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 properly pumps and ensure that the water brought to the floor is transferred on to the upper tank.
The dairy farm needed a pump system to entry ground water from wells and ensure a reliable and cost-effective water provide. The farm’s proprietor commissioned an appropriate 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 several automation products from Delta.
The planned irrigation system comprised two reservoirs at completely different heights, to be filled with water by a total of six underground properly pumps in a single day, when the energy prices had been low. A transport pump is used to transfer water from the decrease reservoir to the upper one. The height difference allows the sprinkler system to be operated using gravity alone through the day, making it significantly efficient. The farm animals and the dairy can also take their water provide from this irrigation system. The key necessities of the venture had been price efficiency and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and ensure that the water brought to the floor is transferred on to the higher tank. The CP fashions characteristic a PID controller with feedback that enables the water stage in the tanks and boreholes to be monitored and corrected. This is done by alternating between the different pumps and regularly monitoring the circulate. If the borehole level falls beneath a minimal predetermined by the person, the PLC control switches to the following the borehole and prevents the pumps from being broken.
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 value. pressure gauge digital ราคา regulate the motors. One DVP12SE PLC monitors the water level in the top reservoir and the animal watering stations, whereas an additional DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 series are used to display all the processes within the system and show system data and warning indicators on a 7 or 15-in touch display screen. In-house software additionally allows the time configuration and energy prices to be monitored remotely. Users can also monitor the whole process via the DOP-100 VNC server.
The system is now working without any issues and supplies each livestock and crops with adequate water, even in periods of low rainfall.
