气力输送吸嘴的自转和公转

Rotation and Revolution of Suction Mouth Pneumatic Conveying

吸嘴是吸送式气力输送装置的关键部件。转动吸嘴的研制成功对提高吸煤机的生产能力起到了突破性的作用。转动吸嘴公转是在吸煤实验中发现的。转动吸嘴的公转 ,不仅扩大了它的工作范围 ,还能给它提供更加充足的可吸送物料。文中阐述了转动吸嘴公转现象产生的机理 ,推导出了转动吸嘴公转的数学公式。

Suction mouth is a key component of vaccum pneumatic conveying unit.The invention of the rotating suction mouth has play a breakthrough role in the promotion of turnout of coal suction machine.The revolution of the suction mouth is discovered in the experiment.The revolution of the mouth not only can exopend its working scope,but also the more and more materials can be sucked.The principle of the revolution of the mouth has been elaborated and the mathamatic formula of the revolution has been deduced which the condition of coal reclaim and loosing has been submitted.
