联邦德国CARL FREU DENB ERG SIMRIT公司是世界上最大的密封件制造公司之一。它和日本最大的密封公司NOK以及美国的国际密封公司属同一集团,所以实力雄厚,技术上也处于领先地位。下面就SIMRIT公司生产的一些新型密封件的结构、特点和性能作一概要的介绍。一、液压活塞杆密封在液压缸中,唇部带回切倒角的皮碗得到了广泛的应用。当压力低于16MPa时,可以使用纯橡胶皮碗密封。当压力在16～25MPa之间时,必须使用挡圈或者使用织物增强橡胶皮碗。当压力更高时,除了使用挡圈之外,皮碗的唇部必须用织物增强。 Federal Republic of Germany CARL FREU DENB ERG SIMRIT is one of the largest seals manufacturers in the world. It is the same as Japan’s largest sealed company NOK and the United States, the international seal company is the same group, so the strength, is also technically in the lead. Here’s a brief overview of the structure, features and performance of some of the new seals manufactured by SIMRIT. First, the hydraulic piston rod seal in the hydraulic cylinder, the lip with back chamfering cup has been widely used. When the pressure is lower than 16MPa, you can use pure rubber cup seal. When the pressure is between 16 ~ 25MPa, you must use the ring or fabric reinforced rubber cup. When pressure is higher, the lip of the cup must be reinforced with fabric, except for the retaining ring.
