摘要: In a submerged scraper conveyor (10), an automatic voltage control system controls the speed of variable speed drive (32), in turn the speed of follower sprocket (22) and in turn the speed of drag chain (16) as a function of the torque on the headshaft (21). The tension on endless roller chain (36) is monitored by load cell (40) as indicative of the torque on the headshaft (21) and a standard process control signal is generated therefrom. The speed of variable speed drive (32) is varied as a function of the measured torque between a lower speed drive limit and an upper speed drive limit.
