A pumping station powered by Delta CP2000 frequency drives is delivering efficient irrigation to a dairy farm in South Africa in an area experiencing irregular and ever lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and be sure that the water delivered to the floor is transferred on to the upper tank.
The dairy farm wanted a pump system to entry floor water from wells and guarantee a dependable and cost-effective water supply. The farm’s owner commissioned a suitable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation process, Pienaar Elektries opted for a number of automation products from Delta.
The planned 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 lower reservoir to the upper one. The peak distinction allows the sprinkler system to be operated utilizing gravity alone during the day, making it notably efficient. The livestock and the dairy also can take their water provide from this irrigation system. The key necessities of the venture had been value effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and make sure that the water brought to the surface is transferred on to the upper tank. The CP models function a PID controller with suggestions that enables the water stage within the tanks and boreholes to be monitored and corrected. This is completed by alternating between the different pumps and continually monitoring the flow. If Unusual falls beneath a minimum predetermined by the user, the PLC management switches to the following the borehole and prevents the pumps from being damaged.
The system has varied Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water level above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water level within the high reservoir and the animal watering stations, whereas a further DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 series are used to show all of the processes in the system and present system info and warning indicators on a 7 or 15-in contact screen. In-house software additionally allows the time configuration and energy costs to be monitored remotely. Users can even monitor the whole course of via the DOP-100 VNC server.
The system is now working with none points and supplies both livestock and crops with enough water, even during periods of low rainfall.
