系列流量定量控制系统与各类流量传感器、变送器配合，实现定量灌装、配料控制。 DLPL series flow quantitative control system cooperates with various flow sensors and transmitters to achieve quantitative filling and batching control. 点开关量输入，用于启动，恢复，以及每次累积值清零3点控制输出，用于大阀、小阀分级控制和瞬时流量下限报警变送输出可将瞬时流量值以标准电流、电压形式输出，供其它设备使用。 Main technical features: Suitable for current and pulse output flow sensor 3- point switching value input, used for start-up, recovery, and 3- point control output every time the accumulated value is cleared, used for large valve, small valve stepped control and instantaneous flow lower limit alarm The transmission output can output the instantaneous flow value in the form of standard current and voltage for use by other equipment.
定量值) ，定量控制仪会给电磁阀门或泵一个开关信号，已达到对阀门、泵的启动和关闭控制。 The flow quantitative control system is mainly based on the pulse flow signal fed back to the quantitative controller by the flow meter. When the cumulative flow of the flow reaches the set value ( quantitative value ) , the quantitative controller will give a solenoid valve or pump a switching signal, Pump on and off control. Realize automatic and manual control of feeding.
打料，同时也不想投入太多成本，就想提高工作效率的企业建议采用本系统。 At present, many companies will use or need to improve one of the projects, especially some still use manual canning / beating, but also do not want to invest too much cost, and companies that want to improve their work efficiency recommend this system. The system has high accuracy, simple operation, and can be calibrated on site.
I. System composition
、流量计：这是控制的基础，直接影响控制的效果，因此基本要求是测量精度越高越好，有信号输出功能。 1. Flow meter: This is the basis of control, which directly affects the effect of control. Therefore, the basic requirement is that the higher the measurement accuracy, the better, with a signal output function. At the same time, there are many types of flowmeters, and they should be selected based on parameters such as measurement medium, pipe diameter, and flow range, and select the appropriate flowmeter.
、温度传感器：可现场测量介质的温度，由定量控制仪根据温度变化而引起的误差自动补偿(可选) 2. Temperature sensor: The temperature of the medium can be measured on-site, and the error caused by the quantitative controller to automatically compensate according to temperature changes ( optional )
、定量控制仪：定量控制参数设定，介质的流量显示、积算、运行等 3. Quantitative controller: setting of quantitative control parameters, flow display, accumulation and operation of media, etc.
、控制箱：内部控制线路及组件、外部控制按纽和指示灯等。 3. Control box: internal control circuits and components, external control buttons and indicators, etc. 可选) ( Optional )
、断流设备：可以是管道已有的动力设备，如泵；也可以是后装上去的电磁阀等。 4. Flow-cutting equipment: It can be the existing power equipment of the pipeline, such as a pump; it can also be a solenoid valve installed afterwards.
After receiving the flow signal from the flow meter, the quantitative controller completes the accumulation of the flow inside it, and sets the required quantitative control value inside the controller. When the cumulative value displayed by the quantitative controller reaches the set quantitative value, When the control value is reached, the quantitative controller outputs a switching signal. At this time, the switch signal is used to control the interruption equipment installed on the pipeline through a matching relay or contactor, so as to achieve the effect of quantitative control.
、控制箱内的控制线路及组件是根据客户所需要的流量计和设备量身定制的，信号线连接简单，到现场后一般无需调整； 1. The control circuit and components in the control box are tailored to the flowmeter and equipment required by the customer. The signal line is simple to connect and generally does not need to be adjusted after arriving at the scene;
、控制箱面板设有“启动” 、 “停止”等按键，并有“状态指示灯”显示，因此显示直观，操作简单、方便、易学； 2. The control box panel is provided with buttons such as " Start " and " Stop " , and has a " status indicator " display, so the display is intuitive, the operation is simple, convenient and easy to learn;
、每次定量控制值可以根据需要任意更改，只需在定量控制仪内操作完成； 3 , each quantitative control value can be arbitrarily changed according to needs, just need to complete the operation in the quantitative controller;
、定量控制仪显示参数包括本次累积、总累积、瞬时流量、时间、流量计输入信号值等； 4. The display parameters of the quantitative controller include the current accumulation, total accumulation, instantaneous flow, time, input signal value of the flow meter, etc .;
、设有大小阀控制，分别控制大流量和小流量，达到精确的定量控制； 5. Equipped with large and small valve control to control large flow and small flow respectively to achieve precise quantitative control;
、设有打料查询功能，可查询总打料次、每次打料时间、每次打料量等 6.Equipped with inquiring function, which can inquire the total infeed times, each infeed time, each infeed amount, etc.
