What problems may occur when using combustible gas detector?
Combustible gas detector, as its name implies, is an instrument for detecting combustible gas for us, which can be used in fire fighting, petroleum, chemical industry, mining, laboratory and other industries. Moreover, the combustible gas detector is a precision instrument, so when using it, we must strictly follow the instructions above, otherwise the following problems may occur in use:
1. The operator does not understand the position placement problem.
For example, installing some exhaust equipment near the combustible gas detector may cause errors in the resistivity change of the platinum wire of the combustible gas detector, so the combustible gas detector should be far away from these equipment to avoid failure caused by improper installation position. Or the combustible gas detector is not located near the equipment where combustible gas is easy to leak, or it is located adjacent to the exhaust fan when it is installed, so the leaked combustible gas cannot fully spread to the vicinity of the combustible gas detector.
2, the lack of flammable gas detector alarm misunderstanding.
Many people think that as long as there is oil and gas leakage near the combustible gas detector, the controller should send an alarm signal, and if there is no alarm, the combustible gas detector may fail. This understanding is wrong. The detection object of combustible gas detector is combustible gas in the air, and the monitoring range is 0-100%. However, only when the concentration of combustible gas reaches the set value, the controller sends out an alarm signal, not when there is oil and gas.
3, installation and engineering problems.
It should be noted that non-corrosive flux is used for welding to prevent corrosion, and debugging should be carried out after construction to ensure that the combustible gas detector is in normal working condition.
4. There is no regular inspection and investigation.
In order to check and accept, many factories installed it when they built the factory, thinking that it would be done once and for all. There is no regular record and investigation, which leads to the problem when it is too late. Correct understanding and careful maintenance are a decisive condition for the normal work of combustible gas detector, so we can't help but pay attention to it.
