Detailed explanation of the practical application of the principle of weightlessness scale

The weightlessness scale is a weighing system that is continuously displayed from the last rest. The operation process in the weightless state is carried out in the raw material warehouse, which can carry out high linearity and make the structure easy to seal. Therefore, it has a very large improvement compared with the spiral scale in the operation of granular raw materials. It can be used as a condiment for fine raw materials such as concrete, quicklime powder, and pulverized coal. At this stage, the key to accurate measurement of rotating mixing machinery in China is the volumetric method, electronic belt scale and spiral scale. The measurement accuracy of electronic belt scales used in the ground field of our country is generally only about 5%, which is different from the precise measurement, and the long-term authenticity is poor. The differential signal signal reduces the basic premise of the average error of the medicine (weightlessness state). Taking weighing silo and feeding organization as all scales, according to the symmetry weight data signal template of the electronic weighing instrument and the upper computer software, the conversion rate of the net weight per unit time is accurately measured as the total flow of instantaneous speed. According to the technical solutions of various hardware and software, it is very important to obtain the specific total flow that can be used as the target of the operation process. It is the basis for the proper and accurate measurement of the weightlessness scale. Figure 1 shows a typical approach. Based on PID feedback and ant colony algorithm, FC carries out operation and calculation close to the overall target total flow, and outputs adjustment data signals to operate soft starters and other feeder control boards. Differential signal signal reduces the average error combined with actual application. From the basic elements, it can be seen that the scale body and mechanical equipment of the supplier organization have not been damaged, only the reason (difference) of the net weight error has been accurately measured. Compared with the traditional dynamic and accurate measurement and verification method, the advantages are obvious. The goal of the operation process is the total flow (th, kgmin). When the raw materials have excellent transportability and the precision of accurate measurement and inspection is high, the weightlessness method can be selected for accurate measurement and inspection. The manufacturing process of weightlessness scale. Refer to Figure 2. The design of weightless scale must pay attention to the factor of precision. The net weightlessness scale takes into account the characteristics of data type scales and dynamic scales. Therefore, when designing the system software, it is stipulated that the scope of transportation rate is moderate. Generally, the actual effect of transportation with rated voltage of 60% to 70% is the best in specific work. When selecting communication and variable speed, the frequency of resolution should be 35~40Hz. Which guarantee has a very large adjustment range, because when the delivery rate is too low, the authenticity of the system software is very poor. Whether the sensor test category is suitable or not depends on the calculation method. In other words, the sensor has also selected 60%~70% of its inspection range, and the data signal has a wide range of transformation, which is very beneficial to improve the precision. The design scheme of the mechanical system must ensure the excellent circulation of raw materials. In addition, the canning time is short, and canning raw materials is not suitable for too much. Generally, it takes 5-10 minutes to spread the raw materials once. The transmission device of auxiliary machinery and equipment should operate stably and have good linearity. Application prospects. Along with the rapid development trend of automatic automatic control systems for electronic equipment, the precision measurement and inspection precision of weightlessness scales has increased from 0.3% to 0.5% to 0.1% to 0.2%, which even exceeds that of data type scales. The key to this new technology is the use of data information weight sensors.
