标准摘要
[中文适用范围]： 此部分 ISO 21940 规定了适用于离心式动平衡机测量站的罩壳和其他防护措施的要求，旨在将源自此类机器中转子的机械危险降至最低。这些危险源于动平衡机在不同条件下使用各种转子进行运行时。此部分 ISO 21940 定义了不同的防护等级，规定了罩壳和其他防护措施提供的保护，并规定了每个防护等级的适用性限值。本部分 ISO 21940 不处理用于平衡转子质量分布的装置以及用于转子装卸的装置，即使它们与测量站相连。本部分 ISO 21940 不处理罩壳的特殊特性，如噪声降低、通风损失减少或真空（旋转带有叶片的转子达到平衡转速时可能需要真空）。 [外文原描述]： This part of ISO 21940 specifies requirements for enclosures and other protective measures used to minimize mechanical hazards produced by the rotor in the unbalance measuring station of centrifugal (rotational) balancing machines. The hazards are associated with the operation of balancing machines under a variety of rotor and balancing conditions. This part of ISO 21940 defines different classes of protection that enclosures and other protective measures provide and describes the limits of applicability for each class of protection. Devices for adjusting the mass distribution of a rotor and devices to transfer the rotor are not covered by this part of ISO 21940, even if they are combined with the measuring station. Special enclosure features, such as noise reduction, windage reduction or vacuum (which may be required to spin bladed rotors at balancing speed), are not covered by this part of ISO 21940.
