Equipment introduction and application of weighing and measuring tanks
Weighing and measuring tanks are widely used in the fields of fine chemistry, medicine, food, and new energy. It has very high accuracy and can match the formula of the production process to produce qualified products.
The composition of the weighing and measuring tank:
storage tank
Weighing module
Electric regulating valve
Pump
PLC control
How the weighing and measuring system works
1. The weighing module and the pump are linked to control the start and stop of the pump according to the weight. After the weight in the metering tank reaches the specified weight, the weighing module sends a signal to the pump to stop working. Pumps using variable frequency have higher metering accuracy.
2. After the PLC system gives the weight of the discharged material, the electric regulating valve opens and starts discharging. After the discharged weight reaches the specified weight, the electric regulating valve closes.
3. Under theoretical conditions at C3 level, the material accuracy can reach a control accuracy of 1/3000.
4. When selecting a weighing module, be sure to choose the appropriate accuracy based on the weight of the material. The greater the difference in total weight, the greater the error in material discharging.
5. When there is a large difference in the weight of the discharged materials from the same measuring tank, choose a weighing module with higher accuracy, such as C6 and C10. You can choose one according to the actual situation.
