密封元件密封面接触应力的测量

Measurement of Contact Stress on the Sealing Surface of Sealing Elements

介绍了西北工业大学研制的密封面接触应力的电测装置。该装置能在模拟密封元件工作环境(工作介质及介质压力)的情况下,直接准确地测量出密封元件密封面的接触应力。使用结果表明该装置使用方便、安全可靠、测量精度高(传感器精度优于0.5％F.S)。比较好地解决了封隔件密封面接触应力测量难题。

In this paper, an electric device is proposed to measure contact stress on the sealing surface of sealing elements. With this device, the contact stress can be straightly and precisely measured at simulating working environments of sealing elements. It is shown from practice, that this device is convenient and safe in use. The accuracy of the contact stress sensor is better than 0.5％ F. S.
