Importance Of The Use Of Fluid Mechanical Sealing Technology

The fluid mechanical seals used in mechanical production applications, especially in the process industry, are generally facing the risk of leakage. Leakage will not only cause energy waste, material loss, environmental pollution, but also lead to fire, cause explosions, directly endanger personal safety. Mechanical seals are small, but they determine the safety, reliability and durability of machinery and equipment. Especially the machinery and equipment of petrochemical enterprises, most of the media treated have corrosive, toxic or flammable, explosive characteristics, and accompanied by high pressure and temperature, once leakage, often will cause major accidents.

In 1984, the world was shocked by the chlorine gas leak at the United Pesticide Plant in Bhopal, India, which killed 2,500 people, hospitalized 100,000 people and contaminated a large amount of food and water in nearby areas;

In 1989, an isobutane leak in a gasified ethylene plant in Texas Petrochemical Plant caused an explosion, resulting in a loss of $730 million.

In the same year, a leaking liquefied natural gas pipeline exploded in Ufa, Russia, killing 645 people. According to statistics, in the daily use and maintenance of machinery and equipment, about 40% ~ 50% of the working fireflies of the T machine pump are used for the maintenance of the shaft seal, and about 70% of the maintenance costs of the centrifugal pump are used to deal with the sealing failure.

Mechanical seal technicians in the United States have found that because of the development of sealing technology, steam turbines alone can save $300 million a year in energy costs. It can be seen that fluid mechanical sealing technology is not only an effective means to solve the leakage of machinery and equipment to achieve safe production, but also a guarantee to save resources and protect the environment, which has attracted widespread attention from all over the world.
