Quantitative control cabinet

Quantitative water addition device/automatic control quantitative canning machine/quantitative control system is particularly suitable for workshop batching, water addition, drug addition, 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 this system.
1、 System composition
1. Measurement sensors: can be flow meters installed on pipelines, level gauges on storage tanks, or weighing sensors, etc. This is the basis of control and directly affects the effectiveness of control. Therefore, the basic requirement is that the higher the measurement accuracy of the sensor, the better, and it has signal output function. At the same time, there are many types of measuring sensors, and it is important to choose the appropriate measuring sensor based on the actual working conditions on site. In addition, other technical requirements such as explosion-proof, anti-corrosion, and installation methods should also be considered.
2. HDL Quantitative Control Box: It contains an intelligent quantitative control device, internal control circuits and components, external control buttons and indicator lights, etc. The standard size of the box is 400 * 300 * 200mm (height * width * thickness), and the power supply is DC24V or AC220V optional. Sensors or cutoff devices are directly powered by the control box. And it can output 4-20mA, RS485 and other signals to other control devices, and can also add printing function.
3. Cut off equipment: It can be power equipment such as pumps, or equipment such as solenoid valves, electric valves, pneumatic valves, etc. As long as the corresponding power is specified during selection, we can customize it accordingly, or we can provide supporting equipment.
2、 Control process
After receiving the signal from the measuring sensor, the quantitative controller completes the accumulation and display inside, and sets the required quantitative control value inside the controller. When the accumulated 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 Features
1. It only requires measuring sensors, control boxes, and cutoff devices, with a simple structure and low cost;
2. The control circuits and components inside the control box are customized according to the measuring sensors 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. The flow meter and cut-off equipment are powered by the control box, and only AC220V needs to be provided to the control box;
3. The control box panel is equipped with "start", "stop", and "reset" buttons, as well as a "status indicator light" display, making the display intuitive, easy to operate, convenient, and easy to learn;
4. The 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;
