Pneumatic Double-disc Grinding Beating Control System Reliability, Economy

With high-speed paper machine and application in the whole papermaking procedure of DCS collecting and distributing control system in recent years. In order to meet the question that automatically control and capacity of electrical machinery is expanding constantly. The Pulp refining process adopts DCS and 6KV control system, is a kind of advanced control project. Adopt the computer to protect and remote control and operate system. Realize the automation of control, not only improve the quality of refined-pulp, respond to the request that pulp refining continuous , but also lighten the stuff's work load , the purpose to achieve high-efficient economy, Have wide value to popularize. But the characteristic to its control system is still relatively few at home in research . Subject this through to pulp refining control system atmospheric pressure refiner for research object because of DCS and 6KV, analyse its control characteristic, carry on analysis and research from dependability and economic respect, carry on the feasible scheme that analyses and proposes solving the problem to the existing problem of the control system deeply, establish the foundation for setting up control system optimization design in the future, in order to improve and control such craft parameters as the precision ,etc, improve product quality further at the same time, is it pulp refining dependability of control system offer the theoretical foundation to improve.This subject summarizes forefathers' research results on the basis of the thing that read domestic outside about documents extensively, to the complexity of its structure, through the theory analysize , study the structure characteristic of atmospheric pressure type refiner control system, refiner mechanism, technological process, control scheme, etc. to refiner dependability and economic influence of refine etc. to control system various kinds of parameter, through the theoretical research , put forward the possible technological measure and does not disc refiner of practical problems worn and torn normally by reducing , perfect the existing procedure and controls , perfects the disc refiner protect , proposes the actual design plan , reach operating reliably and best economic benefits. According to the basic principle of dependability, structure characteristic of analyticl system, set up on the basis of DCS and 6KV atmospheric pressure refiner dependability block diagram model of control system of pulp refine etc,go on dependability analyse and calculate, find out its key equipment from it. put forward the measure of improving systematic dependability. Probe into DCS and 6KV and control the impact on its dependability . economic performance of the scheme, thus find out optimum design and improve , to refine design plan of control of control system , put forward the suggestion of consulting at the same time.
