Brief description:

The multi-channel ingredient filling quantitative control system refers to the process of adding an accumulated quantity on the basis of precise measurement of pipeline flow, and automatically cutting off or controlling the pipeline when a certain value is reached. It can achieve separate control of multiple liquids.

As workers' wages continue to rise, automatic control has become a trend. At present, many enterprises use or need to improve one of the projects, which has the characteristics of easy operation and learning, directly replacing manual feeding and batching, and intuitive display of this system, combining manual control or automatic control. Specially suitable for workshop batching, water mixing, drug mixing, batching, quantitative liquid injection, and quantitative and timed control of various liquids or gases. At present, some companies that still use manual canning/feeding operations and do not want to invest too much cost to improve work efficiency suggest adopting the system launched by Shanghai Longkui.

1、 Composition of Multi channel Ingredient Filling Quantitative Control System:

1. WDK control box: It contains PLC, touch screen, internal control circuits and components, external control buttons and indicator lights, etc. The standard size of the multi-channel box is 800 * 600 * 200mm, and the input power (AV220V) is uniformly supplied to the control box. Other equipment such as flow meters and solenoid valves are directly powered inside 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. Cut off equipment: It can be an existing power pump in the pipeline; It can also be a rear mounted valve (solenoid valve, electric valve, etc.).

4. Control pump: The power part of solid or gas, and the working power supply can be DC12V, DC24V, 220V, 380V.

5. After the residual medium in the pipeline is dispensed, it can be emptied by air blowing or other emptying methods. It can also be mixed while dispensing, or mixed after dispensing (customized according to customer requirements)

2、 Control process of multi-channel ingredient filling quantitative control system:

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 internally in the PLC touch screen or controller. When the cumulative value displayed on the screen reaches the set quantitative control value, the PLC 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.

3、 Product features of multi-channel ingredient filling quantitative control system:

1. It only requires a flow meter, control box, and cutoff equipment, with a simple structure and low cost;

2. The PLC, touch screen, instruments, control circuits, and other components inside the control box can be customized according to the brand and model of the flow meter and equipment required by the customer. The signal line connection is simple, and the flow meter and cutoff equipment are directly powered by the internal control box, and generally do not need to be adjusted after arriving on site;

3. The touch screen and controller are fully displayed in Chinese, making operation convenient and the display intuitive; For export or foreign enterprise application customers, the touch screen and control instrument are displayed in both Chinese and English. The control box panel is equipped with "start", "stop", and "reset" buttons, which can also be external buttons, and has a "status indicator light" display, making the display straight, the operation simple, convenient, and easy to learn;

4. The quantitative control value can be changed as needed each time. It only needs to be operated in the quantitative control instrument (set on the software for the PLC control cabinet), or several sets of commonly used quantities can be set according to requirements. When feeding, simply select it without the need to set it again;

4、 The main functions of the multi-channel ingredient filling quantitative control system are:

1. When controlling both the pump and the valve simultaneously, there are functions for delaying the start of the pump and closing the valve in advance;

2. Equipped with overflow and pump holding interfaces, it provides immediate protection by shutting down the feeding process in case of overflow or pump holding;

3. In the touch screen or quantitative control device, the total accumulation, instantaneous flow rate, time, and input signal value of the flow meter can be viewed, and there are query functions such as feeding frequency, feeding time, feeding quantity, and daily or monthly accumulation;

4. Can be equipped with a printer for real-time printing function, including the start and end time of material printing, material quantity, actual material quantity, and material name (freely set according to customer requirements); Power off and maintain the working state before feeding.

5. PLC programming software and control instruments and control boxes are completely independently developed, so if other functions are needed, we can customize them;

5、 Display part of the multi-channel ingredient filling 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 are fully operated and explained in Chinese; (For export or foreign enterprise application customers, the touch screen and controller are displayed 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, the display is intuitive and easy to operate. In the event of an emergency, the material can be paused or stopped at any time, displaying the total cumulative amount, number of times, time, and status of the control valve;

5. Material loading display interface: real-time cumulative quantity of material loading, advance quantity (set quantity), start and end time of material loading;

6. Equipped with password protection function, it can effectively prevent other personnel from making mistakes;

7. Can be paired 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);

8. Equipped with emergency stop and USB download of material issuance records, power-off hold function, with RS485, etc;

6、 Ordering instructions for multi-channel ingredient filling 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, and we will provide you with a matching selection;

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 cutoff device: If you already have a cutoff device, please inform us of its working power supply and power, and we at Longkui will tailor it for you; If you need us, Longkui can also provide cut-off equipment. We suggest choosing solenoid valves or electric valves (used when the pump is delayed in starting or closing) as 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, which is safer and has higher measurement accuracy during control.

7、 Precautions for installation of multi-channel ingredient filling quantitative control system:

1. Flow meter installation: Ensure that the straight pipes in front and behind the flow meter are as long as possible. If there are pumps and regulating valves in front, try to increase the length of the straight pipes as much as possible and keep them away from them. There should be no strong electrical, magnetic, or 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 】
