During the operation of the air compressor, cooling is an indispensable part. During the operation, inspection and maintenance should be done to ensure the cooling performance and effect of the cooler, so that the air compressor can work under isothermal conditions.
The cooling method of air compressor is divided into two types: water-cooled and air-cooled. For water-cooled air compressors, attention should be paid to the condition of the cooling water. Once the water is cut off, it must be shut down for inspection.
Water-cooled screw air compressors need water-cooled components such as cylinders, intercoolers, air compressor aftercoolers, and lubricating oil coolers.
For cylinders and intercoolers, one of the purposes of cooling is to reduce the exhaust temperature so that the exhaust temperature does not exceed the allowable range. It can be seen that after the screw air compressor loses water, the cylinder and intercooler cannot be cooled, and the exhaust temperature of the air compressor rises sharply. This will not only cause the lubricating oil in the cylinder to lose its lubricating performance and cause rapid wear of moving parts, but also decompose the lubricating oil. The volatile components in the oil will mix with air, causing accidents such as combustion and explosion.
For the air compressor lubricating oil cooler, the air compressor will not be able to cool the lubricating oil well, and the air compressor lubricating oil temperature will increase. In this way, the viscosity of the lubricating oil will decrease, the lubricating performance will deteriorate, the wear of moving parts will increase, the life of the machine will be reduced and the power consumption will be increased, and the lubricating oil will be decomposed, and the volatile components in the oil will be mixed into the air, causing a series of accidents.
The cooling of air compressors is very important, especially water-cooled air compressors. When the air compressor is short of water or water failure, if the fault is not detected and eliminated in time, it will not only seriously affect the performance of the air compressor, but also cause huge damage to the air compressor, reduce its service life, and even cause accidents such as combustion and explosion. happened.
