中文摘要:
      研究泥浆泵泵体的应力分布,并根据分析结果对泵体结构进行优化设计,以提高泥浆泵的功率等级.首先,对1600HP型泥浆泵泵体基于1800HP工况的最大受力条件进行有限元分析.经过初步分析后,发现泵体的前连接板和主墙板发生应力集中,不满足材料的强度要求.据此对泵体结构进行优化设计,使其强度满足1800HP工况的强度要求,从而达到在不增加泥浆泵总体积和总重量的基础上提高泥浆泵的功率等级.优化后的1600HP型泥浆泵泵体满足1600HP到1800HP不同的工况条件,只需更换相应电机就能够适应钻井深度的增加,而且不需要进行相应吊装设备、辅助管网等装备的更换,有效地降低了陆地钻井平台的成本,提高了经济效益.
英文摘要:
      To improve the overall capability of mud pump, the stress distributions of pump body was analyzed, and the pump case structure was optimized. The three-dimensional finite element method was adopted to analyses the stress and strain on 1600HP mud pump case, based on the 1800HP mud pump maximum load conditions. The preliminary analysis showed that the stress concentration locate in the front connecting plate and the side plate, which didn’t meet the material strength. The pump case was optimized to meet the required 1800HP condition according to the results of analysis. Without increasement of the total volume and total weight, the mud pump’s power grade was improved. The optimized mud pump can meet the conditions from 1600HP to 1800HP. Not only suit the change of drilling depth, lifting equipment and auxiliary pipe network equipment are not replaced, the cost of land rig is reduced greatly, the economic benefit is improved.
