具有最小泄漏的机械密封装置
摘要：
本发明涉及机械密封装置，其包括：具有旋转滑环(3)和固定滑环(2)的机械密封件，其中两个滑环中的一个滑环具有第一滑动面(30)，两个滑环中的另一个滑环具有第二滑动面(20)，第二滑动面(20)具有周向封闭的密封边缘(22)，密封边缘(22)从第二滑动面的基部区域(21)在朝向第一滑动面(30)的方向上突出高度(H)，密封边缘(22)具有在10μm至500μm的范围的宽度(B)，至少一个预应力元件(4)对滑环施加预应力使滑环彼此抵靠，第二滑动面(20)和第二滑动面(20)处的密封边缘(22)具有金刚石的涂层，或者第二滑动面(20)和第二滑动面(20)处的密封边缘(22)具有立方氮化硼的涂层，并且在第一滑动面(30)和第二滑动面(20)之间存在OH-离子供体(10)和/或H+离子供体(10)。
摘要（英）：

The invention relates to a mechanical seal assembly comprising a mechanical seal with a rotating slide ring (3) and a stationary slide ring (2), wherein one of the two slide rings has a first slide surface (30); the other of the two slide rings has a second slide surface (20) with a circumferentially closed sealing blade (22) which protrudes from a bottom region (21) of the second slide surface inthe direction of the first slide surface (30) by a height (H); the sealing blade (22) has a width (B) in a range of between 10 and 500 [mu]m; at least one pre-tensioning element (4) braces the sliderings against each other; the second slide surface (20) and the sealing blade (22) on the second slide surface (20) have a diamond coating, or the second slide surface (20) and the sealing blade (22)on the second slide surface (20) have a coating of cubic boron nitride; an OH- ion donor (10) and/or an H+ ion donor (10) is present between the first slide surface (30) and the second slide surface (20).
