外旁通双管密相气力输送气量控制方式比较

The comparison of the by-pass double pipe dense phase air transportation control mode

分析了外旁通双管密相气力输送系统中各种气量控制方法,对其各自的优缺点进行了详细讨论。重点分析减压阀及减压阀与拉法尔管联合气量控制,为气力输送系统减压阀的选择和调节提供理论指导,指出可调式拉法尔管是今后气力输送气量控制发展的一个方向。

Has analyzed outside in the by-pass double pipeline dense phase air transportation system and each tolerance control method, has carried on the detailed discussion to its respective advantage and disadvantage. Mainly analyzes the pressure relief valve and the pressure relief valve with pulls the Farr tube union air volume control, provides the theory instruction for the physical strength expulsion system pressure relief valve choice and the adjustment, pointed out might the mode La Farr pipe is the next air transportation control development direction.
