摘要
本文介绍了无创呼吸机总体组成结构、叶片型式。讨论了不同βb2角(叶片出口的几何角)对无创呼吸机效率、功率以及压力的影响,同时介绍了怎样确定微涡轮的叶片数和在无创呼吸机微涡轮中采用后弯式叶片的优点。
Describes briefly the constitution and structure, the pump blade type of a special non-invaslve ventilator. Discusses the influence of different angles on the efficiency, the power and pressure of ventilator as well as the method to determine the number of blades. Finally, selects the bent-type pump blade to De used in this type of non-invasive ventilator. The experiment result shows that the performance of the ventilator is similar to those of foreign products of the same type.
