Preface
This standard is a revision of JB/T6924-93 "Drying Equipment Model Preparation Method". This standard has changed from JB/T6924-93 in the following main technical contents. - Clarify the structure of the model and stipulate that the order of the parts cannot be changed; - Add various feature codes:
- Add specific provisions for the main parameters.
This standard will replace JB/T6924-93 from the date of entry into force. This standard is proposed and coordinated by the Drying Equipment Standardization Technical Committee of the Ministry of Machinery Industry. The unit responsible for drafting this standard is Liaoning Tieling Drying Technology Research Institute. The main drafters of this standard: Zhao Jian, Sun Deyong, Zhang Yujie, Liu Lina, Zhang Haitao, Liu Guoquan, Gao Xiaofeng. 1 Scope
Machinery Industry Standard of the People's Republic of China
Drawing method of product model for drying equipment
This standard specifies the preparation of drying equipment model numbers Method This standard is applicable to the preparation of various drying equipment models that remove moisture contained in materials by vaporization. 2 Composition of drying equipment model
2.1 The drying equipment model consists of basic code and auxiliary code. JB/T 69241998
JB/T6924-93
The basic code consists of professional code and feature (including main features and auxiliary features) code. The auxiliary code consists of the main parameters of the equipment and the code of the improved design sequence.
2.2 For equipment with digital structures such as multi-layer, multi-segment, and multi-axis, Arabic numerals representing the number of layers, segments, axes, etc. may be added before the model number. 2.3 The specific expression method and inner core of the drying equipment model are as follows: basic code
auxiliary code
5||tt| |1 is the professional code. It is represented by the first letter of the Chinese pinyin \Gan\ (printed capital) representing the word "gan" for drying equipment. 2 is the main feature (main drying equipment type) code in the feature code. Use one of the drying equipment type names. The first (or second) letter of the Chinese pinyin of (or two) keywords (in capital letters) is specified in Table 1. 3 is the auxiliary feature in the feature code (structural form of main equipment, dry explosion method). ) code, represented by one (or two) letters (in capital letters) that constitute the name of the auxiliary feature. See Table 2 for details. 4. The main parameters of the commonly used main drying equipment should be specified in Table 3. The main parameters of drying equipment not included in should be expressed by the design main parameter values ??of each drying equipment. The measurement unit is determined based on the equipment and strives to simplify the model. The main parameter values ??in the model are generally rounded up into alarm numbers, || tt||5 is the code for the improvement design sequence. That is, when the equipment structure is greatly improved or the structure of some parts of the basic model is greatly improved, the main parameters of the original product model should be followed by the sequence of the improved design. Add A, B, and C. Note that the order between 1, 2, and 3 in the basic code cannot be changed. 2.4 The basic code in the drying equipment model should select the main characteristics, and the total number of letters should generally not exceed four. 2.5 In the drying equipment model, the main feature code adjacent to the professional code "G" shall not be "B\", and the letters adjacent to the main parameters shall not be I or 0.x.
2.6 The basic code of the same product model has characteristics other than those listed in Table 1 and Table 2 (for example, when a special structure is required, the Ministry of Machinery Industry approved it on 1998-03-19 ||tt| |1998-07-01 When implementing

formula, drying method and other characteristics) code, the code letters should be determined according to the principles specified in 2.3, so The determined letters should not repeat the existing code letters in this standard in the feature codes of the same type (such as "main" features or "auxiliary features, etc.).
