气力输送系统(动压输送)存在着能耗大,管道易磨损,被运物料有一定限制且物料易破碎等缺点。特别是能耗问题影响较大,而在能耗中起很大作用的压力损失又与输送系统的有关参数,特别是被输送物料的气流速度、输送管径、输送量等因素有着密切关系,所以正确地选择和确定气力输送系统的有关参数将为合理地使用该系统奠定良好基础。为此本文就气流速度的选择,管
Pneumatic conveying system (dynamic pressure transmission) there is a big energy consumption, pipe easy to wear, there are certain restrictions on the material being transported and the material is easy to break and other shortcomings. In particular, the impact of energy consumption is greater, and the pressure loss that plays a large role in energy consumption is closely related to the relevant parameters of the conveying system, in particular, the flow velocity of the conveyed material, the diameter of the conveying pipe and the conveying capacity, Therefore, the proper selection and determination of the relevant parameters of pneumatic conveying system will lay a good foundation for the rational use of the system. To this end the choice of the speed of the gas pipe
