在确定液压系统元件的尺寸时,压力损失是一个很重要的影响因素。由于压力损失的计算十分复杂、费时,所以人们常常利用经验公式近似地计算液压系统的压力损失。现在我们可以利用一种新的图解法迅速而准确地求出管路系统中的压力损失。要保证液压系统具有良好的工作性能,在液体流动过程中就不应产生过多的压力损失。但是,液体流经控制阀、油缸、阻尼孔、弯管时会产生少量的能量损失即压力损失。当液体 Pressure loss is a very important factor in determining the size of hydraulic system components. Because the calculation of pressure loss is very complicated and time-consuming, people often use the empirical formula to approximate the hydraulic system pressure loss. Now we can use a new graphical method to quickly and accurately find the pressure loss in the pipeline system. To ensure the hydraulic system has a good working performance, in the liquid flow process should not produce excessive pressure loss. However, liquid flows through the control valve, cylinder, orifice, elbow will produce a small amount of energy loss that pressure loss. When liquid
