How to maintain the gas detector?
With the continuous development of my country's industry, various flammable, explosive, toxic and harmful gases are also produced in the production process. Frequent gas explosions and gas poisoning accidents have made factories and enterprises aware of the importance of gas detectors.
The gas detector is a precision machine, which can detect the gas environment in the factory area in real time and protect the safety of the personnel in the factory area. However, the gas detector needs to be properly maintained and maintained before it can be used normally. How should the gas detector be maintained?
1. Keep away from moisture, rain and corrosive liquids, ensure that the surface of the instrument is clean and dry, clean it well, and ensure that the surrounding environment is also clean and tidy. When cleaning and wiping, use a soft cotton cloth dipped in clean water to wipe gently. Remember to dry it in time, and never use chemicals, detergents, or high-concentration detergents for cleaning;
2. Check regularly at the appropriate time, don’t forget the calibration and impact test, the temperature of the environment during use should not be too low or too high, it should be moderate, to prevent electronic components, always wipe the detection hole of the gas detector, Keep the hole tube unobstructed, try not to let the liquid enter the hole, if it enters the detection hole, place the instrument down to let the liquid flow out of the hole, do not knock or shake the machine violently, nor drop it or use it roughly;
3. Do not knock or shake the machine violently, nor drop it or use it roughly. Always check whether the sealing ring is intact, whether there is any damage to the four-way valve and condensate, and check the membrane of the air pump. Check whether the sheet is intact, so as to prevent air leakage in the gas system;
4. The filter paper should be replaced regularly, and the sensor should be used within the specified time. There may be interference between different sensors. Pay attention to electromagnetic interference, prevent component aging, and replace parts in time;
5. To ensure that the test results are not affected, attention should be paid to the flow rate of the instrument. The value should not be too large or too small. In some cases, it is 30/h. We must prevent the inaccurate measurement of the instrument. When testing the concentration measurement range, we must Test within the limits of the assay.
Maintenance is to enable the gas detector to monitor the gas environment for the factory and enterprise more accurately for a longer period of time, and to protect the life safety of the operator and the property safety of the factory at all times.
