入口管 meaning in Chinese

inlet pipe
inlet tube

Based on a two - dimension model for the flow field in catalytic converter , the flow field and pressure loss in catalytic converter with different inlet headers are simulated
摘要利用催化转化器流场的二维模型对多种入口管结构的催化转化器流动分布和压力损失进行了数值计算，并提出一种组合型入口管。
Hot air cnters into stirring and crushing and drying chamber from the bottom of drier with suitable atomizing speed . it exerts strong shearing , blowing , floating and rotating effect to raw material . therefore raw material is granulated through centrifuge , shearing , impacting and friction effect
热空气由入口管以适宜的进风速度从干燥机底部旋转进入搅拌粉碎干燥室，对物料产生强烈的剪切、吹浮、旋转作用。
The experimental and simulation results show that using the improved structure of inlet header can greatly improve flow uniformity , decrease pressure loss , enhance the efficiency of twc , attribute to prolonging the service life of the machine , and lessen the power decrease caused by twc , but the light - off time of twc is retarded
通过模拟与试验表明，与常规结构催化转化器相比，组合型入口管可明显改善流动均匀性，降低压力损失约1 / 4 ，提高催化转化器效率，延长使用寿命，减小对发动机动力性的影响，但起燃变慢。
