WEG variable speed drives (VSDs) offer the agricultural sector the ability to reduce the operating cost on automated water collection systems with a reduction in motor energy consumption when the motor speed is reduced. In addition, they allow the monitoring of all functionalities of a pumping operation, including special functions that not only save operating costs, but optimise, control and protect the entire irrigation system. Just as significant is the ability to send commands automatically to the electric motor, thereby facilitating optimum control of the pumping installation. This allows greater effectiveness when irrigating.
The WEG CFW 700 frequency inverter provides accurate speed variation for the electric motor, ensuring it operates according to the irrigation system pressure needs, and with the necessary field telemetry it can also take different land inclinations into account. Another important benefit is the ability to detect low pressure indicating leakage in a pipeline.
Where water is being pumped from a river to the dam for further irrigation, use of the WEG VSD will allow optimum control of the water level. It will prevent overflow situations, and dry pumping can be set up without the addition of flow sensors. The VSD can also be used to facilitate sleep and wake modes in the pump operation. This facilitates significant cost savings as pumping can then be done on a demand driven basis only.
