Relevant Operation Introduction for Combustible Gas Detectors
When installing combustible gas alarms, they should be kept away from air conditioning and heating equipment to avoid problems caused by improper orientation.
Users should also pay attention to preventing electromagnetic interference when using combustible gas detectors.
The orientation, viewpoint, protective measures, and system wiring of the combustible gas alarm device should be protected against electromagnetic interference.
There are three main pathways through which the electromagnetic environment affects combustible gas detectors:
(1) Airborne electromagnetic wave disturbance;
(2) Narrow pulse trains on power and other input/output lines;
(3) Human body static electricity.
Other users should also pay attention to the setting of combustible gas detectors in explosion-proof places. For example, Class A factories that emit combustible gases should use explosion-proof combustible gas alarms, and their explosion-proof level should not be lower than the corresponding explosion-proof level requirements of current regulations.
Users using combustible gas detectors should also pay attention to avoiding areas with high temperatures, high humidity, steam, and oil fumes. Do not place or hang items on the explorer.
The installed combustible gas detector cannot be moved freely. Users using combustible gas alarms should try to choose products with replaceable sensor probes for ease of use.
The combustible gas detector should be reliably grounded during the construction process. Non corrosive soldering flux must be used for welding, otherwise the joint will corrode and detach, or adding line resistance will affect normal exploration.
The explorer cannot be dropped or thrown to the ground. After construction, debugging should be carried out to ensure that the combustible gas alarm is in normal working condition.
Regularly cleaning and maintaining the combustible gas detector is an important task to avoid malfunctions.
Grounding should be checked regularly. If the grounding is not qualified or the base is not grounded, it can also cause electromagnetic interference and malfunction of the combustible gas detector. Avoid problems caused by component aging.
From a reliability perspective, the internship also confirmed that systems with a service life of more than 10 years for combustible gas detectors tend to have more problems caused by component aging. Therefore, if the service life exceeds the requirements of the application rules, it should be replaced in a timely manner.
