a. Keep the lubricant in the oil pool within the scale range. Before operating the compressor, check that the oil level in the oil injector should not be lower than the mark value.
Key Takeaways
- Follow the documented startup and power-down sequence every time; shortcuts cause pressure shocks and wear.
- Keep the compressor room ventilated, clean, and free of combustible material.
- Train operators to recognize abnormal noise, vibration, and warning indicators before they escalate.
Before operating the compressor, the following issues should be noted:
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 dependable.
c.Before operating the 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 guarantee that the cooling water is unobstructed.
2、 When operating the compressor, attention should be paid to whether there is any collision, jamming, or abnormal noise before starting the compressor after long-term power-down.
3、 The mechanical bi must be started without load, and gradually put the compressor into load operation after the no-load operation is normal.
4、 When operating the compressor, after normal operation, attention should be paid to various instrument readings and adjustments should be made at any time.
During the operation of the 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 compressor dependable.
6、 After operating the 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 compressor, the machine should be stopped immediately, the cause should be identified, and eliminated.
a. The lubricant or cooling water is ultimately cut off.
b. Sudden raise or decrease in water temperature.
c. The discharge pressure suddenly increases, causing the safety valve to malfunction.
- Technology configuration
- Strike Cost
- Import and ship assistance
Selection and Sizing Considerations
Follow the documented startup and power-down sequence every time; shortcuts cause pressure shocks and wear. Keep the compressor room ventilated, clean, and free of combustible material. Train operators to recognize abnormal noise, vibration, and warning indicators before they escalate.
Frequently Asked Questions
What should I check before starting a compressor?
Check oil level, condensate drains, inlet filters, belt tension, and that all safety guards are in place.
Why does the machine need to warm up or cool down?
Proper warm-up distributes lubricant, and a controlled shutdown lets the unit depressurize and cool evenly.
How much clearance does a compressor need around it?
Follow the manufacturer clearance for intake, exhaust, and service access, typically at least one meter around the unit.
