摘要
扫地车中的负压装置是决定扫地车工作效率的关键部件。负压装置下出风口的负压越小,吸尘效果越好。为了研究负压装置的结构参数与下出风口负压之间的关系,得到最佳的结构参数值,以主要结构参数(入风口宽度,内管高度、内管半径)为试验因素,使用均匀设计试验法设计试验方案,用FLUENT软件进行仿真试验,通过回归分析研究三个结构参数与下出风口处所产生的负压之间的关系,获得负压装置产生最小负压时的最优结构参数为入风口宽度为120 mm,内管高度为225 mm,内管半径为86 mm。经过按此参数制造的负压装置的扫地车试验验证,吸尘效率得到了提高,为扫地车负压装置的设计和优化提供了有益的参考。
The negative pressure device in the sweeper is the key component to determine the efficiency of the sweeper.The smaller is the negative pressure of the outlet under the negative pressure device,the better is the dust absorption effect.In order to study the relationship between the structural parameters of the negative pressure device and the negative pressure of the lower outlet and obtain the optimum structural parameter,the experiment with main structure parameters(air inlet width,tube height,radius of inner tube)as the test factors,adopts uniform design test method to design the test scheme,the simulation test is carried out with FLUENT software,and the relationship between the three structural parameters and the negative pressure produced at the lower outlet is studied by regression analysis.The experimental results show that the optimum structure parameter of the negative pressure device is obtained when air inlet width is 120 mm,inner tube height is 225 mm and inner tube radius is 86 mm.Through the test of the sweeper of the negative pressure device manufactured according to these parameters,the dust absorption efficiency is improved,which provides a useful reference for the design and optimization of the negative pressure device of the sweeper.
