Advantages of mechanical sealing materials:
1. The maintenance period is long, and the section can be automatically compensated after being worn. Under normal circumstances, regular maintenance is not required;
2. Good vibration resistance, not sensitive to the vibration, yaw of the rotating shaft and the deflection of the shaft to the sealing cavity;
3. The friction power consumption is small, and the friction power is only 10%~50% of the soft packing seal;
4. The shaft or bushing is substantially free of wear;
5. Wide range of applications, mechanical seals can be used for high temperature, low temperature, high pressure, vacuum, different rotation frequency, as well as a variety of corrosive media and seals containing abrasive media. However, mechanical seals also have the disadvantages of complicated structure, high requirements for processing and manufacturing, troubles in installation and replacement, requiring workers to have a certain level of skill, difficulty in handling accidental accidents, and high price.
6. Long service life, generally up to 1~2 years or longer in oil and water medium, generally working for more than half a year in chemical media;
7. The seal is reliable, the sealing state is stable during long-term operation, the leakage is small, and the leakage is about 1% of the soft packing seal;
8. There is no need to adjust during operation. Because the mechanical seal is close to the friction pair by spring force and fluid pressure, it will automatically keep in contact during operation. After assembly, it will not need to be tightened like ordinary soft filler to adjust.
