Abstract
The present technology includes a hydraulic die-casting machine with electric motor actuated by an inverter, which provides an energy saving evaluation system with respect to a die-casting machine without inverter. The hydraulic die-casting machine includes an injection assembly provided with an injection piston for pressurizing case metal poured into a die and a hydraulic circuit for actuating the injection piston, a hydraulic pump for feeding the hydraulic circuit through a delivery line, an electric motor for actuating the hydraulic pump and an inverter for actuating the electric motor, and an evaluation system for evaluation of the energy savings provided by the present tehcnology.
Claims13
A method for evaluating energy savings of a die-casting machine with an inverter compared to a chosen die-casting machine model having an electric motor without inverter when performing a particular processing operation, the method comprising:
- receiving the chosen die-casting machine model having an electric motor without inverter;
- receiving a pump delivery pressure over a time interval detected by a delivery pressure sensor;
- receiving energy consumption of the electric motor operatively connected to the inverter of the die-casting machine during the time interval detected by a consumption detection device;
- obtaining the absorbed power of a predefined electric motor without an inverter corresponding to the chosen die-casting machine model from a storage device of the die-casting machine with the inverter;
- and
- calculating an estimated energy consumption over the time interval from the delivery pressure and the absorbed power of the chosen die-casting machine model having the predefined electric motor without inverter by a processing device operatively connected to the storage device;
- and
- sending energy consumption of the die-casting machine with the inverter compared to the chosen die-casting machine model having the predefined electric motor without inverter to a display device operatively connected to the processing device.
