摘要:
为了研究深海复杂恶劣工况对深海涉水装备动力装置的影响,以深海推进器用接触式机械密封为研究对象,建立其二维轴对称有限元模型,探究了交变工况对密封端面温升的影响;在自行搭建的试验台上进行了机械密封拟实工况试验,监测了端面温升情况,测量并分析了端面形貌及磨损特性.结果表明:交变工况对密封环温度场有显著影响,且端面温升呈现明显的交变瞬态特性;交变工况试验后动环端面粗糙度显著增大,工况瞬变使得端面接触状态不稳定,端面发生磨粒磨损,出现明显的凹坑和深浅不一且密集分布的犁沟;交变转速较交变介质压力对端面温升及磨损的影响程度更大.数值模拟与试验结果趋势吻合良好,为深海推进器机械密封结构设计提供必要的理论指导及试验依据.
