摘　　要：为了研究摩擦热、介质压力对剖分式机械密封变形的影响,对剖分式机械密封进行热力耦合数值分析。结果表明:在温度场中密封环外径侧温度较低,剖分动环端面最高温度出现在与剖分静环相接触的密封端面处,剖分静环端面最高温度出现在密封端面内径处;在热、力耦合作用下密封端面由外径向内径的变形形成收敛状间隙;随着介质压力增大,密封环的轴向变形增大,密封环分型面的径向变形减小;介质压力的变化导致密封环端面间产生的摩擦热不同,从而引起密封环变形的差异。In order to study the effects of frictional heat and medium pressure on the deformation of split mechanical seals,this paper carries out thermal-mechanical coupling numerical analysis of split mechanical seals.The results show that,in the temperature field,the temperature on the outer diameter side of the seal ring is lower,the highest temperature of the end face of the split dynamic ring appears at the seal end face that is in contact with the split static ring,and the highest temperature of the end face of the split static ring appears at the inner diameter of the seal end face.Under the action of heat and force coupling,the sealing end face forms a convergent gap from the deformation of the outer diameter to the inner diameter.As the medium pressure increases,the axial deformation of the sealing ring increases,and the radial deformation of the sealing ring parting surface decreases.The change of medium pressure leads to the difference of frictional heat generated between the end faces of the sealing ring,which causes the difference of the deformation of the sealing ring.
