Weightlessness scale-working principle and manufacturer of weightlessness weighing scale
The vector weight scale is a common instrument in the industrial field. It is widely used. It is a static weighing device. It adopts the static weightlessness scale weighing technology and the silo weighing technology with load cell. The weightless weighing scale is also the same This kind of weighing equipment with intermittent feeding and continuous discharging, the loss control is carried out in the hopper, which can achieve higher control accuracy, and at the same time, its structure is easy to seal. What is the difference between a weightlessness scale and a weightlessness measurement scale, and what working principle they use to complete mechanical operations? , Below, I will give you a brief introduction to the knowledge of the two. First of all, the weightlessness scale is a type of weighing equipment with intermittent feeding and continuous discharging. Because the entire weightlessness control is basically completed in the hopper, it can effectively guarantee the accuracy of the control, and the structure is also It is easier to seal, so it has a greater rise when the powder is controlled, 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 weightlessness scale mainly consists of electrical control in the structural composition, and a 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 a start signal is detected, the system will then enter the working state, and automatically track the set value, and after appropriate adjustments to the steady-flow feeder, the frequency of the motor is used to control the material Adjust the flow rate. 2. The main work of the weightlessness scale on the control system: The control system will continuously collect the load sensor signal, and use the calculation relationship to calculate the material on the instantaneous flow rate. It can also calculate the instantaneous flow rate and design The flow rate is set to compare, and if there is a deviation, the deviation control value will be output. And through its frequency converter to adjust the speed of the motor, adjust the steady flow feeder in time to ensure that the instantaneous flow rate and the set flow rate remain the same dynamically, and finally reach the control that the weightlessness scale should need. Requirement, this requires more attention from the operator. The working principle of the weightless weighing scale is very simple, which is to control the discharge screw or electric vibrator 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 the weighing position, the discharge screw will fix the discharge amount according to the current speed, and at the same time control the material in the silo to quickly drop into the weighing hopper, when the material is loaded to the upper limit of the weighing Stop loading and fast loading can shorten the feeding time and improve the accuracy and control precision of weighing. Since the weightlessness scale adopts the combination of dynamic weighing and static weighing, and the combination of intermittent feeding and continuous discharge, the structure is easy to seal, and the system of the weightlessness scale can be set in two different positions on the flow of materials. The main purpose is to facilitate the operation, and it also has a variety of protection mechanisms, which play an effective role in system control. After understanding its working principle, the equipment can be operated correctly.
