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 space experiencing irregular and ever reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and be certain that the water delivered to the surface is transferred on to the upper tank.
The dairy farm wanted a pump system to entry floor water from wells and ensure a reliable and cost-effective water supply. The farm’s proprietor 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 different heights, to be crammed with water by a complete of six underground properly pumps overnight, when the vitality prices have been low. A transport pump is used to transfer water from the lower reservoir to the upper one. The height difference permits the sprinkler system to be operated using gravity alone through the day, making it particularly environment friendly. The cattle and the dairy can also take their water provide from this irrigation system. The key requirements of the challenge were cost effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water dropped at the floor is transferred on to the higher tank. The CP models feature a PID controller with suggestions that permits the water level in the tanks and boreholes to be monitored and corrected. This is done by alternating between the totally different pumps and frequently monitoring the circulate. If the borehole stage falls below a minimum predetermined by the consumer, the PLC control 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 level above the predetermined worth. ตัววัดแรงดันน้ำ regulate the motors. One DVP12SE PLC screens 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 collection 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. In-house software program additionally permits the time configuration and energy costs to be monitored remotely. Users can even monitor the complete course of by way of the DOP-100 VNC server.
The system is now working with none issues and supplies each livestock and crops with sufficient water, even during times of low rainfall.
