双缸双作用隔膜泵动力端关键件的强度分析与评价

双缸双作用隔膜泵是煤化工领域水煤浆输送的关键设备，双缸双作用隔膜泵动力端主要由主动轴和皮带轮等关键部件所组成，这些关键部件能否满足强度要求不仅是泵设计人员应主要考虑的问题，也是隔膜泵在用户现场安全、稳定运行的关键因素。本文应用大型有限元分析软件ANSYS对动力端关键部件按实际工况进行强度分析并对分析结果进行评价，其结论对隔膜泵动力端相关部件的设计研发具有一定的理论指导意义。

Strength Analysis and Evaluation of Critical Parts in Double Cylinder Difunctional Diaphragm Pump Power End

Double cylinder difunctional diaphragm pump is the key equipment in coal water slurry conve- ying in coal chemical industry field. Double cylinder difunctional diaphragm pump power end consists of drive shaft, belt roller and other parts. These critical parts can meet the strength requirement or not should be considered for designers of pump, and also be taken as a determining factor for operating safely and steadily. In this paper, according to actual working condition, mechanical strength of critical parts in double cylinder difunetional diaphragm pump are analyzed and evaluated by finite element analysis soft- ware ANSYS. The analysis results provide some theoretical guidance for research and development of dia- phragm pump critical parts in Dower end.
