Q8 U" G/ [) C" E( S 美国及西欧一些国家长期习惯于使用英制单位,又由于这些国家大量出口液压机械对世界各地区颇有影响,所以国际标准化组织颁布了米制系列和英制系列并行的缸筒内径和活塞杆直径标准,但是也明确规定各企业的产品应尽快向米制系列过渡,以便最后淘汰英制系列。我国的标准只规定了米制系列。表1至表4是缸筒内径和活塞杆直径的标准系列参数。 表1 缸内径(米制系列) (mm) ISO3320 | GB2348-80 | JB826-88 | ISO3320 | GB2348-80 | JB826-88 | 8 | 8 | | 125 | 125 | 125 | 10 | 10 | | | | (130) | 12 | 12 | | | (140) | 140 | 16 | 16 | | | | (150) | 20 | 20 | 20 | 160 | 160 | 160 | 25 | 25 | 25 | | (180) | 180 | 32 | 32 | 32 | 200 | 200 | 200 | 40 | 40 | 40 | | (220) | (220) | 50 | 50 | 50 | 250 | 250 | 250 | | | 55 | | | (280) | 63 | 63 | 63 | 320 | 320 | 320 | | | (65) | | | (360) | | | 70 | 400 | 400 | 400 | | | (75) | | | (450) | 80 | 80 | 80 | | 500 | 500 | | | (85) | | | (560) | | (90) | 90 | | 630 | 630 | | | (95) | | | (710) | 100 | 100 | 100 | | | 820 | | | (105) | | | (900) | | (110) | 110 | | | 1000 |
