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 decreasing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water delivered to the surface is transferred on to the higher tank.
The dairy farm needed a pump system to entry ground water from wells and guarantee a reliable 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 session process, Pienaar Elektries opted for several automation products from Delta.
The deliberate irrigation system comprised two reservoirs at different heights, to be filled with water by a total of six underground nicely pumps in a single day, when the energy prices had been low. A transport pump is used to switch water from the lower reservoir to the upper one. เกจวัดแรงดัน4นิ้วราคา permits the sprinkler system to be operated using gravity alone through the day, making it particularly efficient. The farm animals and the dairy can also take their water supply from this irrigation system. The key necessities of the challenge have been value effectivity and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and be positive that the water brought to the surface is transferred on to the higher tank. The CP models 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 flow. If the borehole stage falls beneath a minimum predetermined by the consumer, the PLC management switches to the subsequent 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 stage above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water stage within the high reservoir and the animal watering stations, whereas an extra DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 series are used to display all of the processes within the system and present system info and warning indicators on a 7 or 15-in contact display. In-house software additionally permits the time configuration and energy prices to be monitored remotely. Users can even monitor the whole course of via the DOP-100 VNC server.
The system is now working without any points and supplies each livestock and crops with enough water, even during times of low rainfall.
