Comprehensive experimental device of distribution process control

Comprehensive experimental device of distribution process control,Mine power supply simulation system experimental device

I. Overview

The distribution process control comprehensive experimental device (Process Control System (PCS) is a common physical quantity in the production process of modern industrial production, such as temperature, pressure, flow, liquid level and other parameters. Features, teaching experimental equipment with laws of research process control, process control comprehensive experimental devices use intelligent industrial instruments, which are close to industrial reality, use safety, stable operation, simple m--ntenance, and superior cost -effectiveness. This device integrates a variety of control methods, reappears the control methods used by actual industrial site, and provides users with more friendly development interfaces.

(1), can meet the "automatic adjustment principle", "process control", "control instrument", "automatic detection technology and sensor", "computer" and related courses in teaching experimental needs;

(2) Experimental and tr--ning experimental equipment that can be used as related corporate technical personnel, instrument operators, and system operation monitoring staff.

2. Product structure and characteristics:

(1) Configuration of the three water tanks; double road water supply system.

(2) The experimental cabinet is completely opened, and the internal devices are all visible, which is conducive to teaching and m--ntenance.

(3) Humanized design, equipped with a water storage tank, inlet dr--nage self -control device to reduce the labor intensity of the experimental personnel. The hanging rack with a dedicated line is convenient, clean, and beautiful. Provide conditions for experimental civilization operations.

(4) The instrument and components of the device are used in modern technology industrial -grade products, and the degree of intelligence is high. Good accuracy and diverse specifications. It is good for intuitive teaching and broadening the knowledge of students' industrial field. Lay the strong foundation for the future.

(5) High degree of safety, the system is equipped with leakage protection, a special experimental power supply with a protective cover, and the temperature control box to prevent water -free heating and automatic control.

(6) Good openness. Under the guidance of teachers, students can observe, participate in the operation by themselves, proof themselves for verification, and analyze theoretical analysis according to the real -time curve of the record.

(7) Boiler heating program control protection system

A. The boiler heating inner bile is protected by the water level liquid level. The water level does not reach a cert--n height, and the control system cannot control the work of the compressor of the compressor.

B. The power control switch of the electric heating pipe is a key switch. When not experiment, the teacher protects the key to avoid miscalculation of unrelated personnel.
