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 lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and make sure that the water dropped at the surface is transferred on to the upper tank.
The dairy farm wanted a pump system to entry ground water from wells and guarantee a dependable and cost-effective water supply. The farm’s owner commissioned a suitable 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 products from Delta.
The planned irrigation system comprised two reservoirs at completely different heights, to be full of water by a total of six underground well pumps overnight, when the energy prices have been low. เกจ์วัดแรงดัน is used to transfer water from the decrease reservoir to the higher one. The peak difference permits the sprinkler system to be operated utilizing gravity alone in the course of the day, making it particularly environment friendly. The cattle and the dairy can also take their water supply from this irrigation system. The key necessities of the venture have been cost effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water brought to the surface is transferred on to the higher tank. The CP fashions feature a PID controller with suggestions that enables the water degree in the tanks and boreholes to be monitored and corrected. This is finished by alternating between the different pumps and frequently monitoring the circulate. If the borehole level falls under a minimal predetermined by the person, 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 keep the water degree above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water degree in the top reservoir and the animal watering stations, whereas an additional DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 series are used to show all the processes in the system and present system info and warning indicators on a 7 or 15-in touch screen. In-house software also allows the time configuration and vitality costs to be monitored remotely. Users can even monitor the whole 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 enough water, even in periods of low rainfall.
