The electronic belt scale is very good to improve production efficiency, do you know?Let's take a look!
It is very good for the electronic belt scale to improve production efficiency
When it comes to the selection of electronic belt scales, the first thing to do is to understand the physical parameters and the surrounding environment. For example: dosing range, belt length, conveying speed, belt inclination, required accuracy, etc. We will help you choose a belt scale from the following aspects.
1. The direction of the application.
First, the materials involved in the production activities of the enterprise, such as coal, coke and other energy substances and important materials, or the purchase of electronic belt scales to be used in warehousing, docks and other trade settlement activities, should use higher precision belt scales, if the error caused by the first input accumulates, this is more than worth the loss. The transportation materials involved in the production activities of the enterprise should be used with a belt scale with high precision, if the error caused by the first input accumulates, it will outweigh the loss. The transportation materials involved in the production activities of the enterprise do not belong to Class A materials, so choose the electronic belt scale with high accuracy and general accuracy.
2. Load.
Then, according to the instantaneous flow rate of the material conveyed on the conveyor belt, the corresponding load cell is selected. After many years of analysis in the industry, the measurement accuracy of the electronic belt scale is most accurate when its load is at 40% to 60% of the maximum weight value when it is running.
3. Transportation environment.
Through several years of practice, we have found that if the belt conveyor in the workshop is long and the belt jitter is more serious, then it is recommended to choose an electronic belt scale with multiple roller scales, which can effectively improve the accuracy of daily measurementWhen the workshop belt is relatively short and runs relatively smoothly.
Technical measures to improve the measurement accuracy of the trailer type electronic belt scale, 4 tips!
1. Weighing body structure.
The structural design should be simple, easy to install, good anti-eccentric performance, accurate force transmission and reliable limit. The scale body fixing bracket should be directly installed on the bracket of the conveyor, and can be adjusted and fixed in the vertical direction to ensure the corresponding height of the weighing frame. The belt scale body should reduce moving parts and friction parts, reduce damage, reduce force transmission links, and naturally improve accuracy and durability. In addition, it is also necessary to prevent the problem of pulsating shock loads, which can affect the accuracy of measurement.
2. a load cell.
Load cells must have fatigue resistance, high impedance, high bridge voltage, high sensitivity and high resolution, otherwise it is difficult to maintain the stability of accuracy.
3. Speed sensor.
Because the weighing result is the product of weight and velocity, the accuracy of the velocity signal is just as important as the weight signal. The cantilever of the speed sensor should have a certain length, the friction wheel should have a relative weight, and the rotation should be flexible to ensure the accuracy of the speed signal.
4. Instrument. The instrument can be said to be the heart part of the electronic belt scale, requiring its accuracy and stability to be continuously improved, and the function to be continuously improved, such as alarm, automatic zero calibration, range calibration, temperature compensation, self-diagnosis, analog calibration, power-off protection and other functions.
