The accuracy and stability of electronic belt weigher, which is used as a dynamic measuring equipment for bulk materials, is related to the direct interests of enterprises. For example, in the settlement of port cargo trade, inaccurate weighing will directly cause economic losses to enterprises or consumers. In order to maintain the stable operation of the electronic belt scale, it is necessary to carry out correct daily maintenance for the electronic belt scale.
1. Adjust the belt in time
Those who are familiar with the belt scale know that the belt of the belt conveyor is very easy to deviate, resulting in a serious impact on the measurement accuracy of the belt scale. Therefore, when the belt is running with no load, it must be ensured that the belt is in the center of the conveyor idler, and it must be adjusted in time in case of deviation.
2. Maintain stable belt tension
In addition to belt deviation, belt tension is also an important factor affecting the accuracy of the belt scale. Therefore, it is important to adjust the belt tension in time to keep it constant. It is worth mentioning that if the belt tension is adjusted, the belt scale will be calibrated again to ensure that the measuring accuracy of the belt scale will not be affected.
3. Timely clean the residual materials of the belt
The rack of the belt conveyor often accumulates spilled materials, or it is easy to stick to the belt when conveying sticky materials. In these cases, attention should be paid to timely cleaning to prevent the materials from adding extra weight on the belt and affecting the measurement accuracy of the belt scale.
4. Periodic verification
Regular calibration of belt weighers is an essential part of maintenance, which is a disadvantage of all conventional belt weighers.
5. Instrument inspection
Check whether the keyboard keys of the instrument are flexible and whether the display is normal;
6. Weighing area protection
Prevent sensor overload caused by human factors. Do not stand or walk on the weighing area. The sensor is a precision measuring sensor with a certain range. Overload will cause sensor damage.
The above work is essential for conventional electronic belt weighers. However, with the development of technology, if you want to reduce some routine maintenance, you can choose the maintenance free intelligent belt weigher of Haiding Automation Technology. The scale frame has simple structure, less ash deposition, no need to clean frequently, and has its own calibration, saving many troubles.
