With respect to prior art, a kind of impact velocity of tubing drop hammer impact testing machine described in the utility model controls dress
Put and have the advantage that
The impact velocity control device of tubing drop hammer impact testing machine of the present invention can set according to different tubing
The normal data of fixed corresponding tubing test, the size of gas flow in information transmitter automatic detection vacuum pipe, and and criterion numeral
According to being compared, then adjust the angle of electrodynamic valve, that is, adjust the falling speed dropped hammer, instead of the debugging behaviour of manual calibration
Make, improve the precision of calibration and the efficiency adjusting, decrease the error rate of experiment, reduce the waste degree of sample, can
Effectively guarantee the error rate of real impact speed and theoretical impact speed.
