Comprehensive interpretation of the Roots fan standard

No Roots fan standards, you may buy the wrong equipment

Roots fan has always been an indispensable equipment in the industrial field, but, as we all know, there are many types of Roots fan, specifications and other differences, which not only makes it difficult for users to do accurate purchase, but also increases the later maintenance, maintenance costs and risks. So, there is no standard specification to measure, test the good and bad Roots fan? The following article will comprehensively explain the current Roots fan standards.

The reason for the standard

Nowadays, there are many domestic and international standards and specifications involving Roots fans, among which the European standards EN series (EN13445, EN286, EN12285) and ISO2858, etc. are widely used worldwide and have been adopted and applied by most of the Roots fan manufacturing enterprises. However, in our country, Roots fan standards are produced and revised every year, specifically because of the following aspects:

1. With the wide application of Roots fan, Roots fan models, specifications, the use of the environment, there are different degrees of difference, showing the Roots fan of different models, specifications in the use of the process of different problems and between the impact of factors;

2. In order to better and practically safeguard the interests of enterprises and the industry, strictly control product quality, reduce secondary pollution and failure rate, and enhance the effectiveness of the use of Roots fan, the development of Roots fan standards has become an industry consensus.

Classification of standards

Roots fan standards based on different standard content, can be divided into the following three categories:

1. Technical standards: can specify the technical parameters of the Roots fan, quality standards, performance indicators, inspection, testing, acceptance, maintenance and installation of the basic requirements.

2. Manufacturing standards: can specify the appearance and size of the Roots fan design, structure, technology, materials, processing, assembly, sealing and other aspects of the basic requirements.

3. Application standards: can stipulate the application scope of Roots fan, the use of conditions, safety, to ensure the quality of power supply, use and maintenance management and other aspects of the basic requirements.

Standard highlights

Roots fan standards cover a wide range, there are inevitably some minor differences. The following extracts the main content of the People's Republic of China national standard “corrugated wheel fan” (GB/T21556-2008) as the focus of this article, so that bystanders understand.

In-depth analysis of the concept of Roots fan and the form of application

Roots fan is a kind of volumetric fan, its basic interaction is to reduce the pressure inside the machine to achieve the effect of conveying gas. Because the actual flow rate is independent of the magnitude of the outlet pressure, Roots fans have demonstrated excellent pneumatic conveying capabilities in many applications, especially in industries such as industrial and agricultural virus prevention and control, disinfection and sanitation, where compression and suction are required.

Applications in industry translated into standard language

Roots fans are the preferred equipment for ventilation, liquid discharge and constant speed transmission in various industries. In the development, design, manufacture, use and standardization of Roots fans, there is a need to ensure the reasonableness, versatility and reliability of the products, and at the same time, require the upgradability and maintainability of the equipment in the process of use. This also puts forward high requirements for the development of standards for Roots fans, but this standard has not been fully popularized for various reasons.

The standard development program and operation mode

Roots fan standard-setting, should be the reconciliation of socialization and market-oriented. The standard will have a standardization of the industry's technology and manufacturing, will have a quality assurance of the enterprise's products, but also will give consumers a trust. The development of Roots fan standards need to take into account a number of factors, such as product structure, application range and so on. The core of the development of the program also lies in the development of standards for the team members of the information and technical capabilities of the enhancement of scientific and technological content, etc., to achieve the standard update and external expansion.

Quality Evaluation System for Standard Implementation

In the Roots fan standard implementation of quality evaluation system, should be developed before the standard collection, summarization, and screening. Scientific and technological content and health, environmental protection, energy saving content should be the focus, at the same time, these standards should also bring sustainable development to the manufacturing enterprises in the future, in order to avoid more users to get the product through some illegal channels, industrial chain failure and so on.

Exploration of standard defects

Although the Roots fan standard has been developed for many years, but in real life, it has not been completely popularized, and the standards between the industry are mostly different. At the same time, the standard also has some neutral and ambiguous problems, which creates certain difficulties for manufacturers and users to introduce and exercise their rights. This also adds a certain degree of difficulty to the correct use of Roots fans.

Conclusion

The above is a comprehensive interpretation of the Roots fan standard. As a reference in the Roots fan industry, the standard is crucial to the development of the whole industry. It is hoped that through this article, all the people in the related fields can understand the importance of the Roots fan standard and standardize the development of the industry.
