由于机械密封比填料密封具有密封性能好、摩擦阻力小、对磨面磨损缓慢、安装维修简便等优点,所以应用日趋广泛。尽管机械密封装置的种类和形式很多,但密封原理基本一致,都是利用带有缓冲机构(图1中的3、4、9、10),与轴大体垂直并作相对运动的两个密封端面(图1中的1.2)进行密封的。对整个机械密封装置来说,影响密封性能的关键零件是动环和静环。所以对动环和静环的材质选择,结构设计以及加工等都有严格要求。但从机械密封装置的制造和维修角度出发,关键工序是动、静环的研磨。本文仅就影响研磨质量的各种因
As the mechanical seal than the packing seal has a good sealing performance, friction resistance, abrasive wear on the slow, easy installation and maintenance, so the application is becoming more widespread. Although the type and form of the mechanical seal are many, the sealing principles are basically the same, both of which are based on the use of two sealing end faces (3, 4, 9, 10 in Fig. 1) (1.2 in Figure 1). For the entire mechanical seal, the key components that affect the sealing performance are moving and stationary rings. Therefore, the moving ring and static ring material selection, structural design and processing, and so have strict requirements. However, the mechanical seal from the manufacturing and maintenance point of view, the key process is dynamic and static grinding ring. This article only affects the quality of grinding various causes
