ApplicationsElectric boiler controlThe electric boiler control system realizes the fully automated control and all-round monitoring of the electric energy environment-friendly boiler. The whole system is controlled by PLC, with manual/automatic working condition selection function. It can detect boiler pressure, boiler temperature, and flow rate according to system requirements, and start and stop the output of the upper and lower limits of pressure and temperature, control the switching of heating resistors, and automatically eliminate them. Failure, etc., to ensure the normal, safe and reliable operation of the electric boiler.
Two 4-20mA and two PT100 inputs are needed in the system. 2 channels 0-10V output, 7-inch touch screen display operation, so choose HMIT-20M20R-3PT4AD-2DA model all-in-one machine.
Constant pressure water supply systemLarge-scale water supply and drainage systems are widely used in industrial and agricultural production, daily life, etc. These large water supply and drainage systems are often not composed of one pump, but composed of multiple pumps. How to realize these large-scale water supply and drainage systems controlled by multiple pumps This program introduces a multi-pump constant pressure water supply control system based on the multi-pump constant pressure water supply control unit of the Kewei color all-in-one machine (HMIT-20M20R-3PT4AD-2DA).
The structure of Gongduogaochumu's water supply control system is shown in the figure below, which consists of multiple pumps, pressure sensors, constant pressure water supply control units, and frequency converters. The pressure sensor will detect the pressure change in the pipeline at any time, and send the detected analog signal to the constant pressure water supply control unit. After the water supply control unit compares and judges with the set pressure, it controls the inverter to automatically adjust the speed of a certain water pump With the input and withdrawal of multiple water pumps, the pipe network can be maintained at a constant set pressure value, which meets the requirements of users and keeps the entire system in the best state of high efficiency and energy saving. If the water consumption is very small, the main water supply system will be automatically stopped after analysis and confirmation by the constant pressure water supply control unit, and the dormant pump will be activated to maintain the pressure of the pipe network and a small amount of water. When the water consumption reaches the dormant pump cannot maintain the set pressure, the main The water supply system starts automatically, and the dormant pump stops running, which improves the safety of system operation and obtains obvious power-saving effects.
Pay Attention!The touch screen all-in-one machine is a human-computer interaction device that integrates computer technology, multimedia technology, audio technology, network technology, industrial plastic arts and mechanical manufacturing technology. Users only need to tap on the screen to get the information they want.
If you observe carefully, you will find that all-in-one touch screens are already everywhere in daily life. Especially in banks, large shopping malls and other places, they must be indispensable. So in terms of office scenarios, what are the advantages of a touch screen all-in-one?
1. The touch screen all-in-one machine can realize wireless screen projection, which means that there is no need to spend time connecting and debugging equipment. Everyone can screen content to the touch screen all-in-one machine through their laptop, mobile phone or tablet. Turn on the comment function to comment on the displayed page along with the page. Wherever you need to draw the key points in the PPT, just use a pen to draw directly on the screen.
2. Another function of the touch screen all-in-one machine is smart writing, which allows you to write smoothly on the touch screen with a writing pen. With the boundless writing space, there is no need to write, write and erase like a whiteboard, the process becomes compact, people's attention and thinking rhythm will not be easily disrupted, and the efficiency will naturally become higher. You can also create a new page for smart writing, and the meeting record can directly generate a QR code, which can be taken away by scanning the code after the meeting.
3. The touch screen all-in-one machine can conduct video conferences, saving a lot of time and cost on business trips.
4. From the perspective of long-term development, intelligent office is the trend of social development. It can be predicted that the functions of the touch screen all-in-one machine will continue to improve.
Finally, I will introduce the precautions for using the touch screen all-in-one machine:
1. The touch screen part is made of glass, and the corners of the glass are relatively sharp. Gloves/finger cots are required for assembly.
2. The touch screen is made of fragile glass. Do not apply strong impact to the touch screen during assembly.
3. Single-chip operation is required when picking and placing the product, and handle with care to avoid the product from colliding with each other and scratching the surface of the product.
4. When cleaning the surface of the product, please wipe with a soft cloth (deerskin) dipped in petroleum ether.
5. Do not stack touch screens.
6. Do not use corrosive organic solvents to wipe the surface of the touch screen film, such as industrial alcohol.
