How to maintain the hydrogen sulfide gas detector and what are the methods
Hydrogen sulfide detector is an instrument tool used to detect the leakage or concentration of hydrogen chloride gas. It can select and match different parameters according to the same environment. There are two physical or electrochemical methods available on the market. Its electrochemical principle is to use gas sensors to detect the presence of hydrogen chloride gas in the environment, convert it into readable data through current signals and output or edit it. So what should be done for the maintenance of hydrogen sulfide gas detectors?
1. Clarify responsibilities and strengthen management
Assign a dedicated person to manage the hydrogen sulfide gas detector, and the responsible person receives professional training to master the structure, working principle, and basic maintenance skills of the alarm. Responsible for establishing and improving all basic data, drawing a detector distribution map on the device layout based on the detector distribution, and pasting the distribution map on the controller panel. Responsible for daily inspection and maintenance, and keeping relevant records.
2. Conduct inspections
Regularly inspect the hydrogen sulfide gas detector and keep inspection records. Press the self test system button once a week to check the operation of the system. Conduct a visual inspection once a week, including checking the connection parts, movable parts, display and control knob, checking the fault light, checking the explosion-proof sealing parts, fasteners, and explosion-proof pipes of the detector, checking whether the inlet channel of the detector is blocked, and checking the waterproof condition of the detector.
3. Timely maintenance
Purchase a certain number of commonly used accessories, strengthen maintenance, especially for vulnerable parts such as detectors, waterproof covers, explosion-proof tubes, and audible and visual alarms. If problems are found, they should be repaired and replaced in a timely manner.
4. Reasonable setting of monitoring points
When dismantling the detector and changing the detection point, it is necessary to fully consider the equipment and facilities, process devices, diffusion and accumulation of hydrogen sulfide gas, and comprehensively consider the effective range of the detector. Reasonably set the detection point to ensure that the detector covers all hydrogen sulfide gas release sources, without monitoring dead spots, and ensure accurate and reliable detection.
5. Timely verification to ensure accuracy and reliability
Detectors that have been repaired or changed in installation position should be promptly calibrated and adjusted. The hydrogen sulfide gas detector in use should be calibrated strictly according to the calibration cycle. Detectors that are unstable in operation or severely contaminated by oil and gas should be promptly verified and calibrated to confirm whether they are damaged. The hydrogen sulfide detector that has been verified as unqualified cannot be used anymore, and should be repaired or replaced in a timely manner.
