1) the compressed air piping line

压风管路
2) air-supply pipeline

供风管路
3) pipeline of fans

风机管路
4) spray gas pipeline

喷风管路
1.
A kind of spray gas pipeline was designed.

设计了一种喷风管路,用毕托管测量了气体实际出流速度,根据管道模型进行了水力学计算,同时还利用Fluent软件进行了相同条件下的数值模拟计算。
5) wind duct system

送风管路
6) induced pipe

引风管路
1.
The environment of negative pressure is usually generated by the function of induced pipe.
当引风管路中出现断口,负压环境的压力分布势必受到影响,达不到工作环境的负压要求。
