How to prolong lifespan of belt conveyor

Quality of belt is the main reason to impact on belt conveyor lifespan, so it must purchase the belt with high quality. Meanwhile, it should make sure that sweeper is reliable to use so that there is no material on the return belt. Otherwise, materials adhered to return belt will be taken to the surface of drive pulley and bend pulley, then it will damage belt and reduce its lifespan.
There are some problems in the use of belt conveyors sometimes, to which require you to pay attention that you can greatly extend the service life of belt conveyor.
1. If there is the phenomenon of belt slipping on drive pulley, users should find the reasons and adjust it promptly.
2. Please always check the belt connectors, if there is local damage, please repair it or replace conveyors joints.
3. Please check rollers using conditions regularly. Adding proper lubricating grease into sealing ring when making maintenance. And replace inflexible rotating rollers immediately.
4. It must add good quality lubrication into all rotating parts of belt conveyor. Please add lubrication at fixed period in accordance with the requirements.
5. Please ensure that the cleaning device has good working conditions, and the damaged components should be replaced.
6. Please check tension level of belt conveyor regularly. If the belt is loose, please tension it promptly and observe whether the belt is off tracking, otherwise it should be adjusted timely.

The application of conveyor belt fluid coupling

Fluid coupling is a used fluid transmission component. Motor drives coupling pump wheel rotation, pump impeller blade agitates intracavitary working liquid, under the centrifugal effect,pump wheel turns mechanical energy into liquid energy, then passes to the turbine blades, turbine passes the absorbent liquid energy to the machine.
Fluid coupling has the function of flexible transmission,slow down the impact and the isolation of torsional vibration, prolong the start-up time, reduce the starting current,make the motor light load start-up, solve the problem of heavy large inertia load start-up difficulties and protect the motor when overloads, energy and power saving effects are remarkable.
On the conveyor, fluid coupling has the function of connecting motor and reducer ,it replaces the mechanical coupling. The belt conveyor fluid coupling has two effects:
1.Overload protection
If the belt conveyor is overload, fluid coupling slip frequency increases, working fluid warms up, fluid coupling will spray without burning motor to a certain temperature. Of course sometimes coupling will be installed with a temperature control device, when work liquid superheats, temperature control device can control the motor and cut the power cut to protect the motor.
2. Flexible-start
When motor starts,belt conveyor starts slowly and acceleratedly , this can reduce the grid big impact to make the motor start up in light load. At the same time,it can reduce the effect of belt tension,protect belt and prolong life, especially under the heavy load start-up.

Do you know difference of TD75, DTII and DTIIA series belt conveyor?

Specifications of TD75, DTIIA, DTII series belt conveyors are the national standard of China belt machine, which represent three types of conveyors.During the model selection,the standard should be noticed. How to choose a proper type to save client’s cost? The following is the characteristics of the three types of conveyors:
TD75 series conveyor is the first standard belt conveyor, it can be used to convey small lump, granular, powder material, due to simple structure, low cost, easy maintenance, convenient maintenance, and large transport capacity,TD75 series belt conveyor becomes a common machine,it can be single or multi sets running to form a horizontal or inclined conveyor system.
DTII series belt conveyor is designed according to the components. The designers can design and assemble the conveyor according to the requirements of transportation, different terrain and working conditions,it has a wider use compared with TD75 type.
DTIIA series belt conveyor a heavy duty machine is mainly used to transport large density, large transport capacity and long transmission distance, conveyor selection is determined according to many parameters.

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.   

The factors of affecting dysfunctional roller

Manufacturing quality conveyor idlers. Conveyor idlers problem mainly in the manufacture of bearing stiffness is not enough, it is difficult to ensure the idler assembly precision, thereby constraining the flexibility roller operation.

Seal lubrication and maintenance. Since the conveyor working environment is more severe, in general, the use of on-site dust are big, big bearing seal in the form of impact on the operation of the roller flexibility, if the seal is not good, it is easy to enter the dirt cause the bearing roller rotation is not flexible: in addition, the bearing grease if the general calcium-based grease dries easily change color, can not play a good lubrication.
Marry Christmas！

how to solve Conveyor idlers dysfunctional ?

Roller operation flexible approach:
On roller manufacturing process to ensure the accuracy requirements, such as precision stamping bearing bore to reach three, dimensional tolerances of the pipe ends, concentricity and ovality must meet the national standard, not tolerance.
Sealed lubrication, in addition to manufacturing quality assurance, but to go with a good lubricating materials, such as lithium grease, can be improved bearing lubrication, which prolong the service life of the roller is necessary.
Bearing radial ball bearings using plastic sealing ring labyrinth seal structure, so that can guarantee work roller reasonable force, while good dust effects, resistance, and easy assembly and disassembly, easy to maintain, can effectively reduce the transport machine operating costs.

Application of Sidewall Belt Conveyor in Thermal Power Plant

1.Requirements
Sidewall belt conveyor is the major equipment to convey coal and lime-ash in thermal power plant. Therefore it has high requirements for the security of equipment. Generally speaking, the whole transit line is equipped with twin channel sidewall belt conveyor, one is put into use, another is as standby application device. Thus, this coal handling system must be equipped with sidewall belt conveyor with 2500m-3000m length. Applying sidewall belt conveyor to thermal powder plant, it can not only simplify procedure, but also save cost.
2.Features
Due to power plant has high requirements for the security of equipment, technical requirements of sidewall belt conveyor are as follows:
1) It has different requirements for belt conveyor when it used to receive, convey or discharge materials. For instance, if the belt conveyor is used to receive materials, the belt speed of it shouldn’t be too high. If it is used to convey materials, it requires that trough angle of idler decrease properly. If plow discharger is put into use, the cover rubber of belt surface should be thicken properly. 
2)The belt speed should be low. Belt conveyor is mostly arranged in workshop, so it has high requirements for coal dust control. According to domestic and foreign practical experience, it’s better to adopt lower speed.
3)After installation of this machine, it seldom changes its layout.
4)Different coal type has different requirements for belt conveyor. For example, large coal particle size needs impact idler with high quality. Coal with less water and more dust needs guide chute with good sealing.
