根据聚酯装置真空系统特点,讨论了在开车前的冷态氮气加压试漏、热态氟利昂加压试漏和热态真空氦检漏技术。结果表明:通过多次检漏并消除聚酯装置漏点,确保真空系统无泄漏,保证在开车和正常运行过程中真空系统的气密性,使装置开车顺利,运行稳定。
According to the characteristics of the polyester vacuum system, the cold nitrogen pressure test, the hot fluorine pressure test and the hot vacuum helium leak test before driving are discussed. The results show that the leak detection of the polyester device can be ensured by multiple leak detection and elimination of leakage of the polyester device, ensuring the air tightness of the vacuum system during driving and normal operation, and driving the device smoothly and running stably.
