通过分析苏联北部地区使用的苏联以及国外机器和装置的大量失灵和发生故障的原因,认为,在冬季造成设备失灵和发生故障的主要原因之一是由于橡胶或者聚合物局部或完全失去弹性,致使工作介质通过旋转轴上的橡胶唇形密封件大量泄漏造成的。为了选择适当的材料和采取保证设备的正常运转,在密封单元的设计和试验时就能充分可靠的预测密封件的工作性能,这也
By analyzing the large number of failures and malfunctions of the Soviet Union and other foreign machines and installations used in the northern Soviet Union, one of the major causes of equipment failure and failure during the winter is thought to be the partial or complete loss of elasticity of the rubber or polymer, The working medium is caused by a large amount of leakage of the rubber lip seals on the rotating shaft. In order to select the appropriate material and to ensure the normal operation of the equipment, it is possible to fully and reliably predict the performance of the seal during the design and testing of the seal unit.
