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 area experiencing irregular and ever reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and be certain that the water delivered to the floor is transferred on to the upper tank.
The dairy farm needed a pump system to entry ground water from wells and guarantee a dependable and cost-effective water provide. The farm’s proprietor commissioned an appropriate system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session process, Pienaar Elektries opted for a number of automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at totally different heights, to be crammed with water by a complete of six underground properly pumps overnight, when the power prices have been low. A transport pump is used to switch water from the decrease reservoir to the higher one. The height distinction permits the sprinkler system to be operated using gravity alone in the course of the day, making it notably efficient. The farm animals and the dairy can also take their water provide from this irrigation system. The key requirements of the challenge had been price effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and be positive that the water brought to the floor is transferred on to the upper tank. จำหน่ายเกจวัดแรงดัน with feedback that allows the water degree in the tanks and boreholes to be monitored and corrected. This is finished by alternating between the completely different pumps and continually monitoring the flow. If the borehole level falls under a minimal predetermined by the user, the PLC management switches to the subsequent the borehole and prevents the pumps from being broken.
The system has various Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water stage above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water degree in the high reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to display all of the processes within the system and present system data and warning indicators on a 7 or 15-in contact display screen. In-house software program also allows the time configuration and vitality prices to be monitored remotely. Users can also monitor the whole course of by way of the DOP-100 VNC server.
The system is now working with none points and provides both livestock and crops with sufficient water, even during periods of low rainfall.
