Hydrogen is the 1 colorless and highly flammable gas. If the concentration of hydrogen is too high, it may explode. Therefore, hydrogen alarms must be installed where there is a hydrogen leak to ensure safety. However, in order to better ensure the accuracy of the hydrogen alarm, we must do the relevant maintenance work. Do you know what aspects should be paid attention to during the maintenance of hydrogen alarm ? The following is a brief introduction by Yiyuntian:

hydrogen alarm should pay attention to the following aspects during maintenance:

1. Prevent the hydrogen alarm from falling from a height or from severe vibration.

2. The hydrogen alarm may not work properly when there may be high concentrations of gas.

3. There should be no strong magnetic field with great influence around the hydrogen alarm to avoid interference to the instrument. At the same time, pay attention to the reliable grounding of the shielded wire.

4. For open hydrogen leakage, if there is no good ventilation condition, it is easy to accumulate in a 1 part, resulting in excessive hydrogen concentration and accidents.

5. In order to ensure the measurement accuracy, the hydrogen alarm should be calibrated regularly. In general, it is recommended to calibrate every 6 months, and the calibration cycle is no more than one year.

6. Hydrogen alarms should not be stored or used in environments containing strong corrosive gases, nor should they be used in harsh environments (including high and low temperatures, high humidity, electromagnetic fields, strong sunlight, etc.).

7. If there is dirt on the surface of the hydrogen alarm, please wipe it gently with a clean soft cloth. Do not use corrosive solvents and hard objects to wipe the surface, otherwise it will cause scratches or scratches on the surface of the hydrogen alarm. damage.

To sum up, some aspects should be paid attention to during the maintenance of hydrogen alarm. When the alarm value set by the alarm is reached, the hydrogen alarm will send out an audible and visual alarm signal.In case of hydrogen leakage, timely cut off the leakage gas source, extinguish the open flame, dilute the hydrogen in the leakage area, and use the suction system to discharge the leaked hydrogen to the outdoor to prevent the hydrogen explosion from causing casualties.
