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 understand that when operating equipment, it is easy to cause pressure overload of four-column hydraulic press. What is the impact of pressure overload on the four-column hydraulic press and how to solve it?
Normally, the normal pressure of the four-column hydraulic press is 25MPa. In the normal production process, the pressure of hydraulic press shall not exceed 25MPa. Take our long-used four-column hydraulic press as an example. The operating temperature is usually within the range of 30-80 degrees. The oil temperature in the hydraulic system of 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 the system pressure regulating valve on the hydraulic system. The pressure overload of four-column hydraulic press will lead to the rapid increase of equipment pressure, which will lead to the overload of hydraulic pump and motor and affect its service life. The corresponding hydraulic cylinder will also overload, affecting the service life of the hydraulic cylinder. If the quality of hydraulic pipeline is not good, it will also cause tubing burst and oil leakage, causing some failures and damaging equipment. Pressure overload of four-column hydraulic press not only affects the performance of the equipment, but also causes certain accidents. Many large manufacturers will consider the corresponding problems at the beginning of the design, install the corresponding unloading valve. When the pressure rises suddenly, the high pressure hydraulic oil returns to the tank through the unloading valve or stop guard.
Since the pressure overload of a four-column hydraulic press is harmless and enormous, many experienced designers have taken this into account. A discharge valve will be installed in the hydraulic system design. Therefore, in the purchase of four-column hydraulic press, not only to see the price of equipment, but also to see the technical strength of the manufacturer. Especially for the four-column hydraulic press purchased by small companies, not only the quality can not be guaranteed, but also the hydraulic system, not to mention the impact of pressure overload.
