One of the main application areas of industrial fixed combustible gas detectors is the petrochemical industry, because the gas in petrochemical and other industries basically contains combustible gas. The use of fixed flammable gas detectors can well detect whether there is a flammable gas leakage in the indoor and outdoor environments, and it is also an important tool to ensure personal safety and production safety. Install the combustible gas detector at a specific location, the detector transmits the gas signal to the alarm instrument by converting the voltage and current signals, and then the alarm automatically displays the concentration of the lower limit of the combustible gas explosion. When personnel hear the sound and light alarm signal, some safety measures can be taken to prevent the occurrence of explosion accidents. So when using a fixed combustible gas detector, how to avoid the failure of the instrument?
How to avoid failure caused by industrial stationary flammable gas detectors?
1. Industrial fixed combustible gas detectors should be kept away from air conditioners and heating equipment when in use to avoid malfunctions caused by improper positions.
2. In the process of using the combustible gas detector, the user should also pay attention to preventing electromagnetic interference. The position, angle, protection measures and system wiring of the body alarm should prevent electromagnetic interference. When using the combustible gas detector, users also need to pay attention to factors that are likely to cause failures such as dust, high temperature, humidity, and rain.
3. When an exhaust fan needs to be installed in the place where the combustible gas detector is installed, if the exhaust fan is installed near the combustible gas detector, the leaked gas will not be able to fully diffuse to the vicinity of the combustible gas alarm, resulting in failure to detect in time and cause The detector cannot issue error indications such as alarm prompts.
4. When using a combustible gas detector, attention should also be paid to avoid high temperature, high humidity, steam and smoke. Do not place or hang objects on the detector. The installed combustible gas detector cannot be moved arbitrarily.
The maintenance and repair of the fixed combustible gas detector must be combined with the detection environment, so various polluted gases and dusts in the environment may enter the detector. In addition, the harm caused by portable gas detectors to the working environment is more objective, while the working environment of fixed flammable and toxic gas detectors is more complicated, many of which are installed outdoors, and poor maintenance will cause the body to alarm errors or fail to detect in place. Therefore, regular cleaning and maintenance of combustible gas detectors is an important task.
