Analysis of explosion-proof tools development

Source: this site   Popularity:   The time of issue: 2013-03-02 13:18:00

The proof tools production began in the 1940s. Currently, in addition to the foreign, Japan, the United States, Germany, Russia and other countries also have a production capacity of explosion-proof tools. China since the early 1980s, led by the then Organization of Tianjin Municipal Economic Commission, by the Tianjin two light Bureau spanners Tool Company (now Tianjin metal tool company) to develop and produce the first batch of explosion-proof tools. And batch proof tools products sent to Japan for testing, inspection revealed that products fully comply with the standard requirements.

In the mid-1980s, the country has developed fifty-six explosion-proof tools, specializing in the production units, production varieties and specifications have been dozens of manufacturers and experts organized by the Ministry of Light Industry and work out our national explosion-proof tools standard ( GB 10686-89), (GB 10687 ~ 10693-89). Including: explosion-proof performance test method (with the the Japan test methods) octagonal hammer, explosion-proof, explosion-proof box wrench, explosion-proof checks hammer wrenches, explosion-proof, explosion-proof lid wrench. Modify the standard experience twice: the time standards released in 1999 by GB reduced to the recommended industry standards QB/T3872-1999. Then modified again in 2003 for QB/T2623.7-2003 still in use today. According to the instructions of the spirit to pay close attention to the safety work conference held by the National Development and Reform Commission in 2007 and the China Light Industry Federation (formerly the Ministry of Light Industry): called for the strengthening of standardization, the establishment of the system of production and access to quality inspection of explosion-proof tools and explosion-proof tools standard. According to the instructions, the State Light Industry proof tools quality supervision and inspection center responsible for the organization to develop a national mandatory standard of proof tools, and formally incorporated into the 2008 work plan and tasks. The standard of proof tools recommended industry standards promoted to the ranks of the national mandatory standards, standardization of work to develop a new foundation for the the proof tool industry standardization. 2008, the State Administration of Light Industry proof tools Quality Supervision and Inspection Center has overall responsibility for the organization related to production units and experts, reference to foreign standards, according to the actual situation of our country, to develop a new national standard discussion paper, after several modifications After discussion, reported the China Light Industry Federation and passed a full range of rigorous argument audit, has been reported to the China National Standard Committee pending.
1980s to the present time in two decades, China's explosion-proof tools manufacturing by the beginning of the five or six companies, more than a dozen product specifications, the development of the 30-some companies manufacture today, thousands of varieties specifications. China has gradually become the production base of explosion-proof tools, manufacturers from developed countries to China to find cooperation between manufacturers, procurement proof tools to meet the needs of the industry abroad is an inevitable trend. However, explosion-proof tools in the domestic market or in the production, use less abnormal state, has not been a comprehensive promotion and application, and even some of flammable, explosive high-risk industry almost has not been used. The survey found that actual work following main reasons:
1 a clear understanding of the explosion-proof tools, inaccurate positioning;
2, the security of the region and industry management department check is not stringent enough;
3, the high price of the explosion-proof tools, the running costs of the enterprise.
