Delta delivers efficient 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 reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and make certain that the water brought to the floor is transferred on to the upper tank.
The dairy farm needed a pump system to entry floor water from wells and guarantee a reliable and cost-effective water provide. The farm’s proprietor commissioned an acceptable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following ไดอะแฟรม -depth planning and consultation process, Pienaar Elektries opted for a quantity of automation products from Delta.
ไดอะแฟรม comprised two reservoirs at completely different heights, to be crammed with water by a total of six underground properly pumps overnight, when the energy prices were low. A transport pump is used to transfer water from the decrease reservoir to the higher one. digital pressure gauge allows the sprinkler system to be operated utilizing gravity alone during the day, making it notably efficient. The cattle and the dairy also can take their water supply from this irrigation system. The key requirements of the project had been value efficiency and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and make sure that the water brought to the surface is transferred on to the higher tank. The CP fashions function a PID controller with suggestions that permits the water level in the tanks and boreholes to be monitored and corrected. This is completed by alternating between the totally different pumps and continually monitoring the circulate. If the borehole degree falls beneath a minimum predetermined by the consumer, the PLC control switches to the next the borehole and prevents the pumps from being damaged.
The system has numerous Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water stage above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water level in the top 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 sequence are used to show all of the processes within the system and present system information and warning indicators on a 7 or 15-in touch screen. In-house software program also allows the time configuration and power prices to be monitored remotely. Users also can monitor the complete course of by way of the DOP-100 VNC server.
The system is now working without any points and provides both livestock and crops with sufficient water, even during times of low rainfall.
