Application and Advantage
Some of the key benefits of high-performance vector converters are as follows:
(1)Protective motor
With the development of electric power technology, frequency converters have replaced the previous multi-pump switches and valves to regulate water supply. The initial current can be limited within the rated current range to avoid any impact on the power system.
(2)Prolong motor working life time
VFD can keep motor running at optimal situation.
(3)Save energy
Conclusion
In general, after the installation of a high-performance vector frequency inverter, through advanced PID control, the water treatment plant can improve the process efficiency and obtain significant energy savings and reduce maintenance costs.
