The reason for the expansion of the hydraulic cylinder of the single-column hydraulic press

1. Due to the large load or high speed of the machine, when the machine suddenly stops in an instant, the pressure value in the working chamber will increase immediately, even several times higher than the maximum working pressure, causing the cylinder bore to expand. It may also be caused by the failure of the buffer device in the equipment, so that the running piston cannot decelerate and suddenly hits the cylinder head and may rebound, causing instantaneous overpressure in the working chamber.

2. It may be that the material of the cylinder barrel is inferior or the structural design of the cylinder body is unreasonable, which reduces the yield point and safety factor. Even if it is used for a period of time under normal conditions, the cylinder diameter will inevitably expand. In addition, if the strength and rigidity of the hydraulic cylinder itself are not strong, it will also become the main reason for the expansion of the hydraulic cylinder.
