four-column hydraulic pressUnder normal circumstances by the host and control system, the following four-column hydraulic press hydraulic cylinder damage causes and treatment methods are analyzed as follows. Overload operation of the cylinder of the four-column hydraulic press is usually due to improper design, production or operation, and premature damage. Therefore, the hydraulic cylinder should be aware of its damage status and reasons.
1. four-column hydraulic press hydraulic cylinder damaged parts mostly in the flange and hydraulic cylinder joint part, followed by the hydraulic cylinder to the bottom of the transition part, a few cracks in the cylinder, but also due to severe cavitation and damage. From the point of view of the use of hydraulic cylinders, they have generally been subjected to a high number of operating loads when damaged.
2. to the damage of the hydraulic cylinder of the four column hydraulic press, the factors that affect the working life of the hydraulic cylinder are various. It is necessary to analyze the specific situation, but summed up the first several aspects: design reasons, structural size reasons: such as flange height is too small or flange diameter is too large, so that the induction should be too high and damaged.
