An Example of plete Seal
Simply put, a mechanical seal is:简单的说,机械密封就是:
1. A wearable, stationary, primary sealing element
一个耐磨,静止的密封件
2. A wearable, rotating, primary sealing element
一个耐磨,旋转的密封件
3. A secondary sealing element
二次密封
4. A mechanical loading device to press primary sealing elements 1 and 2 against one another, and
使件1和件2相互贴合的机械装置
