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.

The Difference between Tapered self-aligning roller and Friction self-aligning roller

Tapered self-aligning roller is similar with Friction self-aligning roller in structure which are mentioned when introduce the belt conveyor, their purpose is protecting belt and preventing belt deviation. However, in the process of actual use, there is a big difference between them.
The main difference:

Tapered self-aligning roller

1.Stability performance: these two kinds of roller have their own advantages and disadvantages. Tapered self-aligning roller provides a more stable transport environment for belt and material, but since the tapered roller with a certain angle, if carries the material for a long time, it will increase the radial offset of roller. While friction self-aligning roller has a stable structure so that it can carry material for a long time and won’t be influenced. but there is a certain angle between belt and roller due to design of friction pulley, the joint degree of friction self-aligning roller is lower than tapered self-aligning roller, which will reduce the stability performance of belt conveyor.
2.Friction coefficient: concerning this aspect, tapered self-aligning roller has advantage over the friction self-aligning roller, tapered self-aligning roller has a special body design of roller, it could extremely increase joint degree of belt and roller to make the belt adapt to tapered roller, it also greatly reduce the force of friction.

Friction self-aligning roller

3.Sealing Performance: the sealing performance of friction self-aligning roller is better than tapered self-aligning roller, the friction one adopts the design with independent installation of the friction pulley to promise a good sealing performance, however, because tapered self-aligning roller has a different diameter of pipe, it increase the difficulty of seal, meanwhile, performance of seal is also reduced.
4.Production cost: the structure and technology of tapered self-aligning roller are much simpler, so the cost is low, but if in the long run of using, the friction self-aligning roller is more stable and durable.

How to solve the problem of DC motor abnormal sound？

How to solve the problem of DC motor abnormal sound？

There are many kinds of DC geared motor common fault, here I will talk about it when a failure in the problem of sound, this is also one of the most common problems, why there is a different ring and how to repair?

If there is no axial channeling dynamic collision caused by the armature, should be a structure have loose phenomenon. Everyone please remember a principle: The pole on the gasket shouldn’t be got rid of more often, this will affect the motor performance and running state, about the problem of noise here is the following method: open the electric control system of the motor power supply access oscilloscope waveform is there lack of wave head, lacks can produce vibration and noise, then check the compensation coil and armature connection, if failed it may be the magnetic circuit is too strong, electromagnetic noise, you can put the motor to at the rated speed, to see whether there is in a certain range, and then cut off the power supply. Then to see whether there are noise in the process of slowing down, if not that is electromagnetic noise can be determined, if not it should be mechanical issues.

So, we in the future when using gear motor, ensure that every time it is in the correct operation, also we can't forget the more at ordinary times of maintenance, it is a good way to prevent or reduce the problem.
