Flammable gas detectorsThe application of the device in security and environmental detection is becoming more and more widespread. Many industrial enterprises are applying them to protect safe production. In this process,flammable gas alarmThe installation and use of the Otherwise, even if it is installed, it will not get a good security monitoring function. The specific installation method is as follows:
1.There are many types of flammable gas. Different flammable gases have different molecular weights. Therefore, it is particularly important to choose the right mounting position in relation to the air. In general, we should pay attention to several principles. If the molecular weight is less than the air ratio, it should be installed high in the roomflammable gas alarm。 Due to the light proportion of gases, it needs to be installed high in the room, for example, hydrogen. When there is a gas heavier than air, it usually accumulates after leakage, so it is chosen to be installed at a height of about 30-50cm above the ground. If the specific gravity is the same as that of air, the installation position can be at the same height as the leak source. The above are the main onesflammable gas alarmheight selection and installation.
2. In principle, the installation location should not be close to the window or air outlet, and in principle, the gas collection place and leakage source should be selected.
3.flammable gas alarm,toxic gas alarmThe installation of other equipment generally adopts explosion-proof galvanized pipe threads, and the electrical connection port at the instrument end generally adopts explosion-proof spoiler pipes, and the electrical thread size is M20.
4. It is generally recommended to use three-core shielded wire wiring, and the power cable is separated from the weak wire duct. If a digital means of communication is required, shielded twisted pair wires should be used on the wires. In addition, the thickness of the steel wire can be considered 0.3-0.5mm2 single strand core. The power consumption of such instruments is low. If the wire is too thick, it is a waste.
5. In terms of monitoring, there is an integrated sound and light alarm and remote monitoring mode. Relatively speaking, the on-site sound and light integrated alarm is simple to install and remoteGas alarmGenerally, it needs to be installed in a manned duty room, and once there is danger, it can be known immediately. There is also a combination of these two monitoring modes. In addition, with the development of industrial informatization, many intelligent monitoring methods have emerged.
