Hydraulic presses are divided into two categories according to the types of liquids that transmit pressure. There are two categories: hydraulic presses and hydraulic presses. The total pressure generated by hydraulic presses is relatively large and is often used in forging and stamping. Hydraulic press is a machine that uses liquid as the working medium to transfer energy to realize various processes. In addition to forging and forming, it can also be used for correction, pressing, packing, pressing block and pressing plate, etc.
Only by knowing the energy-saving principle of the hydraulic press can energy-saving work be carried out. First, the hydraulic press uses a quantitative pump to supply oil, and the excess oil is returned to the oil tank through a proportional valve. The oil supply and motor speed in this process are unchanged, but the requirements for speed and pressure are different. There is at least a lot of waste in actual operation. By observing the proportional pressure and flow signals of the numerical control system, to adjust the flow regulation required by the various working processes of the hydraulic press, to meet the needs of the system, to reduce the speed of the motor when it is not operating, and to improve the energy-saving space.

由于液压机系统输出功率变化大，在进行不同工序时对流量和压力要求都不一样，就要依靠流量阀和压力阀来调节所需要的流量和压力，但是定量泵没有调节功能，在油温升高时能量就浪费掉了，同时也增加了各个阀门的磨损，油温高噪声大等现象，就会缩短400吨四柱液压机整体的使用时间。
The design capacity of the hydraulic motor is higher than the actual, which also causes the waste of electricity. Therefore, I suggest that you use the frequency conversion energy-saving motor as much as possible to improve the design and reduce waste, protect the motor and extend the service life of the hydraulic machine.GEO-CANARY-86EA1707
