招远市金凤黄金选矿设备制造有限公司
The normal operation of the flotation machine is an important factor in ensuring the processing capacity and flotation indicators. However, some faults often occur during the operation of the flotation machine. If these faults are not dealt with promptly, they will cause huge economic losses to the mineral processing plant. Below is a brief introduction to common faults during the operation of the flotation machine and their treatment methods. 1. Bearing overheating, or abnormal sounds from the bearing during operation. Causes include: ① Insufficient lubricating oil, or poor quality lubricating oil, resulting in inadequate lubrication of the bearing. ② Excessive wear of the shaft sleeve, leading to cracking. Corresponding fault treatment methods are: ① Add lubricating oil in time, increase the amount of lubricating oil, replace poor quality lubricating oil, or heat the lubricating oil before adding. ② Replace the worn bearing promptly.

Motor overheating and increased phase current. Causes include: ① The motor cover plate or slurry return pipe has fallen off. ② The motor is operating in single-phase mode. ③ Excessive accumulation of ore sand in the flotation machine tank or overly high slurry concentration. ④ Wear of the flotation machine shaft. ⑤ The installation height of the main shaft pulley and the motor differs. Corresponding troubleshooting methods: ① Reinstall and secure the cover plate and slurry return pipe. ② Repair the motor. ③ Clean the ore sand in the tank and adjust the slurry concentration in time. ④ Replace the worn shaft. ⑤ Adjust the installation height of the main shaft pulley and the motor to ensure they are on the same horizontal plane.
