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.
Study the stress distribution of the mud pump body and optimize the structure of the pump body according to the analysis results to improve the power level of the mud pump.Firstly, the maximum force condition of the 1600HP mud pump body based on the 1800HP working condition is carried out, After preliminary analysis, it is found that the stress concentration of the front connecting plate and the main wall of the pump body does not meet the requirements of the material strength, and the structure of the pump body is optimally designed so that its strength meets the strength requirement of the 1800HP working condition, So as to improve the power level of the mud pump without increasing the total volume and total weight of the mud pump.The optimized 1600HP mud pump pump can meet different working conditions from 1600HP to 1800HP and can adapt to drilling only by replacing the corresponding motor Depth, and do not need to replace the corresponding lifting equipment, auxiliary pipe network and other equipment, effectively reducing the cost of land drilling platform and improve economic efficiency.
