How to reduce the failure of combustible gas alarms

Combustible gas alarm is a detection instrument installed to prevent safety accidents caused by gas leakage. The product is widely used in petroleum, chemical, iron and steel, water conservancy, metallurgy and other industries. In the course of use, the instrument will often appear common failure problems. To reduce the occurrence of these problems, in fact, in the process of using combustible gas alarms, as long as we pay attention to the following issues that need attention, we can easily reduce the occurrence of instrument failures. .

During use, attention should be paid to the setting of flammable gas alarms in explosion-proof places. For example, a type A factory that emits flammable gas should use explosion-proof flammable gas alarms, and the explosion-proof rating should not be lower than the corresponding explosion-proof rating required by current regulations. Users should also pay attention to the use of flammable gas detectors to avoid high temperatures, high humidity, steam, and soot. Do not place objects or hang objects on the detector. When the flammable gas alarm is installed near the air conditioner, it will cause the detection of the system to be deviated; the distance between the detection circuit and the power lines, Lighting lines and other strong electric circuits is small, and without the protection against electromagnetic interference, the system will also generate detection deviations. When using flammable gas detectors, users should pay attention to the factors that may cause malfunctions, such as: dust, high temperature, humidity, rain, etc. When an exhaust fan needs to be installed in a field where a combustible gas alarm is installed, if the exhaust fan is disposed adjacent to a flammable gas detector, the leaked combustible gas will not be able to fully diffuse into the vicinity of the combustible gas alarm, resulting in inability to timely detect it.

From the reliability considerations, at the same time, practice has proven that the use of combustible gas alarm system for more than 10 years due to component aging tends to increase, so the service period exceeds the use of the requirements, should be promptly replaced. The installed flammable gas detector cannot move the device anywhere. The user uses a flammable gas alarm as much as possible to use a sensor probe replaceable product for ease of use.

The flammable gas detector must detect the flammable gas information, and must communicate the detector with the detection environment. Therefore, it is unavoidable that various polluting gases and accumulated dust in the environment enter the detector, and the working conditions caused by the detector are damaged. It is an objective reality that the working environment of flammable gas detectors is rather harsh. Many of them are installed outdoors. Poor maintenance will result in errors or detection of combustible gas alarms. Therefore, regular cleaning and maintenance of flammable gas detectors is an important task to prevent malfunctions. Grounding should be regularly tested. Grounding cannot meet standard requirements or is not grounded at all. This can make flammable gas detectors susceptible to electromagnetic interference and cause problems.
