Air compressor is a common and important equipment, and its work can not be separated from starting oil. Because the air compressor needs continuous operation, especially in hot summer, long-term use will lead to the decomposition of engine oil into carbon deposits at high temperature, which may lead to spontaneous combustion. Spontaneous combustion has a serious impact on the normal production of enterprises, and may also lead to property losses and casualties, so it is very important to take appropriate fire prevention measures.
First of all, it is very important to choose lubricating oil with good oxidation stability, proper viscosity and flash point. This can reduce the decomposition speed of engine oil in high temperature environment. If the air compressor must be used at high temperature, the operating temperature should be controlled below 150℃.
Secondly, it is also the key to fire prevention to remove the accumulated oil and carbon in the cylinder and air passage of air compressor in time. Although the oxidation and decomposition of engine oil can not be completely avoided, the thickness of carbon deposit can be controlled below 3mm by regularly removing oil and carbon deposit in the air passage.
In addition, other factors that may cause spontaneous combustion of air compressor need to be eliminated. For example, make sure that the air compressor is well grounded to prevent sparks caused by static electricity. In addition, abnormal collision and seizure of the moving parts of the air compressor should be avoided, and the parts of the container and pipeline should not be loosened to cause collision. At the same time, non-flammable sealing materials should be used to avoid serious air leakage of the valve and ensure that the piston ring leakage is not too large to prevent the crankcase from overheating.
In addition, in order to prevent the oil in the air from reaching the explosive concentration, we should control the idling of the air compressor and the running time of decreasing the displacement to avoid the rapid increase of the oil and gas accumulation concentration.
In a word, the fire prevention work of air compressor is particularly important in high temperature environment. In addition to the above measures, it is necessary to carry out routine maintenance and maintenance of the air compressor on a regular basis to ensure the normal operation of the equipment. Only by taking effective fire prevention measures can we ensure the safe and smooth production of enterprises.
