摘要
分析流体传动系统中压力损失产生的原因,介绍液体在圆管呈层流和紊流两种流动状态时,直管内压力损失的计算公式,对输送管件、附件等局部阻力系数及压力损失计算方法进行探讨;提出减少流体传动中压力损失的方法。
This paper analyses the causes of the liquid in the tube was introduced laminar and turbulent flow of two kinds of state,the straight pipe pressure loss formula,for pipelines,accessories,local resistance coefficient and pressure loss calculation method to explore;proposed to reduce the pressure loss of fluid power transmission related methods.
