中文摘要
可控液压往复密封(CHRS)因可主动补偿密封间隙而广泛应用于高密封可靠性要求场合,有望突破现有深海传统密封因间隙补偿能力缺乏所致密封可靠性不足、寿命过短的技术瓶颈,但其间隙补偿调控机制尚不清楚。本项目拟开展深海极端服役环境下CHRS密封界面成膜机理及主动调控策略研究,主要包括三个方面,其一是基于深海环境和调控行为特点,建立深海CHRS热力耦合模型,研究深海CHRS热-粘弹性力学行为及密封/沟槽结构协同优化;其二是耦合密封件热力变形,建立深海CHRS“热流固”多场耦合瞬态热弹流模型,研究CHRS界面流体运动行为及密封性能演变规律;其三是开展外部调控压力对密封性能影响机制及规律研究,构建“外部调控压力-界面膜厚-泄漏率”定量调控关系,提出深海CHRS控漏减摩动态调控策略。本研究有望形成高性能、高可靠性深海CHRS结构设计准则和行为调控方法,以满足我国深海装备深化发展中关键密封技术的迫切需求。
英文摘要
Controllable hydraulic reciprocating seal (CHRS) has been widely used in occasions with high sealing reliability requirements for its ability of compensating sealing clearance actively, and hopefully breaks through the technical bottleneck of existing traditional hydraulic reciprocating seal which shows insufficient reliability and short service life under deep-sea environment caused by lacking of clearance compensation ability, but its control mechanism of clearance compensation is still unclear. In the present project, study will be carried out on fluid film-forming mechanism between sealing interface and active control strategy of CHRS under the deep-sea extreme service environment. The research will be conducted mainly in three aspects. Firstly, to develop thermal mechanical coupling model of CHRS under deep-sea environment based on characteristics of deep-sea environment and control behavior, so as to analyze thermal-viscoelastic behavior of CHRS under deep-sea environment and collaborative optimization of seal and groove structures. Secondly, to establish thermal-fluid-solid multi-field coupled transient thermal elastohydrodynamic model by coupling thermal deformation of seal ring, so as to investigate fluid movement behavior in micron-clearance and sealing performance evolution of CHRS under deep-sea environment. Finally, to carry out study on influence mechanism and influence rule of external control pressure on sealing performance, so as to establish quantitative control relationship among external control pressure, interfacial film thickness and leakage rate, and put forward dynamic control strategy of leakage control and friction reduction of CHRS under deep-sea environment. Through above studies, it is expected to form structural design criteria and behavior control methods of CHRS under deep-sea environment with properties of high-performance and high-reliability, which can meet the urgent needs of key sealing technologies in the deepening development of deep-sea equipment of our country.
