With the continuous progress of society, there is a demand for impact testing machines in all major industries, and it is very important for the staff to understand all aspects of the testing machine's functions! For example, there are failures and errors in the working process of the testing machine, and there are also reasons for these conditions. This article introduces some problems that may occur during the use of the impact testing machine. There are mainly the following five points:
1. After the sample is broken, the pendulum quickly falls back, causing an impact;
2. When doing a tensile test, the sample fracture is always broken on both sides;
3. The hammer return is not normal, sometimes fast and sometimes slow. The passive needle cannot stop at any position well, and it does not overlap with the main needle;
4. The sensitivity of the dial pointer is poor, the position of the pendulum is abnormal, and the pendulum rod of the impact testing machine is not aligned with the vertical mark;
5. When loading, the oil system leaks severely or the oil pipe ruptures.
