Process control is the abbreviation of automatic control of production process, which is an important part of automation technology. Usually refers to the production process of oil, chemical, electric power, metallurgy, light industry, building materials, nuclear energy, etc. In modern industrial production process, process control technology is to achieve optimal technical and economic indicators, improve the economic benefit and labor productivity, improve working conditions, protect the ecological environment plays a more and more important role.
In process industry automation and information system as the main line, the key technology and equipment system we design and production process control professional laboratory comprehensive practice teaching equipment, set up the theme of the major laboratory engineering practice base.
This training unit design is reasonable, the versatility, not only can satisfy this, industrial automation, automatic control and so on the specialized subject of professional courses related to the requirement of experimental teaching, but also suitable for graduate students on topics in the research and development.
features
Adopt industrial aluminum profile frame, transparent structure design, open interface. This system adopts desktop installation, tabletop type installation, flexible placement, operation table with computer placement.
The product USES the table structure, the aluminum alloy frame design, control object and control system design, fission can combine both put on the work station, and can according to need to separate use, for example: adding control system to different simulated load hanging box, can become the PLC training device, greatly increased the flexibility of equipment used.
The device input/output interface has good compatibility, drive unit and PLC control unit adopts hanging box model, it can easily be replaced the, can be used as electronic circuit of the load, and can be as the execution object of PLC control system, and according to the need to extend the upgrade.
The temperature, flow, liquid level, pressure and components of the industry are widely used, which can be used for the detection of sensors and sensors.
The idea of time-sharing control can be used to collect two or three parameters at the same time. For example, a set of measuring flow and a set of temperature measurement. Object system adopts the whole aluminum alloy production, and engineering concepts to aesthetic point of view, look at the object system, creating process and equipment professional laboratory experiment, it built a modern demonstration laboratory.
The basic control device can complete process control training program, implementation of flow rate, temperature, pressure, liquid level, composition of 5 kinds of parameter control and PID regulating function, and can achieve the goal of a variety of teaching practice.
Adopt low pressure water pump, water pump outlet has regulating valve loop and direct loop, can choose to use according to experiment requirement.
All instrument sensor wiring is directed to the terminal, and the sensor circuit can be selected according to the required data, and the sensor and instrument can be flexibly matched according to the experimental content.
Device input/output interface has good compatibility, drive unit and the main control unit are all made of hanging box pattern, can easily be replaced, can be used as electronic circuit of the load, and can be as the execution object of PLC control system, and according to the need to extend the upgrade.
The electric control adopts AB 2080-LC50 PLC, which has the components of analog expansion module and other related devices, and controls the mainstream configuration for the small industrial equipment process.
