Jinan Testing Machine: Small fault repair of pendulum impact tester

Jinan Test Machine:Pendulum impact testerGlitch repair
If the pendulum impact tester is used for a long time, some minor faults will occur. Let me explain to you about common faults encountered:
1. During tensile test, the sample fracture is always broken on both sides.
2. The dial pointer has poor sensitivity, the position of the pendulum is abnormal, and the swing rod of the impact tester is not marked vertically.
3. The hammer returns to the position abnormally, sometimes fast and sometimes slow. The passive needle cannot stop well in any position and does not coincide with the main needle.
4. When loading, the oil circuit system will have serious oil leakage or the oil pipe will be broken.
5. After the sample breaks, the pendulum quickly falls back, causing an impact.
Normally, the solution to the failure of the impact tester is:
1. If the jaws are not placed in a straight position when clamping, the jaws should be clamped symmetrically as required.
2. The jaws are of poor quality and damage to the teeth. In addition to affecting the jaws, the sample is slipped during the test, making it difficult to identify the yield point. The jaws should be replaced at this time
