| Abstract: | According to the characteristics of polyester plant′s vacuum system, nitrogen pressure leak test-ing in cold state, freon pressure leak testing in hot state and vacuum helium leak detection in hot state arediscussed in this paper. The results show that the air tightness of the vacuum system is guaranteed by multi-ple leak detection and elimination of the polyester plant′s leakage points, and the device can be drivedsmoothly and stable operation. |
