气动放大器目前通用于QDZ-Ⅱ仪表的气动变送器、电-气转换器以及气动调节器,它主要起着功率放大的作用——压力、流量放大的作用。本文介绍的是一种目前我国广泛采用的耗气式功率放大器。一般情况下,比较容易产生故障的原因主要是容易被压缩空气中的油、水及微小尘粒所沾污。如果有沾污,可先把放大器全部拆下来,用酒精或汽油把所有的零件全部清洗一下,然后把这些零件放在自然通风处吹干。再用钢丝(φ0.1mm)或者其它毛发,
Pneumatic amplifier currently used in QDZ-Ⅱ instrument pneumatic transmitter, electric - gas converters and pneumatic regulator, which mainly plays the role of power amplification - pressure, flow amplification. This article describes a currently widely used gas-consuming power amplifier in our country. Under normal circumstances, the more likely cause of failure is mainly easy to be compressed air in the oil, water and small dust pollution. If there is contamination, the amplifier can be removed all the first, with alcohol or gasoline to clean all the parts all about, and then these parts on the natural ventilation and dry. Re-use steel wire (φ0.1mm) or other hair,
