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 lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water dropped at the surface is transferred on to the higher tank.
The dairy farm needed a pump system to access ground water from wells and ensure a dependable and cost-effective water provide. The farm’s proprietor commissioned an appropriate system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation process, Pienaar Elektries opted for several automation merchandise 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 in a single day, when the vitality prices have been low. A transport pump is used to switch water from the lower reservoir to the upper one. The top difference permits the sprinkler system to be operated using gravity alone in the course of the day, making it notably environment friendly. The livestock and the dairy can even take their water provide from this irrigation system. The key necessities of the venture have been value efficiency and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make sure that the water delivered to the surface is transferred on to the upper tank. The CP models feature a PID controller with feedback that allows the water level within the tanks and boreholes to be monitored and corrected. differential pressure gauge ราคา is done by alternating between the different pumps and continually monitoring the flow. If the borehole level falls beneath a minimum predetermined by the person, the PLC management switches to the next the borehole and prevents the pumps from being damaged.
The system has various Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water stage above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water level within the prime reservoir and the animal watering stations, while a further DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to show all of the processes within the system and present system info and warning indicators on a 7 or 15-in touch display screen. In-house software program additionally permits the time configuration and power costs to be monitored remotely. Users can also monitor the whole course of by way of the DOP-100 VNC server.
The system is now working with none points and supplies both livestock and crops with adequate water, even in periods of low rainfall.
