问题的提出 在 1999年对秸秆切碎机安全检查中,我们发现由于企业生产中执行的标准不统一,在对切碎转子进行动平衡测定时,无法确定切碎转子应采用的平衡品质等级是 G 6.3级还是 G16级。造成此问题的原因有三个: 1.切碎转子动平衡测定方法的两个参照标准 (即 JB/T512
Problems raised In the 1999 straw chopper safety inspection, we found that due to the implementation of enterprise standards are not uniform, when the dynamic balance of shredding rotor determination, can not determine the balance of shredding rotor should be used is the level of quality G 6.3 or G16 level. There are three reasons for this problem: 1. Two reference standards for shredding rotor balancing (ie, JB / T512
