If there is a problem when using the combustible gas detector, you can deal with it in this way
The combustible gas detector is composed of a detector and an alarm control host. It is widely used in petroleum, gas, chemical, oil depots and other petrochemical industries where combustible gas exists. important instrument.
There are two reasons for the failure of the combustible gas detector: the construction process is not standardized and the maintenance is not done properly. Both of them are possible factors that lead to the failure of the combustible gas detector. Irregularities in the construction process will cause the combustible gas detector to detect failures during use. If the combustible gas detector is not installed near the combustible gas that is easy to leak from the equipment, or is installed adjacent to the exhaust fan during installation, the leaked combustible gas cannot be fully diffused to the vicinity of the combustible gas detector, so that the dangerous leakage cannot be detected by the combustible gas in time instrument detection.
The combustible gas detector in the residence should be installed near the gas pipeline and stove in the kitchen. When the household uses natural gas, the gas detector should be installed within 300mm from the ceiling; when the household uses liquefied petroleum gas, the gas detection The device should be installed within 300mm from the ground. If the combustible gas detector is not reliably grounded and electromagnetic interference cannot be eliminated, the voltage will be affected and the detection data will be inaccurate.
Therefore, the combustible gas detector should be reliably grounded during construction. Combustible gas detectors and terminals are installed in places that are prone to collision or water ingress, causing electrical circuit breaks or short circuits. Non-corrosive flux must be used for welding, otherwise the corrosion at the joint will separate or increase the line resistance, which will affect the normal detection. Do not drop or drop the detector on the ground. Debugging should be carried out after construction to ensure that the combustible gas alarm is in normal working condition.
The maintenance of the combustible gas detector is also very important. Due to the harsh working environment of combustible gas detectors, many of them are installed outdoors and are often attacked by various dust and polluting gases. To detect combustible gas information, combustible gas detectors must communicate with the detection environment, so It is unavoidable for various polluting gases and dust in the environment to enter the detector, and the damage to the working conditions of the detector is an objective existence. If maintenance is not paid attention to, the detection of the combustible gas alarm will be blocked, resulting in An error or non-detection situation occurs. Therefore, regular cleaning and maintenance of combustible gas detectors is an important task to prevent failures.
