Air compressor is one of the main mechanical power equipment of many enterprises, and it is very necessary to maintain the safe operation of air compressor. Strict implementation of air compressor operating procedures not only helps to prolong the service life of air compressors, but also ensures the safety of air compressor operators.
A. Before the operation of the air compressor, the following issues should be paid attention to:
1. Keep the lubricating oil in the oil pool within the scale range, and check that the oil volume in the oil injector should not be lower than the scale mark value before the air compressor is operated.
2. Check whether the moving parts are flexible, whether the connection parts are tight, whether the lubrication system is normal, and whether the motor and electrical control equipment are safe and reliable.
3. Before the air compressor is operated, check whether the protective devices and safety accessories are intact and complete.
4. Check that the exhaust line is unblocked.
5. Connect the water source and open each inlet valve to make the cooling water unobstructed.
B. When the air compressor is operated, it should be noted that before starting for the first time after long-term shutdown, the car must be checked to check whether there is any impact, jamming or abnormal sound.
C. The machinery must be started in the no-load state, and the air compressor must be gradually put into load operation after the no-load operation is normal.
D. During the operation of the air compressor, after normal operation, the readings of various instruments should be paid attention to and adjusted at any time.
E. During the operation of the air compressor, the following conditions should also be checked:
1. Whether the temperature of the motor is normal, and whether the readings of each meter are within the specified range.
2. Whether the sound of each mechanism is normal.
3. Whether the suction valve cover is hot and whether the sound of the valve is normal.
4. Whether the various safety protection equipment of the air compressor is reliable.
F. After 2 hours of operation of the air compressor, the oil and water in the oil-water separator, intercooler and after-cooler need to be discharged once, and the oil and water in the air storage barrel should be discharged once per shift.
G. When the following situations are found in the operation of the air compressor, the machine should be stopped immediately, the cause should be identified, and it should be eliminated:
1. Lubricating oil or cooling water.
2. Sudden increase or drop in water temperature.
3. The exhaust pressure suddenly rises and the safety valve fails.
The operating power part of the press must be carried out in accordance with the relevant regulations of the internal combustion engine.
