[摘要]:本次设计主要针对了振动筛的频率与振幅进行控制,利用偏心轴的惯性原理,对振动筛的振幅进行控制,通过电动机的转速来对振动筛的频率进行控制,设计中的为最佳工作状态,当电源中连上变频装置时,可以进行无极调速,振幅会随电动机的转速变化而变化。同时,在本次设计中,驱动电源采用了反接制动的接线方式,使振动筛在停车的时候,能快速通过共振区,减小了停车时的振幅。设计中还用到了概率筛分的原理,设计的是一种概率筛,相比与其他普通筛子,它的处理效率更快,更能适应现在的生活节奏。39795

[Abstract]:The design focused on the shaker frequency and amplitude control, the use of the principle of inertia eccentric shaft, for controlling the amplitude of the vibrating screen, to control the frequency of the vibrating screen by the motor speed, the design for the best work state, even when the power in the inverter device can be stepless speed, amplitude will change with the rotation speed of the motor change. Meanwhile, in this design, power supply with a reverse brake wiring, the vibration sieve when parking can quickly through the resonance region, reducing the amplitude of the parking time. Design also uses the principles of probability screening, the design is a probability screen, compared with other ordinary screen, its efficiency faster and more responsive to the current pace of life.
