english Equipment Operation Guide
1. Pre-Operation Preparation and Inspection
- Check connections of all equipment components
- Ensure pipeline valves open freely and are free of leaks or blockages
- Clean debris inside and around the equipment
- Ensure water inlet and outlet are clear
- Check power supply, air supply, and chemical supply
- Confirm control system displays normal operation
- Verify all sensors are securely connected
- Lubricate and inspect transmission components
- Ensure scraper operates smoothly
2. Standard Startup Procedures
- Start chemical dosing device first
- Ensure stable chemical delivery at set rate
- Start dissolved air system after chemical system
- Gradually adjust pressure to specified range
- Observe bubble formation until stable
- Open water inlet valve and control flow rate
- Increase water flow evenly to avoid impact
- Start scraping equipment and adjust frequency
- Match scraping rate to scum formation
3. Parameter Monitoring During Operation
- Observe key parameters in control system
- Monitor pressure and flow in real time
- Ensure operation remains within reasonable range
- Regularly check bubble morphology
- Adjust dissolved air system if bubbles are too large, too small, or uneven
- Monitor thickness and condition of scum layer
- Adjust scraping frequency for timely removal
- Prevent excessive accumulation that affects efficiency
- Test inlet/outlet water quality at regular intervals
- Fine-tune parameters based on test results
4. Important Points for Daily Operation
- Keep equipment area clean and tidy
- Prevent debris from entering treatment system
- Follow specified mixing ratio for chemicals
- Prevent overdosage or underdosage
- Thoroughly clean dosing lines when changing chemicals
- Observe equipment for abnormal noise or vibration
- Immediately stop equipment if abnormalities detected
- Do not disassemble components during operation
- Perform maintenance with power off
5. Standardized Shutdown Procedures
- Close the water inlet valve first
- Continue operating chemical and air systems for adequate separation
- Shut down systems after scum is largely removed
- Shut down scraper, dissolved air system, and chemical dosing in sequence
- Check that equipment is completely drained
- Open drain valve to remove accumulated water if necessary
- Clean equipment and surrounding area after shutdown
- Record operating data and any abnormalities
- Document issues for reference during next startup
Note: Always follow safety protocols and manufacturer guidelines when operating equipment.
Regular maintenance and proper operation ensure optimal performance and longevity of the system.
