Explosion proof liquid quantitative control system

Explosion proof liquid quantitative control systemcanUsed in conjunction with various equipment such as reaction tanks, reaction vessels, and reaction kettles to perform quantitative water addition, quantitative batching, automatic quantitative water addition, and automatic quantitative feeding operations, replacing manual operations; At the same time, the equipment has the characteristics of simple composition, easy installation, simple use, safety and reliability, economic practicality, and high precision. It is suitable for various industries and equipment for quantitative water addition, quantitative feeding and other devices. As workers' wages continue to rise, automatic control has become a trend. Currently, many enterprises use or need to improve one of the projects,It is easy to operateEasy to learn，It directly replaces manual feeding and manual batching, and at the same time, this systemDisplay intuitively，Manual control or automatic controlCharacteristics such as combination.Can be installed in hazardous areas containing flammable gases and explosions.

Explosion proof liquid quantitative control systemSimple composition, easy installation, easy to learn and operate, reliable accuracy. During installation, it basically does not affect the actual pipeline layout on site. As long as the pipeline layout is done according to the actual requirements, flow meters and control valves can be installed on the pipeline layout, and the wires can be connected according to the internal wiring markings of the control box to complete the installation.

1main components

As shown in the figure, we provide a flow meter, control valve, and WK quantitative control box. The pipeline is arranged on site according to the actual situation. The control valve is located near the outlet, and a flow meter is installed 1-2 meters in front of the control valve. A certain straight pipeline can be ensured in front of the flow meter; When there are impurities in the medium, a filter should be installed in front of the flowmeter; When there is pressure in the pipeline, the installation of the pump does not need to be considered; The WK quantitative control box is installed in a location that is convenient for manual operation.

IIControl principle description

According to the actual requirements, the quantitative value that needs to be fed is set in the WK quantitative control box and the operation is started. Then, the pump or control valve on the pipeline is opened, and the fluid flows. The flow meter starts to measure and transmit the flow signal to the WK quantitative control box. After the cumulative value in the WK quantitative control box reaches the set quantitative value that needs to be fed, the output signal is sent to close the pump or control valve on the pipeline, completing a quantitative feeding operation.

IIIAdditional Function Description

1Full Chinese large screen LCD display with external buttons for operation;

2. Quantitative shortage canning function: intermittent quantitative continuous dispensing operation;

3. When using the same amount of material, the one click start function is activated;

4. There are 8 sets of commonly used feeding quantities, and the startup function is selected;

5. The function of setting the amount of material (digit: 999.999) and the volume or mass of material (kilograms, tons, liters, cubic meters) at any time;

6. Choose and set the material unit, quality, and volume arbitrarily, and set the density value parameter internally;

7. Real time temperature and pressure compensation density can be performed; Fixed temperature values can also be set in the table;

8. The function of recording material feeding data includes: starting material feeding time, ending material feeding time, sizing material, etc;

9. Simultaneously control the pump and the large and small valves to achieve precise control, and equipped with a pump control interface, with the function of delayed start or early shutdown of the pump;

10Power off maintenance function: In the event of a power outage during the feeding process, the quantitative controller automatically maintains the working data and status before the power outageEnsure the integrity and continuity of material feeding.

11. Optional features: USB data transfer function, micro printer printing function, 485 or 232 communication, remote control operation, etc;

12. Multiple branches can be converted for material issuance or multiple entrances can be converted for material issuance according to requirements;

13. We can customize an integrated box with a pump and a movable feeding operation according to requirements;

14. Various customized equipment can be customized according to requirements.

4、 Technical parameter description

5、 Parameter description to be provided when placing an order (the following parameters are extremely important and directly affect the selection and actual feeding effect)

1. Details of the feeding medium: specific name (or chemical name and composition) of the feeding medium, medium temperature, medium pressure, flow rate (approximate flow range is sufficient for us to select);

2. Explain the requirements for control, such as the size or range of each quantitative value (especially the minimum amount of material to be injected must be informed), the required flow rate (such as the amount of material to be injected and the time required to complete it), the frequency of material injection control, the diameter and material of the existing pipeline, and other requirements;

3. Determine the control cutoff equipment: If there is pressure in the pipeline, only control valves (such as solenoid valves, pneumatic valves, etc.) need to be installed; If there is no need to install a feeding pump, a control valve should be provided at the same time. The WK quantitative control box can control both the pump and valve simultaneously, achieving automatic control.
