浮动油封结构简单、密封可靠、使用寿命长、平时无需注油。近年来被广泛应用在履带式推土机、挖掘机等施工机械上。浮动油封的制造质量、安装要求和维护保养对其使用性能和寿命影响甚大。因此,浮动油封的试验成了不可缺少的环节。本文介绍的浮动油封试验机,具有性能好、效率高、用途广、造价低等特点。 The floating oil seal has a simple structure, reliable sealing, long service life, and no oiling at ordinary times. In recent years, it has been widely used in construction machines such as crawler bulldozers and excavators. The manufacturing quality, installation requirements and maintenance of floating seals have a great influence on their performance and life. Therefore, the test of floating seals has become an indispensable link. The floating oil seal tester introduced in this paper has the characteristics of good performance, high efficiency, wide use, and low cost.
