使用过四柱液压机的人都知道，因为液压机是重工机械所以它的功率是相当的大，又是属于精密设备，所以它的功率一般都是设定好的一个恒定参数的，这样它才可以更稳定的进行工作。然事不例外总有一些小意外的发生，在工作过程中也会发生液压系统的功率损失，功率损失是会浪费公司的资源而且对机械本身也有一定的损伤，那么我们发现这种问题，应该如何降低四柱液压机液压系统功率损失呢?
The answer is to focus on the pump. As the "power source" of hydraulic machinery, the pump plays an important role in the whole operation process of the four-column hydraulic press. The actuators inside the hydraulic press are also prone to a lot of problems during operation. For example, sometimes the hydraulic system requires large flow and low pressure environment, and sometimes requires relatively small flow and high pressure environment.
Therefore, when we choose the pump, it is appropriate to choose a variable pump with a pressure limiting type. This variable pump can be accompanied by the hydraulic machine actuator flow demand and make a corresponding change.
More specifically, when the pressure required by the four-column hydraulic system is gradually reduced, the variable pump will adjust the flow accordingly according to the actual situation to adapt to the rapid switching of the actuator inside the hydraulic press; and when the pressure required by the hydraulic system rises instantaneously, the variable pump can reduce the flow accordingly to meet the operational requirements of the actuator. In summary, the variable pump by adjusting the parameters to allow the actuator to work properly at the same time, but also a reasonable control of the hydraulic system in the operation of the power consumption, to achieve the effect of killing two birds with one stone.
