First, users' bad behavior
The user of the gas alarm should position the heating and cooling equipment adjacent to the combustible gas detector when utilizing the gas detector. The flammable gas detector should be kept away from air conditioners and heating units in order to prevent malfunctions brought on by improper setting. If the cold and warm air passes directly through the flammable gas detector while using an air conditioner or heater, it may result in errors in the platinum wire's resistivity. Users of the flammable gas detector should be careful to avoid electromagnetic interference.The body alarm installation should be shielded from electromagnetic interference by the installation position, installation angle, preventive measures, and system wiring. Users of flammable gas detectors should be aware of conditions that could lead to malfunction, such as dust, extreme heat, humidity, rain, etc. If an exhaust fan is required to be put in the area where a combustible gas alarm is situated, the leaked combustible gas will not be able to fully diffuse to the area around the combustible gas alarm, making it impossible to detect the leak in time. Yi didn't see the combatant.
Second, the construction process is not standardized;
The non-standard 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.
Third, maintain the gas detector
To detect gas concentration, the detector must communicate with the detection environment, so it is unavoidable for various polluting gases and dust in the environment to enter the detector, and the damage to the working conditions of the detector is an objective existence, flammable The working environment of the gas detector is relatively harsh, and many are installed outdoors. Poor maintenance will lead to errors or no detection of the gas detector. Therefore, regular cleaning and maintenance of the combustible gas detector is an important task to prevent failures.
The 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 malfunctions.
It is recommended to perform response detection on the standard gas used in the instrument before various instruments are used to ensure that the instrument truly plays a protective role. Flammable gas alarms and toxic gas alarms are also measured by a relative method like other analytical testing instruments: first, use a zero gas and a standard concentration of gas to calibrate the instrument, and get the standard curve and store it in Among the instruments, during the measurement, the instrument compares the electrical signal generated by the gas concentration to be measured with the electrical signal of the standard concentration, and calculates the accurate gas concentration value. Therefore, zero-calibrating the instrument at any time and calibrating the instrument frequently are essential work to ensure the accuracy of the instrument's measurement.
