Design and Test Research of Allotter in Centralized Pneumatic Seeding System 集中式排种系统中分配器的设计及试验研究
According to the agricultural material characteristics and the design request of the allotter, the allotter was designed and manufactured, and its pressure loss was calculated. 根据种子的物料学特性和分配器的设计要求,设计制造了I型分配器,并计算其压强损失。
A Research on the Design of Pulsating Allotter of Stepmotor with ISP Devices 用ISP器件实现步进电机脉冲分配器的设计研究
When designing the step motor drive circuit of 5 phase 10 pat, 89C2051 is adopted as the Loop allotter. The VMOS is adopted in power elements. It is designed as chopper-type constant current circuit. 设计五相十拍步进电动机驱动电路时选择了89C2051作为环形分配器,而功率器件选用电压型的VMOS管。
Practical Pulse Allotter of Stepping Motor 实用步进电机脉冲分配器
The test proved that, the seeding quantity variance coefficient of the allotter with the shunting cone is lower by 2% than that of the allotter without the shunting cone under the same work conditions. 试验结果表明:如果其它条件不变,分配器安装分流圆锥要比不安装分流圆锥时的变异系数低2%左右;
