Розробка адаптивного приводу для конвеєра із змінними вантажопотоками

Abstract

By research of improving mathematical model was established the effectiveness of usage of the new control system of hydraulic drive of belt conveyor with variable cargo flows, which enables to set operation modes. Also the influence of the typical volume of the second hydraulic motor, relationships sealing areas ratio of closing element, plunger mass and damping coefficient of control systems and hydraulic drive on dynamic processes of hydraulic system was established. As sensor in the control device was confirmed the effectiveness of usage a direct valve with control parametric principle that allows clearly regulate closing pressure by choicing of the geometric values regardless of the current load. Was proved that the shut-off element of control device control provides the required delay during switch on the friction clutch and a shaft of the second hydraulic drive to avoid their simultaneously recurrence
