Advantages Of Water Pump Mechanical Seal

1. The structure is reliable and can limit the leakage to a small range. As long as the surface roughness and flatness of the main sealing surface can meet the requirements, as long as the material has good wear resistance, the mechanical seal can achieve very small leakage, and even the leakage is invisible to the naked eye.

2. Long lifespan. In mechanical seals, the main wear part is the sealing friction pair end face. Since the wear of the seal end face is not significant under normal operating conditions, it can usually be used continuously for 1 to 2 years, and in special cases it can also be used for 5 to 10 years.

3. No adjustment required during operation. Since the mechanical seal relies on spring force and fluid pressure to fit the friction pair, it automatically maintains contact during operation and does not need to adjust the compression force like ordinary flexible packaging after assembly.

4. It has vibration resistance. When the speed is 3000r/min, the larger amplitude ≤ 0.05mm, and the PV value continues to increase.

5. Low power loss. Packing seals work by pressing packing against a shaft or sleeve. The packing seal is rubbed directly on the shaft. The tighter the holding pressure, the greater the friction and the greater the power consumption. The friction of the mechanical seal is in a semi-liquid friction state, the friction coefficient is very small, and the power loss of the mechanical seal is 10%-50% of the power loss of the packing seal.

6. The bellows sealing shaft or bushing is not worn, and it is not sensitive to the vibration of the rotating shaft and the deflection of the axial housing.

7. Wide range of application. When the medium is flammable, explosive, toxic and harmful, mechanical seal can ensure the seal. It is also suitable for sealing high temperature, low temperature, high pressure, vacuum equipment of various speeds and corrosive media.
