5 methods to solve vibration motor frequent trip problem

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.

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.

 

How to solve inflexible rotation problem of conveyor roller?

To ensure accuracy during conveyor roller manufacturing process 
Such as the inner hole precision of punch bearing housing should reach grade 3, dimensional tolerance,coaxial degree and ovality of the pipe body two ends must conform to the national standard,can not exceed the tolerance.
Sealing and lubrication
in addition to ensure the quality of manufacture, also require better lubrication materials, such as lithium base grease which can improve the bearing lubrication performance, this is very necessary to prolong the service life of roller.
Bearing seat adopts labyrinth seal structure of centripetal ball bearing supporting and plastic sealing ring, which can guarantee reasonable bearing stress of roller during operation,but also ensure good dust prevention effect, small resistance, and convenient installation and easy maintenance, it can effectively reduce the conveyor operation cost at the same time. 

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.

Belt conveyor roller has the highest quantity and is the most carrying parts of belt conveyor. Impact roller, friction centering carrier roller, belt conveyor roller, and so on are included. It plays the main role to support the belt conveyor and the weight of material, so the conveyor belt works smoothly. Here PK Machinery will show you a better understanding about it.Hope the following video will help you.

This video show that the conveyor belt Idler is mainly composed of steel pipe, shaft, bearing, bearing block, labyrinth seal, etc.It is the complete manufacturing equipment for conveyor belt rollers/idlers in our factory.How much do you know the working of the conveyor belt roller?Here the video will show you the processing of conveyor belt roller.Wish it can help you have a better understanding.

The daily Care and Maintenance of Motorized Pulley

The daily Care and Maintenance of Motorized Pulley

Are you in trouble with maintaining and repairing motorized pulley when operate the belt conveyor? Come and check this article ,we are sure you will get a satisfied solution ! 
1. In order to create a good condition for normal operation, please check the surrounding environment, fastening bolts, oil leakage, the cable before each start-up.
2. Please start a new pulley with inching running, then it will turn into normal gradually, please check the machine vibration, noise, and temperature heating of each operating component after running for 10 minutes.
3. If oil leakage happens to motorized pulley, please pay attention to check two parts: one is oil seal, check it whether has wear and tear or deformation phenomenon, if any, please replace the cage oil seal timely; the other one is that the air outlet can’t be blocked, if there is blockage, the deposition of dust, grease and sundries shall be removed as soon as possible to ensure smooth access.
4. Regularly check the oil level in the drum is an important part of the daily maintenance, besides, regulation of the oil level height is one of the conditions to ensure the normal operation of the pulley. Inspection methods can be referred according to operation manual.

What Should Users Notice before Running the Motorized Drum with Anti-reverse

Recently, we received a feedback from our Thailand client that the motorized drum with anti-reverse of belt conveyor didn’t rotate, here PK Machinery will explain the notice we should note which can avoid this problem effectively:
1.After installation of the whole set belt conveyor, we should check the motorized drum carefully before commissioning, check and make sure the power supply must be identical to the one stipulated by the nameplate.
2.If the motorized drum with anti-reverse, the wires connection must rotate according to the indicated rotate direction.

 

 3.Check if the oil level of the drum body is satisfied before running. The methods are suggested as below: 
Rotate the drum body, keep the oil outlet as high as 2/3r, see the following figure, then remove the plug and make sure the oil surface is level with the outlet.
(This is important, if without oil, the motorized drum will occurs much noise, even not rotate, and finally it will damage)
