why injection molding machine need use special inverter for injection molding machine?
    The general inverter is the widest application among the inverter and applicability is also the best. But the injection molding machine is need to choose a special injection type inverter, why should the selection of injection molding machine dedicated inverter, what are the differences between it and the general inverter?
    In the working process of the injection molding machine, the required flow rate and pressure are changed. The wildly use of a oil pump of in the injection molding machine is the quantitative pump, oil supply is constant. Quantitative pump to change the pressure and flow, which is adjust by the flow proportional valve and pressure valve, the extra oil flows back to the oil tank through the overflow valve. While this kind of situation will intensify pump and valve, causing the oil temperature rise, and the motor noise.
    Special injection molding machine drive not only save energy but also can reduce the oscillation made by lock mode and reduce the heat, can make the injection molding machine running stable. The injection molding machine injection molding machine has install special type frequency inverter,can not only reduces the impact caused by motor start and stop, also reduces the power pollution, plays the function of environmental protection, but also can raise the work efficiency, saving effect. After the installation of special type injection molding machine with inverter, can reduce the running speed of pump, and ten reduce mechanical wear pump, prolongs the service life of oil pump.
    Injection molding machine using a special injection molding machine drive can better improve the economic efficiency of enterprises, this is also the reason why injection molding machine injection molding machine select the specific frequency converter,not the general inverter.
