Why does the weightlessness scale fluctuate? How to maintain weightlessness scale
Weightlessness scale is a set of flow control system composed of field equipment and controller. Loss-in-weight scales will encounter fluctuations during work and operation. Today, the editor will introduce to you the reasons for the fluctuations in weight-loss scales and the knowledge of daily maintenance of loss-in-weight feeders. First of all, the reasons for the fluctuation of the weightless scale are as follows: Mechanical and electrical 1. Whether the inverter is working normally: Confirm the inverter control parameters, event records, and alarm information, and check whether the inverter input and output are tracked in real time. 2. Whether the feeding motor and screw work smoothly: Check the vibration and noise level. 3. Whether the fixed platform for spiral maintenance and the spiral shell is completely separated, and whether the weighing system and surrounding objects are in contact with or adhered to each other. 4. Whether the feeding spiral impeller is defective, if there is any defect, it will affect the uniformity of the feeding. We found that its spiral blades sometimes wear quickly, and occasionally there will be missing pieces, which affects the stability of the spiral feeding. 5. The soft connection between the weightless bin and the dry ore bin, and the soft between the weightless bin and the breathing tube. Whether the heat preservation of the soft connection between the spiral and the collecting hopper is normal. 6. When this happens, we must stop for maintenance. After understanding the reasons for the fluctuation of the weightlessness scale, we also understand the knowledge of the double-screw micro-weightlessness scale for the daily maintenance of the loss-in-weight feeder: usually when the equipment is used to supply materials, it is necessary to pay attention to the cleanliness of the equipment. When there are stains or large amounts of dust, you should clean them in time to keep the equipment in a clean and dry state. In addition, the equipment needs to be regularly calibrated during the use of the equipment. Some equipment may have deviations in accuracy due to long-term use, and even the calibration can avoid errors and ensure the accuracy of the weightless feeding equipment. The current weightless feeder has a reasonable structure design, and the staff usually need to lubricate and maintain the equipment regularly. If the lubrication effect of the equipment is not good, some parts are prone to looseness. After the lubrication treatment, the operation effect of the equipment will be better. Stability can also achieve higher production efficiency. Usually when using a weightless feeder, the staff should also pay attention to whether the dry and wet state of the material meets the standard. When the humidity of the material is too high, the weight of the material will increase, which not only affects the accuracy, but also causes a certain amount of equipment. Therefore, the maintenance knowledge needs to be mastered in the process of using the weightless feeding equipment. This article introduces the reasons for the fluctuation of the weightlessness scale and the sharing of knowledge about the maintenance of the twin-screw micro-weightlessness scale. You will also have more understanding of the weightlessness scale in the future.
