确定管路液体的压力降,一般要经长时间的计算。本文介绍一种新的图解法,确定管路的压力降,可用很短的时间即可得出结果。液体沿管路流动时,由于摩擦的作用,使液压系统的一部分压力能量变为热能,从而产生了压力降。但是,可通过合理的设计和选择管路尺寸,将压力降减至最小。管道的内径是影响液体压力降最重要的因素。一般对一定的
Determine the pressure drop of the pipeline liquid, generally after a long time of calculation. This article presents a new graphical method to determine the pressure drop in a pipeline, which can be achieved in a short time. When the liquid flows along the pipeline, a part of the pressure energy in the hydraulic system becomes thermal energy due to the friction, so that a pressure drop occurs. However, pressure drops can be minimized by rational design and selection of pipe sizes. The inner diameter of the pipe is the most important factor that affects the pressure drop across the liquid. General to certain
