In the application of flotation machine in the sorting plant, due to the complicated structure of the flotation machine itself, there are often errors in the process of installation and debugging that affect the flotation efficiency of the flotation machine, and thus affect the work schedule and final selection quality of the entire concentrator, so the installation and debugging process is required to be very rigorous.
So what faults will flotation process have in the flotation machine in the installation and debugging ? What are the precautions?
Common fault one: flotation machine stirring mechanism problem
As the core part of flotation machine, stirring mechanism is directly related to whether flotation machine can function normally. After some parts of the flotation machine are replaced, sometimes the stirring mechanism is not flexible or even cannot run, or the motor bearing temperature is too high in the process of running, abnormal vibration, noise and other problems. These problems are usually interrelated and can lead to motor burn, bearing damage and other consequences if not addressed in a timely manner.
Note: when the flotation machine is first installed, the foreign body in the tank should be removed first. Verify the flexibility of the large pulley by hand to ensure proper belt tension. After checking whether the belt is rotating in the right direction (looking down clockwise) and whether there are any scratches, then officially start. If the above problems occur during the operation of the flotation machine, the belt should be removed, the stirring part should be disconnected and checked separately.
Common fault two: flotation machine scraper mechanism problem
The scraper mechanism of flotation machine is located on the two sides above the tank body of flotation machine. In the process of installation and use, there are often scraper mechanism shaft rotation is not flexible, shaft off, high machine temperature, motor deceleration and reducer oil leakage faults.
Notes: before installation, please check whether the parts of scraper mechanism (such as bearing, coupling, etc.) are damaged, especially whether the scraper shaft is bent or deformed. Since the flotation machine is a scraper mechanism when the head shaft and reducer are usually together, field installation should first unscrew the head shaft and reducer coupler, and then install, to ensure the flexible rotation of the scraper shaft.
Common fault three: flotation machine slot problem
Water leakage is the main fault of the tank of flotation machine. When the flotation machine is installed, the connection surface of each tank body, especially the position of the anchor may appear different degrees of water seepage and leakage, sometimes the bottom of the groove individual weld will also appear this situation. Water leakage does not have much effect on the use of equipment, but will affect the surrounding environment.
Note: when connecting the surface of the groove, the rubber should be kept intact and not deformed. At the same time, the flange should be filled with sealant to seal and strengthen the sealing function. After the joint surface is well connected, pretighten the bolt. When the slot clearance leakage problem occurs, first of all, should check whether the bolt is loose, rubber is damaged, try to relax the pre-tightening bolt, the bolt and rubber or repair interval place again filled with sealant.
Common fault four: flotation machine gate problem
Gate structure is simple, located in the tail of flotation machine, its main function is to adjust the level of the tank. In the process of installation and debugging, the gate is often used, so it is easy to break down the handwheel and run out of water.
Note: first check the lubrication of the screw and the integrity of the rubber, if there is no problem, then pay special attention to the important special screw pre – tightening. Glue the rubber on the back of the gate to make sure it is firm and flat, and install the gate when dry enough.
The above is a few notes about the flotation machine in the installation and debugging and common problems. Want to flotation machine normal and efficient operation, the purchase of high quality flotation machine is on the one hand, but also pay attention to the installation and debugging process in all kinds of details, it is recommended to find a factory with the overall qualification of equipment manufacturers to buy flotation machine, to appoint professional personnel to install and debug the flotation machine, so as not only to ensure the high quality of the flotation machine, but also to prevent the flotation machine caused by mistakes in installation and debugging.
