纯蒸汽发生器故障分析 代码 故障原因 解决措施 PAL30-6 Compressed air low pressure 压缩空气压力过低 1. Check the line pressure and the availability of compressed air. 1. Verify the opening of the interception valve. 2. Verify the right working of the pressure switch PS30-6, and that the set value is not too high. 1. 检查管路压力和压缩空气的利用率 2. 检验截流阀事都开启 3. 检验压力阀PS30-6是否正常工作以及阀的设置是否太高 IAH09-1 Feed water pump motor overload 给水泵电机过载 1. Verify the rotation direction of the pump. 1. Verify and eliminate eventual air inside the pump body through the vent valve. 2. Check the pump motor amperage and the magneto-thermal switch setting (should be at the nominal plate value). Increase if too low. 1. 检验泵的转动方向 2. 检验并从通气孔中排净泵体内可能存有的空气 3. 检查泵的电流和保险闸的设置情况（通常为常用平板阀）。如太低即增加 纯蒸汽发生器故障分析 代码 故障原因 解决措施 LAHH09-25 Boiler high level 沸腾器水位过高 1. Verify that the set of high level is less that the set of high high level 1. Verify the correct opening of valve XV09-25 with the level. 2. Check the real and correct feeding with industrial steam. 3. Verify that the set value is not too low. 1. 检验高水平的设置是否低于高高水平的设置 2. 检验水平线阀门XV09-25是否正确开启 3. 检查工业蒸汽是否正常供给 4. 检验设置值是否不太低 PAL11-13 Industrial steam low pressure 工业蒸汽压力过低 1. Check the line pressure. 2. Verify that the steam filter YF11-11 is free and remove the eventual obstacles. 3. Verify the right working of the pressure switch PS11-13. 1. 检查管路压力 2. 检验蒸汽过滤器YF11-11是否畅通，排除可能的障碍物 3. 检验压力闸PS11-13是否正常工作 纯蒸汽发生器故障分析 代码 故障原因 解决措施 ASH12-11 High conductivity 传导率过高 1. Verify the set value for the alarm on the instrument. Increase it if too low. 2. Verify the integrity and the right working of the probe AE12-11. 1. Check the working of conductivity transmitter AIT12-11 analogue output. In case double-check the feed water qualities. 1. 检验仪表上警报器的设置值。如太低即升高 2. 检验探测器AE12-11是否正常 3. 检查传导率传输器AIT12-11的运行情况。尽可能再次查看给水的质量 LAL09-30 Feedwater tank low level 给水罐水位过低 1. Verify the quantity of water that arrives at the tank. 2. Verify the electric connection of the level switch LSL09
