What is the specific process of flotation equipment maintenance?

1. Preparation before maintenance
Develop a detailed maintenance plan, including maintenance time, personnel arrangement, and required tools and materials.
Shut down and cut off the power supply of the equipment, and hang up a warning sign of "Maintenance in progress, no closing".
2. Dissolved air system inspection
Check the appearance of the dissolved air tank for deformation, corrosion, etc.
Open the dissolved air tank and clean the dirt and impurities inside.
Check whether the inlet and outlet valves of the dissolved air pump are normal and whether the seal is good.
Test the operation of the dissolved air pump and check whether the pressure and flow meet the requirements.
3. Releaser inspection
Observe the appearance of the releaser for blockage and damage.
If there is blockage, use appropriate tools to clean it.
Replace the damaged releaser in time.
4. Scraper device maintenance
Check whether the scraper is deformed or worn.
Check the chain and sprocket of the scraper and add lubricating oil.
Adjust the contact angle and depth between the scraper and the liquid surface to ensure the scraping effect.
5. Dosing system maintenance
Calibrate the dosing metering pump and check whether it is operating normally.
Clean the sediment in the dosing pipe and dosing tank.
Supply enough reagents.
6. Flotation tank cleaning
Drain the flotation tank, clean the sediment at the bottom of the tank and the attachments on the wall.
Check the anti-corrosion layer of the tank body and repair it in time if it is damaged.
7. Electrical system inspection
Check whether the electrical circuit is damaged or aged.
Test the insulation performance of the motor to ensure the normal operation of the motor.
Check the electrical components in the control box and tighten the terminals.
8. Equipment sealing inspection
Check the connection of the pipeline and the sealing gasket of the valve, and deal with the leakage in time.
9. Post-maintenance test
After completing the maintenance work, start the equipment for trial operation.
Detect key indicators such as dissolved air effect, scraping effect, and dosing accuracy.
10. Record and summary
Record the various operations, problems found and treatment methods during the maintenance process in detail in the maintenance file.
Summarize the experience of this maintenance and provide reference for the next maintenance.
