Combustible gas detectors are professional instruments for preventing gas leaks. They can monitor the concentration of combustible gas leaks in real time and are widely used in petroleum, chemical, catering, metallurgy, integrated pipe corridors, nine small places and other fields.
In order to strengthen the safety of gas use in the catering industry and effectively curb the occurrence of gas safety accidents, the state has issued a number of laws and regulations requiring the installation of gas alarms.
How to install and use combustible gas detectors?
1 Combustible gas detectors are precision instruments. Be careful when installing them to avoid breaking the probes.
2 Gas detectors should be selected within a radius of 1 meter around valves, pipe interfaces, gas outlets or leaks, as close as possible, but do not affect the operation of other equipment. At the same time, try to avoid high temperature and high humidity environments, do not exceed the operating temperature range and humidity range of the detector, and avoid external influences such as splashing water, oil and the possibility of mechanical damage.
3 There are many ways to install gas detectors. They can be installed on the roof, on the wall or by holding pipes. Ensure that the installation is firm and reliable, and consider facilitating the maintenance and calibration of the detector.
4The installation height of the gas detector should be determined according to the nature of the gas:
★ When the density of the measured gas is less than that of the air, it should be installed 30-60 cm from the ceiling, and the sensor should be downward;
★ When the density of the measured gas is greater than that of the air, it should be installed 30-60 cm from the ground, and the sensor should be downward.
5The combustible gas detector is a safety instrument with sound and light display functions. It should be installed in a place where the staff can easily see and hear it, so as to eliminate hidden dangers in time.
6When the alarm is installed in an area susceptible to electromagnetic interference, armored cables or cables with metal protective tubes should be used.
7The combustible gas alarm controller should have an indicator sign corresponding to the location of the detector or a distribution map of the detector.
What should I do if the gas detector keeps alarming during use?
Users need to understand the reason why the gas detector keeps alarming. It may be that a combustible gas or toxic and harmful gas leak is detected, or it may be a problem with the equipment itself.
Users need to know how to check the gas detector. During the inspection, you can check whether the detector is contaminated, blocked, or has other problems. By regularly checking and cleaning the detector, you can ensure that it is working properly.
If the gas detector continues to alarm, the user needs to understand how to calibrate the device. Calibration is to ensure that the detector can accurately detect gas concentrations. If the sensitivity of the gas detector is set too high, you can try to reduce the sensitivity. This will make the device less sensitive to small changes in gas concentrations and reduce false alarms and frequent alarms.
If there are factors such as high temperature, high humidity, and dust in the environment that interfere with the normal operation of the gas detector, you can take measures to reduce these interferences. For example, you can install dust covers and desiccants around the device.
If none of the above methods can solve the problem, it may be that the device itself is faulty. At this time, you need to further check the device, such as checking whether the circuit board is working properly, replacing the battery, etc.
If the user cannot solve the problem of continuous alarms of the gas detector, you can seek professional help. You can call the manufacturer or ask for help from professionals.
