 氢气发生器偶尔会出现以下一些现象,我们在遇到时该如何处理呢,上孰机电设备简单分析下现象的原因和解决方法。

  一、氢气发生器漏气

  压力表数值小于设定值(设定值一般为0.3MPa)或为零且输出流量数值大于实际用气流量值。

  解决方法:用肥皂水试下干燥管两端接口是否有气泡,有汽包说明干燥管漏气,此时拧下干燥管重新装配或更换密封圈或更换干燥管。如若干燥管不漏气则用封堵把氢气输出口堵上让仪器自检,自检结果仪器漏气则打开机壳检查仪器内部气路各个接口是否有漏气点,检查不出来建议供应商技术部以获得,自检不漏气则检查仪器以后的气路部分找出漏气点。

  二、氢气发生器干燥管有水

  原因:1、硅胶质量差或没完全再生,此时更换好的硅胶或烘烤时间加长一般在120摄氏度12小时。

  2、返液,更换气水分离器或重新调试。

  三、氢气发生器气量不足

  原因:仪器漏气,电解液浓度低

  解决方法:仪器自检看是否存在漏气,添加电解质(一般为氢氧化钾)

  四、氢气发生器过压

  氢气发生器压力超出设定值且数码显示表数字不停地变动和闪跳

  解决方法:压力控制器设定位置移动或损坏,重新调节压力控制装置或更换压力控制装置。气水分离器内部压力过大,松下气水分离器旋盖以减低其内部压力或更换气水分离器。

Occasionally, some of the following phenomena appear in hydrogen generator. How to deal with them when we encounter them? Which mechanical and electrical equipment simply analyzes the causes and solutions of the following phenomena.

1、 Leakage of hydrogen generator

The pressure gauge value is less than the set value (the set value is generally 0.3MPa) or zero, and the output flow value is greater than the actual gas flow value.

Solution: use soapy water to test whether there is air bubble at the interface at both ends of the drying pipe. If there is a steam drum, it indicates that the drying pipe leaks. At this time, screw off the drying pipe to reassemble or replace the sealing ring or replace the drying pipe. If there is no air leakage in some dry pipes, the hydrogen output port shall be blocked with a plug to let the instrument self check. If there is air leakage in the instrument as a result of self check, the enclosure shall be opened to check whether there is any air leakage point in each interface of the internal air circuit of the instrument. If there is no air leakage in the self check, the supplier's technical department shall be advised to obtain it. If there is no air leakage in the self check, the air circuit part of the instrument shall be checked to find the air leakage point.

2、 Water in drying pipe of hydrogen generator

Reasons: 1. The quality of silica gel is poor or not completely regenerated. At this time, the replaced silica gel or the baking time is generally prolonged at 120 ℃ for 12 hours.

2. Return liquid, replace gas water separator or re Commission.

3、 Insufficient gas volume of hydrogen generator

Cause: air leakage of the instrument and low concentration of electrolyte

Solution: self check the instrument to see if there is air leakage, and add electrolyte (generally potassium hydroxide)

4、 Hydrogen generator overpressure

The pressure of hydrogen generator exceeds the set value, and the number of digital display meter keeps changing and flashing

Solution: move or damage the set position of the pressure controller, readjust the pressure control device or replace the pressure control device. If the internal pressure of the gas-water separator is too large, loosen the cover of the gas-water separator to reduce the internal pressure or replace the gas-water separator.
