【摘要】：機械密封實驗裝置主要用于對機械密封以及其他種類的旋轉(zhuǎn)式動密封進行性能實驗、密封產(chǎn)品考核實驗和模擬現(xiàn)場工況的密封性能實驗。本文是針對機械密封實驗裝置研發(fā)項目進行的研究。研發(fā)項目要求具有較高的實驗轉(zhuǎn)速,結構簡單,能夠進行新型非接觸式機械密封與普通機械密封的液體密封性能實驗。 本文應用3D設計軟件Solidworks進行實驗裝置設計,比較詳細地進行了各個組件的設計和選型,得到了符合研發(fā)項目要求的設計結果。除了整機的研發(fā),還對一些重要部件進行了研究。傳動軸作為一個重要零件,影響著實驗裝置的測試精度。對傳動軸的設計采用了兩種方法:首先是公式計算法,根據(jù)強度理論計算出了最小軸徑;然后運用軟件Simulation進行有限元分析,找到了在實驗過程中受力狀態(tài)下的變形參數(shù),進行了優(yōu)化設計和驗證。 針對非接觸式機械密封的特點,進行了實驗設計。與普通機械密封不同,非接觸式機械密封的端面參數(shù)決定了密封性能。因此,在實驗設計之前,進行了非接觸式機械密封參數(shù)計算,并采用Flow Simulation進行了兩種非接觸式液膜機械密封的端面流場分析。詳細介紹了分析過程,找到了端面流場的壓力、溫度等參數(shù)的分布規(guī)律,對雙列交叉動壓槽非接觸式液膜機械密封的優(yōu)點進行了驗證。根據(jù)分析結果,設計了對比實驗。
[Abstract]:The mechanical seal experimental device is mainly used to test the performance of mechanical seal and other kinds of rotary dynamic seal. This paper is aimed at the research and development project of mechanical seal experimental device. The research and development project requires high experimental speed and simple structure. It can be used to test the liquid seal performance of new non-contact mechanical seal and general mechanical seal. In this paper, the 3D design software Solidworks is used to design the experimental device. The design and selection of each component are carried out in detail, and the design results that meet the requirements of the R & D project are obtained. Some important parts are also studied. As an important part, the transmission shaft affects the testing accuracy of the experimental device. Two methods are used for the design of the drive shaft: first, the formula calculation method is used. The minimum axis diameter is calculated according to the strength theory, and then the finite element analysis is carried out by using the software Simulation, and the deformation parameters under the stress state during the experiment are found, and the optimum design and verification are carried out. According to the characteristics of non-contact mechanical seal, the experimental design is carried out. Different from ordinary mechanical seal, the end surface parameters of non-contact mechanical seal determine the sealing performance. Therefore, before the experimental design, The parameters of non-contact mechanical seal are calculated, and the flow field on the end surface of two kinds of non-contact hydraulic film mechanical seal is analyzed by Flow Simulation. The analysis process is introduced in detail, and the distribution law of the pressure and temperature of the end surface flow field is found. The advantages of non-contact hydraulic film mechanical seal with double-row cross dynamic pressure groove are verified. According to the analysis results, a comparative experiment is designed.
