① 如图所示为三种液体混合装置，SQl、SQ2、SQ3和SQ4为液面传感器，液面淹没 时接通，液体A、B、C与混合液阀
最近没空。，。。如果有时间等的话到12月中给你弄
② 三种液体混合PLC编程
呵呵，跟我们课本上的一模一样。
③ 我现在想用组态王里的PID控件， 三种液体A酸性，B中性，C碱性, 加入一个容器中D， 三种液体三个变频器控制
首先，三种原始液体需要将两种设为定值，一种设为调节。
因为PID的原理是通过目标值与实际值的偏差来进行输入值的调节，只能调节一个，不能同时调节三个。
其次，做PID调节，周期恒定是前提，组态王运行在WINDOWS环境下，不能保证精确的周期。组态王的PID调节只适应于周期很长的环境，而且是精度不高的。建议用PLC或其他硬件来实现PID调节。
④ 摘要翻译，不要工具翻译的
With the development of economy and the progress of the society, requirements for automatic instrial proction continued to improve. In medicine, food, chemical instries, often need to put more dangerous liquid toxic, flammable and explosive necessary processing in time and in the right conditions so as to obtain a proct, but these processes have been carried out in human monitoring or manual operation, so that the working environment is very bad. The design of the main use of PLC to achieve the control device and the configuration of the three kinds of liquid mixture as an example, device parameter set through PLC automatic mixed automatic operation completion fluid, reces the risk of manual operation. This paper introces the basic design requirements of various liquids automatic mixing and technical analysis, and also introces the control technology of PLC and configuration, and mainly on the "design of the automatic mixing device control and configuration of various liquid" PLC implementation is analyzed and discussed based on. The instrial design using programmable logic controller (PLC) and configuration (Configure) automatic control technology to solve instrial monitoring a variety of automatic liquid mixing control problems. Using a combination of PLC control and configuration monitoring technology, to realize the automatic process of three or more liquids in certain proportion are added in mixing, stirring, heating device and emissions. The design of the three kinds of liquid mixture as an example, the main elements of the design include: analysis and design of electrical principle diagram of process analysis and arrangement, device control and configuration of the design, hardware connection and connection, the trapezoidal chart analysis and design, design and analysis of defects and its situation. After a number of debugging and modification, the design realizes the automatic add liquid, automatic mixing, automatic heating and automatic control function of multi liquid mixing device, but also realizes the manual and automatic switch or a combination of function. In addition, this paper also discusses the difficulties encountered in the design, the design of the shortcomings and the foreground of the design.
⑤ 力控组态软件 液体自动混合装置的监控系统 请给我完整的 谢了
这个要花时间来做的， 也是人都要吃饭，
⑥ PLC设计液体混合装置.设计
设加入氧气体积为X
27.72+X=（396+X）*0.21=70.18 结果依然是如我上面所得出的结论：70.18
虽然我之前做的不严密 但是此问题还没有要求严密到需要考虑到除氧气氮气外的其它气体
⑦ 液体混合装置的PLC控制系统 求论文设计
用步进指令写吧，比较简单。网上有很多这样的例子，你可以找找，如果找不到我发给你！
⑧ 多种液体自动混合控制系统在国内外的发展前景怎么样
前景非常广阔，在各行业都有所体现。例如：在化学中往往需要将两种或两种以上的液体混合均匀，才能实现正常的实验需求。在混合油漆等化学用品时，需要混合均匀才能实现好的效果，而人工却不能实现。
