摘要 |
<p>The invention relates to a dry-running piston rod sealing arrangement (1) for sealing a piston rod (2) mounted in a longitudinally displaceable manner. The sealing arrangement comprises at least one sealing ring (5) having a sealing surface (5a), an actuator (7), a sensor (8), and a chamber ring (3) containing the sealing ring (5). The actuator (7) comprises an active connection in relation to the sealing ring (5), such that the sealing surface (5a) can be radially displaced in relation to the piston rod (2). The actuator (7) can be controlled according to a measuring value detected by the sensor (8).</p> |
