Those problems and methods of use need to be paid attention to when installing a weightlessness scale

Weightlessness scales have an important position in the market. The editor will take you to understand those problems that need to be paid attention to during the installation process of weightlessness scales and lose knowledge of how to use weightlessness scales correctly. Precautions for installing a weightless scale 01. The weighing platform must be firm. The sensor is an elastic deformation element, and external vibration will interfere with it. The most taboo of a weightless scale during use is the impact of environmental vibration. 02. There can be no air flow in the environment because the sensor selected to improve the accuracy of weighing is very sensitive, and any wind and grass will interfere with the sensor. 03. The shorter the connection distance, the better the connection distance between the large silo and the upper hopper, the better, especially for those materials with strong adhesion. When the connection distance between the large silo and the upper hopper is longer. The more materials adhere to the pipe wall, when the material on the pipe wall adheres to a certain degree, once it falls, it will be a very big disturbance to the weightlessness scale. 04. Minimize the connection with the outside world as much as possible. Minimize the connection with the outside world. Any external weight acting on the scale body must be kept constant in order to reduce the influence of external forces on the scale body. 05. The feeding speed must be fast. The feeding speed must be fast, so we must ensure the smoothness of the feeding during the feeding process. For materials with poor fluidity, in order to prevent them from bridging, the best solution is to add mechanical agitation in the large silo. The biggest taboo is the air flow to break the arch, but the agitation cannot be kept running. The most ideal is to maintain the mixing and feeding process Consistent, that is, keep in sync with the replenishment valve. 06. The upper and lower limit values u200bu200bshould be set appropriately. The lower limit value of the replenishment and the upper limit value of the replenishment should be set appropriately, so that the bulk density of the material in the hopper between these two quantities is basically the same. This can be obtained by observing the frequency change of the frequency converter. When the bulk density of the materials in the hopper is basically the same, the frequency of the frequency converter basically does not change much. Setting the lower limit value of the feed and the upper limit value of the feed properly can improve the control accuracy during the refill process, because the weightlessness scale is under static control during the refill process. If the frequency of the inverter before and after the refill can be maintained basically No change, the measurement accuracy of the replenishment process is basically guaranteed. In addition, under the condition that the bulk density is basically the same, try to reduce the number of refills, that is, try to refill more materials each time. These two contradict each other and must be considered in an overall manner. This is also the key to ensuring the accuracy in the feeding process. 07. The replenishment delay time setting should be appropriate. The replenishment delay time setting should be appropriate. Make sure that all the materials have fallen on the scale body, and the shorter the setting time is, the better. During the debugging period, you can set the delay time longer, and observe how long the total weight on the scale body can stabilize (the total weight on the scale body) after each replenishment is completed. Less stable). Then this time is the appropriate feed delay time. Through the above seven steps, we have learned that in the process of installing the weightlessness scale, we need to pay attention to those problems. Next, how do we use the weightlessness scale with a deeper understanding? How is the weightlessness scale used? The first step: After the equipment is installed, put the customer's materials into the hopper of the weightlessness scale for material calibration. The calibration of the loss-in-weight feeder is of great significance to the stable operation of the subsequent loss-in-weight feeder. The second step: After the calibration is completed, the weightlessness scale can measure and feed normally, and actually run. During the operation of the weightlessness scale, the weighing sensor will collect the most accurate flow data in real time and send it to the weighing controller for processing. The third step: After calculation, the real-time processing data are respectively transmitted to the touch screen for screen display and data communication, and the panel controls the speed of the motor. In this way, the purpose of real-time adjustment of the flow can be achieved. At the same time, the weightlessness scale operates in a precise volume mode to ensure a stable and accurate flow.
