摘要
基于现有泥浆泵活塞在使用中因摩擦生热而引起的胶皮高温失效,并导致活塞寿命降低的问题,研究分析了活塞承受工作压力和散热性能之间的数学关系。结合遗传算法建立了新型活塞结构的优化模型,采用实数编码方式对新型活塞的工作压力和散热性能进行优化,得出综合性能最佳的的优化结果,优化后的活塞结构在适当降低可承受工作压力的情况下,可以有效的提高活塞的散热效率。研究结果对新型活塞结构的设计制作以及提高活塞寿命、降低钻井成本、有着重要指导意义。
Based on the existing mud pump piston life decrease phenomenon caused by piston rubbers failed in use because of the high temperature and friction heat,the mathematical relationship between the piston working pressure and the heat dissipation performance were analyzed in this research.The new mud pump piston＇s structure mathematical model of optimization is established on the basis of genetic algorithm. The working pressure and heat dispersion performance of the new mud pump piston is optimized by using the real number coding method and obtain the best comprehensive properties of optimization results,in the case of appropriately reducing the external workpressure,the optimized structure ofpiston can effectively improve the heat dissipation efficiency of piston.The results of the study for new type piston structure design and improve the life of the piston,reducingdrilling cost,has important guiding significance.
