User Manual of SY6000-Z series Principle of energy-saving
Chapter 1 Principle of energy saving
Power consumption of moulding injection machine
mainly in the following sections:
①
Power consumption of hydraulic pump system;
②
Power consumption of heaters;
③
Power consumption of circulating cooling water pump
Electricity consumption of hydraulic pump accounts for
80% energy consumption of the injection molding machine, so
reducing the power consumption is the key to save energy for
molding injection machine.
The pressure and flow are changing when molding
injection machine is in matching mould, cross locking,
injection, material storing, cooling and other stages.
When oil need of the injection molding machine changes,
the relief valve in pump outlet will adjust pressure and flow of
the load, while the output motor power is the same, thus results
in waste of energy.
According to requirements of pressure and speed at the
current work status of moulding injection machine, such as
stages of mold, lock cross, shooting rubber, material storage
and cooling, SY6000-Z series cabinet can adjust automatically
the pump speed the fuel supply to make actual fuel supply be
consistent with actual load flow at any working stage.
Thus it eliminates overflowing of hydraulic oil, reduces
pump output, and saves electricity consumption of pump motor,
so as to achieve the best energy-saving state of moulding
injection machine.
