文章摘要：水力空化是流體機(jī)械和液壓系統(tǒng)等旋轉(zhuǎn)機(jī)械中存在的一種流體力學(xué)現(xiàn)象,旋轉(zhuǎn)機(jī)械使用的機(jī)械密封憑借動(dòng)壓效應(yīng)在密封端面間形成厚度為微米級(jí)別的潤(rùn)滑膜,而微尺度液膜產(chǎn)生的空化現(xiàn)象對(duì)機(jī)械密封的性能有著重要的影響,端面液膜空化問題成了機(jī)械密封研究的熱點(diǎn)問題之一.為了更好地把握研究方向,從空化機(jī)理、試驗(yàn)研究和理論研究等3個(gè)方面分析了液膜潤(rùn)滑機(jī)械密封空化問題的研究現(xiàn)狀,綜合分析了宏觀空化、微觀空化、空化邊界條件和空化算法等問題的研究進(jìn)展.在對(duì)相關(guān)研究進(jìn)行總結(jié)的基礎(chǔ)上,對(duì)未來機(jī)械密封空化的研究方向進(jìn)行了展望：應(yīng)著重從空化理論模型、數(shù)值仿真技術(shù)、空化控制新技術(shù)和有效測(cè)量新技術(shù)等方面深入開展機(jī)械密封空化研究.

Abstr：Hydrodynamic cavitation is an extensive fluid mechanical phenomenon in rotating machines such as hydraulic machinery and hydraulic system. The micro-lubricating film is formed by dynamic pressure effect between fluid film lubricated mechanical face seals used in rotating machines. The cavitation of micro-scale fluid film between seal faces plays an important role in the performance of mechanical seals,which has become one of the hot issues of mechanical seal research. In order to grasp research directions in the future,the cavitation issue in liquid film lubricated mechanical seals was overviewd from the aspects of cavitation mechanism,experimental research and theoretical research.The progress of macroscopic cavitation,micro cavitation,cavitation boundary conditions and algorithms was analyzed synthetically. Subsequently,the future research directions of mechanical seals cavitation are proposed,which includes cavitation theoretical model,numerical simulation technology,new cavitation control technology and effective measurement technology.
