DLPLQuantitative control/Quantitative feeding/Automatic feeding/Manual operation of material feeding/Automatic flow control device/Button based operation for material feeding/Quantitative canning/Replacing manual canning refers to adding a function that automatically interrupts the flow of the pipeline when the cumulative amount reaches a certain value on the basis of precise measurement of pipeline flow.

Guangzhou Dechuan Instrument Co., Ltd. mainly relies on the pulse flow signal feedback from the flow meter to the quantitative control instrument for this solutionAccumulated traffic reaches the set value(Quantitative value)The quantitative controller will give a switch signal to the solenoid valve or pump to achieve the start and stop control of the valve or pump. Realize automatic and manual control of feeding. The system has high accuracy, simple operation, and can be calibrated on site

eyeStainless steel automated quantitative control and pure water equipmentOne of the projects that many enterprises use or need to improve in the past is the combination of features such as easy to operate and learn, intuitive display, manual or automatic flow control. Especially suitable for oil field blending, water blending, drug blending, batching, quantitative water injection, and quantitative control of various liquids. Currently, some still rely on manual canning operations/For enterprises that want to improve work efficiency without investing too much cost in material production, it is recommended to adopt this system.

1、 Composition of quantitative water addition system

1Flow 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 such as the measuring medium, pipeline diameter, and flow range.

2TheDLPLControl box: It contains a quantitative display controller, internal control circuits and components, external control buttons and indicator lights, etc. The standard size of the box is400*300*200mmThe power supply isAV220V.

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

2、 Control process of quantitative water addition equipment

After receiving the flow signal from the flowmeter, the quantitative controller accumulates the flow internally and sets the required quantitative control value. When the cumulative value displayed by the quantitative controller reaches the set quantitative control value, the 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 characteristics of quantitative water addition equipment

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

2The 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;

3The control box panel is equipped with“start”、“停止”and“zero clearing”Button, and there are“status indicator light”Display, therefore intuitive, easy to operate, convenient, and easy to learn;

4The quantitative controller is equipped with a fully Chinese LCD display, and the quantitative control value can be changed as needed each time. It only needs to be operated within the quantitative controller;

4、 Main functions of quantitative water addition equipment

1Equipped with large and small valve controls, respectively controlling large and small flow rates to achieve precise quantitative control;

2When controlling both the pump and the valve simultaneously, there are functions for delaying the start of the pump and closing the valve in advance;

3Equipped with overflow and pump holding interfaces, it provides immediate protection by shutting down the feeding process in case of overflow or pump holding;

4In the quantitative control instrument, 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;

5、 Ordering Instructions for Quantitative Water Addition Equipment

1Choose the appropriate flow meter: 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 select the appropriate flow meter for you;

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

3、Stainless steel automated quantitative control and pure water equipmentChoose 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 that for the cut-off equipment, please choose solenoid valves or electric valves(When delayed startup or shutdown is required)For better control, do not control the pump. At the same time, when arranging the pipeline, it is better to use the power source that generates flow due to the liquid level difference. This ensures safety and measurement accuracy during control Quantitative control in various regions
