摘要
泵送过程中混凝土骨料易聚集于泵管中而堵塞泵管。针对这一问题,设计了一种含有螺旋叶片的防堵机构。采用CATIA建立其三维模型,并利用FLUENT软件对泵管中混凝土流场进行数值模拟分析。分析表明,设计的防堵机构改善了泵管中混凝土的流动特性,可有效防止混凝土堵塞泵管。
Concrete aggregates gatheres ea sily in pump pipe and then blocked pump pipe during the process of pumping. To solve this problem, an ant i-blocking mechanism with spiral blade is designed. 3D solid model of this mechanism is built using CATIA. Numerical simulation of the fluid field of concrete is carried out using software of FLUENT. Result shows that liquidity of concrete is improved after adding ant i-blocking mechanism. The ant i-blocking mechanism will prevent concrete from blocking pump pipe.
