The parts of the screw air compressor that need to be cooled by water include the cylinder, intercooler, air compressor aftercooler and lubricating oil cooler.
For the cylinder and intercooler, 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 is cut off from 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 properties and cause the moving parts to wear sharply, but also cause the lubricating oil to decompose, and the volatile components in the oil will mix with the air, causing accidents such as combustion and explosion.
For the aftercooler, the air compressor water outage will also cause the aftercooler to lose its cooling effect. In this way, the temperature of the air sent to the air separation unit will increase greatly, destroying the normal working condition of the air separation unit.
For the air compressor lubricating oil cooler, the air compressor water outage will cause the lubricating oil to not be well cooled, and the lubricating oil temperature of the Atlas air compressor will increase. In this way, the viscosity of the lubricating oil will decrease, the lubricating performance will deteriorate, the wear of the moving parts will increase, the machine life will be reduced and the power consumption will increase; in severe cases, the lubricating oil will decompose, and the volatile components in the oil will mix into the air, causing a series of accidents.
In short, cooling is an indispensable part of the operation of the screw air compressor. The air compressor should always pay attention to the cooling water situation. Once the water is cut off, it must be stopped and checked immediately.
