振线 meaning in English
polarized line
Examples
- At present , surge control method for centrifugal compressor being used is commonly by least - flow method . it can ’ t make compressor working within operating condition area , sometimes starts the surge control system earlier , which will waste energy sources and depress economy benefit . even , its control system commonly consists of simulation instrument , can ’ t modify the changing surge curve of compressor in time and can ’ t control nonlinear surge curve preferably
目前,在用的离心压缩机的防喘振方法一般采用最小流量法,它不能充分使压缩机工作在其工况区,往往过早起动防喘振系统,浪费了能源,降低了经济效益。且控制系统一般采用模拟仪表构成,在压缩机的喘振线发生变化时不能及时修正,对非线性的喘振线不能较好的实施控制。 - Based on using the performance forecast model of centrifugal compressor , this paper the analyze is carried out on the performance forecast for centrifugal compressor and surge model of centrifugal compressor is established on its system . surge line of this system is obtained according to the performance similar principle . performance forecast software is compiled by using matlab at the same time
本文在离心压缩机性能预测模型的理论基础上,对离心压缩机进行性能预测分析,并建立系统的喘振模型,然后利用性能相似原理,得到离心压缩机系统喘振线,同时利用matlab编制离心压缩机性能预测软件,应用于防喘振控制中,较好地解决了离心压缩机因喘振现象而停机或为防止喘振现象的发生而过分加大回流量,造成能源浪费的问题。
