A hydraulic press is a machine that uses liquid as the working medium and is used to transfer energy to achieve various processes. In addition to forging and forming, it can also be used for correction, pressing, packaging, pressing blocks, and pressing plates.
                         
Only by knowing the energy-saving principle of the hydraulic press can we carry out energy-saving work. First, the hydraulic press uses a quantitative pump to supply oil, and the excess oil is returned to the tank through a proportional valve. In this process, the oil supply volume and motor speed remain unchanged, but the requirements for speed and pressure are different. There is at least a lot of waste in actual operations. Frequency conversion is used to save energy. By observing the proportional pressure and flow signals of the CNC system, the flow adjustment required for each working process of the hydraulic press is adjusted to meet the needs of the system. The motor slows down when not operating. , improve energy saving space.
Since the output power of the hydraulic press system changes greatly, the flow and pressure requirements are different when carrying out different processes. It is necessary to rely on the flow valve and the pressure valve to adjust the required flow and pressure. However, the quantitative pump does not have an adjustment function. When the oil temperature rises, When it is high, energy is wasted, and the wear of each valve is increased. High oil temperature and loud noise will shorten the overall use time of the 400 ton four-column hydraulic press.
The designed capacity of the hydraulic press motor is higher than the actual, which also causes a waste of electricity. It is recommended that you try to use variable frequency energy-saving motors, improve the design and reduce waste, protect the motor and extend the service life of the hydraulic press.
