Preface
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting.
This document is modified to adopt ISO 6022.2006 "Installation dimensions of hydraulic transmission 25 MPa (250 bar) series single-rod cylinders".
This document has made the following structural adjustments compared to ISO 6022.2006.
---Added Chapter 6;
--- Chapters 7 to 9 correspond to Chapters 6 to 8 of ISO 6022.2006;
--- Table 6 and Table 8 correspond to Table 5 and Table 6 in ISO 6022.2006 respectively.
The technical differences between this document and ISO 6022.2006 and their reasons are as follows.
--- The scope of application has been changed (see Chapter 1) to adapt to my country's technical conditions and improve operability;
--- ISO 5598 (see Chapter 3) has been replaced by the normative reference GB/T 17446 to adapt to my country's technical conditions and improve operability.
Sexuality;
--- Added "D", "Y" and "PJ" basic dimensions (see Figure 1, Table 1), the "VE" of the cylinder diameter 140 was changed from "48" to "45", and the cylinder diameter 180
The "ZJ" of the system was changed from "497" to "500" (see Table 1) to adapt to my country's technical conditions and improve operability;
--- Added the basic dimensions of four cylinder diameters of 90, 110, 220 and 280 (see Table 1 to Table 6) to adapt to my country's technical conditions;
--- ISO 4395 (see 8.2, Table 1) has been replaced by the normative reference GB/T 2350 to adapt to my country's technical conditions and improve the reliability of the product.
Operability;
--- Deleted the MP4 and MP6 installation types in Figure 3, Table 3 and Chapter 6 of ISO 6022.2006, and changed the dimension “L
or LT" was changed from "113" to "100", and the size "MR or MS" was changed from "113" to "100" (see Figure 3 and Table 3) to accommodate our
The technical conditions of the country improve operability;
---Change the size "ZB" of cylinder diameter 180 from "502" to "505" (see Figure 4, Table 4) to adapt to my country's technical conditions and improve the reliability.
Operability;
--- Added MS2 installation type (see Figure 5, Table 5 and Chapter 7) to adapt to the actual installation size of hydraulic cylinders in my country;
---Change the thread tolerance grade "6g" of the oil port "EE" in ISO 6149-1 to "6H", and delete the thread tolerance grade "6g" of the oil port "EE" in ISO 1179-1.
The thread tolerance grade "6g" of ISO 6164 and ISO 6162-1 is changed to "6H" (see
Table 6), in order to adapt to my country's technical conditions and improve operability;
--- Added the "English" series corresponding to the "Metric" series in the ISO 6164 and ISO 6162-1 oil port flange nominal diameter DN (see
Table 6), making it more convenient to select;
---Change the ISO 6162-1 oil port installation dimension "FF" from "12.7" to "13" for cylinder diameters 63 and 80, and change the ISO 6162-1 oil port installation dimension "FF" from "12.7" to "13" for cylinder diameters 100 and 125
ISO 6162-1 oil port installation dimensions "FF" and "EA" changed from "19.1" to "19.2" and "22.3" to "22.2"; cylinder diameter
The ISO 6162-1 port installation dimension "FF" of 140, 160, 180 and.200 has been changed from "25.4" to "25.6";
The ISO 1179-1 oil port installation size "EC" of 320 is changed from "32" to "36", and the ISO 6149-1 oil port installation size "EE" and
"EC" changed from "M60×2" to "M48×2", "32" changed to "36", ISO 6162-1 oil port installation size "FF" changed from "31.8"
Changed to "32" (see Table 6) to meet my country's technical requirements;
--- ISO 6099 (see 4.3) has been replaced by the normative reference GB/T 9094 to adapt to my country's technical conditions and improve operability.
Sexuality;
--- ISO 3320 (see Chapter 5, Table 1) has been replaced by the normative reference GB/T 2348 to adapt to my country's technical conditions and improve
Operability;
--- Added "travel limit deviation" (see Chapter 6) to adapt to my country's technical conditions;
--- The limit deviation value of stroke "S > 8000" and the limit deviation of installation size (see Table 7 and Table 8) have been added to adapt to my country's technology
condition;
--- Added requirements for the type and size of piston rod ends (see 8.2) to adapt to my country's technical conditions and improve operability;
--- ISO 8132 (see 8.3) has been replaced by the normative reference GB/T 39949.1 to adapt to my country's technical conditions and improve operability.
Acting nature.
The following editorial changes were made to this document.
--- In order to coordinate with the existing standards, the name of the standard is changed to "Installation Dimensions of Hydraulic Transmission 25MPa Series Single Rod Cylinders";
---The drawing was redrawn according to my country's mechanical engineering drawing standards;
--- Additional information on size selection values is added to Tables 1 to 6;
