As the most common equipment in the factory, air compressors must pay special attention to maintenance and inspection.

　　Common air compressor fire causes:

　　1. The air compressor is not thoroughly maintained. The joints and pipe fittings in the oil circuit system leak and cause a lot of oil inside the machine. When the electrical components are short-circuited and caught fire, the oil pollution will aggravate the combustion and easily cause an explosion.

　　2. The filtering effect of the air filter is not good, and the dust content in the air is large and it is easy to form carbon deposits; the adsorption effect of the molecular sieve is reduced, so that the hydrocarbons enter the subsequent rectification tower, and the excessive accumulation may cause an explosion accident;

　　 3. The oil injection pump or the lubricating oil system is malfunctioning. The failure of the air compressor oil injection pump or the lubricating oil system can lead to insufficient or interrupted lubricating oil supply, and the quality of lubricating oil can lead to poor lubrication effect, mechanical friction and heat generation of the compressor, which becomes the ignition source of the fire and explosion of the air compressor system.

　　 4. The cooling water system is faulty. The cooling water of the air compressor is interrupted, the water supply is insufficient or the water temperature is too high. The cooling effect is not good. The temperature in the compressor is too high, which causes the thermal cracking of the lubricating oil. Carbon deposits are formed at the reactors and buffer tanks. Carbon deposits are a kind of flammable substance, which can cause spontaneous combustion of carbon deposits under high temperature and overheating, mechanical impact, airflow impact, and produce carbon oxides (such as CO, etc.). When the concentration reaches the explosive limit At times, combustion and explosion will occur.

　　 Preventive measures for air compressor accidents:

　　 1. The air compressor and its associated storage tanks and piping systems should be designed in accordance with the relevant national design specifications. A dry filter should be installed before the suction pipe of a large air compressor.

　　2. After the air is compressed, the temperature rises sharply, and the air compressor must be equipped with an effective cooling system. The cooling water system of large air compressors must be sensitive and reliable with water cut-off protection devices. If the water supply is interrupted during operation, forced water supply is strictly prohibited, and it needs to be stopped for treatment.

3. The design and operation of the air storage tank should comply with the "Pressure Vessel Safety Technical Supervision Regulations". The necessary pressure display and overpressure adjustment and alarm systems should be installed. If conditions permit, the air compressor e assistant can be installed to monitor from time to time. Various data of air compressor.

　　4. Large-scale air compressors should be equipped with surge, vibration, oil pressure, water supply, shaft displacement and bearing temperature alarm interlock devices according to the characteristics of the equipment. An airdrop test should be done before driving.

　　5. If the air compressor is running, if there is an abnormal sound, stop immediately and check and deal with it.

　　6. ​​In the process of high-speed air flow, rust and mechanical impurities may become hot sparks. Therefore, the position and height of the air inlet during the operation of the compressor should meet the safety requirements to prevent foreign matter from entering.

7. Air with a certain pressure is highly oxidizing. Therefore, during the storage and transportation of the air, it is necessary to strictly prevent lubricating oil and other organic substances from mixing into it, so as to prevent the oil and other organic substances from being oxidized and burning in the system. Or explosion etc.
