Mid-december, the cause of the vibration motor running from time to tome noise and disposal methods

1. Vibration motor change extremely rewind, improper slot coordination: to check the stator and rotor slot coordination; 2. Vibration motor rotor friction insulating paper or slot wedge: cut slot wedge insulation paper or maintenance; 3. Vibration motor bearing wear or rendering problem: repair or change new bearing; 4. Vibrating motor stator and rotor be loose: check vibration reasons, to kill the heart stop disposal; 5. Vibration motor voltage is too high or three-phase voltage imbalance: measurement of the power supply voltage, and check the voltage too high or the cause of the unbalanced; 6. Vibration motor stator winding wrong: check the wiring diagram, will end when heated to the correct connection connected ( Including banding, insulation disposal and paint) ； 7. Breath is not the average vibration motor, settle, rotor friction each other; 8. Vibrating motor rewind the number of turns per phase are not equal: wound again and correct the number of turns; 9. Smooth bearing short fat: cleaning bearing, to participate in appropriate smooth fat, make its filled with 1/2 ~ 1/3 of bearing housing net volume; 10. There was something wrong with vibration motor winding ( Such as short circuit) Will break area heated to the temperature of the insulation class is allowed, to soften paint and then break up, with the same specification filter operator safe operating procedures: vibrating screen points are divided into the following four: a vibration motor, before work should check the sieve filter of fasteners, connecting pieces, vibration of the wheel and the tension spring ever loose and crack, such as electrical maintenance line should be in good condition. Of powder dust installation, ventilation installation after the static inspection, then stop the test run. Second, in the work, found that the clutter needs to pay screen, must cut off the power supply, reoccupy tools to clean up. If the operator needs to enter within the tao screen, it is necessary to set people care. Three ZG405 vibration motor, ventilation, dust removal installed in powder, granule grading vibration and the process of slag discharge, must adhere to in good condition. Leakage should be timely repair if present, shall not take a disease. Shale shaker points filter should avoid splash or run pulp slurry, influence the working environment, should be timely repair. A small amount of mud and powder leakage to the channel should be clear at any time. Four, abide by electric porcelain ordinary safe operating procedures. After local repair welding line will be broken, pack good insulation, then through painting, drying treatment. Recently had a customer consultation about the process of the functioning of the warehouse wall vibrator in exciting force is too large, have time to feel to the bin ( Hopper) What is the reason to shatter the? Below I will give you analyze the reason for the common vibration and the solution: 1, silo wall vibrators selection error, model too much cause vibration force is too large. Should adjust the Angle of eccentric block on both ends. 2, unit root, or a fixed instability. Should be back device, fixed flat. 3, rotor imbalance, Such as the rotor weight on the screw is shattered, the eccentric block is not in the center of rotor shaft) 。 Should be corrected dynamic equilibrium. 4, a shaft bending. Should change a shaft, or car straight set ( Heat set) 。 Article 5, cage rotor guide fracture, break or wound rotor winding, when the load current when small oscillation. You should check repair. 6, stator winding has some problem, rotating magnetic field is not balanced and provoked vibration, should check repair.
