Operation process of liquefied gas compressor

1. Make sure the belt of the liquefied gas compressor is properly tensioned and the gear is flexible.

2. Confirm that the lubricating oil level is within the allowable range of the dipstick and the color composition of the oil is normal.

3. According to the loading and unloading requirements, confirm that the status of the storage tanks, pipelines and valves are consistent with the process plan.

4. Open the drain valve to drain the condensate in the gas-liquid separator.

5. After receiving the start notification, open the outlet valve of the liquefied gas compressor and press the start button.

6. When the oil pressure is normal (greater than or equal to 0.15MPa), slowly open the intake valve.

7. When the compressor is operating normally, keep the oil pressure greater than or equal to 0.15MPa, and the inlet and outlet pressure difference less than or equal to 0.5MPa

8. When the liquefied gas compressor is running, the operator must not leave the site and must monitor the various instruments of the machine to see if they are stable and the temperature is normal.

9. After receiving the shutdown notice, press the stop button. After stopping, close the inlet and outlet valves.

10. Keep operation and shift handover records in accordance with regulations.

11. Remove the belt guard every month to check the belt wear and whether the pulley positioning is normal. If abnormal, report to the team leader to request repair or replacement.

12. Change the lubricating oil every 3 months.

13. Keep the surface, base and floor of the liquefied gas compressor clean and tidy without dust or oil stains.
