The cause of hydraulic cylinder expansion of single column hydraulic press

1 because the machine load or speed is high because when suddenly stop in transient time, cavity pressure value will immediately increase, even more than the high pressure several times, so that the cylinder diameter swell.
2 may be caused by the failure of the buffer device, the operation of the piston is not slow down and suddenly hit the head and may bounce, caused by cavity instantaneous overpressure.
3 may be a cylinder or cylinder inferior material unreasonable design, making the yield point and safety coefficient decreases, even if it is used for a period of time under normal circumstances would bore swell.
4 if the strength and stiffness of the hydraulic cylinder is not strong, it will become the main cause of hydraulic cylinder expansion.
