The machine has forward and reverse rotation speed Promise. 本机拥有正向、反向无极调速旋转。
Pumps can be stopped without unusual reverse rotation; 停运泵正常不反转。
The reverse rotation will result in destruction of the dry gas seal and other components. 压缩机反转将对干气密封及其他零部件造成破坏,严重影响了乙烯装置的平稳、高效运行。
This paper mainly studies on the following works based on four-wheel vehicle. ( 1 ) Establish of kinematics and dynamics models of differential steering system with front and rear wheels reverse rotation. 本文以四轮驱动小车为研究对象,主要进行了以下几方面的研究:(1)建立了前后轮反向转动差速转向模型的运动学和动力学模型。
In the numerical case, the critical speed of the dual rotor structure with normal and reverse rotation calculated by the finite element method dynamics model and the transfer matrix method model was agreed. 结合数值案例,应用基于有限单元法的动力学模型和传递矩阵法模型计算双转子结构正反向旋转(RR)下的临界转速,两种方法得到的结果一致。
