本文根据流体运动的基本方程通过量级分析方法,从理論上说明了影响水击现象得因素的数量级大小,并給出了这些影响因素的判据。写出了一般情况下由特征理論所得的联鎖方程和水击波速公式。同时,对各种形式的管路系統及不同的調节方式作了水击图解实例,图解法的結果表明:复杂管路中边界条件,启閉方式对水击压强有显著影响,并可看出其变化过程的某些規律。
In this paper, according to the basic equations of fluid motion, the order of magnitude of the factors affecting the water hammer phenomenon is theoretically explained by the method of order of magnitude, and the criterion of these factors is given. Write out the interlocking equation and the water hammer wave velocity formula which are generally obtained by the theory of features. At the same time, various types of piping systems and different adjustment methods were made water hammer graphic example, graphic method results show that: the complex pipeline boundary conditions, opening and closing methods have a significant impact on water pressure, and can see Some of the rules of the changing process.
