A hydraulic drive system and method for driving a belt conveyor

摘要

The present invention relates to a hydraulic drive system for a belt conveyor (12) with a in a hydraulic primary circuit (26), arranged in the form of a motor driven primary pump (28) for supplying hydraulic fluid, a via the primary circuit (26), which is supplied with hydraulic fluid hydraulic motor (30) for driving of the belt conveyor (12) and a the flow of hydraulic fluid in the primary circuit (26) which influences the control device for controlling the speed of the belt conveyor (12). According to the invention, it is proposed that the primary pump (28) as a variable displacement pump a pump control (32) for regulating the hydraulic fluid flow is conveyed, and in that the control device by means of an auxiliary pump (54) operated hydraulic control circuit (24) for actuation of the pump regulator (32) with an adjustable control pressure comprises.
