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.

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.

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)

The Application and Introduction of Rainproof Cover

In the process of operation,rainproof cover plays an important role in conveyor.It can be widely used in power plants, cement plants, steel plants, chemical plants, coal plant, port, dock, mine enterprises.The following are the application and introduction of rainproof cover which prolong the service life of conveyor during the operation:

 Application

Rainproof is also known as color rainproof cover, conveyor rainproof cover, conveyor dustproof cover etc..Rainproof cover can be widely used in power plants, cement plants, steel plants, chemical plants, coal plant, port, dock, mine enterprises. Rainproof cover has a great effect on the goods and environment. It can reduce the loss and waste of the goods in the transportation.It can ensure safe and reliable of belt conveyor in the transportation. Also, rainproof cover prolongs the service life of conveyor.

TypesRainproof cover has the stationary type, open type and with observation window type. We can know clearly whether the belt conveyor is running or not. The main colors of rainproof cover is blue, black, red and others.

Installation1.As two of the  rainproof cover, stationary type and open type cover are made of galvanized corrugated steel or color coated steel.Generally, in every 10 covers,there are 9 stationary type covers and 1 open type cover. Also, these two covers can be arranged alternately.
2.The framework of fixed belt conveyor is connection angle steel or Z steel, and its length is the same as the  cover of belt conveyor. If it needs to install the support angle steel, we should weld the support angle steel  on both sides of the rack,and then weld  the connection angle steel or Z steel to the support angle steel.
3.When we install the rainproof cover, we should install it from one end to the other end in order. Also,it is forbidden to stand in the rainproof cover and should not hit it.
4. We can fix the rainproof cover in the connection angle steel or Z steel by tapping screws. Each one should more than 4 fixed points.
5.We can install one observation type in every 10 other rainproof cover in order to examine or maintain.  

Common Failure Diagnosis and Troubleshooting of Motorized Pulley(1)

The motorized pulley should be checked regularly and eliminated trouble timely. The common failure and troubleshooting of motorized pulley will be introduced as shown as below:

1.The current of motor is low, and the cylindrical body doesn’t rotate.
Troubleshooting method: Motor should be checked regularly to know whether it is normal or not. If motor is normal, it indicates that there might be broken in coupling pin shaft ,after changing the coupling pin shaft and start the machine to prevent the more severe consequences.

2.Oil leakage in pulley ends and coupling rotating parts. 
Troubleshooting method: Tighten the spring coil or replace the grease seal.

3.Oil leakage in end cover. 
Troubleshooting method: Tighten the oil plug and change to grease resistant rubber gasket.

4.Oil leakage in the connection parts of cover and cylinder body. 
Troubleshooting method: Check whether the connecting bolts are loosen or not and check if the ventilation plug and air outlet are blocked, unclogging it or clean it if it is blocked.
