MR171E Full Study On Regulation Bench Process Control Trainer Educational School Laboratory Equipment
1 Product overview
1.1Overview
Process control is the abbreviation for automatic control of production process, which is an important part of automation technology. Usually refers to the continuous or automatic control of the production process in the industrial production of petroleum, chemical industry, electric power, metallurgy, light industry, building materials, nuclear energy and so on. In the modern industrial production process, process control technology is playing an increasingly important role in achieving various optimal technical and economic indicators, improving economic benefits and labor productivity, improving labor conditions, and protecting the ecological environment.
Taking the key technologies and equipment systems that embody the automation and information systems of process enterprises as the main line, we design and manufacture comprehensive practical teaching devices for advanced process control professional laboratories, and establish an engineering practice base for this professional subject laboratory.
This training device is reasonably designed and has strong versatility. It can not only meet the experimental teaching requirements of related courses in industrial automation, automatic control and other majors, but also be suitable for postgraduate research and development of topics.
1.2Features
1.21 Adopt industrial aluminum frame, transparent structure design, and open interface. With universal wheels at the bottom, each unit can be coordinated flexibly, easy to use, and not easy to damage.
1.22 This training device includes a PLC touch screen all-in-one machine and a button control unit, which can switch between hand and self without affecting each other. It is the mainstream configuration for small industrial equipment process control, which greatly increases the flexibility of equipment utilization.
1.23 The temperature, flow, liquid level and pressure detection and sensing devices widely used in industry can be diversified and related experiments can be designed.
1.24 The idea of time-sharing control can collect two or three parameters at the same time, for example, one set of flow measurement and one set of temperature measurement. The object system is made of all-aluminum alloy. From an aesthetic point of view and without losing the concept of engineering, the experimental object system of the process equipment professional laboratory is reviewed and built, and it will be built into a demonstration laboratory with the atmosphere of the times.
1.25 The device can complete the basic control training items of process control, realize the control of the four parameters of flow, temperature, pressure, and liquid level and PID adjustment functions, and can achieve a variety of teaching and training purposes.
