製作液壓萬能試驗機油缸的材料

濟南試驗機廠分享製作液壓萬能試驗機油缸用的什麼材料，一般要看我們要應用到什麼地方，不同工作壓力的液壓萬能試驗機，我們所用的材料也是不一樣的，在製作時要考慮到能否適應工作壓力環境！

Ji'nan test machine share what material hydraulic universal testing machine cylinder is used,to see what we should be applied to different places, the working pressure of the hydraulicuniversal testing machine, our material is not the same, in the production should consider when can adapt to work pressure environment!

首先在一些重工企業常用超大負荷的液壓萬能試驗機，這種液壓萬能試驗機由於工作壓力較高，常採用20號、35號或者45號無縫鋼管材料製作。其中，20號無縫鋼管材料，因其機械性能較低，且不能調質，故現在很少使用了。需要與缸蓋、管接頭、耳軸等零件焊接在一起的缸體，可用35號無縫鋼管材料製作，並在粗加工後進行調質。用螺紋與其他零件鏈接的缸體，可採用45號鋼調質到HB241至285區間。

At first, some enterprises use large heavy load hydraulic universal testing machine, the hydraulic universal testing machine with high working pressure, often with No. 20, No. 35 andNo. 45 seamless steel tube material. Among them, 20 seamless steel tube material, because of its lower mechanical properties, and can not be quenched and tempered, is now rarely used. Need to joint, and cylinder head, tube parts such as cylinder trunnion welded together,making available 35 seamless steel tube material, and quenching and tempering in the rough machining. With the threads of the cylinder body and other parts link, can adopt 45 steelquenched and tempered to HB241 to 285 range.

那麼對於工作壓力較低的液壓萬能試驗機則可採用高強度的鑄鐵製作油缸；對於工作壓力較高的液壓萬能試驗機，可採用無縫鋼管材料製作其油缸。

So for the hydraulic pressure lower universal testing machine can produce cylinder made of cast iron with high strength; high working pressure for hydraulic universal testing machine,can make the oil cylinder adopts the seamless steel tube material.
