How should the mine four-in-one Gas Detector be better maintained?

How should we maintain and check the mining four-in-one Gas Detector used in real life?

In fact, the four-in-one Gas Detector is widely used in the coal mining industry, but in addition to using it, many units rarely perform regular maintenance and inspection. For example, in the coal mining industry, the disregard of life by coal mine managers, the negligence of safety personnel, the violation of regulations by operators, and the violation of safety regulations by underground personnel will directly or indirectly cause coal mine safety accidents. However, most coal mine safety in my country The problems existing in the monitoring and monitoring system and equipment cannot be ignored. Let me take the coal mine unit as an example to illustrate the necessity of regular testing of the four-in-one Gas Detector.

1. We need to test the four-in-one Gas Detector regularly and on time, so as to find the fault of the four-in-one Gas Detector and the accuracy of the monitoring instrument at any time; we must choose a high-performance, new monitoring system to prevent the use of old-fashioned , Outdated equipment and machines to avoid potential safety hazards.

2. The choice of monitoring equipment needs to consider some external factors such as the specific use environment, use conditions, and use times. In addition to the four-in-one Gas Detector itself, which can have a large amount of data collection, real-time transmission, processing and display, etc., four other factors should be considered. The integration of Gas Detector itself adapts to the downhole environment, including factors such as temperature and pressure.

3. Replace the sensor regularly. Taking gas detection as an example, the existing coal mine gas monitoring devices mostly use electrochemical methods, which have very high requirements for chemical components. Generally, the service life of electrochemical components is 2-3 years, and they need to be replaced regularly to ensure the correctness of monitoring information. Once the gas inspectors are not replaced regularly, it is easy to cause safety hazards.
