How to Conduct Proper Inspection of Flammable Gas Detectors?
The essential combustible gas detector in safety production is an important alarm device that can quickly detect the presence of combustible gases in the air and whether the gas concentration has reached the explosion limit, which can prevent explosion accidents at critical moments. Although it is so important, there are still many users who do not know how to do a good job in the inspection of combustible gas detectors.
1. Conduct a power check on the combustible gas detector
Combustible gas detectors typically use batteries or accumulators, and the required power for the machine is clearly specified in the machine manual. Before verification, it is necessary that the power supply provided by can meet the normal operation of the machine.
The main components of an alarm are sensors and sampling pumps. Under normal working conditions, the two parts require relatively large currents to heat the sensor to a sufficient temperature, and the final sampling flow rate can be fully utilized. If there is insufficient power, the standard gas indication is low; If the sampling volume is small and the response time of the instrument for measuring standard gases is too long, it will have a significant impact on the accuracy of the indication. Therefore, if you want to use batteries or removable batteries, first adjust the power supply.
2. Check the various information and operation of the measuring instrument
From the inspection of measuring instruments, the first step is to check the appearance of the combustible gas detector and whether the surface is clean; Also, carefully inspect the appearance for any damage and any adverse effects on normal operation.
It is also necessary to identify and measure the relevant information of the instrument, such as checking whether the basic information of the machine, including model, name, manufacturer, etc., is correct; Is there any product information related to explosion-proof, including explosion-proof numbers and explosion-proof signs; Is there any license information, including number, identification, etc. It should be clearly displayed on the of the measuring instrument.
Also, the operational status of the measuring instruments should be checked. For example, whether the measuring instrument can operate normally, and whether it can display clearly, completely, and accurately after completion.
