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 nicely pumps and ensure that the water brought to the floor is transferred on to the upper tank.
The dairy farm wanted a pump system to access floor water from wells and guarantee a reliable and cost-effective water supply. 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 session course of, Pienaar Elektries opted for a quantity of automation merchandise from Delta.
The deliberate irrigation system comprised two reservoirs at completely different heights, to be filled with water by a total of six underground nicely pumps overnight, when the energy costs had been low. A transport pump is used to switch water from the decrease reservoir to the higher one. The top distinction allows the sprinkler system to be operated using gravity alone through the day, making it significantly environment friendly. The livestock and the dairy also can take their water provide from this irrigation system. The key requirements of the venture have been price effectivity and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and make positive that the water delivered to the floor is transferred on to the higher tank. The CP models feature a PID controller with feedback that enables the water level in the tanks and boreholes to be monitored and corrected. This is completed by alternating between the totally different pumps and continually monitoring the circulate. If the borehole level falls under a minimal predetermined by the person, the PLC management switches to the following the borehole and prevents the pumps from being damaged.
เกจวัดแรงดันแบบแห้ง has various Delta DVP collection 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 screens the water stage within the prime reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 collection are used to show all the processes in the system and show system information and warning indicators on a 7 or 15-in touch display screen. In-house software additionally permits the time configuration and vitality prices to be monitored remotely. Users can also monitor the whole course of through the DOP-100 VNC server.
The system is now working without any issues and provides both livestock and crops with adequate water, even during periods of low rainfall.
