【 Weak current College 】 compressor standard system components and standard application guide-Power By 【 China power house network 】

As China's rapid economic development, the compressor products in various fields and widely used, and users of products quality and more. Market economy, import and export trade, product certification, licensing, and so on, are built around the theme of quality of products. And support this important foundation and — compressor standards is increasingly accentuates its importance, but also more and more of the parties concerned and attention. Therefore a comprehensive understanding of the industry standard, familiar with the standard content, a good application of standards, in order to improve product quality, strengthening product in market competitiveness, market access, and the expansion of international trade, are essential. This article will more systematically describes our compressor standard system constitutive principles, standard system levels, compressors of various major standard content and scope of application, as well as on the recent development of the compressor standard for a brief description of the dynamic, with a view on the use of standard compressor units and related personnel to help and provide guidance on the application.

Compressor standard system constitute

㈠ our compressor standard level and development agencies

According to the Standards Act provides that the standard is divided into China compressor national standards, industry standards and enterprise standard three-class. These national standards and industry standards is the national scope should follow or recommend the use of standards. These compressors country or industry standard basically consists of the national standardization Technical Committee responsible for developing the compressor. Chemicals, coal, ships, military and other industries also have a small amount of compressor standards. Enterprise standard by compressor production enterprises to develop and enforce in the enterprise. This article focuses on the standardization of the national focal point for the compressor of the various types of compressors.

㈡ compressor standard system constitutive principles

1, compressors, involving many types of standard surface is also very broad. According to the different compressor classification, you can build different standard system. International standard classification of ISO5390 the compressor and the equivalent of the international standards are used in standard GB4976 classification according to the structure. This taxonomy comparison with scientific rigour, not overlapping intersections. So our compressor classification according to the structure of the standard system, this principle, different levels and different content of compressor standards.

2. press the structural classification of compressor are positive displacement compressors and pneumatic compressor. In theory, positive displacement compressors with compressed media compressor, it is customary to refrigeration compressor zoned cooling device. Power turbine compressor, the compressor has the injector and the like, our industry practices are the fall fan industry. Therefore, the compressor standard system defined by the standard is primarily concerned with positive displacement compressors category, including its spare parts, accessories and reprocessing installations, but does not include refrigeration compressors. This is to identify the standards system of the other principles.

㈢ compressor standard system levels

Compressor standard system is divided into three layers.

The first layer is the basis and method for standards. These standards are integrated in the standard, generally apply to the various positive displacement compressors.

The second level of safety and product standards. These standard basic classification by compressor structure and determine the specific requirements of the various compressor performance parameters and manufacturing inspection requirements and safety requirements must be met.

The third floor is for parts and material standards, these standards are standard for products or services and supporting the use of the product standard.

Three-layer standards, the first layer is the base, there is no such standard, second-tier criteria cannot expand, performance will not be able to identify the product.
