In order to make the flotation machine operate normally and efficiently, in addition to normal operation and maintenance, it must be timely repaired, and the faults occurring in the operation of the equipment should be handled and eliminated in time. The common faults and treatment methods of the mechanical agitation flotation machine in operation are shown in the table.

Table flotation machine common faults and treatment methods Fault phenomenon cause of issue Approach Partial liquid surface 1. The impeller and the cover are not installed properly. The axial gap is large on one side, the side is small, and the side with large gap is turned over. 2. The cover is partially damaged by the impeller 3. The steady flow plate is broken. 4. The pipe joint is loose. 1. Adjust the gap 2. Replace 3. Repair 4. Fasten Insufficient inflation or sinking 1. The impeller cover is seriously worn, the clearance is too large 2. The impeller cover installation clearance is large 3. The motor speed is not enough 4. The inflation tube is blocked or the nozzle valve is closed 5. The slurry circulation is too large or too small 1. Replace 2. Re-adjust 3. Check motor speed 4. Clean or open 5. Close small or open circulation hole Insufficient suction or running water in front groove 1. The feed pipe is worn and leaked. 2. The feed pipe is too large, the feed amount is small. 3. The middle chamber is blocked by coarse sand. 4. The contact between the mine pipe and the groove wall is not good (the gasket is damaged and the screw is loose). 1. Replacement 2. Partial blockage of the mine pipe 3. Water pipe flushing 4. Repair The intermediate chamber or the discharge bin does not discharge the slurry. 1. The groove wall wears out 2. The pipe is blocked or loosened 3. The impeller cover is damaged 1. Repair 2. Overhaul 3. Replacement Liquid level can't be adjusted 1. The gate screw is tripped, the bottom of the gate is perforated or rusted. 2. The gate is over-adjusted (reverse misalignment) 1. Replacement and repair 2. Gate reset The suction groove has a large amount of scraping, and the DC slot cannot be scraped out. Mostly because the DC slot does not open the circulation hole gate turn on Concentrate trough If the dose is appropriate, the pipe is blocked. dredge The spindle is not up and down properly. 1. Ball bearing damage 2. The impeller mass is unbalanced, the spindle swings, and the impeller cover collides 3. The cover is damaged 4. The foreign object falls into the slot 5. The spindle top cover is loose 6. The impeller cover gap is too small 1. Replacement 2. Inspection 3. Replacement 4. Removal 5. Fastening 6. Retuning Bearing heating 1. Bearing damage, ball rupture 2. Lack of lubricating oil or poor oil quality 1. Replace 2. Add, change oil Spindle pulley swing and bracket swing 1. The pulley is not installed properly. 2. The bracket bolt is loose. 3. The seat plate is not padded. 4. The impeller is uneven in mass. 1. Reloading, adjusting 2. Fastening 3. Padding 4. Replacement The motor is hot and the phase current is increased. 1. Excessive sand accumulation in the tank 2. Shaft damage 3. Cover plate and loosening of the mine pipe 4. Wear of the mine pipe, excessive circulation 5. Air cylinder wear through, excessive circulation 6. Motor single phase Running 1. Dosing, sanding 2. Replacement 3. Tightening 4. Replacement 5. Replacement 6. Overhaul
