自吸网式过滤器过滤时间与自清洗时间变化规律分析（Analysis of Filtering Time and Sewage Time for Automatic Suction Screen Filter）
微灌 过滤器 过滤时间
2010/12/28
微灌用过滤器是保证整个微灌系统正常运行的核心过滤设备，开发具有自清洗功能的过滤设备则是研究的重点。在对自吸网式过滤器进行水力性能试验的基础上，分析了自吸网式过滤器过滤时间的变化规律，表明过滤时间的变化并非呈线性规律；分析了自清洗时间的影响因素，指出自清洗时间并不是恒定不变的，而是在其他参数固定时与进水含沙量S0呈反比关系。
风筛式清选装置筛面气流场试验（Experiment on the Flow Field of the Air-and-screen Cleaning Device）
风筛 清选装置 气流场 试验
2009/12/28
在DFQX-3型物料清选仿真试验台上，通过空间布点测量了筛面不同位置的气流速度。根据测量值得出筛面上流速小于或等于4.81 m/s，属低速气流。利用Matlab绘制了筛面不同位置的横断面、纵断面、水平面的等速线和速度变化曲线，分析了风筛式清选装置的筛面气流场速度分布规律。试验表明，筛面两侧的流速对称分布，前后两端流速较接近，中间流速变化复杂。

风筛式清选装置非均布气流清选原理与试验（Theory and Experiment on Non-uniform Airflow Cleaning of Air-screen Cleaning Unit）
联合收获机 清选 非均布气流
2009/5/22
脱出物从横置的轴流式脱粒装置下落到纵置的清选筛上时，在筛面入口段堆积成堆影响清选。提出了非均布气流清选原理，设计了圆锥形离心风扇以产生非均匀气流。理论分析和试验验证表明：由圆锥形离心风扇大、小端的直径差形成的非均布气流产生了风压差，使振动筛前部出现了较大的横向风速(最高处2.6m/s)，将下落中的脱出物向另一端吹送，使脱出物在振动筛面的初始分布明显改观，从而改善了横置轴流式全喂入联合收获机的清选性...
