Detailed installation of hollow strike test of impact test machine

Impact testing machineWhen doing the test, it is mainly to understand whether the energy loss caused by friction during the test is too large or exceeds the specified value. During the air strike test, the energy consumed in various resistances during a swing for the impact sway. The energy loss of pendulum is allowed to be 1.5 Joule for 300 Joule pendulum and 0.75 Joule for 150 Joule pendulum is allowed to be 0.75 Joule. If the specified value exceeds the specified value, check whether the brake belt is friction with the swing shaft during the impact process. If the pointer still does not meet the above requirements after inspection and proper adjustment; then it is necessary to check whether the installation of the test machine is correct, whether the swing shaft is horizontal, and whether the ball bearings at both ends of the swing shaft are clean and flexible until the above requirements are met.

When placing the sample, just put the back of the cut groove facing the blade, place it flat on the two jaw brackets, and then use the sample to find the right plate to make the gap on the sample located exactly in the middle of the span of the jaw. After rectifying (don't make the sample change when taking away the sample) you can perform the impact test.

Notice:When placing samples, the impact swing bracket should be supported first; never place the sample after the impact swing is raised to the reserved position before the impact to prevent the impact swing from falling off due to accidental misfilling.
