Precautions for installation and maintenance of BKGR wall-mounted explosion-proof air conditioners and principles of explosion-proof
①The installation of explosion-proof air conditioners is unqualified, and the maintenance is not timely. The installation of the air conditioner does not comply with the regulations, which is prone to accidents. The metal shell of electrical equipment such as air conditioners does not have a grounding device. Although there is a grounding device, the electric power is too thick or the grounding wire and the terminal have to be firmly connected or welded together; change the power cord at will, the wiring or the insulated wire is broken Leather, the live part of the air conditioner is exposed; use unqualified electrical products (such as online lines, sockets) for installation; the installer is not a professional electrician or lacks general knowledge of electrical safety. ≯Unable to understand the technical requirements of electrical installation, etc., resulting in poor installation quality, unfavorable maintenance and overhaul, causing stability or danger. Electric shock may occur.
Electrical equipment includes lines, air conditioners, switches, sockets, etc. After a long time of use, there will be insulation aging, switch failure, and even component damage. If you do not repair or replace it in time, accidents may continue to occur if you continue to use it.
â‘¡ Pay attention to poor safety awareness during work. Some electricians are paralyzed at work, have a weak sense of responsibility, and do not strictly abide by the safety operation regulations, resulting in electric shock. For example, when the line or air conditioner is working, the repair is started without electrical inspection; or when repairing the air conditioner, if the power light of the air conditioner is not lit, it is thought that the power supply is cut off and the electric shock will occur when repairing. accident.
After the aluminum alloy explosion-proof material is placed in the explosion-proof air conditioner, because the mesh in the explosion-proof material stack forms a honeycomb structure, the inner cavity of the container is divided into many small "small compartments". At the same time, this honeycomb structure has a high surface efficiency per unit volume, which has excellent thermal conductivity, and can quickly absorb most of the heat released by the combustion, so that the final temperature Tf after the combustion reaction is greatly When it is lowered, the expansion of the reaction gas is greatly reduced, and the pressure value of the container is not increased.
