【Abstract】 A thermal pulp grinding machine with a hydro-mechanical clearancecontrol servo system is an important machine for paper-making and man-madewood manufacturing. The essential principle of the clearance servo controlbetween the grinding disces was discussed in this paper, together with theor-etical analysis and calculation of the servo-control system. Some analogueapparatuses were established and the accuracy of position under constant loca-lity was measured. It is found that based on the conclusions reached in this paper,the data from the test approaches the theoretical calculation and the result isquite satisfactory. It is highly important to design and operate a hydrauliccontrol system correctly.更多还原
