The multihead weigher has an important position in the market. The editor will take you to understand the problems that need to be paid attention to in the installation process of the multihead weigher and the knowledge of how to use the multihead weigher correctly. Precautions for installing the multihead weigher 01. The weighing platform should be firm. The sensor is an elastic deformation element, and the external vibration will interfere with it. The most taboo thing about the multihead weigher is the impact of environmental vibration during the use of the multihead weigher. 02. There should be no airflow in the environment. Because the sensor selected to improve the weighing accuracy is very sensitive, once there is any disturbance, it will interfere with the sensor.
03. The shorter the connection distance, the better. The shorter 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 material adheres to the pipe wall, when the material on the pipe wall adheres to a certain extent, it will be a very big disturbance to the multihead weigher once it falls.
04. Minimize the connection with the outside world. Minimize the connection with the outside world. The weight of the outside world acting on the scale body must be kept constant. The purpose is to reduce the impact of external forces on the scale body. 05. The feeding speed is fast. The feeding speed is fast, so it is necessary to ensure the smoothness of feeding during the feeding process. For materials with poor fluidity, in order to prevent them from bridging, the best solution is to add mechanical stirring in the large silo. The biggest taboo is the airflow breaking the arch, but the stirring cannot run all the time. The ideal is to maintain the stirring and feeding process. Consistent, i.e. in sync with the refill valve.
06. The upper and lower limit values should be set appropriately. The lower limit value of the feed and the upper limit of the feed should be set appropriately, so that the bulk density of the material in the hopper is basically the same between these two amounts. 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 changes little. Appropriate setting of the lower limit value and upper limit value of the feeding can improve the control accuracy during the feeding process, because it has been said that the multihead weigher is in static control during the feeding process. If the frequency of the inverter before and after feeding can be kept basically The measurement accuracy of the feeding process is basically guaranteed.
In addition, in the case of ensuring that the bulk density is basically the same, try to reduce the number of feeding times, that is, try to replenish some more materials each time. The two contradict each other and should be considered in a coordinated manner. This is also the key to ensuring the accuracy of the feeding process.
07. The setting of the feeding delay time should be appropriate. The setting of the feeding delay time should be appropriate. Make sure that all materials have fallen on the scale body, and the shorter the setting time, the better. During the debugging period, you can set the delay time to be longer, and observe how long it takes for the total weight on the scale body to stabilize without fluctuating (not getting larger) after each feeding stable less). Then this time is the appropriate feed delay time.
Through the above seven steps, we have learned that in the process of re-installing the multihead weigher, we need to pay attention to those issues. Next, let's have a deeper understanding of how the multihead weigher is used? How is the multihead weigher used? Step 1: After the equipment is installed, put the customer's material into the hopper of the multihead weigher to calibrate the material. The calibration of the loss-in-weight feeder is of great significance for the stable operation of the subsequent loss-in-weight feeder. Step 2: After the calibration is completed, the multihead weigher can measure and feed normally and actually run.
During the operation of the multihead weigher, 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 the calculation, the real-time processing data are respectively transmitted to the touch screen for display and data communication of the screen, and the speed of the motor is controlled by the panel. In this way, the purpose of adjusting the flow in real time can be achieved. At the same time, the multihead weigher operates in an accurate volume mode to ensure stable and accurate flow.
