Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard is the revision of CJ/T 3065-1997 "arc grille decontamination machine", compared with the CJ/T 3065-1997 main technical changes as follows.

--- Modify the definition of arc grille decontamination machine (see 3.1, 1997 version 3.1);

--- Increase the definition of scraping slag device, delete the definition of reliability,, Vice rake (see 3.6, 1997 version 3.5, 3.7, 3.9);

--- Modify the arc grille decontamination machine type, type, basic parameters (see 4.1, 4.2, 4.3, 1997 edition Chapter 4, Chapter 5, Chapter 6);

--- Increased arc grille decontamination machine average time to failure requirements, the deletion of the reliability requirements (see 4.3.1, 1997 Version 7.3.2);

--- Increasing the arc grille decontamination machine material (see Chapter 5);

--- Increasing the noise limit of arc grille decontamination machines (see 7.1.3, 1997 version 7.3.10);

--- Increased rake tooth penetration into the depth of the requirements of the arbor (see 7.2.1.6);

--- Increased arc grille decontamination machine on the safety ground, insulation resistance, tooth harrow rotation direction requirements (see 7.5);

--- Modify the arc grating, tooth harrow, drive, electrical control equipment, painting, lubrication test methods (see 8.2.1, 8.2.3, 8.4, 8.6, 8.7, 1997 version 8.6);

--- Increase scraping slag device, welding and processing of parts, security testing methods (see 8.2.2,8.3,8.5);

--- Removed the appendix (see the 1997 edition of Appendix A, Appendix B).
