The maintenance and repairment of Flotation machine

Maintenance and repairment of the flotation machine is to ensure the normal operation of the flotation machine during the production, reliable work, stable production, to ensure that the mechanical equipment in a good state of technology, so that some of the flotation machine equipment has strict technical requirements of the site often Keep in the range of allowable material wear.
Flotation machinery and equipment maintenance and repairment need to focus on the following aspects of the work:
(1) According to the regulations, need to do a good job of mechanical equipment operating parts of the lubrication work. For example, the upper and lower bearings of the mixer, the scraper shaft bearings, reducer and so on. Often overlooked is the control of the liquid level of the gate of the screw and umbrella gear, drain mouth screw hand wheel and other less active parts. Poor lubrication may occur motor fever, shaft damage, adjust the failure and inconvenience and other undesirable phenomena.
(2) Should pay attention to check the operating state of the scraper blade. Do not bend the shaft, the bearing cannot sink, the coupling cannot be loosened, scraper blades cannot be short, fixed screws should not be loose, leaves to smooth, edge to maintain the level and so on. The outer edge of each slot must scratch the same depth, cannot meet the technical requirements of the parts must be promptly repaired or replaced.
(3) Flotation speed of the flotation machine is an important technical parameter. To ensure that the flotation machine to achieve the rated speed, the main measure is to make the belt on the triangular belt to achieve the required number, elastic moderate, and the degree of tightness of the V-belt similar. The lack of or less elasticity of the V-belt is an important reason for the insufficient number of flotation blades.
(4) Regular cleaning flotation machine. When the coal slurry contains mud, wood and other debris more, the impeller chamber and overflow surface adjustment gate groove may be blocked by various debris. The parts in the machine room are immersed in the coal slurry for a long time, and the surface is easily covered by muddy sediments, which may lead to the smaller effective volume of the machine room. These may affect the flotation machine work effect, we must promptly clean up.
(5) According to the coal gas filling and stirring and motor load changes, etc., at any time easy to wear parts (such as stator, impeller, injector nozzle, etc.) material wear situation. The undesirable parts must be adjusted or replaced in time to ensure that the flotation machine is operating in good technical condition.
(6) Pay close attention to the work of the motor. There are many reasons for the overheating of the motor bearing pad, such as the bottom slime deposition, the impeller stator clearance is too small, the suction pipe is blocked and the reason of the motor itself. Must be carefully and carefully analyze the reasons to grasp the law of the accident, in order to effectively avoid or reduce electrical accidents.
(7) Flotation machine if there is abnormal vibration and sound, you must stop the inspection process. When the air intake is blocked, it must be cleaned and cleared in time.
Through the maintenance and maintenance of the flotation machine, so that the flotation machine to achieve a good working condition, so as to better harvest.
