Application of Bellows Mechanical Seals

Nowadays, the quality of water supply is directly related to the completion of oilfield production tasks and the stability of people's lives. Water supply equipment is the heart to ensure safe and reliable operation. The performance of the mechanical seal for water pump is one of the direct factors to ensure the continuous and reliable water supply. 

The characteristics of mechanical seal

Compared with ordinary packing seal, bellows mechanical seal not only has the advantages of good sealing performance and long service life but also has better energy-saving effect, it improves the working environment of the operation post, reduces the labor intensity of the workers and avoids accidents, such as bearing burning and motor burning caused by stuffing and water piercing. Its good effect has considerable economic and social benefits.

The applied range of mechanical seal

‍

The mechanical seal is a kind of shaft seal device of rotating machinery, which is composed of a pair of dynamic and static rings of vertical rotating axis under the action of flow pressure and compensation mechanism, keeping close and relatively sliding to prevent fluid leakage. Metal bellows mechanical seal is a new type of mechanical seal developed in 1997 with reference to the high and new technology of similar foreign products. Its main features are compact structure, convenient loading and unloading, good floatability, compensation for axial displacement of slow balance seal ring due to wear and vibration, and self-following dynamic relief. The utility model has the advantages of less dew point, strong anti evacuation ability and longer service life than other sealing materials by more than 3 times.

In recent years, bellows mechanical seal has been widely used in petroleum and petrochemical industries, it is suitable for various fluid media, especially for high temperature, high pressure, particle impurities, strong corrosion and other medium. With excellent quality, it has been put into use in various oil fields, petrochemical oil refining, sewage treatment, aluminum industry and pump plants since 1998. It has achieved satisfactory performance in all aspects and it is favored by users.
