この概要は現在英語のみで提供しています。
適用範囲
This standard specifies the mandatory safety requirements for the design, manufacturing, and operation of foundry shakeout machines. It specifically applies to fixed inertial vibration shakeout machines and conveyor-type inertial vibration shakeout machines, as well as their integrated units and auxiliary equipment. It is essential for manufacturers and suppliers of foundry machinery to ensure full compliance. Impact-type and eccentric vibration shakeout machines may also refer to this standard.
技術要求
The standard comprehensively addresses various hazard categories including mechanical, electrical, thermal, and noise risks. For mechanical safety, it dictates specific structural requirements based on load capacities and operating temperatures, such as mandating upper vibration excitation for environments exceeding 40°C and dual-mass structures for fixed machines with loads over 200kN. All fasteners must meet minimum strength grades and incorporate anti-loosening measures. Regarding control and electrical systems, the standard requires reliable interlocking mechanisms and prohibits reverse braking for machines operating beyond the resonance zone. Emergency stop devices must be installed nearby and their reset must not cause automatic restart. Electrical systems must comply with GB 5226.1 and ensure proper grounding for exciters and drive motors. For environmental and material hazards, the standard sets strict noise limits (e.g., maximum 93dB(A) under no-load conditions) and requires the integration of dust extraction systems or sealed acoustic enclosures to mitigate dust inhalation and explosion risks.
試験方法
Compliance with the safety requirements is determined through a prioritized sequence of four methods: functional testing to verify safety component operations, instrumental measurement for quantitative limits like noise levels, calculation and drawing analysis for structural integrity and stability, and finally visual observation for qualitative checks and usage information review.
よくある質問
What products are regulated under GB 25492-2010?
It regulates fixed inertial vibration shakeout machines and conveyor-type inertial vibration shakeout machines used in foundries. It is a mandatory standard for these product categories.
What are the key noise limits specified in the standard?
Under no-load conditions, the noise sound pressure level must not exceed 93dB(A). If an electric exciter is used, the limit is stricter at 90dB(A). Manufacturers must also provide sealed or semi-sealed acoustic enclosures.
Does the standard reference international standards?
Yes, it aligns with several international practices by referencing equivalent Chinese adoptions of ISO standards, such as GB/T 15706.1 (ISO 12100-1) for basic safety concepts and GB 5226.1 (IEC 60204-1) for electrical equipment safety.
