What are the main points of attention in the use of gas detectors?
First, to detect gas concentration, the detector must communicate with the detection environment, so it is unavoidable that various polluting gases and dust in the environment enter the detector, and the damage to the working conditions of the detector is objective. Existing, the working environment of flammable gas detectors is relatively harsh, many are installed outdoors, and poor maintenance will lead to errors or no detection of flammable gas detectors. Therefore, regular cleaning and maintenance of the combustible gas detector is an important task to prevent failures.
Grounding should be checked regularly. If the grounding fails to meet the standard requirements, or is not grounded at all, the flammable gas detector will also be susceptible to electromagnetic interference and cause failure.
Second, in the process of using the gas detector, the user of the gas alarm may cause errors in the resistivity of the platinum wire of the flammable alarm. Users should also pay attention to preventing electromagnetic interference when using the flammable gas detector. The installation position, installation angle, protective measures and system wiring of the body alarm should be protected against electromagnetic interference. When using the combustible gas detector, users should pay attention to factors that may cause failure, such as dust, high temperature, humidity, etc. When an exhaust fan needs to be installed in the field where the combustible gas alarm is installed, the combustible gas detector is set adjacent to it, and the leaked combustible gas will not be able to fully diffuse to the vicinity of the combustible gas alarm, resulting in inability to detect in time and miss the fighter. When using the flammable gas detector, users should also pay attention to avoid places where high temperature, high humidity, steam and oil fumes can be reached. Do not place or hang objects on the detector. The installed flammable gas detector cannot move the position of the device arbitrarily. When using the body alarm, users should try to choose products with replaceable sensor probes for ease of use.
Third, the irregular construction process will cause the flammable gas detector to detect faults during use. If the flammable gas detector is not located near the equipment that is prone to leakage, or is installed adjacent to the exhaust fan, the leaked gas cannot fully diffuse to the vicinity of the flammable gas detector, so that the dangerous leakage cannot be flammable in time. Sexual gas detector detection. If the flammable gas detector is not reliably grounded, it cannot eliminate electromagnetic interference, which will inevitably affect the voltage and cause inaccurate detection data. Therefore, the flammable gas detector should be reliably grounded during the construction process. The flammable gas alarms and wiring terminals are located in places prone to collision or water entry, resulting in open circuit or short circuit of electrical circuits. Welding must use non-corrosive flux, otherwise the joints will be corroded and detached or the line resistance will increase, which will affect the normal detection. Do not drop or drop the detector on the ground. Debugging should be carried out after construction to ensure that the body alarm is in normal working condition.
