Air compressors are the basic products of industrial modernization. The commonly mentioned electrical and automation have the meaning of full pneumatics; and air compressors provide air source power and are the core equipment of the pneumatic system. They are the main body of the electromechanical air source device. They are devices that convert the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy and are compressed air pressure generating devices.
Air compressors are one of the main mechanical power equipment of many companies. It is very necessary to keep air compressors in safe operation. Strictly implementing the operating procedures of air compressors not only helps to extend the service life of air compressors, but also ensures the safety of air compressor operators. Let's take a look at the operating procedures of air compressors.
1. Before operating the air compressor, you should pay attention to the following issues:
Keep the lubricating oil in the oil pool within the scale range. Before operating the air compressor, check that the oil level in the oiler should not be lower than the scale line value.
Check whether each moving part is flexible, whether each connection part is tight, whether the lubrication system is normal, and whether the motor and electrical control equipment are safe and reliable.
Before operating the air compressor, check whether the protective devices and safety accessories are intact.
Check whether the exhaust pipe is unobstructed.
Connect the water source and open the water inlet valves to make the cooling water unobstructed.
2. When operating the air compressor, pay attention to the first start after a long period of disuse. You must check the wheel to see if there are any collisions, jams or abnormal noises.
3. The machine must be started under no-load conditions. After the no-load operation is normal, the air compressor can be gradually put into load operation.
4. When operating the air compressor, after normal operation, you should always pay attention to the readings of various instruments and adjust them at any time.
5. During the operation of the air compressor, you should also check the following conditions:
Whether the temperature of the motor is normal and whether the readings of each meter are within the specified range.
Whether the operating sound of each machine is normal.
Whether the suction valve cover is hot and the sound of the valve is normal.
Whether the various safety protection devices of the air compressor are reliable.
6. After the air compressor is operated for 2 hours, the oil and water in the oil-water separator, intercooler, and aftercooler must be discharged once, and the oil and water in the air storage barrel must be discharged once per shift.
7. When the following situations are found during the operation of the air compressor, the machine should be stopped immediately, the cause should be found out, and it should be eliminated.
Lubricating oil or cooling water is cut off.
Water temperature rises or falls suddenly.
Exhaust pressure rises suddenly, and the safety valve fails.
