What problems may arise when using a combustible gas detector?
As the name suggests, the combustible gas detector is an instrument for us to detect combustible gas, which can be used in fire protection, petroleum, chemical, mining, laboratory and other industries. Moreover, the combustible gas detector is a precision instrument, so we must strictly follow the instructions above when using it, otherwise the following problems may occur during use:
The problems that may arise when using a combustible gas detector are as follows:
1. The operator has a position placement problem because he does not understand it.
For example, installing some exhaust equipment close to combustible gas detectors may cause errors in the resistivity of the platinum wire of the combustible gas detector. Therefore, the combustible gas detector should be far away from these devices to avoid failures caused by improper installation. Or the combustible gas detector is not installed near the equipment that is prone to leaking combustible gas, or it is installed adjacent to the exhaust fan during installation, so the leaked combustible gas cannot be fully diffused to the vicinity of the combustible gas detector.
2. Lack of misunderstanding of combustible gas detector alarm.
Many people think that as long as there is oil and gas leakage near the combustible gas detector, the controller should send out an alarm signal. If there is no alarm, the combustible gas detector may malfunction. This understanding is wrong. The detection object of the 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 will send out an alarm signal, not when there is oil and gas.
3. There are problems in the installation and engineering process.
It should be noted that non-corrosive flux is used for welding to prevent corrosion. At the same time, 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 and thought it was done once and for all. There is no regular record and investigation, and it is too late when the problem occurs. Correct understanding and serious maintenance are a decisive condition for the normal operation of combustible gas detectors, so we must pay attention to them.
