摘要： A seal for preventing leakage of fluid from between a first member and a second member has a seal body and a seal wear indicator. The second member is capable of moving toward and away from the first member. The seal body is adapted for engaged contact with the first and second members so as to prevent leakage of fluid as long as the seal has not worn beyond a specified depth. A seal wear indicator is positioned within the seal body at approximately the specified depth, such that when the seal has worn to the specified depth, a change in the optical conductor is detected, indicating that the seal needs replacement.

摘要： Pumps and valves with movable parts, such as a plunger, typically have seals around the part. The seals may isolate one chamber from another to prevent leakage across the seals. The pressure in one chamber may be different from the pressure in another adjacent chamber, thereby creating a pressure differential across the seal. When the seal is working properly, the pressures in the adjacent chambers remain constant approximately. However, when a seal leaks, pressure will leak across the seal. As such, the chamber with the lower pressure will show an increase in pressure due to seal leakage. Thus, monitoring pressure changes in the chamber with low pressure, or pressure differentials between chambers, serves as an indicator for leakage across the seal and impending seal failure.
摘要翻译：具有可移动部件（例如柱塞）的泵和阀通常在部件周围具有密封。密封件可以将一个腔室与另一个腔室隔离，以防止密封件上的泄漏。一个室中的压力可以与另一个室中的压力不同，从而在密封件两端产生压力差。当密封件正常工作时，相邻腔室中的压力保持不变。然而，当密封件泄漏时，压力会泄漏到密封件上。因此，具有较低压力的室将由于密封泄漏而显示出压力增加。因此，以低压或室之间的压力差监测室内的压力变化，用作渗透密封件和即将出现的密封件故障的指示器。

摘要： One method empirically determines a stiffness value for each of two or more different subsets of the bristles of a brush seal, then calculates a variation in stiffness, and then identifies the brush seal as defective if the calculated variation in stiffness exceeds a predetermined stiffness variation criteria. One apparatus includes a load transducer having a contact head sized to contact less than twenty percent of the bristles, a displacement transducer which measures the displacement of the free ends of the contacted bristles, and a clamp for securing the brush seal and presenting the bristles for contact.

摘要： When a seal is inserted onto a shaft, load applied to a chuck is detected by a load cell, and based on the detected load, the turnover of a lip is judged. More specifically, an operation of inserting and pulling out the seal is performed several times on the shaft. Pull-out force is detected at the time of the last pull-out operation and insertion force is detected at the time of the last insertion operation. If the detected value is greater than a predetermined value, it is judged that the lip has been turned over. Also, a ratio between the aforementioned pull-out force and insertion force is computed. If the value of the computed ratio is less than a predetermined value, it is judged that the lip has been turned over.
摘要翻译：当将密封件插入到轴上时，通过称重传感器检测施加在卡盘上的负载，并且基于检测到的负载，判断唇缘的周转。更具体地说，在轴上进行几次插入和拉出密封的操作。在最后的拉出操作时检测出拉出力，并且在最后的插入操作时检测到插入力。如果检测值大于预定值，则判断唇已经翻转。而且，计算上述拉出力和插入力之间的比率。如果计算出的比率的值小于预定值，则判断唇缘已经翻转。

摘要： A seal for preventing leakage of fluid from between a first member and a second member, the second member is capable of moving toward and away from the first member, the seal is adapted for engaged contact with the first member and the second member so as to prevent leakage of fluid between the first member and the seal and between the second member and the seal, the seal being softer than the second member such that friction between the seal and the second member wears the seal faster than the second member, the seal being adapted to retain a tight seal against the second member as long as the seal has not worn beyond a specified depth; and a conductor for placement about the second member, the conductor being attached to the seal at the specified depth so as to contact the second member when the seal has worn to the specified depth, such that the existence of electrical continuity between the conductor and the second member indicates that the seal requires replacement, the conductor is positionally associated to the seal such that wear of the seal corresponds with movement of the conductor toward the second member; and the electrical continuity indicates whether the seal requires replacement.

摘要： A method for monitoring the condition of a piston rod sealing system of a piston compressor, the system having at least two annular chambers arranged one behind the other in a longitudinal direction and each having a sealing element arranged therein. A piston rod running through the sealing elements and the annular chambers is moved back and forth in the longitudinal direction, sealed by the sealing elements. The system has an inlet side and an outlet side, between which a difference in pressure occurs, and said difference in pressure has static and dynamic pressure component. When there is leakage gas in the annular chambers, at least the dynamic pressure component of the leakage gas is measured in the piston rod sealing system. A change in the condition of at least one of the sealing elements is determined from a change in the dynamic pressure component as a function of time.
