Recently, AQSIQ announced on the 7 provinces, 29 municipalities of 29 production (not related to exports) mechanical seals of product quality supervision and spot checks of the results. Products quality sample pass rate of 99.5%. 3 failed company's products are exposed, they are satisfied Wenling City, submersible pump mechanical seal mechanical seal factory, Wenzhou City, rubber bellows mechanical seal mechanical seal factory, Ningbo Manufacturing Ltd Po and the seal rubber bellows mechanical seal.

Sampling of provinces and cities, including Tianjin, Liaoning, Shanghai, Jiangsu, Zhejiang, Sichuan and Shaanxi. Random according to recommended national standard JB/T4127.1-1999 "mechanical seal technology", JB/T6619.1-1999 "light mechanical seal technology", JB/T6373-1992 "welded metal bellows mechanical seal technology" , GB/T14211-1993 "mechanical seal testing methods", JB/T6619-1993 "light mechanical seal testing methods", JB/T7369-1994 "mechanical seal face flatness testing methods" and other standard requirements for mechanical seals product flatness hard seal ring, graphite ring and PTFE bellows leak, the main part tolerances, air tightness, pressure leakage test, running test leakage, wear, etc. running test 7 projects have been tested.

Sampling results show that, first, through the national quality supervision and spot checks to promote awareness of enterprises, strengthen the quality of management, the checks of the hard seal ring flatness, graphite ring and PTFE bellows leak, the main part tolerances, static pressure individual test items such as leakage rate of 100% compliance. Second, higher market share of better product quality, large-scale manufacturing enterprises, the seized items all meet the national standard requirements.

Spot checks found in the main quality problems are: 1. Individual products running test leakage failure.
