Ammonia detector failure is mainly due to improper use caused by users, and do not understand the performance of the detector, incorrect equipment selection, not according to the norms of construction, maintenance and failure caused by inappropriate user needs. Analysis of user use, the reasons are as follows combustible gas detector failure, and proposed how to correctly use the combustible gas detector, the gas through the failure of the alarm occurs less.
1 , improper operation:
Ammonia detector users can use different gas detector development process, air conditioning and heating equipment near the combustible gas detector installation, when using air conditioning and heating equipment in the process, if the cold, warm airflow blowing directly over the combustible gas alarm, there is a possibility that will cause the combustible gas alarm platinum wire resistivity of the time change in the situation of a certain error, so the combustible gas alarms should be away from the Air conditioning, heating equipment, to avoid enterprises to set the corresponding location to choose the improper behaviour triggered failure. Users need to use combustible gas detector process we should also pay attention to anti-electromagnetic interference. Combustible gas alarm installation location, installation technology perspective, protection and management measures to analyse and social systems should be anti-electromagnetic interference in integrated wiring. Electromagnetic environment of combustible gas alarms on the impact of the main ways to study the following three main: airborne electromagnetic interference, power supply problems and other input data output line of narrow pulse group as well as improve the human body static electricity.
For example, when the combustible gas alarm close to the air-conditioning installation, it will cause the detection of the system deviation; detection line and power lines, lighting lines and other strong power lines with a small distance, but there is no anti-electromagnetic interference measures, the system will also produce detection deviation. Users in the use of combustible gas detectors, should pay attention to the factors that are likely to cause failure, such as dust, high temperature, humidity, rain, etc... When the place where the combustible gas alarm is installed needs to install a smoke exhaust fan, if the smoke exhaust fan is set up adjacent to the combustible gas detector, the leaking combustible gas will not spread sufficiently near the combustible gas alarm, resulting in failure to detect in time, and miss the opportunity to fight.
