IIThe composition of the dual two-way material distribution and quantitative control system:

1. WDK type control box: It contains PLC, touch screen or quantitative control instrument, frequency converter, internal control circuit and other components (such as air switch, relay, contactor, etc.), external control buttons and indicator lights, etc. The standard size of single channel box is 400 * 300 * 200mm, and the standard size of PLC multi-channel box is 800 * 600 * 200mm. The input power supply (AV220V) is uniformly used to power the control box. Other equipment such as flow meters and measuring instruments for temperature, pressure, material level, liquid level, pH value, etc., as well as solenoid valves, are directly powered by the control box; And printing function can be added.

2. Flow meter: This is the foundation of control and directly affects the effectiveness of control. Therefore, the basic requirement is that the higher the measurement accuracy, the better, and it has signal output function. At the same time, there are many types of flow meters, and it is necessary to select the appropriate flow meter based on parameters and requirements such as measuring medium, pipeline diameter, flow range, explosion-proof, anti-corrosion, and protection level.

3. Flow interruption equipment: can be existing power equipment in the pipeline, such as pumps; It can also be a solenoid valve, electric valve, etc. installed later.

4. The power part of the control pump, solid or gas, rarely prevents the medium from flowing in the pipeline. The working power supply can be DC12V, DC24V, 20AC, 380V.

5. We can customize functions such as air washing and blowing after the residual medium in the pipeline is sent out, mixing while sending out materials, and stirring after sending out materials (customized according to customer requirements)

IIIThe Double Two Channel Material Distribution Quantitative Control SystemProcess control:

PLC、 After receiving the flow signal from the flowmeter, the touch screen or quantitative controller accumulates the flow rate internally and sets the required quantitative control value in the PLC programming software or controller. When the cumulative value displayed by the quantitative controller reaches the set quantitative control value, the PLC touch screen or quantitative controller outputs a switch signal. At this point, the switch signal is used to control the flow interruption equipment installed on the pipeline by connecting a relay or contactor, thereby achieving quantitative control.

1） Process control flow:

1. Set the total amount of tank A, water percentage, and concentration percentage, and automatically calculate the amount of water and concentration to be dispensed

2. Set the total amount of tank B, water percentage, and concentration percentage, and automatically calculate the amount of water and concentration to be dispensed

3. Set the material issuance time (1-9999 seconds) to 600 seconds, and apply it simultaneously to AB (ensuring that different proportions of raw materials are issued in about the same time). Automatically calculate the instantaneous flow rate data and transmit it to PID regulation

4. Feed the amount of water and concentrated material into the quantitative control data, and automatically stop the pump and close the solenoid valve when the amount is reached

5. When the emergency stop ammonium button is turned on, press the start button on the screen to run the equipment

6. When either water or concentrate falls below the lower limit of the liquid level, it cannot operate and an alarm signal is output (advanced relay alarm and signal output to PLC)

7. When tank A is below the lower limit, start the pump and open the solenoid valve. When tank B is below the lower limit, start the pump and open the solenoid valve (cannot work simultaneously and replenish separately)

8. When the lower limit alarm of tank A is triggered, the total ratio data of material A is used, and when the lower limit alarm of tank B is triggered, the total ratio data of material B is used

9. When there is a sudden power outage or pressing the stop button, data is saved. After power is turned on, it is in a paused state. Pressing the start button can continue (stopping the pump and closing the valve in case of power outage)

10. Stop the pump and close the valve (pause state) when the feeding is interrupted halfway (water or concentrated liquid lower limit alarm), keep the material issuance record, and then use * * minutes as the detection cycle (time can be set). If the water and concentrated liquid levels exceed the lower limit, the equipment will automatically start (open the pump and valve) to continue running

2） Display screen display section:

Total pre release quantity of tank A, percentage of water, percentage of concentrate, pre release quantity of water, pre release quantity of concentrate, current total quantity

Total pre release quantity of B tank, percentage of water, percentage of concentrate, pre release quantity of water, pre release quantity of concentrate, current total quantity, current total quantity

3） Traffic analysis:

10-20:1 Issue 300L of material

Material A: 272.73L-285.72L

B material: 27.27L-14.28L

Instantaneous flow rate after 10 minutes of material dispensing:

