Compliance overview
Scope and applicability
This standard applies to various industrial separators, including disc separators, tubular separators, and chamber separators. It specifies the safety requirements and measures that must be followed during the design, manufacturing, installation, use, and maintenance of these machines. It is applicable to manufacturers and users of industrial separation equipment operating in the Chinese market. The standard addresses major hazards but does not cover all potential risks associated with these machines. It is primarily intended for equipment used in industries such as food, pharmaceuticals, and chemicals.
Technical requirements
The standard outlines comprehensive safety requirements, with Chapters 6, 7, 8, 9, and Appendix A being mandatory. It mandates rigorous frequency and strength checks for major stressed components to prevent mechanical failures. Manufacturers must ensure proper design of protective devices, hydraulic/pneumatic systems, and explosion-proof measures for hazardous environments. Material selection is strictly regulated, requiring material quality certificates and mechanical performance verification for the separator bowl and main shaft. Welding procedures for the bowl must be performed by certified personnel, with strict limitations on repair attempts and mandatory non-destructive testing (NDT) to ensure structural integrity. The standard references several other GB and JB standards for welding and material testing. Furthermore, the standard requires comprehensive product and technical archives to be maintained by the manufacturer. Manufacturers must also provide detailed user manuals and safety signage to guide safe installation, operation, and maintenance.
Testing methods
Safety performance is evaluated through a combination of document review, visual inspection, and physical testing. Key testing methods include: - Document Verification: Checking frequency and vibration calculation reports, material quality certificates, welder qualifications, and NDT reports. - Physical Measurement: Actual testing of noise and vibration levels according to referenced standards. - Visual Inspection: Assessing protective devices, safety signage, and explosion-proof features. - Dynamic Balancing: Verifying the dynamic balance precision of the separator bowl. Compliance is determined by a sampling inspection plan, where all key items must meet the standard, and at least 85% of major items must pass.
