D new virtue of paper machine wet end independent control system
D virtue has launched Valmet Stand - u.s Retention Control (Valmet RET, d virtue Retention of independent Control) of the new Control system.Flow in the system to keep the rate as well as the broken paper pulp slurry ash product to control box.It to the paper, paper board and household paper manufacturers provide a wide range of advantages.Before these advantages only in the use of process control and Valmet Valmet DNA IQ was not apparent until the quality management system.
Using Valmet Retention Measurement (Valmet RM3, d Measurement) Retention of virtue, has the first-class model predictive control of low concentration Measurement and control equipment, makes the control of paper machine wet end onto a new stage.
D virtue automation product managerTimo RantalaSaid: "two sets of control system based on Valmet IQ Optimizer MD Optimizer, which owns the supply of good record.As is known to all, in almost all kinds of production process, the paper wet end stability to improve the performance of the machine and the product quality, reduce consumption of chemicals and energy, is crucial."
Rapid flexible wet end control can improve the process stability and running
Valmet RET can reduce paper quantitative, ash and moisture fluctuations, thus improve the quality of longitudinal paper picture.Other advantages include reducing wet end of paper, reduce the dosage of chemicals and dry steam in the process of the boot and the manufacture and better control.All of which help to increase production.
As a new system of the first user points out: "keep the rate of measurement and control is an extremely reliable solutions.Two systems in the course of continuous use.Arguably, these has become our standard machine."
Technical information about the retention of control system
Valmet RET retention of control system designed to reduce the concentration fluctuation of short cycle system, and ensure the stability of the wet end run.Using of retention aid flow control, stability of white water concentration.
Convection pulp box is broken during paper slurry ash product control, its purpose is to maintain the stability of paper ash product picture, so as to simplify the process of paper, shorten downtime, and after the recovery operation, immediately make paper ash product to achieve the target.Broken paper occurs, the automatic control system is up and running.
Two sets of control are installed in the cabinet room d virtue in the hardware, can shorten the delivery time, accelerating the implementation of the mill project and equipment debugging process.In a safe way with Valmet RET system remote connection, to insure the service center from d virtue all over the world quickly take measures to provide remote support to customers.Connection with mill system can use the standard 4.20 mA interface or other digital link.
