Equipment application

this equipment is used to measure the resistance of metal materials to impact under dynamic load in order to judge the properties of the material under dynamic load. Using the difference between the potential energy before the impact of the pendulum and the remaining potential energy after the impact is displayed on the dial, to obtain the absorption work of the sample. the maximum impact energy is 300J, and also attached one pendulum of 150J, and the cross section of the sample used is (10 10) mm.

the operation adopts semi-automatic control, easy to operate, high working efficiency. Using the residual energy after the pendulum breaking the sample, it can automatically raise the pendulum, and it can reflect its superiority when continuously performing specimen impact test. It is mainly used in measurement and quality inspection, technical supervision departments, metallurgy and iron and steel, machinery manufacturing, pressure vessels, automobile production, universities, research institutes and other industries.
