摘要
螺旋流恒压泵动态机械密封寿命低的问题一直困扰着制造企业和用户。针对螺旋流恒压泵密封系统寿命低的问题,通过对螺旋流恒压泵内部流场原理和机械密封结构的分析研究,首先构建了恒压泵内部流场数学模型,其次通过对内部流场压力、扬程和效率等关键技术参数以及机械密封结构的研究,设计了一种斜孔压差导流冷却循环结构。通过实验,对斜孔压差导流冷却循环螺旋流恒压泵的关键技术参数进行了优化,同时也证明了该技术的先进性、可行性和实用性,为该技术的实际应用奠定了理论和实验基础。
The low dynamic mechanical seal life of the spiral constant pressure pump has been a troubling problem for the manufacturing companies and users.Through an analysis of the internal flow field mechanism of the spiral constant pressure pump and its mechanical seal structure,the mathematic model of the internal flow field was established firstly,and then some key technical parameters,such as the internal flow field pressure,the pumping head,the efficiencies,and the mechanical seal structure,were presented and discussed thoroughly.Finally,the cooling cycle structure of the diagonal hole differential pressure diversion was designed.Based on the experimental proof,the key technical parameters of the spiral constant pressure pump were optimized.Meanwhile,the advancement,the practicability and feasibility of the technologies were also proved by the experiment,which would lay the theoretical and experimental foundation of the technology applications.
