High efficiency, Energy-saving and high precise proportional
pressure and flow variable displacement pump system make the out of
the hydraulic system matching the required power for entire machine
operation without loss of high pressure throttle and overflow
energy. As comparedwith constant displacement pump, t saves power
by 30%~60%.A motor with same power may be fitted with an oil pump
of bigger displacement and thus accelerates the speed of
machine.Besides, the low oil temperature will prolong the service
life of sealing elements.
Buffer device is used in every mold opening and clamping oil way to
ensure steady mold opening and clamping operation without any
impact.Besides, differential mold clamping operation is fitted to
ensure high production efficiency.
High Energy saving
Under the ideal working state, Power consumption is 40% less than
that of variable displacement pump and 70% less than that of fixed
displacement pump, save the cost effectively.
High precision
Precise control of low pressure & low flow, repeating precision is
less than 0.5%. Weight error of the products is 0.4%~0.7%, with
semi-close loop system nearly.
Fast response
With steady capability, servo gearshift dynamical control system
has equipped with pressure feedback device with high precision and
sensitivity, which forms close-loop precision control, cycle time
effectively shortened and improving production efficiency.
Oil temperature rise slowly
The system can restrain arising of oil temperature, so smaller oil
cooling system can be used in the machine.
PQ control
Control pressure and flow simply by inputting simulated voltage of
pressure & flow into the computer.
Low noise
Different from ordinary fixed pump injection molding machine, servo
power-saving injection molding machine is working only when
necessary. And working noise is less than LOG-A8 series, will be
much quieter for your working area.
