Frequency Three Phase Inverter Drives for Water Pumps in Sea Food Farming
A pumps system controls sea water cycle in a sea food farming plant. The water from the sea is filtered via several tanks and at the end to the tank where sea animals live. The pumps become an important part of this system, water flow is controlled anytime.
Application Challenges
Maintain positive pressure in the tanks. Maintain a high quality filtering system at all times. Avoid mechanical resonance in the surrounding equipment. Automatic restart at the power instant off case. Features of P5 series matching sea food farming pumps|

Tips:
A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.
