What to do if the bolt of vertical vibration motor is loose? I believe many friends are upset about this. Therefore, today I will tell you how to maintain the vertical vibration motor bolts.

Because of the special structure of the vertical vibration motor, the exciting force generated by the eccentric blocks at both ends of the motor impacts the anchor bolt 2000 times per minute. Due to the vibration parameters of the vertical vibration motor, the foundation bolt is very easy to loose. Once a bolt is loose, it will cause other bolts to loosen or even break in a short time, thus burning the motor.

In order to avoid the loosening of the foundation bolts of the vertical vibration motor, it is necessary to tighten the anchor bolts frequently and check them frequently. Secondly, the anti loosening device should be added to ensure the good contact between the foot surface and the bottom plate of the vertical vibration motor, so as to make the stress of the foundation bolts uniform.

In terms of material selection for foundation bolts of vertical vibration motor, it is necessary to use the vertical vibration motor with shell and base as an integral whole (i.e. the ground foot surface is on the shell), because the ground foot surface is processed at one time, it can ensure its level. However, due to the existence of assembly error, it is not easy to ensure the level of the ground base surface. In this way, the stress of several anchor bolts is not easy to be uniform, and the bolt with greater force is easy to loosen, which will cause the loosening and fracture of other bolts and burn the motor.

Maintenance of vertical vibration motor
1. Remove the dust in the case regularly to achieve the purpose of heat dissipation, but do not wash with water.
2. Before installation, check whether the fixing bolt hole matches the base bolt hole
3. After installation and commissioning, stop the operation after running for 2-4 hours, check whether all parts are normal, and then tighten the firm bolts on each part.
4. At the beginning of the vertical vibration motor installation, please tighten the bottom hole screw once a day, and then check it every two weeks

5. When the altitude and ambient temperature meet the requirements, the temperature rise limit of stator winding of vertical vibration motor is 80 ℃, and the allowable temperature of bearing shall not exceed 105 ℃

6. During the operation of the vertical vibration motor, attention must be paid to the lubrication of the bearing. Under normal operation conditions, the vertical vibration motor has been running for about 1600 hours. Proper amount of lubricating oil should be injected from both ends of the nozzle. Before oiling, please clean the bearing, bearing chamber and bearing gland.
7. The bearing of vertical vibration motor needs to be lubricated every three months. Usually, the amount of oil added is half of the bearing volume.
