不好意思，有点长，翻译不透，请大家看着改。？ 在设备的滤袋隔板上下游设有差压变送器接口，差压变送器将气流流经滤袋形成的压降通过电信号传入 dcs ，对滤袋的工作状况进行监测。当经过反吹清灰，压降仍高于允许压降，则需要延长阀门的通电时间（即阀门开启至关闭的持续时间），或将反吹间隔时间调短；如压降仍高于允许压降，则需要更换滤袋。差压变送器设有切断阀组和反吹甩头，便于检修和清理变送器接管内的粉尘。 the connections for differential pressure transmitter are set on upstream a downstream of filter bag clapboard, the differential pressure transmitter will transmit gas pressure to dcs through electricity signal, and monitor the operation condition of filter bag. if the filter do with blow back cleaning, and the pressure drop is higher than allowable pressure drop, the power supply time of valve (time from valve start to close) shall be increased, or decrease blow back duration time; if the pressure drop is still higher than allowable pressure drop, the filter bag need to be replaced. the differential pressure transmitter is equipped with amputator and blow back plug, in order to maintain and clean dust in transmitter pipe. 查看更多
