Common faults and treatment methods of rotary vibrating screen
The rotary vibrating screen must be operated according to the instructions during the use of the rotary vibrating screen. It is unforeseeable that the rotary vibrating screen will fail during the long-term operation. The following are some daily failure analysis and treatment methods of the rotary vibrating screen.
The power does not start after the power is turned on. The possible reasons are the short circuit between the stator windings, the short circuit of the stator winding to ground; the overloaded rotor is blocked and other reasons. In this case, it is necessary to check the lines, short-circuit grounding parts and repair them; check the winding wiring and correct them; reduce the load and remove obstacles.
The working principle of the rotary sieve is that the eccentric hammers at the upper and lower ends of the motor drive the three-dimensional motion direction of the motor, and transmit the motion to the screen surface for screening work. After the rotary vibrating screen is started, its power device is the vibration motor. Due to the high-speed placement, a composite inertial force is generated. The inertial force forces the vibrating body of the screen machine to perform a revolving motion, and the screen frame continuously reciprocates under the action of the vibration force, which in turn drives the screen surface to perform periodic motion. Vibration, so that the material on the screen surface moves in a directional and active manner with the screen box, during which, the material smaller than the screen surface aperture falls to the lower layer through the screen hole and becomes the under-sieve material, and the material larger than the screen surface aperture moves continuously after continuous jumping movement. It is discharged from the discharge port, and the screening work is finally completed.
