Study of Vibration Decreasing and Energy Saving of Rotary Grading Screen

摘要:

针对回转分级筛振动大、能量浪费等问题，对其系统能量进行了分析，系统总能量在工作过程中呈周期性波动，造成能量浪费和冲击振动，提出了一种基于系统总能量恒定的节能减振方法，在系统中设置适当的弹性元件，将工作过程中的耗散能量转化为弹性势能，再将弹性势能转化为驱动能量，来保持系统总能量恒定。试验表明，该方法节能21.71%，减振30.89%，具有较好的节能减振效果。

Abstract:

In order to solve the high vibration and energy dissipation of rotary grading screen, the system energy of the rotary grading screen in operation process was analyzed. The total energy of system in operation process was periodic, and it caused the high vibration and energy dissipation of the rotary grading screen. A method based on the constant total energy of system was proposed and the elastic component was disposed. It transformed dissipated energy into elastic potential energy and transformed elastic potential energy into driving energy so as to remain the constant total energy of system. The experimental results showed that the proposed method saved energy consumption by 21.71% and decreased vibration by 30.89%. It had better effect in energy saving and vibration decreasing.
