1. Check and ensure the fire protection system's power supply and circuits are unobstructed and electrical equipment is in good working order every shift.
2. Perform a pump rotation check every shift. The coupling should be adjusted evenly with light and heavy pressure, without any abnormal noises, and record the results.
3. Check the lubricating oil level in the vacuum suction unit on the 5th, 10th, 15th, 20th, 25th, and 30th of each month. Add oil to the oil level at or slightly below the center line of the oil window. Start the multistage fire pumps, check the water filling time, and record it. Pumps #1 and #2 should run for 15 minutes, and pumps #3 and #4 for 5 minutes.
4. After starting the pumps, check the operation of the float assembly. There should be no water in the exhaust hose. If water is present, the float gasket must be replaced.
5. After starting the pumps, check if the large and small seals of the vacuum suction unit are tight and if the exhaust is normal.
6. After starting the pumps, check the packing seal level. Leakage should not exceed 10-30 drops/minute.
7. Regularly check the lubricating oil in all parts of the pump to ensure the lubrication system is functioning properly.
8. Regularly check all connections for tightness and looseness. If water is present, the float gasket must be replaced.
9. After pump startup, check if the vacuum suction unit's large and small seals are tight and if venting is normal.
10. After pump startup, check the packing seal level; leakage should not exceed 10-30 drops/minute.
11. Regularly check the lubrication oil in all pump parts to ensure the lubrication system is functioning properly.
12. Regularly check all connections for tightness and looseness.
