BW型拉杆式轴横向波纹补偿器 BW-based horizontal axis rod type bellows compensator Page38 BW型拉杆式轴横向波纹补偿器由三个不锈钢波纹管、中间接管、拉杆、二端面法兰、耳板等零件组成，它能吸收任意平面内的横向、轴向及它们的合成位移。按结构不同可分为大拉杆式和小拉杆式两种，其中大拉杆式（DL型）可把轴向位移限定在一定范围内。产品上的拉杆不是承力构件，当需要承受拉力推力时，需另行注明。 BW-based horizontal axis rod type bellows com-pensator is made up of three stainless bellows, mid connecting pipe, pull rod, bi-side flange, and ear plate etc. It can absorb any transverse, axial and compound displacement. The product can be classified as large rod type and small rod type, among which the large rod type (DL type) can restrict axial displace-ment to a certain extent. Because the pull rod of the product is not load-bearing components, it should be noted additionally if the rod should bear pull or thrust. 技术特性表：(DL、XL 三种产品相同，表中均以1.0MPa工作压力参数) Technical characteristics table :( DL, XL the three products are the same, the working pressure is 1.0Mpa in the table) 公称通径mmnominal diameter 波数wave number 波级管有效面积cm2effective area of bellows x。轴向补偿量 y。横向补偿量 kx。轴向刚度 ky。横向刚度 axial compensation horizontal compensation axial rigidity transverse rigidity 产品长度1000mm product length 产品长度1500mm product length ±x。 ±y。 kx。 ky。 ±x。 ±y。 kx。 ky。 40 8+8 21 9.8 95 130 1.3 9.8 142 130 0.7 50 8+8 41 12 100 150 1.5 12 150 150 0.8 65 6+6 61 20 120 190 2 20 180 190 1.1 80 6+6 82 30 130 245 4.5 30 195 245 2.3 100 6+6 125 40 112 275 6.8 40 168 275 3.5 125 6+6 180 50 95 300 13 50 143 300 7 150 6+6 255 60 80 375 24 60 120 375 13 200 6+6 480 70 81 500 58 70 121 500 35 250 5+5 730 70 75 750 120 70 113 750 72 300 4+4 1020 80 70 825 135 80 105 825 68 350 4+4 1280 80 56 900 210 80 84 900 108 400 4+4 1580 80 55 980 325 80 83 980 170 450 4+4 1980 90 48 1000 468 90 72 1000 258 500 4+4 2450 110 42 1050 651 110 63 1050 358 600 4+4 3450 110 40 1100 962 110 60 1100 529 700 4+4 4740 130 38 1150 1050 130 57 1150 578 800 4+4 5960 130 38 1200 1320 130 57 1200 728 900 4+4 7560 160 36 1250 1450 160 54 1250 875 1000 4+4 9280 160 35 1300 1680 160 53 1300
