Precautions before operating the screw air compressor

1. Before operating the air compressor, the following issues should be noted:
a. Keep the lubricating oil in the oil pool within the scale range. Before operating the air compressor, check that the oil level in the oil injector should not be lower than the mark value.
b. Check whether each moving part is flexible, whether each connecting part is tight, whether the lubrication system is normal, and whether the motor and electrical control equipment are safe and reliable.
c.Before operating the air compressor, check whether the protective devices and safety accessories are intact and complete.
d. Check if the exhaust pipeline is unobstructed.
e. Connect the water source, open each inlet valve, and ensure that the cooling water is unobstructed.
2、 When operating the air compressor, attention should be paid to whether there is any collision, jamming, or abnormal noise before starting the compressor after long-term shutdown.
3、 The mechanical bi must be started without load, and gradually put the air compressor into load operation after the no-load operation is normal.
4、 When operating the air compressor, after normal operation, attention should be paid to various instrument readings and adjustments should be made at any time.
5.During the operation of the air compressor, the following conditions should also be checked:
a. Whether the temperature of the motor is normal and whether the readings of each electric meter are within the specified range.
b. Check if the running sound of each component is normal.
c. Check if the suction valve cover is heating up and if the valve’s sound is normal.
d. Is the various safety protection equipment of the air compressor reliable.
6、 After operating the air compressor for 2 hours, the oil and water in the oil-water separator, intercooler, and aftercooler should be discharged once, and the oil and water in the air storage bucket should be discharged once per shift.
7、 When the following situations are found during the operation of the screw air compressor, the machine should be stopped immediately, the cause should be identified, and eliminated.
a. The lubricating oil or cooling water is ultimately cut off.
b. Sudden increase or decrease in water temperature.
c. The exhaust pressure suddenly increases, causing the safety valve to malfunction.
