First of all, you should see what caused the vibration, the installation of the machine is stable. If no problem, that is the problem of oil. Then you need to do the following:
1, try to drain the main body of the cylinder air.
2, regular oil and cleaning force measuring part of the gear rod, gear, pointer, wire wheel.
3, the oil pump plunger does not work or seven sets of oil distribution valve gap, will make the paper tensile test machine vibration phenomenon.
If the use of plastic tensile testing machine to do the experiment when the vibration situation how to solve? In the face of the vibration situation do not panic, but don't ignore it, because this will affect the final results, so after understanding vibration, according to the above description of the Haida small step test, and then find out the crux of the problem.
