How to Solve the Problem of Vibration Motor Frequent Trip?

Almost everyone knows the basic operation of vibration motor, but there are some points we need notice in the process of operation,especially the vibration motor frequent trip problem, according to our technical personnel’s experience, now we introduce some methods to avoid the trip for your reference:
1.Capacity unconformity or aging of vibration motor air switch and overcurrent protective device, just change the switch will solve the problem.
2. The wire cable skin of vibration motor is broken ,this is mostly due to wear and tear during long period use,it can be wrapped with tape.
3. Bearing damages or lacks oil,lead to overload trip.Thus we should replace the bearing timely.
4. Vibration motor power supply doesn’t work,or circuit breaker gets aging.
5. The magnetic circuit performance of vibration motor decline,causing too much current.
The above several problems are relatively simple to handle,according to the corresponding reasons, users themselves can solve them through adopting corresponding methods. If the trip of vibration motor is not caused by the above several reasons, please do not hesitate to contact with us,our engineer will solve the problem for you.

How to identify whether there is roller bearing fault or not?

As is known to all, roller is the main part of belt conveyor, while bearing is the precision part of roller, but in the process of using, bearing is the most prone to fail, then how to troubleshoot the problem? It is important to improve the productivity and economy if it can be identified and predicted by the not removal of the bearing in the operation.

First of all, we can judge whether there is failure by sound, but this requires operators with rich experience and rigorous training to identify there is bearing noise;
Then, it can be judged according to the equipment temperature . There are some limitations of this method, we need to record temperature changes to determine whether the bearing fault or not only in the operating state;
Finally, when lubricate the bearing, we can also judge bearing whether there is fault or hidden trouble from dirty lubricant, if it is mixed with foreign matter ,other metal powder or dust, the bearing is bound to a fail.

What Factors Lead to Inflexible Rotation of Conveyor Roller?

In our daily use of conveyor roller, inflexible rotation phenomenon may occur during the operation, what factors lead to inflexible rotation of conveyor roller? Let’s see the following two parts:
The manufacturing quality of belt conveyor idlers
The manufacturing problems of belt conveyor mainly are bearing lacks of rigidity, difficult to ensure the roller assembly accuracy , which restricts the operation flexibility.
Sealing, lubrication and maintenance
Because of belt conveyor working environment is relatively poor, generally, operation site is full of dust, and the bearing sealing form has big influence on roller operation flexibility. If sealing poor, dirt can easily enter into the bearing inner which causes inflexible rotation; in addition, if bearing grease adopts common calcium base grease ,it is easy to change color and become dry, can't reach a very good lubrication effect.

Solutions for Belt Conveyor Roller Inflexible Rotation

As an important part of the belt conveyor,roller plays an important role in the process of conveying.During the operation, the belt conveyor roller may be inflexible rotation when conveying the material.In order to keep the conveyor belt roller running better,here,PK Machinery would like to introduce the handling methods as follows.
Firstly,you should ensure the accuracy of specified requirements during conveyor roller manufacturing process.
1.The precision stamping and the inner hole of the bearing should reach three.
2.The dimensional tolerance,coaxial degree and ovality of the pipe body two ends must conform to the national standard,can not exceed the tolerance. 
Secondly,you should ensure the good sealing and enough lubrication.
In addition to ensure the quality of manufacturing, it also should be with good lubrication materials, such as lithium base grease which can improve the bearing lubrication and prolong the service life of the roller is necessary.
Bearing pedestal uses labyrinth seal structure of radial ball bearing supporting and plastic sealing ring, which can guarantee work roller reasonable force, while good dust effects, resistance, and easy assembly and maintenance, can effectively reduce the transport machine operating costs.
