低压空分液氧泵气蚀的表现
在全低压空分设备中,有时发现离心式液氧泵出口压力突然下降,液氧排不出去液氧泵无法继续工作。常常称此现象为“带气”,这种液氧泵“带气”的现象,专业术语叫做“汽蚀”。2液氧泵产生气蚀现象的原理
因素一、当液体的压力低于相对应的饱和蒸气压力时,液体就要汽化。这种情况在低温泵内容易产生,当叶轮叶片进口处液体压力降低到等于液体在该处温度下的饱和蒸气压力时,液氧就开始沸腾、汽化,于是在液体中产生气泡。夹带着气泡的液体沿叶轮离心力方向流动,当它到达叶轮内压力升高的区域时(即气泡外面的压力高于相应的汽化压力区域)、蒸气又重新冷。由于气泡外面的压力很大,故在气泡凝结时,周围的液体以很高的速度冲向气泡所占有的空间,在该区域叶轮的表面上产生局部冲击作用(即发生强烈的水击现象)。这就是通常所称的液氧泵的汽蚀现象。因素二、当主冷凝蒸发器压力降低或液氧进口过滤器堵塞、进口管道阻力增加时,也可能发生汽蚀现象。
3液氧泵汽蚀的危害性。
汽蚀对液氧泵的影响随着它的程度不同而有差别。当汽蚀程度不严重时,其影响不大。如果汽蚀达到一定程度,工作轮叶片进口处产生的气泡很多,这些气泡随着液体进入压力高的地方(工作轮出口处)又凝缩成液体,气泡即迅速破裂。由于气液的密度差几百倍,当液氧凝缩时,体积突然缩小,周围的液体以很高的速度冲向气泡位置,使与气泡相接触的叶轮表面受到猛烈冲击。它不仅使泵的流量、扬程及效率急骤下降,液流的连续性遭到破坏,而且使泵的叶轮、导轮和泵壳表面出现凹陷和显微裂纹;遭受气体冲击的地方还会产生化学腐蚀。因此要全力避免液氧泵出现汽蚀现象。Industrial control refers to industrial automation control, which is mainly realized by the combination of electronic, electrical, mechanical and software. That is industrial control, or factory automation control. It mainly refers to the use of computer technology, microelectronics technology and electrical means to make the production and manufacturing process of the factory more automatic, efficient, accurate, controllable and visible.



Industrial control computer is a general term for tools that use bus structure to detect and control the production process, electromechanical equipment and process equipment. It has important computer attributes and characteristics, such as computer CPU, hard disk, memory, peripherals and interfaces, real-time operating system, control network and protocol, computing power, friendly man-machine interface, etc. The main categories of industrial computers include IPC (PC bus industrial computer), PLC (programmable control system), DCS (distributed control system), FCS (Fieldbus System) and CNC (numerical control system). Everyone who studies electronics knows that PLC is a very important device and a relatively difficult technology. It is a digital operation electronic system specially designed for application in the industrial environment. It is the basis for realizing industrial automation and Internet of things control. It has a very broad application prospect in the future.

PLC technology originated in the United States



PLC technology originated in the United States. General Motors of the United States was the first to apply PLC. In the 1960s, when they adjusted the factory production line, they found that the relay and contactor control system was difficult to modify, large in size, noisy, inconvenient to maintain and poor in reliability. Subsequently, the American digital equipment company developed the first programmable controller, which has achieved remarkable results in the production line of general motors. Later, PLC technology was developed in Japan and Europe, and programmable controllers were successfully developed in Japan and Germany. In 1974, China also began to study programmable controllers and widely used in various fields.



PLC first replaced the mechanical switch device, and then the function of PLC gradually replaced the relay control board. Modern PLC has more functions, and its purpose extends from single process control to the control and monitoring of the whole manufacturing system.



Application of PLC technology in industrial automation, Internet of things control and other fields



At present, PLC technology is widely used in industrial automation, automotive electronics, transportation, Internet of things control and other industries. Its role in these fields can be roughly divided into four categories.



1、 For various motion control



PLC controller is a kind of digital electronic equipment with microprocessor. It is a digital logic controller used for automatic control. It can load control instructions into memory for storage and execution at any time. The programmable controller is modular composed of internal CPU, instruction and data memory, input and output unit, power module, digital analog and other units. PLC controller can be used to control circular motion or linear motion. Nowadays, almost all the main PLC controller products have motion control function. It is used in various machinery, machine tools, robots, elevators and other occasions.



In terms of control mechanism configuration, in the early days, it was directly used for switching value i/o modules to connect position sensors and actuators. Now, special motion control modules are generally used, such as single axis or multi axis position control modules that can drive stepper motors or servo motors.



2、 Realize industrial process control



As an industrial control computer, PLC controller can compile various control algorithm programs to complete closed-loop control. In industrial process control, PLC is mainly used for closed-loop control of analog parameters such as temperature, pressure and flow. All large and medium-sized PLCs have PID modules. PID regulation is a regulation method commonly used in general closed-loop control systems. At present, many small PLC controllers also have this function module.



3、 Realize relevant data processing



Modern PLC controller has the functions of mathematical operation, data transmission and conversion, and can complete data collection, analysis and processing; These data can be compared with the reference values stored in the memory to complete certain control operations, and can also be transmitted to other intelligent devices using the communication function. In large-scale control systems, such as unmanned flexible manufacturing system, PLC controller is one of the core components.



4、 PLC communication and Internet of things



As the general trend of industrial Internet of things, the relevant technologies of PLC communication and Internet of things will be popular in the future. General PLC controller communication includes communication between PLC controllers and communication between PLC controller and other intelligent devices. With the development of industrial control automation, all PLC controller manufacturers attach great importance to the communication function of PLC controller, and have launched their own network systems. New PLC controllers have communication interfaces, which is very convenient for communication.

Three characteristics of future PLC Technology



1. Miniaturization and integration are getting higher and higher: with the requirements of the market for miniaturization and integration, PLC technology is more integrated into industrial, automotive, communication and other products. PLC products are characterized by control and data processing. While meeting the functions, the process requirements are more refined.



2. Intelligent PLC technology: with the development of AI technology, more products are endowed with intelligent functions, and PLC is no exception. For example, the intelligent i/o module of PLC used in industrial control and the intelligent temperature control module used in automobiles will have more application scenarios in the future.



3. Diversified PLC technologies: including PLC related programming languages and tools. With the deepening of application scenarios, one or several programming languages cannot achieve all functions, customized PLC products will increase, and PLC modular technologies will also increase.



Great potential of PLC market in China



Today, PLC technology is developing rapidly. According to statistics, there are more than 300 PLC manufacturers and more than 500 PLC products in the world. The United States, Europe and Japan are the main production places, with a market share of more than 60%. There are A-B companies, general electric and Modicon in the United States; Siemens and AEG in Germany; Te company in France; Mitsubishi, Omron and Panasonic in Japan are all famous PLC suppliers.



In recent years, with the attention of the state and enterprises, China's PLC industry has maintained rapid growth, and there have also been some influential enterprises in China, such as Delta, Huichuan, Hexin, Yiwei, Kewei and Lishi. According to relevant data, the scale of China's PLC market in 2017 was 10 billion yuan, and it is expected to maintain a growth rate of 20% in 2018. Domestic PLC products have very good cost performance and service, which has brought them a good reputation and market.
