与 出烟孔 相关的网络例句 [注:此内容来源于网络,仅供参考]

If the resistance rises to the pre-set number(1245-1470Pa), the controller will send out signals, first to control the lift valve to do these operations: close the hole of the valve board to cut air current and stop filtering, and then to open the electromagnetic pulse valve to blow compressed air whose pressure is 0.5-0.7Mpa into filter bag with a short time(0.01-0.12s).

当含尘烟气由进风口进入灰斗以后,一部分较粗尘料在这时由于惯性碰撞、自然沉降等原因落入灰斗,大部分尘粒随气流上升进入袋室,经滤袋过滤后,尘粒被阻留在滤袋外侧,净化的烟气由滤袋内部进入箱体,再由阀板孔、出风口排入大气,达到收尘的目的,随着过滤过程的不断进行,滤袋外侧的积尘也逐渐增多,从而使除尘器的运行阻力也逐渐增高,当阻力增到预先设定值(1245-1470Pa)时,清灰控制器发生信号,首先控制提升阀将阀板孔关闭,以切断过滤烟气流,停止过滤过程,然后电磁脉冲阀打开,以极短时间(0.01-0.12s)向箱体内喷入压力为0.5-0.7Mpa的压缩空气,压缩空气在箱体内迅速膨胀,涌入滤袋内部,使滤袋产生变形、震动,加上逆气流的作用,滤袋外部的粉尘便清除下来掉到灰斗,清灰完毕之后,提升阀再次打开,除尘器又进入过滤状态。
