Related Introduction

The importance of the use of fluid mechanical seal technology: The fluid mechanical seal used in mechanical production applications, especially in the process industry, is 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.

It can be seen that 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 countries in the world.
