The cause of the failure caused by the integrated combustible gas detector does not exclude two points: the construction process is not standardized and maintenance has not been done. Both have the possibility of causing a malfunction of the flammable gas detector. Non-standard construction procedures can cause flammable gas detectors to detect failures during use. If the flammable gas detector is not located in the vicinity of the flammable gas where the device is liable to leak, or is installed adjacent to the exhaust fan during installation, the leaked combustible gas cannot fully diffuse into the vicinity of the flammable gas detector, so that the leakage danger cannot be ignited in time. Gas detector detection.

The flammable gas detector in the house shall be installed near the gas pipelines and stoves in the kitchen. When the resident uses natural gas, the ceiling of the gas detector shall be installed within 300 mm from the ceiling; when the resident uses liquefied petroleum gas, gas The detector should be installed within 300mm from the ground. If the flammable gas detector is not grounded reliably, electromagnetic interference cannot be eliminated, which will affect the voltage and cause faults with inaccurate detection data.

Therefore, the flammable gas detector should be reliably grounded during construction. Flammable gas detectors and wiring terminals are set up to be vulnerable to collisions or ingress of water, causing electrical circuit lines to open or short circuit. Welding must be done with non-corrosive fluxes, otherwise joints will erode off or increase line resistance, affecting normal detection. Do not drop or drop the detector on the ground. After the completion of construction, commissioning should be carried out to ensure that the combustible gas alarm is in normal operation.

It is also important to maintain the flammable gas detector. Due to the harsh working environment of flammable gas detectors, many of them are installed outdoors and often suffer from various dust and polluting gases. The flammable gas detector must detect flammable gas information and must communicate with the detector environment. Therefore, it is unavoidable that various polluting gases and accumulated dust in the environment enter the detector. The damage to the working conditions caused by the detector is an objective existence. If the maintenance is not emphasized, the detection of the combustible gas alarm will be hindered. As a result, an error or no detection occurs. Therefore, regular cleaning and maintenance of flammable gas detectors is an important task to prevent malfunctions.

In addition, it should be noted that the grounding should be regularly tested, grounding can not meet the standard requirements, or not grounded at all, it will make the flammable gas detector susceptible to electromagnetic interference, resulting in failure. Prevent component aging. From the reliability considerations, at the same time, practice has proven that the flammable gas detector service period of more than 10 years of the system caused by component aging tends to increase, so the service period exceeds the use of the requirements, should be promptly replaced.
