Abstract : three kinds of injection sleeves construction , materials , surface treatment and application ranges of floating end face seal ring by die casting are expounded 文摘:叙述浮动端面密封环压力铸造的三种压射套结构、材料和表面处理工艺及其应用范围。
Mechanical seal : use of wb2 and st non - water - cooled adjustable end face sealing technology , composed of silicon carbide , high purity alumina ceramic , packing ptfe and graphite etc 机械密封：采用wb2型、 st型不用冷却水可调式端面密封技术，由碳化硅，高纯度氧化铝陶瓷、填充四氟，石墨等材料制成。
The dishing ring seals belong the end face sealing parts , and act as sealing by some axial compression . because of different distribution of internal pressure and temperature , the friction inside the end - face is also different at all area 碟形密封圈属于端面密封元件，依靠一定的轴向压缩量进行密封，由于端面内压力分布、温度分布不均，端面内的摩擦状况也不是处处相同。
6 , turn son to carry noodles to seal completely an adoption adjustable seal completely device , from compound material and metal alloy inside of circle wreath get in touch with , donot need lubricant lubrication , sealing completely function good , structure simple , adjust to maintain convenience . turned bearings in order to roll over bearings , use the function good life span to grow 6转子端面密封采用可调密封装置，由复合材料与合金圈内环接触，不需要润滑油润滑，密封性能良好结构简单调整维修方便。转了轴承为滚动轴承，使用性能良好寿命长。
" sir , " said the notary , whose interest had been greatly excited , and who had resolved on publishing far and wide the account of this extraordinary and picturesque scene , " what appeared so impossible to me an hour ago , has now become quite easy and practicable , and this may be a perfectly valid will , provided it be read in the presence of seven witnesses , approved by the testator , and sealed by the notary in the presence of the witnesses “阁下， ”公证人说道，这件事已引起了他极大的兴趣，他已决定要极大地扩展这个奇特的场面， “我在一小时已前还以为极不可能的事，现在已是很容易实现的。这份遗嘱，只要在七个证人面前宣读过以后，经遗言人的确认，再由公证人当着证人的面密封起来，就可以完全奏效了。
