Quantitative control is the key link of papermaking, the quality of material discharge directly affects the quality and pass rate of paper forming paper. The control accuracy of electric material door is one thousandth, can fine- tune the material door, so as to accurately control the quantitative. Electric door repeat accuracy is high, in the paper machine to change different varieties, easy operators will be the door one step to adjust in place, reduce loss of paper / reduce costs. System composition: electric door has electric adjustment quantitative valve and valve controller composition.
In a paper mill, it is very important to detect the flow of pulp entering the head box. This flow parameter directly participates in the control of the paper quantification. Due to changes in head box pressure and liquid level, the amount of pulp jetted onto the mesh through the lip plate will fluctuate. Therefore, controlling the stability of the head box pulp flow is vital to the control of the paper basis weight, and it will also directly affect the paper's quality. The final quality.
Through the measurement of the thickness and moisture of the final finished paper, the flow of pulp is controlled, which is called the "quantitative control system", and is usually considered to be the most important part of the paper machine "QCS" system.
The measurement of pulp flow usually uses electromagnetic control valve system.
Because of its structural characteristics, it is suitable for the control of related process parameters in the suspension medium containing fibers or small solid particles in papermaking, chemical, metallurgical and other industrial enterprises. It is especially suitable for the pulp in the pulping and papermaking production process. , White water, black liquor, white liquor and other suspended particle fluids and the automatic adjustment of thick and turbid slurry fluid media.
