The application of conveyor belt fluid coupling

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.

How to Select Conveyor Cover

How to Select Conveyor Cover

Application and Working Principle：

YD Conveyor Covers is well known as conveyor belt hood and used to protect transported material and conveyor belting, idlers and structure. Effectively they improve personnel safety; reduce loss of material to wind and stop grime and rain from damaging the idlers and belt.

YD Conveyor Covers is mostly used in power plant, cement factory, iron and steel factory, chemical factory, coal, port, jetty, mining and other enterprise. Our company provides fixed-closed type and open type. The color of the rain covers are mainly in blue, grey and white, and red (depend on client’s need).

Selection guidelines

1). Please tell us your belt conveyor’s width____mm and length____mm;

2). If possible, please indicate the opening width____mm of the conveyor cover; 

3). Please indicate the thickness of the cover you required____mm;

4). Every piece conveyor cover’s length is 970mm, except overlap installation, the effective length is 900mm. 

5). The material is colorized galvanized steel plate, the thickness are 0.5mm, 0.6mm, 0.8mm, 1.0mm.

6). Coud you tell us will you need fixed type conveyor cover or open-close type conveyor cover?

Part open-close type（generally for large belt conveyor width）

Whole open-close type

Characters of Belt Conveyor Buffer Bed

Characters of Belt Conveyor Buffer Bed

Belt conveyor buffer bed is mainly used in the blanking mouth below the belt guide chute. When the material is discharged, impact force caused by the falling materials can be reduced through elasticity of buffer bed to ensure that belt conveyor can operate normally. Here PK Machinery will introduce the main characteristics of belt conveyor buffer bed to you. 

I. Main features 

1. Smooth UHMW polyethylene surface can make the friction between belt and buffer strips minimize. 

2. The front and rear ends of polyethylene surface becomes into a curved, thus ensuring conveyor belt goes through smoothly. 

3. Each section of the buffer strip is connected by heat vulcanization. 

 

II. Characteristics 

1. No moving spare parts, reducing the daily maintenance cost. 

2. It has large supporting area to make average force, reducing belt slack or damage. 

3. It is suitable for various belt and angle and can withstand strong impact. 

4. It can be installed quickly, easy to check and replace. 5. Usually installed on the conveyor belt blanking point, can extend belt lifespan.

Several Ways to Solve Vibration Motor Frequent Trips

Several Ways to Solve Vibration Motor Frequent Trips

Most users know basic operation of the vibration motor. But during operation, there are many notices that we need pay attention, especially the frequent trips of vibration motor. Here PK Machinery will analyze the reasons of frequent trips and how to solve them for your reference: 

1. With regards to vibration motor air switch, if over-current protective device is unconformity, please replace it timely.

2. If motor cable is worn, this is mostly caused by wear and tear over time. Users can wrap it around by adhesive tape. 

3. Bearing is damaged or lack of oil so it will trip due to overload. Then users need to replace bearings timely. 

4. There is something wrong with vibration motor power or breaker aging. 

5. The magnetic circuit performance of the vibration motor declines, resulting in excessive current. 

Above mentioned points are the common reasons, and it is easy to deal with. As long as users find corresponding reasons, then adopt the corresponding methods, the problems can be resolved. If the vibration motor frequent trips are not caused by the above circumstances, please contact us promptly, our technical engineers will offer the help.

Ways to Judge Whether Roller Bearing is Failure

Ways to Judge Whether Roller Bearing is Failure

As we all know, roller is the main spare parts of belt conveyor, while bearing is precision parts of roller. But in the process of using, bearing is very easy to be damaged. How to avoid its failure? If users can identify whether the bearing is failure or not by not removing inspection, it will improve productivity greatly. 

Firstly, we can judge whether the bearing is faulty or not by sound bearing which requires the operators have a lot of experience. It must go through rigorous training to judge if the sound is produced by bearing. 

Secondly, we can judge it by the temperature of working device, but this method has some limitations. We need to constantly record the temperature changes to judge whether the bearing is failure in the operating conditions. 

Finally, we can judge whether the bearing is fault by dirty situation of lubricant when adding lubricant to bearing. If there are other different things mixed with lubricant, then the bearing must be damaged.

 

What Factors Lead to Inflexible Rotation of Conveyor Roller

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.
