①The sealing is reliable. In the long-term operation, the sealing state is very stable. The leakage is very small. According to rough statistics, the leakage is generally only 1/ of the packing seal. 100;

②Long service life is generally up to 1-2 years or more in oil and water media, and it can be used reasonably in coal preparation media, usually more than one year.

③The friction power consumption is small, and the friction power of the mechanical seal is only 10%-50% of the packing seal;

④The shaft or sleeve is basically free from wear;

⑤ The maintenance cycle is long, and the end face can be automatically compensated after wear. Under normal circumstances, frequent maintenance is not required;

⑥ Good vibration resistance, insensitive to the vibration and deflection of the rotating shaft and the deflection of the shaft to the sealed cavity;

⑦Scope of application Mechanical seals can be used for sealing at low temperature, high temperature, vacuum, high pressure, different speeds, as well as various corrosive media and media containing abrasive particles.　　207.html,
