Everyone should know the common problems of large-scale vibration vibration motor in use. The vibration of the vibration vibration motor is because the vibration vibration motor is equipped with a set of adjustable eccentric blocks at both ends of the rotor shaft, and uses the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block. Get the exciting force.
Then, the larger the vibrating chamber wall vibrator motor, the greater the excitation force, and the stronger the damage to its own vibration. For large-scale vibration vibration motors, ordinary bolts can no longer completely fix the connection of various parts of the vibration vibration motor, and the phenomenon of wire loss easily occurs. Produce uneven vibration.
Large-scale vibration vibration motors are mainly based on 6-level vibration motors, with low frequency and high amplitude. High-frequency vibration vibration motors are mainly small and medium-sized vibration vibration motors, so use the inertia motor when the manufacturer chooses the vibration motor. If a large-scale vibration motor with a relatively fast frequency is required, it is recommended to use several medium-sized vibration motors to improve the vibration force.
1 After starting, the vibration motor does not start, you should check:
2 Whether the power supply lacks phase;
3 Whether the vibration motor is out of phase;
4 Whether the protective cover is damaged and rubs the eccentric block;
5 After starting up, the vibration motor is noisy and generates heat, etc., should be checked:
6 Whether the roughness of the contact surface between the vibration machine and the vibration motor’s foot meets the installation requirements;
7 Whether the anchor bolts are tightened;
8 Whether the vibration acceleration of the main engine meets the requirements for the use of the silo wall rapper;
9 After adjusting the eccentric block, the amplitude changes abnormally. You should check: Whether the eccentric block at both ends of the rotating shaft is adjusted symmetrically;
10 In the vibration equipment with two vibration vibration motors working at the same time, when the phase rotation does not meet the requirements, the phase sequence of the single unit must be adjusted, and the phase sequence of the total power supply of the two vibration vibration motors must not be adjusted.
