Working principle: The system consists of the main components such as the host (quantitative controller), flow meter, filter, pump, electro-hydraulic (magnetic) valve, and on-site explosion-proof large screen display (see system composition diagram). Its work mainly includes accurate quantitative distribution and filling of incoming and outgoing materials, as well as the entry and exit of various materials. Quantity management
Querying historical data of daily, monthly, and annual incoming and outgoing materials, querying, compiling, and printing reports for each batch and total quantity of materials issued and received.
If equipped with an invoicing system, after invoicing in the business room, the invoicing information can be directly entered into the control computer through the local area network, and can be distributed and filled at any time. All filling data can be entered into the factory level computer management network through the local area network to achieve dynamic management. An external liquid level display monitoring system can be used to detect the liquid level of storage tanks in the tank area and the oil storage capacity of each tank.
Functional features: 1. The system issues materials in kilograms, and weight calibration is based on weighing, with actual measurement errors
All within 0.2%. The temperature sensors for each storage location are installed at the inlet of the flow meter. Therefore, when switching between different oil tanks, the temperature compensation follows the changes in the switched oil products. The intelligent temperature detection error is ± 0.1 ℃, and the integrated IC module controls the material issuance. Also, liters of hair oil can be used.
2. The entire material dispensing process adopts intelligent fuzzy control, and the electro-hydraulic valve switch control adopts multi-stage control mode, which automatically adjusts the dispensing flow rate without user intervention, and there is no "water hammer" phenomenon in the entire dispensing process. DH6409VE can also control pneumatic ball valves, electric ball valves, solenoid valves, etc.
3. Real time static electricity and oil spill detection ensure material safety.
4. Static electricity, oil spill, pump, valve, temperature status are displayed on site, and the working status is clear and easy to understand at a glance.
5. Each storage location is independent of each other, so stopping, switching, or malfunctioning does not affect other storage locations and the entire system
The operation.
6. There are records in the database for power outages or interruptions in operation.
7. Operators manage operations based on permissions and have clear responsibilities.
8. The various data reports provided facilitate financial accounting and production management.
9. System functional modules can be modified or added according to user requirements (1-32 custom controllers can be connected).
