首先按照控制方式的不同，數(shù)顯式和屏顯式通過手動操作送油閥和回油閥來控制進入油缸的流量,微機控制電伺服的是通過電腦操作液壓伺服閥來控制的.在顯示數(shù)據(jù)方面有所不同,數(shù)顯式的主要顯示力值、強度、力,時間曲線和具有明顯屈服性能材料的屈服強度;屏顯式和微機控制電伺服的顯示各種力值、強度、延伸率、斷裂強度、上下屈服點、彈性模量以及多種試驗曲線.

Firstly, according to the different control modes, digital display andscreen display by manual operation of oil supply valve and the oil returnvalve to control the flow into the cylinder, the microcomputer control servois controlled by the computer operation of hydraulic servo valve. Differentdata on the display, digital display, the main force strength, force time curve and the yield strength, yield properties of materials; the screen display and computer controlled electro servo display all kinds of stress,strength, elongation, tensile strength, yield point, upper and lower elastic modulus and a variety of test curve.
