This document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents"
Drafting:
This document replaces GB/T 9485-2003 "Radial Turbocharger Connection Dimensions": Compared with GB/T 9485-2003, except for the
In addition to structural adjustments and editorial changes, the main technical changes are as follows:
a) Changed the scope (see Chapter 1, Chapter 1 of the:2003 edition);
b) The mutual position dimensional standards and requirements of some superchargers have been changed (see 4:1, 2:1 of the:2003 edition);
c) Added relevant requirements for superchargers with compressor impeller outlet diameters of 40mm~60mm (see Table 1~Table 6);
d) Changed the connection size of the supercharger gas inlet and outlet with a compressor impeller outlet diameter of 60mm~140mm (see Table 2~
Table 5, Table 2~Table 5 of the:2003 edition);
e) The compressor inlet clamp connection and connection dimensions are added (see Figure 6 and Table 2);
f) Added compressor outlet plug-in connection, clamp connection and connection dimensions (see Figure 11, Figure 12 and Table 3);
g) The turbine inlet three-hole single inlet flange connection and connection dimensions are added (see Figure 18 and Table 4);
h) The connection dimensions of the four-hole square single inlet and double inlet of the turbine inlet have been changed (see Figure 20, Figure 21 and Table 4,:2003 version
Figure 14 and Table 4);
i) The irregular-shaped flange connection and connection dimensions of the turbine outlet have been added (see Figure 34 and Table 6):

3 Terms and definitions
There are no terms or definitions to be defined in this document:
4 Technical requirements
4:1 Mutual position dimensions of superchargers
The mutual position dimensions of the superchargers (as shown in Figure 1) should comply with the requirements of Table 1:
a) Front view b) Side view
Index symbol description:
J ---The size from the outlet center of the compressor casing to the center of the rotor; K ---The size from the outlet end of the compressor casing to the center of the rotor;
L --- Dimension from turbine shell inlet flange hole center to rotor center; H --- Dimension from turbine shell inlet flange surface to rotor center;
R --- the size from the outlet center of the compressor casing to the center of the turbine casing inlet flange hole; S --- the size from the inlet end of the compressor casing to the center of the turbine casing inlet flange hole;
T---dimension from the outlet end surface of the turbine shell to the center of the turbine shell inlet flange hole:
The structure may be different from that shown in the figure, but the specified dimensions should be followed:
