该机主要用于大规格的各式链条、锚链、钢丝绳等柔性试件的静拉伸或金属结构件的拉伸和压缩试验。还可做不过零的低频交变负荷疲劳试验.该机的主机采用全液压驱动,如拉或压的加荷,活动横梁的移动和锁紧等.另外主油缸活塞杆导向还采用了液体静压轴承。该机的电控采用了内装计算机的数字模拟混合式结构。负荷、位移、周期记数为数显,x-y记录仪可以绘出负荷-位移试验曲线。该机的控制系统通过伺服阀、负荷传感器等可实现闭环控制.该机的函数发生器
The machine is mainly used for large-scale all kinds of chain, anchor chain, wire rope and other flexible specimens static tensile or tensile tensile test of metal structures. But also zero but zero frequency alternating load fatigue test.The machine’s host using full hydraulic drive, such as pull or pressure loading, moving beam movement and locking, etc .. In addition the main cylinder piston rod guide also uses a liquid static Pressure bearing. The machine’s electronic control uses a built-in computer digital analog hybrid structure. Load, displacement, periodic counting is significant, x-y recorder can draw load - displacement test curve. The machine’s control system through the servo valve, load cell, etc. can be closed-loop control of the machine’s function generator
