pay attention to the daily maintenance of the vibrating screen

Good use can make the life of equipment and screening efficiency increase exponentially. In the use of vibrating screen, the vibration motor should be regularly protected to ensure the longer life of the motor, and the problems that easily occur during the actual use of the screen are summarized and analyzed as follows. Users can be more convenient for comparison, for better maintenance of equipment. 1, The voltage is insufficient. The material of the screen is too much. Check the circuit, screen the material evenly, and have the allowance in sieving. 2, vibration motor problems, mainly in the installation. Because there is a heavier eccentric block at both ends of the vibration motor, such as vertical or inclined installation, the bearing will bear the polarization force, which has a bad effect on the bearing, and then shortens the service life of the motor. 3, protection cover and seal ring seal problem: the vibrating screen working environment is very bad, dust is big, when the protective cover of the vibration motor is not tight, it is easy to enter the dust. If the seal ring is not tight again, it will lead to the friction work of the pain block, and then burn the motor. 4, the problem of anchor bolts: the loosening of anchor bolts will also cause damage to vibration motors. Due to the shock force produced by the vibration motor at both ends of the vibration motor two thousand times per minute to impact the anchor bolt and the vibration of the vibration motor itself, the anchor bolt is very easy to loose. Once a bolt is loose, the other bolts will be loosened, even cracked, and then burn out the motor in a short time. 5, too much oil or grease injection is one of the main reasons for the damage of vibration motors. 6, the angle adjustment angle of eccentric block is too large, it will produce the vibration of maximum amplitude, it will run under the maximum amplitude for a long time, it will cause the bearing wear to speed up, and the bearing will shorten the life because of fatigue, so the adjustment of the eccentricity should be appropriate, if the vibration quantity is not enough, the vibration motor of the larger one can be replaced so that the operation can be extended. Cycle. 7, Temperature problem. The normal bearing of the bearing should not exceed 75 C. The new vibration motor has a running in process, maybe the temperature is slightly higher, but after a period of work, the temperature should be stabilized. If the stability continues to be too high, the level of oil, the level of oil and the cleanliness of the oil should be examined.
