Usedfour-column hydraulic pressEveryone knows that because the hydraulic press is a heavy machinery, its power is quite large and it belongs to precision equipment, so its power is generally a constant parameter set, so that it can work more stably. However, there are always some small accidents. The power loss of the hydraulic system will also occur in the working process. The power loss will waste the company's resources and cause certain damage to the machinery itself. Then we find this problem. How should we reduce the power loss of the hydraulic system of the four-column hydraulic press?
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.
