2XZ-15旋片式真空泵设计 摘 要 旋片泵是最基本的一种真空获得设备，它既可以单独用来获取低中真空，也可以作为其它中高真空泵的前级泵来使用。近些年来，直联式旋片泵随着电子、半导体、制药以及食品包装行业的发展而得到了迅速发展。但是国内的直联旋片泵在性能上满足不了行业需求，而国内进口泵价格又太高，在这种情况下，有必要研发新的直联式旋片泵，在性能上追赶国外进口泵，同时在价格上让国内用户容易接受。 在此次毕业设计工作中，首先分析了当前的真空获得设备的市场情况以及国内外旋片泵在性能、价格上的差异，肯定了新型直联旋片泵研发的必要性。随后，详细分析了国内旋片泵在性能上存在的问题，主要是极限真空、抽气效率、噪声、喷油及漏油这几个指标。针对问题，结合现有技术水平，给出解决方案和设计目标。根据解决方案，提出了结构上几个关键的改进和创新，即新型的排气过滤器和进气口的捕集器、改进的挡油板和排气口结构，以及外形的变动设计。 本工作所设计的双级直联双旋片式真空泵，是在分析、吸收众多国外著名公司及国内公司的结构及技术，再进行创新而开发出来的一种集过滤与捕集功能为一体的整体式旋片真空泵。它具有节能、无需水冷、可直排大气等优点：同时体积小、重量轻、操作简单、维修方便；广泛应用于真空包装、薄膜制备与吸塑成型等领域。 关键词：旋片泵，直联，过滤器，捕集器 2XZ-15 rotary vane vacuum pump design Abstract The rotary vane pump is the most basic kind of vacuum equipment, it can be individually used to obtain the low and medium vacuum, can be used as other high vacuum pump before the pump. In recent years, direct coupled rotary vane pump with the electronics, semiconductor, pharmaceutical and food packaging industry has been rapid development. Direct rotary vane pump in the domestic performance failed to meet the industry demand, the domestic prices of imported pumps are too high, in this case, there is a need to develop new Direct rotary vane pump performance to catch up with the imported pumps while the price for domestic users to easily accept. In the graduate design work, the first analysis of the vacuum equipment in the current market conditions, as well as domestic and foreign rotary vane pump, the difference in performance, price, and affirmed the necessity of the new direct rotary vane pump is developed. Subsequently, a detailed analysis of the problems of domestic rotary vane pump performance, ultimate vacuum and pumping efficiency, noise, fuel injection and oil spill a few indicators. The problem with the existing level of technology, given solutions and design goals. The solution structure on a few key improvements and innovations, new exhaust filters and air intakes of the trap, improved oil baffle plate and the structure of the exhaust
