Supplied by Jiangsu Aoke Instrument Co., LtdQuantitative control issuing system AK-DLKZAdopting a backlit LCD Chinese display, the Chinese LCD display has many advantages such as easy operation and intuitive data reading, which cannot be matched by digital display instruments. Of course, the price is slightly higher than that of digital display instruments.

Quantitative control issuing system AK-DLKZFeasible functions

The quantitative control instrument system is composed ofFlow meter, quantitative flow controller, solenoid valve, and distribution boxWaiting for device composition. 1.External start, stop, and reset buttons are available.

2.Can simultaneously control the opening of valves and pumps.

3.Adjustable8A commonly used quantity.

4.Power off, restart and continue to measure according to the previous quantitative value.

5.Can query quantitative frequency, quantitative value, and quantitative time.

6.Installing a micro printer can print quantitative data.

7.Full Chinese LCD display, easy and convenient to operate.

8.Can install size valves to control quantitative control, with more precise accuracy.

The above characteristics cannot be achieved simultaneously by other quantitative control instruments. The quantitative control instrument is absolutely perfectly configured and can change the internal program according to user requirements to make the operation more in line with on-site requirements.

Can be implemented forQuantitative measurement, quantitative filling, and quantitative batching of fluidsControl of the waiting process. The structure is shown in the figure.

Quantitative control issuing system AK-DLKZPrinciple:

At the beginning of quantitative measurement, the flow quantitative control instrument indicates that the solenoid valve is open and the fluid enters the flow sensor. flow sensor

Send the flow signal to the quantitative integration control instrument and start measuring. When the flow reaches the set value, the quantitative integration control instrument sends out a signalDisconnect the solenoid valve and restore it to its initial closed state.

Quantitative control issuing system AK-DLKZTechnical Requirements

For example, adding a certain amount of water to the jar (such as10L）Input on the flow integrator (quantitative controller)10LThe quantitative value,

Then press the start button (or confirm button), and the flow accumulator relay will close（The solenoid valve is open, and the water filling light is on）,

The flow accumulator begins to accumulate, and when the accumulated amount reaches10LAfterwards, the relay of the flow integrator was disconnected（The solenoid valve is closed, add

Water light off）,This quantitative completion.

If you want to perform the next quantitative control, you need to press the reset button and then follow the above steps. If necessary

To pause, press the stop button. If the quantitative value is consistent with the last time, simply press the start button.

Quantitative control issuing system AK-DLKZRequirements:

The input of the controller is4-20mAOr pulse signal, with external start, stop, reset, and two relay outputs.

An intermediate relay needs to be added from the relay to the solenoid valve. If the solenoid valve is24VPower supply, an additional one is needed24Vswitch

Power Supply.

Note: Indicator light, button, intermediate relay, air switch, AC contactor (optional), quantitative controller (LCD)

Display, control box, form a control system to control the site（24VDC）To start or stop the solenoid valve, an additional one needs to be added

The main power switch, flow meter, and solenoid valve need to be made according to the on-site requirements.（Accessories can be customized by users themselves）

1. Characteristics of quantitative control system

1. Accurate control can be achieved, and parameters can also be set for fine-tuning. The constant value controller is fully displayed in Chinese, with prompts for operation and independent buttons, making it easy to operate and set.
2. High degree of automation, accurate precision, fast speed, and the ability to simultaneously quantify multiple feeding devices.
system requirements
1. Single channel material dispensing requires a single pump and valve to maintain a constant pressure throughout the entire pipeline, in order to ensure the accuracy of the entire system. Minimize pipeline vibration as much as possible.
2. The accuracy of the entire system depends on the flow meter. Choosing a high-precision flow meter is necessary to ensure the overall barrel accuracy. It is recommended to use a turbine flow meter for this system.

Below is an explanation of the control method for everyone:

Measure the flow rate through a flowmeter, control the instrument to receive signals, and set the quantitative value in the control instrument. After the quantitative value is reached, the solenoid valve and water pump will shut down and stop working.

The functions of several switches in the instrument box:

System startup: After setting the required quantity, press this button to automatically open the solenoid valve and measure the medium through the pipeline.

System stop: The system can be stopped at will during operation.

System recovery: It can restore to the previously set quantity.

System reset: Accumulated amounts can be reset to zero.
Let me give you an example: Now we need to quantify 100m3 of water. The first step is to set the volume in the instrument to 100m3. Press the system start button, and then the solenoid valve, water pump, and flow meter will start working. The display will start counting down the cumulative value of the control instrument. When the volume reaches 0 from 100m3, the solenoid valve and flow meter will stop working.

If you want to start again next time, press System Recovery, and then press System Start.

Quantitative control issuing system AK-DLKZFeatures:

1The control circuits and components inside the control box are customized according to the flow meters and equipment required by the customer. The signal lines are easy to connect and generally do not need to be adjusted upon arrival at the site;

2The control box panel is equipped with“start'、“停止'Waiting for the button and having“status indicator light'Display, therefore intuitive, easy to operate, convenient, and easy to learn;

3Each quantitative control value can be changed as needed, simply by operating within the quantitative control instrument;

4The display parameters of the quantitative control instrument include current accumulation, total accumulation, instantaneous flow rate, time, input signal value of the flow meter, etc;

5Equipped with large and small valve controls, it can respectively control large and small flow rates to achieve precise quantitative control;

6It has a material loading query function, which can query the total number of material loading times, each loading time, each loading quantity, etc.
