1 Subject content and scope of application
This standard specifies the method for compiling the model of centrifugal extractors (hereinafter referred to as centrifugal extractors). 2 Method for compiling the model
JB/T724394
2.1 The model of the extractor consists of three parts: basic code, main parameters, and material code of the part of the drum that contacts the separated materials. The expression method is as follows:
Retrofit code
Material code of the part of the drum in contact with the separated material Main parameters
Basic code
2.2 The basic code of the extractor model is compiled according to the classification principle of class, group and type, and its code should comply with the provisions of Table 1. Class represents centrifugal extraction unit
High-speed centrifugal extractor
Represents the drum type: Type
Frequency type
Represents the basic structure of mixed extraction.
2.3 The main parameters of the lifting machine are expressed in terms of the nominal size of the maximum inner diameter of the drum, in mm. 2.4 The material code of the drum in contact with the separated material should comply with the provisions of Table 2. Approved by the Ministry of Machinery Industry on July 18, 1994

When the structure or performance of the extractor has been significantly changed, the modification code shall be added with capital letters A, B, C2.5 at the end of the original model in sequence to distinguish them.
Model marking example:
Chamber flow channel type centrifugal extractor. The maximum inner diameter of the drum is 560mm, the drum material is corrosion-resistant steel, the first modified design: CSL560-NA centrifugal benzene extractor
Tube orifice plate type centrifugal extractor, the maximum inner diameter of the drum is 105mm, the drum material is titanium alloy: CGK105T centrifugal extractor
Spiral static mixing centrifugal extractor, the maximum inner diameter of the large end of the drum is 450mm, the drum material is coated with a metal coating: CLJ450-J centrifugal extractor
Structural type
Extractors are classified according to their drum structure and extraction and mixing characteristics It can be divided into the following 10 types: a.
CSL type centrifugal lifting machine (see Figure 1);
CSK type centrifugal extraction machine (see Figure 2);
CDB type centrifugal extraction machine (see Figure 3);
CGK type centrifugal lifting machine (see Figure 4);
CTL type centrifugal extraction machine (see Figure 5);
CTX type high-core benzene extraction machine (see Figure 6);bzxz.net
CTC type centrifugal extraction machine (see Figure 7);
CLL type centrifugal extraction machine (see Figure 8);
CLJ type centrifugal lifting machine (see Figure 9);
CDJ type centrifugal extraction machine.
