试验机和油压控制系统的概述于1966年1月试制的最大负荷为3000 吨的液压拉力试验机是曾未有过的大吨位试验机,是为了用来与原子反应堆压力容器上所使用的钢板相同原度的试样进行大型试验而试制的(见图1)。
TESTING MACHINE AND HYDRAULIC CONTROL SYSTEM The hydraulic tension tester with a maximum capacity of 3000 tons, which was trial-produced in January 1966, was a large-tonnage testing machine that had not been used before to be used with a nuclear reactor pressure vessel Steel prototype of the same degree of large-scale trial and trial production (see Figure 1).
