For some industrial environments where hydrogen may exist, it is necessary to install a hydrogen alarm, so that once a hydrogen leak occurs, when the alarm value set by the hydrogen alarm is reached, an audible and visual alarm signal will be issued, so as to prevent casualties caused by hydrogen explosion. However, as a kind of electronic equipment, hydrogen alarm will inevitably need to do related maintenance and repair work in the process of use. Do you know the hydrogen alarm maintenance precautions? The following is an introduction by Yi Yuntian:

hydrogen alarm maintenance matters needing attention:

1. In general, the hydrogen alarm should be overhauled once a year, usually at the same time as the annual overhaul of the factory.

2. For operations that may cause output fluctuations, prior approval must be obtained from the hydrogen alarm technician.

3. During maintenance and repair of hydrogen alarm, it is strictly prohibited to plug and unplug circuit components and connectors, or use electricity to repair or replace electronic components.

4. Maintenance personnel of hydrogen alarm must have skilled maintenance skills, and daily maintenance must be checked and operated by more than two people.

5. If fire analysis is not carried out on the explosion-proof site, it is strictly prohibited to overhaul and replace the electronic components with electricity during the maintenance and repair of the hydrogen alarm.

6. Recheck for leaks after overhauling the hydrogen alarm or replacing the sampling device, pretreatment system, and detector components.

7, keep the sampling device, pretreatment system and instruments clean and sanitary, prevent acid-alkali solution and water from splashing on the hydrogen alarm, and pay attention to protect the glass device from damage.

8. After maintenance, the hydrogen alarm must be safely grounded.

To sum up, it is the hydrogen alarm maintenance and maintenance precautions. Of course, in addition to paying attention to maintenance and repair matters, in the daily work process, we should also check other aspects of the hydrogen alarm to ensure the normal operation of the equipment, thereby improving work quality and efficiency.
