1. Change the frequency string of load change of sludge drying equipment, which is used for torsional vibration to change the speed of the main shaft, but the speed of the main parameter of mechanical performance, one of the periodic changes of the load effect of the sludge dryer, its change is bound to be Affect the performance of the sludge dryer.
2, changing the natural frequency of the drive bearing system, mainly changing the shaft rotational inertia basin and stiffness. Among the practices and changes, etc., the moment of inertia of the limited size of the mechanical structure, the steel of the shaft has room for a greater increase or decrease. The elastic coupling is to change the stiffness of the shaft system and avoid the purpose of resonance.
