What is the impact of excessive pressure on a four column hydraulic press?

The system pressure of the four-column hydraulic press is designed to be higher than the actual pressure, which not only increases the service life of the equipment, but also protects the hydraulic components from damage. Many people do not know that it is easy to cause pressure overload on the four-column hydraulic press when operating the equipment. As a hydraulic press manufacturer, today we will introduce the impact of pressure overload on the four-column hydraulic press and how to solve it?

Generally, the normal pressure of a four-column hydraulic press is 25MPa.During normal production, the pressure of the hydraulic press must not exceed 25MPa.Take the 315 three-beam and four-column hydraulic press that we have used for a long time as an example.The operating temperature is usually in the range of 30-80 degrees. The oil temperature in the hydraulic system of the four-column hydraulic press must be controlled within the range of 30-60 degrees. If the oil temperature exceeds this range, it will have many adverse effects on the hydraulic system.When the working pressure of the four-column hydraulic press is greater than 25MPa, we can control the working pressure of the four-column hydraulic press through the electric contact pressure gauge or system pressure regulating valve on the hydraulic system.The pressure overload of the four-column hydraulic press will cause the equipment pressure to rise rapidly, causing the hydraulic pump and motor to overload and affecting their service life.The corres
