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 decreasing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make certain that the water brought to the surface is transferred on to the higher tank.
The dairy farm needed a pump system to access ground water from wells and guarantee a dependable and cost-effective water provide. The farm’s owner commissioned an acceptable system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation process, Pienaar Elektries opted for several automation merchandise from Delta.
The deliberate irrigation system comprised two reservoirs at completely different heights, to be full of water by a total of six underground nicely pumps overnight, when the power prices have been low. A transport pump is used to transfer water from the lower reservoir to the upper one. pressure gauge หน้าปัด 2 นิ้ว allows the sprinkler system to be operated utilizing gravity alone through the day, making it significantly environment friendly. The farm animals and the dairy can also take their water supply from this irrigation system. The key necessities of the challenge had been cost effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and be sure that the water delivered to the floor is transferred on to the upper tank. The CP models feature a PID controller with feedback that permits the water level in the tanks and boreholes to be monitored and corrected. This is completed by alternating between the different pumps and continually monitoring the circulate. If the borehole stage falls under a minimal predetermined by the user, the PLC control switches to the subsequent the borehole and prevents the pumps from being broken.
The system has numerous Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water stage above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water level in the high reservoir and the animal watering stations, while an extra DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to show all the processes within 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 vitality costs to be monitored remotely. Users can also monitor the whole course of through the DOP-100 VNC server.
The system is now working with none points and provides each livestock and crops with enough water, even during periods of low rainfall.
