Electronic belt scale is a highly sensitive dynamic measuring instrument, and its quality and performance, correct and reasonable installation and commissioning, application environment, conveyor, and maintenance operations during use all affect the measurement accuracy and stability.
Therefore, in order to ensure the accuracy of electronic belt scales in application, multiple measures need to be taken, from product selection, installation and debugging, to operation and maintenance, all of which should be fully considered, and some necessary measures should be taken in place.
Firstly, when choosing an electronic belt scale, one should consider the specific application situation and choose the appropriate belt scale model based on actual needs, rather than blindly pursuing low prices. However, there are also some basic requirements that need to be met, and the belt scale should meet the following requirements:
(1) The scale frame structure has good rigidity, small displacement, and good symmetry;
(2) The scale body can eliminate the influence of horizontal and lateral forces on weighing, and reduce the impact of belt deviation on measurement;
(3) The supporting point of the belt scale should be a non friction supporting point that does not require maintenance or a non supporting point;
(4) The horizontal surface of the scale body that may accumulate dust is small, reducing the accumulation of dust on the scale body;
(5) Simple structure, easy to install and maintain;
(6) The tare weight borne by the weighing sensor should be as small as possible, while the material load it bears should be large;
(7) The weighing sensor should have high precision, high sensitivity, and the ability to resist lateral force, overload protection, temperature compensation, etc. It should also have strong anti-interference ability to ensure detection accuracy;
(8) The speed sensor should be sensitive, operate flexibly, not jump, and able to overcome the influence of belt tension on measurement;
(9) The instrument should have fast processing speed, simple and convenient operation, and easy calibration and verification.
Again, during the use of electronic belt scales, changes in belt tension have a significant impact on weighing. Measures should be taken to minimize belt tension as much as possible and reduce its impact on measurement
(1) The belt conveyor should be equipped with an automatic belt tensioning device to maintain a constant change in belt tension as much as possible;
(2) When installing the electronic belt scale, it is necessary to choose a position with low tension and minimal variation;
(3) When conveying materials, try to transport them as evenly as possible to reduce tension changes caused by material fluctuations;
(4) Add calibration compensation function.
Finally, necessary methods and measures should be taken to maintain the long-term stability of electronic belt scales:
(1) Raise the center support roller to avoid errors caused by the vibration of the active and passive rollers. When the main and passive rollers rotate and produce vibration, the belt will also experience bumps and vibrations, which will affect the electronic belt scale. If the upper surface of the center roller of the groove roller is higher than the roller by a certain distance, it can avoid the influence of roller vibration.
(2) Both belt scales and belt conveyors should not be used in wind and rain. Belt scales should be kept outdoors as much as possible. If they are to be used outdoors, protective devices can be added.
