中文拼音 [qìdònglìzhōngxīnzhóu]
氣動力中心軸
英文
aerodynamc center axis-
To meet the need of developing the simulator of the whole flow sheet of the mathematical plant, mathematical model and simulation software of the plant is developed. in the process of modeling, thermotical character and mechanical character of centrifugal compressor are emphased. thermotical character is about section parameters and character curves ; mechanical character is about rotor ' s vibration and axial force
在建模過程中，重點對離心式壓縮機的熱力特性和機械特性做了較深入的研究，其中熱力特性著重於離心式壓縮機中的氣流在各個關鍵截面參數和特性曲線，機械特性著重於壓縮機轉子軸系的振動和軸向力。It can also determine the fault spot and reason. this technology has been used in some technological fields and proved efficient. it has promoted the revolution of maintance system and the historial protection is replaced by preventive maintenance. with this technology, we can improve the reliability of machine and decrease the maintance fee. recently, reserch has pick up a fervent pace in the area of fault diagnosis of electrical machines. the paper simply analyzes the fault reason of electrical machines, stressly describes and explores the methods of condition monitoring and fault diagnosis such as partial discharge, stator current, rotating speed, vibration etc. fault prognosis is now include diagnostic feature, reason, spot. prodigious improvement in signal processing hardware and software has made this possible. primarily, these techniques depend on locating specific harmonic components of the fault. these harmonic components are usually diffirent for diffirent types of faults. automated tools such as fuzzy logic based system is also simply presented in the paper
