Delta delivers efficient irrigation to South African farmers

A pumping station powered by Delta CP2000 frequency drives is delivering efficient irrigation to a dairy farm in South Africa in an space experiencing irregular and ever lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make sure that the water brought to the floor is transferred on to the upper tank.
The dairy farm needed a pump system to access ground water from wells and guarantee a reliable and cost-effective water provide. The farm’s proprietor commissioned an acceptable system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation course of, Pienaar Elektries opted for a number of automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at totally different heights, to be filled with water by a total of six underground nicely pumps in a single day, when the vitality prices had been low. A transport pump is used to transfer water from the decrease reservoir to the higher one. The height distinction allows the sprinkler system to be operated utilizing gravity alone through the day, making it significantly efficient. The cattle and the dairy also can take their water supply from this irrigation system. The key requirements of the project have been cost efficiency and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water delivered to the surface is transferred on to the higher tank. The CP models feature a PID controller with feedback that permits the water stage in the tanks and boreholes to be monitored and corrected. This is done by alternating between the totally different pumps and frequently monitoring the move. If the borehole stage falls under a minimal predetermined by the user, the PLC management switches to the next the borehole and prevents the pumps from being broken.
เกวัดแรงดัน has various Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water stage above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water degree within the prime reservoir and the animal watering stations, while a further DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 collection are used to display all of the processes within the system and present system info and warning indicators on a 7 or 15-in contact display. In-house software program additionally permits the time configuration and power prices to be monitored remotely. Users can even monitor the whole process by way of the DOP-100 VNC server.
The system is now working without any points and supplies both livestock and crops with adequate water, even during times of low rainfall.
