How does the hydraulic press save energy?

Hydraulic press according to the type of liquid to transfer pressure, there are two categories of hydraulic press and hydraulic press

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.

Due to the large change in the output power of the hydraulic press system, the flow rate and pressure requirements are different in different processes, so it is necessary to rely on the flow valve and the pressure valve to adjust the required flow rate and pressure. However, the quantitative pump has no adjustment function, and energy is wasted when the oil temperature rises. At the same time, it also increases the wear of various valves, high oil temperature and high noise, etc., which will shorten the overall service time of the 400-ton four-column hydraulic press.

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.
