Vector weighing is a common instrument in the industrial field. It is widely used. It is a static weighing device. It adopts static multihead weigher weighing technology and silo weighing technology with load cells. It is a kind of weighing equipment with intermittent feeding and continuous discharging. The loss control is carried out in the hopper, which can achieve high control accuracy. At the same time, its structure is easy to seal. What is the difference between a weightless scale and a weightless measuring scale, and how do they complete mechanical operations? , Below, I will give you a brief introduction to the knowledge of the two. First of all, the multihead weigher is a weighing equipment with intermittent feeding and continuous discharging. Because the entire weightlessness control is basically completed in the hopper, it can effectively ensure the accuracy of the control, and it is also structurally It is easier to seal, so when the powder is controlled, it has a greater rise, and it is more suitable for use in fine materials such as lime powder, cement and coal powder.
Its working principle has two points: first, the multihead weigher is mainly composed of electrical control and the combination of the two parts of the scale body. In the electrical control system, it mainly refers to the control system. After the control system is connected to the power supply, the hardware will be self-checked first, if the state is normal. When it is detected that there is a start signal, the system will enter the working state, and automatically track the set value, and make appropriate adjustments to the constant flow feeder, and then use the frequency of the motor to adjust the material flow rate. Adjust the flow.
2. The main work of the multihead weigher in the control system: the control system will continuously collect the sensor signal of the load, and use the relationship of the operation to calculate the material on the instantaneous flow rate, and it can also calculate the instantaneous flow rate, and the setting If there is a deviation, the control amount of the deviation will be output. And adjust the speed of the motor through its frequency converter, adjust the feeder with constant flow in time, ensure the instantaneous flow, and the set flow remains the same dynamically, and finally reach the control that the multihead weigher should need. requirements, which requires the operator to pay more attention. The working principle of the weight loss weighing scale is very simple, which is to control the discharge screw or electric vibration machine according to the reduction rate of the material weight in the weighing hopper to achieve the purpose of quantitative feeding.
When the material in the weighing hopper reaches the lower limit of weighing, the discharge screw machine will fix the discharge amount according to the speed at that time, and at the same time control the material in the silo to quickly drop into the weighing hopper. When the material reaches the upper limit of weighing Stop charging, fast charging can shorten the feeding time and improve the weighing accuracy and control precision. Because the multihead weigher adopts the combination of dynamic weighing and static weighing, the combination of intermittent feeding and continuous discharge, and the structure is easy to seal, the system of the multihead weigher can set the flow of the material differently in two different positions, The main purpose is to facilitate operation, and it also has a variety of protection mechanisms, which play an effective role in system control. Only after understanding its working principle can the equipment be operated correctly.
