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 decreasing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and be sure that the water delivered to the surface 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 owner commissioned a suitable system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation course of, Pienaar Elektries opted for a quantity of automation products from Delta.
The planned irrigation system comprised two reservoirs at totally different heights, to be filled with water by a complete of six underground nicely pumps in a single day, when the power costs were low. A transport pump is used to transfer water from the lower reservoir to the higher one. The peak difference allows the sprinkler system to be operated utilizing gravity alone in the course of the day, making it significantly efficient. The livestock and the dairy can even take their water supply from this irrigation system. The key requirements of the challenge were price effectivity and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and be certain that the water dropped at the floor is transferred on to the upper tank. The CP fashions feature a PID controller with suggestions that enables the water level within the tanks and boreholes to be monitored and corrected. This is completed by alternating between the completely different pumps and regularly monitoring the circulate. If เกรดวัดแรงดัน falls beneath a minimal predetermined by the consumer, the PLC management switches to the next the borehole and prevents the pumps from being broken.
The system has numerous Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water level above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water stage within the top reservoir and the animal watering stations, whereas an extra DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 collection are used to display all the processes within the system and present system information and warning indicators on a 7 or 15-in contact display. In-house software also permits the time configuration and energy prices to be monitored remotely. Users can also monitor the entire process via the DOP-100 VNC server.
The system is now working without any issues and supplies both livestock and crops with enough water, even in periods of low rainfall.
