Delta delivers environment friendly irrigation to South African farmers

A pumping station powered by Delta CP2000 frequency drives is delivering environment friendly irrigation to a dairy farm in South Africa in an area experiencing irregular and ever decreasing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water brought to the surface is transferred on to the higher tank.
The dairy farm needed a pump system to access floor water from wells and guarantee a reliable and cost-effective water provide. The farm’s proprietor commissioned an appropriate system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session process, Pienaar Elektries opted for a quantity of automation products from Delta.
The deliberate irrigation system comprised two reservoirs at totally different heights, to be filled with water by a complete of six underground well pumps overnight, when the vitality costs were 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 using gravity alone during the day, making it notably efficient. The livestock and the dairy can also take their water provide from this irrigation system. The key necessities of the project have been price efficiency and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and make sure that the water delivered to the surface is transferred on to the higher tank. The CP models characteristic a PID controller with suggestions that permits the water degree within the tanks and boreholes to be monitored and corrected. This is completed by alternating between the completely different pumps and frequently monitoring the circulate. If the borehole degree falls beneath a minimal predetermined by the consumer, the PLC management switches to the subsequent the borehole and prevents the pumps from being damaged.
The system has various Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water degree above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water level within the top reservoir and the animal watering stations, while a further DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to display all the processes within the system and present system data and warning indicators on a 7 or 15-in touch display. In-house software program additionally allows the time configuration and vitality costs to be monitored remotely. เกจวัดแรงดันไฟฟ้า of via the DOP-100 VNC server.
The system is now working without any issues and provides both livestock and crops with enough water, even in periods of low rainfall.
