What mistakes are often made when installing gas detectors?
A large amount of toxic and harmful gases are produced during the production process of the factory. As an operator at a grass-roots position, while doing a good job of self-protection, it is necessary to strengthen the prevention of toxic and harmful gases, such as installing gas detectors on equipment valves, interfaces and key parts. The use of gas detectors can regularly detect harmful and flammable gases in special areas Gases are detected and recorded. So what mistakes are often made when installing a gas detector?
Common mistakes in installing gas detectors:
1. Blindly install the detector without knowing the characteristics of the gas
This question is a cliché, but some friends still ignore this question.
In order for the gas detector to really work, it is very important to figure out the specific gravity of the air that needs to be detected. Because only by knowing the air specific gravity of the gas, can we confirm the installation height of the gas detector.
After confirming the height of the device, we will find a suitable location for the gas detector according to the distribution of working conditions at the detection site and the possible location of the leak point.
2. The control interval that the gas detector can detect
Many friends have such a misunderstanding that gas detectors, especially fixed gas detectors, can detect a long distance.
In fact, because most of the detectors are scattered, the detector can detect the concentration only when the gas to be detected is dispersed on the sensor head of the detector. Otherwise, even if the space is filled with toxic gas, once it is affected by the air flow direction and concentration ratio, the detector will not be able to sense it.
And about how far to install a gas detector, there is no strict standard. We can only draw conclusions after we fully understand the situation at the site to be tested.
3. Good quality gas detectors can adapt to various complex environments
Under normal circumstances, gas detectors have their own working conditions that they are used to, and they need to pay attention to the basic conditions such as humidity, temperature, and pressure.
Usually, it is more suitable to be installed in the environmental factory building, basically it can be directly installed and fixed, but when we install it in the confined space of pipelines and flues, we must pay attention to understand the working conditions.
Regardless of the brand, the environmental conditions that the gas detector can get used to are the normal temperature of -20 to 50 degrees, the humidity below 90% without condensation, and the pressure within the range of 100kp.
