Only by mastering the basic principle of environmental protection and energy saving of powder forming hydraulic press can we do environmental protection and energy saving work. At first, the powder forming hydraulic press selects the oil provided by the fixed pump, and the excess oil returns to the diesel oil tank according to the proportional solenoid valve. In the whole process, the supplied oil and motor speed will not change, but the speed and working pressure are different, and there is at least a large amount of consumption during operation. According to the frequency conversion and energy saving, investigate the proportion of working pressure and total flow data signal of the NC machine tool management system, adjust the total flow regulation of each work process of the powder forming hydraulic press, so as to meet the needs of the management system. When the management system is not running, reduce the speed of the motor and improve the indoor space of environmental protection and energy saving.

Because the power of the management system of powder forming hydraulic press has changed greatly, the need for total flow and working pressure is different in the whole process of different processing technology. We must rely on the flow valve and pressure valve to adjust the necessary flow and working pressure, but the fixed pump has no maintenance effect, and the temperature will rise. A lot of time is wasting electric energy. The damage of various valve bodies, high oil consumption and high noise will reduce the overall application time of powder forming hydraulic press. The overall planning volume of the hydraulic press motor is higher than the specific overall planning volume, which will also produce waste. Therefore, it is considered that the frequency conversion energy-saving motor should be used as far as possible to improve the overall planning, so as to reduce waste, maintain the motor and broaden the application service life of the powder forming hydraulic press.