Material A: 1636.38-1714.32L/h

B material: 163.62-85.68L/h

4-8: Issue 300L of material

Material A: 240-266.67L

B material: 60-33.33L

Instantaneous flow rate after 10 minutes of material dispensing:

Material A: 1440-1600.02L/h

B material: 360-199.98L/h

Determine the flow range for measuring water:1440-1714.32L/h is recommended to use DN25 (48-58L/min)

Flow range of concentrated solution:85.68-360L/h is recommended to use DN6 (2.7-12L/min)

Roughly selecting the flow caliber for water measurementDN25、 The flow meter for measuring concentration is DN6, and the above is the measurement range required for 10 minutes of material delivery. As the small flow rate of the measuring liquid is only 85.68L/h, which is lower than the measurement lower limit of DN6, it is better to limit the delivery time to 5-8 minutes.

4Introduction to the functions of the dual two-way material distribution and quantitative control system:

1. Query of material issuance records: including the number of times materials were issued, the start and end time of each issuance, and the actual quantity of each issuance;

2. The unit and value of material issuance can be set arbitrarily, and all operations and instructions are in Chinese (depending on the nature of the customer, such as for foreign enterprises or exporting abroad, they are mostly in both Chinese and English);

3. At the same time, after inputting the density of the fluid, the feeding amount is automatically converted into volume and mass units;

4. Equipped with a status light indicator, "start", "stop", and "reset" buttons for operation, the display is intuitive and the operation is convenient. In the event of an emergency, material distribution can be paused or stopped at any time;

5. Display the total cumulative amount, number of times, time of material feeding, and the status of the control valve;

6. Material loading display interface: real-time cumulative material loading, percentage of total material loading, advance quantity (set quantity), real-time instantaneous flow rate, status indicator light, and valve status display;

7. Built in password protection function can effectively prevent unauthorized settings by other personnel;

8. Can be matched with printer function: automatically print after each feeding is completed (printing content includes: tag number can be set, feeding amount can be set, actual feeding amount, feeding time, stop time);

9. Equipped with USB interface for downloading material issuance records, with RS485, etc

5Notice for Booking Double Two Channel Material Distribution Quantitative Control System:

1. Choose the appropriate flowmeter: inform us of the name of the measuring medium, the diameter of the measuring tube, the working pressure and temperature, the flow range, or other requirements. We, Shanghai Longkui, will professionally design and select the appropriate flowmeter for you;

2. Explain the requirements for control, such as the size of each quantitative value, the number of times to control each day, whether the value controlled each time is the same, and other requirements;

3. Choose a cut-off device: If there is already a cut-off device, please inform us of its working power supply and power, and we will customize it accordingly; If needed, we can also provide a cut-off device. We suggest choosing solenoid valves or electric valves (when delayed start or stop is required) for the cut-off equipment. Do not control the pump. At the same time, when arranging the pipeline, use the stagnant flow generated by the liquid level difference as the power source. This is safer for control and has stable and accurate measurement accuracy, which can reach 0.2%

VIPrecautions for on-site installation of the dual two-way material distribution and quantitative control system:

1. Flow meter installation (see instructions for details): At least ensure that the front and rear straight pipes of the flow meter are 10D and 5D (D is the pipe diameter), and the longer the better. If there are pumps and regulating valves in front, try to increase the length of the front straight pipe as much as possible, stay away from them, and there should be no strong electric, strong magnetic, or variable frequency interference near the installation point. The installation point pipeline must be full pipe flow, and when the installation pipeline is vertically oriented, the fluid flow direction must be from bottom to top.

2. Electromagnetic valve: It should be installed behind the flow meter and at a distance of at least 40D (D is the diameter of the pipeline) from the flow meter to avoid vibration and electromagnetic field caused by the electromagnetic valve before and after operation, which may affect the measurement accuracy of the flow meter. In addition, the installation point of the electromagnetic valve should be as close as possible to the flow outlet.

3. When controlling a pump, attention should be paid to the working power supply. High power pumps need to be equipped with a frequency converter to reduce voltage and start

4. Control box: Non waterproof type, it is recommended to install indoors. If installed outdoors, waterproof measures should be taken. 【 Customization of explosion-proof type (with explosion-proof certificate), anti-corrosion type, high IP level, material and material configuration can be specified or recommended for customization 】
