Reduce cost and increase energy usage efficiency are the two important factors to improve our competitiveness. The best way to save energy for old machines is to install an inverter controlling system so there is no need to modify the electrical circuit and hydraulic system. By only installing an inverter controlling system to control the motor rotation speed can save energy up to 40%.

Since the inverter controlling system changes frequency to convert motor rotation speed, the motor rotation speed and flow outlet are both reduced during cooling time or low speed operation. Unlike the fixed rotation speed motor and fixed pump control, the pump still outputs permanent oil flow during cooling time or low speed operation, which wastes a lot of energy. Also, since the motor rotation speed reduces for the inverter controlling system, the pump outlet is reduced that lower the oil temperature and minimized about 40% of cooling water usage, which extends oil seal life and increase stability.

However, the inverter controlling system installation on old and new machines must be differentiated. For new machine, using inverter controlling motor with select special pump is a must, while the motor and pump are not able to be replaced for old machine. Therefore, old machines have limited energy saving result.
Due to the inverter controlling unit motor heating needs to be cooling well during low speed, new machine must use inverter motor with compulsory cooling fan and increase the coil isolator grade to prevent motor burn up. For old machine with inverter controlling unit, the motor low speed needs to run between 300-400 RPM and make sure to cool the heat well to prevent defective.

For pump type, the vane pump rotation lacks for centrifugal force during low speed, which will cause internal leakage and unstable pressure output and not suitable for the inverter controlling system. As for the gear pump type, we must select specific pump model to prevent defective due to not enough pump lubrication.

Since the inverter controlling system constantly change speed, the coupling connection for pump and motor is different from others and must be caution to prevent damage. The selection of inverter controlling system and disturb protecting is even more important. Because the inverter controlling system is not suitable to be overloaded and the heat exchange cooling must be well, we usually choose one level above for the system. For example, if the exchange motor is 25HP, then we choose 30 HP for the inverter controlling system.

Moreover, the inverter controlling system must come with an electric resistant unit to block frequency disturbance and must separate the alternator current wire and signal wire.
