolve the water hammer defensive problem
在水利控制方面，针对工程中需要重点解决的水锤防护问题，采取有效的控制算法，通过控制阀门开度来调节管道流量，达到减轻管道承受的压力的目的。 - Best test regions are confirmed to found the acoustic emission test method for valve leakage . the large amount of data collected also allowed a brief investigation of the effects of different opening , valve types , differential pressure and leakage rates
根据本次研究工作的目的和特点并结合现场的实际情况，探讨了内漏时阀门开度、阀门类型、两侧压差以及泄漏率等因素变化时的声学特性。 - After retrofitting the digital electro - hydraulic ( deh ) control system of the steam turbine unit no . 1 in dezhou power plant , the valve stem leakage has occurred on the highpressure main steam valve , and the causes leading to the said leakage being analysed
摘要对德州电厂1号汽轮机组在经过deh控制系统改造后高压主汽门杆发生蒸汽泄漏的原因进行了分析，认为蒸汽泄漏是热态时阀门开度不足所致。 - Based on advanced technology , this thesis bring forward the optimal scheme and set down general system - drawings and flow charts . using step7 - micro software , we achieve the auto - control aim in drinking water treatment . in practice , the complexity and non - linaerity exit in the system of water treatment , so we apply fuzzy control in water treatment and design a kind of controller which structure can be altered according to the using - rate of ozone and the variety of water quality
实际饮用水处理系统由于存在复杂性、非线性、时变性，本文根据臭氧生物活性炭水处理工艺存在复杂性、非线性、时变性等特点，将模糊控制应用在水处理这一不确定的非线性时变系统，针对不同水温下臭氧利用率及水质的变化，设计一种基于系统过程状态的变结构的模糊控制器，以单片机作为主要控制硬件，按查表方式设计软件，对进水阀门开度进行在线控制，调节臭氧气体与进水的比例(臭氧流量及浓度不变) ，达到气水比最优化。
