Design and Research of Large-Inclination Screw Conveyor Angle Changing Test Equipment

Abstract:

This paper mainly introduces the design of a test equipment for large-inclination screw conveyor, especially focuses on the structure, function and the hydraulic control system. The test equipment can work well under the condition of the variable speed and angle, and even under different structural parameters and different conveyed materials. PLC programmable controller with the hydraulic control system can control the electro-hydraulic proportional valve automatically and eliminate the problems such as dead zone and hysterics of electro-hydraulic proportional valve itself, which helps us to develop a set of the electro-hydraulic control system, and also can be used as a platform for big dip screw conveyor experimental research.
