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 well pumps and ensure that the water brought to the floor is transferred on to the higher tank.
เกจวัดแรงดันต่ำ needed a pump system to access ground water from wells and guarantee a dependable and cost-effective water provide. The farm’s proprietor 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 a quantity of automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be filled with water by a complete of six underground properly pumps in a single day, when the energy prices were low. A transport pump is used to transfer water from the decrease reservoir to the upper one. The height distinction permits the sprinkler system to be operated utilizing gravity alone in the course of the day, making it notably environment friendly. The farm animals and the dairy can even take their water provide from this irrigation system. The key necessities of the project had been value effectivity and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and be sure that the water dropped at the surface is transferred on to the upper tank. The CP fashions function a PID controller with feedback that allows the water stage in the tanks and boreholes to be monitored and corrected. This is finished by alternating between the completely different pumps and frequently monitoring the move. If the borehole degree falls below a minimal predetermined by the user, the PLC control switches to the following the borehole and prevents the pumps from being damaged.
The system has varied Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water level above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water level in the prime reservoir and the animal watering stations, whereas an additional DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to display all the processes within the system and present system info and warning indicators on a 7 or 15-in contact display. In-house software also allows the time configuration and vitality costs to be monitored remotely. Users can also monitor the whole course of via the DOP-100 VNC server.
The system is now working without any issues and provides both livestock and crops with adequate water, even in periods of low rainfall.
