Wang jun, director of the national explosion-proof electrical products quality inspection center, also director of the explosion-proof electrical equipment standardization technical committee members and explosion-proof electrical products production license examination department director of multiple identities, etc.
In the last six years, he says, industrial production permit system for the quality of products for fortification and the development of the industry as "charng-er's no.1" launch stability of equilibrium, always orbits around the quality without judgment.
Wang jun said that due to the explosive dangerous sites exist widely in all kinds of inflammable and explosive substances, so these places used in a variety of electrical products, must be from the electric parameters, structure design, selection of materials and components, manufacturing process, detection means and other aspects, comprehensive explosion-proof safety measures are taken, any link management oversight and quality problem could leave a safe hidden trouble or cause explosion accident, caused serious damages to personal and property security.
Because of this, explosion-proof electrical products for many years has been the focus of the national government departments to strengthen management objects.
As early as in 1986, the state began to explosion-proof electrical products production permit system, once during the interrupt.
Since it was established in 2000, "the general administration of quality supervision, inspection and quarantine, strengthened the involving personal and property safety supervision, public security and other important products, the first batch of expanding the scope of the implementation of the production license key products include the explosion-proof electrical, see its urgency." In nanyang explosion protected electrical research institute deputy chief engineer, secretary general of the China electrical industry association industry explosion-proof electric motor branch yun-sheng wang memories, the explosion-proof electrical products quality supervision has urgent situation.
In six years, in the national industrial products production license under the unified leadership of the office, in the national industrial products production license examination center, under the elaborate organization of through explosion-proof electric examination department, professional testing institutions and the efforts of all the examiner, for all kinds of explosion-proof electrical products production enterprise and the product quality strictly the on-spot inspection and product sampling, a total of all kinds of explosion-proof electrical products in 916 (hair) certificate. The general production enterprises with production license to work as an opportunity to perfect the means of production, enterprises improve the quality management level.
Explosion-proof electrical industry in China has been effectively specification, has realized from the source control explosion-proof electrical products quality goals.
Industrial production permit system not only fully cover the entire explosion-proof electrical industry, and also improve the overall level of the industry the quality of the products in time, the state supervision and spot check result of improved steadily is proof of that.
General administration of quality supervision, inspection and quarantine, respectively, in 2000, 2001, 2003, explosion-proof electrical products for the three country selectives examination, 2000 examined 47 the 47 kinds of products of the enterprise, among them, the factory use explosion-proof electric (explosion-proof switch and distribution box), product sampling percent of pass is 76.2%.
2001 random 33 companies 33 kinds of products, total percent of pass is 81.8%, among them, the factory use explosion-proof electrical product sampling percent of pass is 85.7%, factory use explosion-proof lamps and lanterns product sampling percent of pass is 75%.
2003 random 39 enterprises of 39 kinds of products, total percent of pass is 87.2%, among them, the factory use explosion-proof electrical product sampling percent of pass is 87.5%, factory use explosion-proof lamps and lanterns product sampling percent of pass is 86.7%.
In selectiving examination enterprises in 2003, obtained the production license of 18 companies all qualified, unqualified 5 companies are of similar products production license unlicensed companies.
Of permit system of explosion-proof electrical practice in our country, and the United States, Japan, the European Union and other developed countries of the explosion-proof electrical products quality and safety of unified regulatory approach is consistent with the government.
Through the implementation of the production license system, and some mature and perfect enterprise quality management has entered the stage of independent research and development, and lead the industry overall technical progress.
Type such as domestic large capacity increased safety brushless excitation synchronous motor has reached the world advanced level, are widely used in major national petrochemical engineering project
Explosion-proof electrical standards is also in line with international standards.
Over the years, the basis of explosion-proof products standard is gradually perfect.
At present, the national explosion-proof electrical equipment standardization technical committee according to IEC latest explosion-proof standards organization revision consummates the mandatory GB3836 electrical equipments used in explosive gas environment, GB12476 combustible dust environment using electrical equipment and other series of explosion-proof electrical basic standards.
At the same time, on the basis of these basic standards, system and revised the various types of explosion-proof electrical products industry standards.
