The importance of fluid mechanical seal technology

　2016-12-05　　

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

In 1984, the chlorine leak at the United Pesticide Plant in Bhopal, India, which shocked the world, caused 2,500 deaths and 100,000 hospitalizations, and a large number of food and water sources in the nearby areas were contaminated;

In 1989, the leak of isobutane in the poly-ethylene equipment of the Texas petrochemical plant in the United States caused an explosion, and the loss reached 730 million US dollars;

In the same year, the Ufa LNG pipeline leaked and exploded, killing 645 people. According to statistics, in the daily use and maintenance of machinery and equipment, about 40% to 50% of the working screens of the T pump are used for the repair port of the shaft seal, and about 70% of the repair cost of the centrifugal pump is used to deal with the seal failure. .

Mechanical seal technology workers in the United States have discovered that due to the development of seal technology, only steam turbines can save 300 million U.S. dollars in energy costs each year. It can be seen that the fluid mechanical seal technology is not only an effective means to solve the leakage of machinery and equipment to achieve safe production, but also a guarantee for saving resources and protecting the environment, which has attracted widespread attention from all over the world.　　179.html,
