Function and Advantages of Nitric Acid Quantitative Dosing and Metering System for Automatic Caustic Soda Filling Equipment:
1. The equipment performs continuous temperature tracking and density compensation of the metering medium during the metering process, ensuring that the metering accuracy is not affected by changes in medium temperature.
2. Direct mass metering of the medium, with the metering unit: kilograms. It can be directly loaded into drums on the vehicle, eliminating the need for cumbersome processes such as tare weighing, weighing, loading, and unloading of packaging drums.
3. When filling a tank truck, the equipment only requires input of the desired number of kilograms to be filled—press start, and the pump will automatically stop and the corresponding pipeline will be sealed upon reaching the target quantity.
4. The desired filling quantity per drum can be arbitrarily set via the control instrument's 0–9 numeric keypad, with a quantitative range of 1–99,999,999 kilograms.
5. The equipment uses pump pressure to convey the medium, enabling rapid filling. Taking a DN40 caliber as an example: 200 kg/drum, 60 drums/hour; DN50: 100–120 drums/hour.
6. The pipeline materials available include cast iron, carbon steel, and stainless steel. The metering section can be fully explosion-proof.
7. The built-in miniature Epson wheel printer can automatically print after each batch of filling: single drum weight, number of filled drums, total weight, and filling date and time. (The explosion-proof control instrument does not include a printer.)
8. Daily cumulative and total cumulative values can be printed and viewed.
9. The combined filling head is equipped with a pressure-controlled check valve, which automatically opens when the pump starts and closes after the pump stops.
10. High-precision flow meters ensure a metering accuracy better than 0.2%.
11. Labor-saving, with only 2 personnel required to complete the filling process, thereby reducing labor costs for the enterprise.
Operation Process of the Nitric Acid Quantitative Dosing and Metering System for Automatic Caustic Soda Filling Equipment: Taking 200 kg/drum and 50 drums to be filled as an example:
1. Insert the filling head into the drum.
2. Keyboard operation: 200 → Set Quantity → 50 → Start (Filling begins, and the pump automatically stops upon reaching 200 kg).
