How the hydraulic press reduces the power loss of the hydraulic system

Anyone who has used a four-column hydraulic press knows that because the hydraulic press is a heavy industry machine, its power is quite large, and it is a precision equipment, so its power is generally set to a constant parameter, so that it can be more Work stably. However, without exception, there are always some small accidents. Power loss of the hydraulic system will also occur during work. Power loss will waste the company’s resources and cause certain damage to the machinery itself. Then we find this kind of problem, we should How to reduce the power loss of the hydraulic system of a four-column hydraulic press?

The answer is that the focus is on the pump. As the "power source" of hydraulic machinery, the pump plays an important role in the entire operation of the four-column hydraulic press. The internal actuators of the hydraulic press are also prone to many problems during operation. For example, sometimes the hydraulic system requires a large flow and low pressure environment, while sometimes it requires a relatively small flow and high pressure environment. Therefore, when we choose a pump, it is most appropriate to choose a variable pump with a pressure-limiting type. This kind of variable pump can make corresponding changes along with the flow demand of the hydraulic machine actuator.

In more detail, when the pressure required by the four-column hydraulic system is gradually reduced, the variable pump will increase the flow accordingly according to the actual situation to adapt to the rapid switching of the actuators inside the hydraulic machine; and when the hydraulic system requires When the pressure rises instantaneously, the variable pump can reduce the flow accordingly to meet the operating requirements of the actuator. In summary, while the variable pump allows the actuator to work normally by adjusting the parameters, it also reasonably regulates the power consumed by the hydraulic system during operation, achieving the effect of killing two birds with one stone.
