Recently, the State Quality Inspection Administration announced the 29 of the 7 provinces, municipalities directly under the central government, 29 enterprises producing (not related to export products) mechanical transmission parts product quality supervision and spot checks of the results. Product sampling qualified rate is 99.5%. 3 unqualified enterprise products to be exposed, they are Wenling Jinna mechanical transmission parts factory submersible pump with mechanical drive, Wenzhou mechanical transmission parts factory rubber bellows mechanical transmission, Ningbo Bao and transmission parts manufacturing Co., Ltd. rubber bellows mechanical transmission. Spot checks of the provinces and cities including Liaoning, Shanghai, Tianjin, Jiangsu, Zhejiang, Sichuan, Shaanxi etc.. Sampling the recommended national standards JB/T4127.1-1999 "mechanical transmission technology conditions", JB/T6619.1-1999 "light mechanical transmission technology conditions", JB/T6373-1992 "welded metal bellows mechanical transmission technology," GB/T14211-1993 "," mechanical transmission test method JB/ T6619-1993 "light mechanical transmission test method," JB/T7369-1994 "mechanical face flatness inspection method" etc. the standard requirements, the hard drive mechanical transmission parts ring flatness, Shi Mohuan and PTFE bellows leakage, tolerance, the main parts of the hydrostatic pressure test, air tightness leakage, leakage, running test running test of wear 7 items were tested.

抽查结果表明，一是通过国家监督抽查促进了企业质量意识的提高，加强了质量管理，此次抽查的硬质传动环平面度、石墨环和四氟波纹管渗漏、主要零件公差、静压试验泄漏量等项目单项符合率达到100%。二是市场占有率较高的大型生产企业产品质量较好，所检项目全部达到国家标准规定的要求。

Sampling results show that, one is through the national supervision and spot checks to promote the enterprise quality awareness, strengthen quality management, the hard drive in the sample loop flatness, Shi Mohuan and PTFE bellows leakage, tolerance, the main parts of the hydrostatic test leakage project individual line rate of 100%. The two is a higher market share of large enterprises better product quality, the seized items all meet the national standard requirements.

抽查中发现的主要质量问题是：

Sample found in the main quality problems are:

1.个别产品运转试验泄漏量不合格。

1 individual products running test leakage failure.

标准规定，当传动介质为液体时，机械传动运转试验的平均泄漏量：轴（或轴套）外径不大于50mm时，泄漏量不大于3ml/h；轴（或轴套）外径大于50mm时，泄漏量不大于5ml/h。抽查中有个别产品运转试验泄漏量不合格。其中有一种产品运转试验时因橡胶波纹管断裂而发生喷漏，致使运转试验无法继续进行。另一种轴径为35mm产品，各测量时间单元中最大的平均泄漏量为31.5ml/h，超过标准规定的要求。

Standard, when the transmission medium is liquid, the average amount of leakage of mechanical transmission test: the shaft (or sleeve) diameter is less than 50mm, the leakage is not more than 3ml/h; the shaft (or sleeve) diameter is larger than 50mm, the leakage is not more than 5ml/h. Spot checks of individual product operation test leakage failure. One product operation test for the rubber corrugated tube rupture and spray leakage, resulting in running test cannot continue. Another axis of 35mm products, each measuring unit of time of the maximum average leakage rate of 31.5ml/h, exceeds the standard requirements.

2.个别产品碳石墨传动环磨损量不合格。为了满足机械传动使用期的要求，JB/T4127.1-1999《机械传动技术条件》标准规定，以清水为介质进行试验，运转100h软质材料的传动环磨损量不大于 0.02mm。抽查中个别产品石墨传动环磨损量超过标准规定的要求。

2 the product of individual carbon graphite drive ring wear failure. In order to meet the requirements of mechanical transmission using JB/T4127.1-1999 "technical conditions" provisions, mechanical transmission standard, with water as the medium of transmission test, 100h soft material ring wear amount is not more than 0.02mm. Spot checks of individual products in graphite drive ring wear amount exceeds the standard requirements.

3.个别产品气密性试验不合格。JB/T6619.1-1999《轻型机械传动技术条件》标准规定，轻型机械传动产品出厂前，应将每套产品在最高工作压力下做气密性试验，持续1min不得有可见气泡。抽查中有个别产品气密性试验不合格。

Unqualified 3 individual products air tightness test. Regulation of JB/T6619.1-1999 "conditions" light mechanical transmission technology standard, light mechanical transmission products before leaving factory, each product should be done air tightness test at the highest working pressure, continuous 1min has seen no bubble. Checks are unqualified individual products air tightness test.
