疏浚泥泵前衬板材料的耐磨蚀数值模拟及试验研究
|
摘要
大型泥泵前衬板磨蚀严重,为提高泥泵前衬板的耐磨蚀性能,探究适宜的耐磨蚀材料,采用Fluent软件对泥泵内部流场进行数值模拟,并针对多种材料进行不同颗粒粒径下的磨蚀试验。研究结果表明:随颗粒粒径的增大,泥泵内圈前衬板磨蚀率减小,外圈肩胛环磨蚀率增大。在不同颗粒粒径磨蚀工况下,碳化钨磨蚀量最小,硬度72度的聚氨酯弹性体材料次之,两者抗磨蚀性能均优于目前广泛使用的高铬钢。
In order to improve the abrasion performance of the front liner of mud pump and explore suitable wear resistant materials,Fluent software was used to carry out numerical simulation of the internal flow field of the mud pump,and the abrasion tests with under different particle sizes were conducted to evaluate the wear resistance of various materials. Results showed that with the increase of particle size,the abrasion rate of the inner liner of the mud pump reduced,while the abrasion rate of the outer ring shoulder ring increased. Under the different particle size abrading conditions,the tungsten carbide had the minimum abrasion amount,and the polyurethane elastomer with hardness of 72 was the second. Both of them possessed better abrasion resistance than the high chromium steel,which was used currently widely.
