Matters should be noted during belt sway switch installation and adjustment

Belt sway switch is used to check the belt running deviation of the belt conveyor, it is a safe protection device of automatic alarm and stop when the belt running deviation appears.Belt sway switch is fixed on the conveyor belt bracket, action bar is at the side of the belt, when the belt running deviation appears, force the action bar deviation, and touch the alarm micro switch. If the belt running deviation continues,will touch another group of contact, and the conveyor will be protective to stop.

In the installation and adjustment of belt sway switch, what matters should we pay attention to? PK Machinery will answer for you!

1. Belt sway switch should be located on both sides of the conveyor belt, the vertical roll should be vertical with conveyor belt edge flat, and both sides of the conveyor belt are located at 1/3 height of vertical roll.

2.The distance between the vertical roll of belt sway switch and the normal position of conveyor belt should be 50 ~ 100 mm.

3.The quantity of belt sway switch ought to be determined according to the length of the conveyor, types and arrangement. Commonly it is located on the conveyor head, tail, convex segment, concave segment and the middle position.(Note: when the conveyor is longer, a pair of belt sway switch can be located every 30 ~ 35 m.)

4.Belt sway switch connects the conveyor middle frame through the mounting bracket, switch bracket will be welded with conveyor frame after the installing completion of the conveyor, and belt sway switch shall be bolted in the bracket.

Ways to Maximize the Performance of Belt Conveyor

Ways to Maximize the Performance of Belt Conveyor

During application of belt conveyor, it is beneficial to reduce operating resistance by using high precision conveyor rollers and high performance belt. Revolving resistance of rollers and forward resistance of belt conveyor account for 50% main resistance in belt conveyor. If the belt conveyor length is more than 80m, main resistance will be influenced by device condition, friction coefficient related to real working condition, conveyor length, rotating quality in unit length of roller, belt quality, material property, etc.

Apart from above mentioned influential factor, we can refer to the following ways to maximize the performance of belt conveyor:

1.Reduce or adjust belt deviation;

2.Add lubricating oil to components of belt conveyor;

3.Clean up the sundries produced in transportation promptly;

4.Tension force of belt conveyor should be adjusted the best status;

5.Please add oil to conveyor pulley at fixed period to ensure smooth rotation;

6.It’s better to adopt vulcanized joint, though it costs too much money, it can keep a longer service life(especially suitable for fixed belt conveyor).

How to prolong lifespan of belt conveyor

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.
