What should I do if the hydrogen alarm shows a large numerical error or no indication?

The main function of the hydrogen alarm is to detect the concentration of hydrogen gas in the air. When the concentration in the air reaches a certain concentration, the hydrogen alarm will automatically sound and light alarm to remind the staff to take corresponding measures in time To avoid major accidents. However, when we use the hydrogen alarm, sometimes the display value error is large or there is no indication.

the error of the fault 1. display value is large

p> Part of the reason for this failure is that the hydrogen alarm probe has not been effectively calibrated for a long time, as a result, the sensitivity of the sensor is greatly reduced, resulting in inaccurate measurement results of hydrogen gas concentration.In addition, according to the analysis of drilling site operation, the hydrogen alarm probes are mainly distributed at the wellhead, drill floor and other positions, which makes the surface and gas flameproof membrane easily polluted by mud and drilling fluid, and the flameproof membrane is also easily soaked by rain in rainy weather. These are hydrogen alarm indications that can cause errors.

Handling:

1. Check the usage of the hydrogen alarm probe regularly, clean the flameproof membrane regularly, and calibrate the sensor regularly.

2. Install a rainproof device for the probe installed in the open air.

fault 2. no indication

Handling:

1. for the treatment method of blocking the flameproof sheet, remove the probe, remove the metal flameproof sheet, and soak the filter membrane in clear water with a small amount of detergent for about half an hour, then use a brush to remove the dirt. We can also use pliers to clamp the flameproof sheet, use a high-pressure air gun to repeatedly blow and wash the filter membrane, dry it, and then install it on the hydrogen alarm.

2. For hydrogen alarms with sensor failure, we can directly replace the new sensor.

To sum up, it is the possible reason why the hydrogen alarm has a large display value error or no display value and the corresponding solution. When we encounter some minor faults in the hydrogen alarm, we should pay attention to analyze the causes, analyze the causes at the root and solve them. Only in this way can we better ensure that the hydrogen alarm can be maintained in a normal and stable state of use.
