Product description
The composition principle of quantitative loading system:
Quantitative loading control system is composed of batch controller, flow meter, thermometer, liquid level switch, grounding switch, control valve, explosion-proof LED large screen, upper computer, etc. to form an automated quantitative fuel delivery system.Quantitative loading control system is composed of batch controller, flow meter, thermometer, liquid level switch, grounding switch, control valve, explosion-proof LED large screen, upper computer, etc. to form an automated quantitative fuel delivery system.The on-site loading situation is summarized in the control room, and various loading reports are centrally monitored, managed, displayed and printed by the computer.
The AWZ series loading instrument adopts industrial grade products with mature technology and reliable performance. Its core controller adopts a programmable controller commonly used in the industry. The LCD display and keyboard input part adopts imported integrated LCD operation terminal, and the upper computer monitoring software adopts The mature industrial control configuration software makes this product have an absolute advantage unmatched by single-chip products in terms of advancement and reliability.
The hardware of the quantitative loading control instrument of this system is mainly composed of a micro PLC module, a liquid crystal operation panel (including operation keyboard) and other auxiliary equipment (terminals, power supply, explosion-proof box, etc.). Based on this hardware design and configuration, the whole device has many natural advantages with the traditional system consisting of single-chip integrated circuits. |  |
Main functions of quantitative loading system:
1. Automatic oil distribution and centralized management function; can realize the automation of the oil distribution process, guarantee the highest loading accuracy of ±0.2%, and improve production efficiency
2. Safety alarm protection function: it can realize various fault alarms, as well as electrostatic oil spill protection, emergency shutdown protection
3. Loading process monitoring function: online monitoring of the fuel delivery status of each loading arm position
4. Replacement of tickets and oil: customizable printing of loading tickets and storage of these tickets, with password identification function
5. Offline loading function: when the host computer cannot be operated, it can be easily switched to on-site loading
6. Management function: Accept the production data and production plan of the superior management network to arrange production, generate reports and purchase, sell and inventory systems
7. Communication networking function: provide standard DDE and OPC interfaces, which can facilitate communication with DCS, ERP and other control and management systems

Configuration requirements and characteristics of bottom loading system |
Batch controller: one machine per position |
Piston-type CNC electro-hydraulic valve: For non-corrosive, high-temperature, and high-pressure media, you can choose a control valve made of carbon steel, 16MPa pressure, and normal temperature. The piston type numerical control electro-hydraulic valve has excellent constant current and multi-stage control functions. The linear control is excellent, the constant velocity response is adjustable, and the low pressure drop and the small flow rate can be stably controlled at one liter per second when the flow rate is high, which can realize the constant flow function. It can solve the overshoot problem and eliminate the water hammer phenomenon. And long life. The high precision of oil delivery. |
Flowmeter: No special requirements can choose the volume flowmeter or mass flowmeter made of ordinary carbon steel. If there are higher requirements for the loading accuracy, it is recommended to choose an imported mass flow meter with 0.1% accuracy. |
Electrostatic protector: The electrostatic grounding protector is a grounding device to ensure the safety of the loading process. It has the interlocking function of refusing to load the vehicle without grounding signal and emergency stop when the grounding resistance is greater than 100Ω. At the same time, the device itself has a sound and light alarm function, and on-site operators can troubleshoot the fault through the color, sound and status of the light. |
Overfill protector: Anti-overflow protection is a safety device to prevent materials from overflowing the tanker when an accident occurs during loading. When the material comes into contact with the anti-overflow probe, the device will send an interlock signal to emergency stop. At the same time, the device has a sound and light alarm function, and the on-site operator can troubleshoot the fault through the color, sound and status of the light. |
loading arm: The bottom-loading arm of the bottom loading type is 2.5MPa, normal temperature type, which is volatile to the bottom loading medium. For environmental protection and resource waste, it is recommended to choose the gas and liquid type. AL2543 loading arm with two-phase function. |
