摘要
任何一种工程都应该投资少、成本低、效率高、运转稳定可靠,设计气力输送装置也应该是这样。本文提出了一个临界风速公式,用此公式能以最小的动力,得到最大的输送效果。
Any engineering should be possessed less investment, lower cost, higher efficiency and steady reliable operation, and so with the design of pneumatic transport device. This paper introduces a formula of critical wind velocity by which the higher transport efficiency could be obtained with the less power.
