机械密封泄漏量浅析

机械密封 王永拖 大连博格曼有限公司

  泄漏量是机械密封那个棋牌信誉好性能的重要指标。由于泄漏理论研究不充分,同时影响因素众多,目前工程界尚无广泛接受的泄漏量计算公式。该文希望能以工程计算的方式,提供一种油类泄漏量的变化趋势,供大家参考。

  目前理论界一般都采用德国E.迈尔(Mayer,E)提供的混合润滑状态下的泄漏量公式来进行机械密封泄漏量的定性研究。由于E.迈尔并未给出公式中流动系数C2的测定方法,所以真空技术网(http://tai3456.com/)认为不能通过该公式来得到泄漏量的精确解。国内密封书籍一般沿袭了E.迈尔的方法,目前尚未找到计算泄漏量的准确方法。
