1. Find out the leak point of the device
First of all, it is necessary to find out what the leakage points of the device are, analyze their leakage direction, pressure and other factors, and at the same time draw the distribution map of their probe positions, which are divided into three grades: I, II, and III according to the severity of the leakage. At the same time, according to the density of the leaked gas, combined with the air flow trend, a three-dimensional flow trend diagram of the leakage is synthesized, and an initial set point scheme is made at the downstream position of the flow. Then, according to the specific factors such as the wind direction and airflow direction of the place, determine the direction of leakage of combustible gas if a large amount of leakage occurs.
2. The use of combustible gas detectors should avoid electromagnetic interference
There are three main paths for the electromagnetic environment to affect the combustible gas detector: First, the disturbance of electromagnetic waves in the workplace. The second is the narrow pulse group on the power supply and other input and output lines in the fixed gas detector. The third is the static electricity generated by the human body.
3. Use explosion-proof combustible gas detector
Because explosion accidents may occur in many places, we should choose an explosion-proof combustible gas detector when choosing a combustible gas detector. The explosion-proof level should not be lower than the corresponding level of the current specification.
4. Avoid damage to the probe
In the installation of the combustible gas detector, care must be taken not to cause damage to the probe of the alarm that is in contact with other sensors, because the probe is the most critical component in the alarm. Once damaged, it may cause damage to the alarm. It is a more serious injury that affects the correct alarm of the alarm.
