A pumping station powered by Delta CP2000 frequency drives is delivering efficient irrigation to a dairy farm in South Africa in an space experiencing irregular and ever reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and ensure that the water dropped at the surface is transferred on to the higher tank.
The dairy farm wanted a pump system to entry floor water from wells and ensure a dependable and cost-effective water provide. The farm’s owner commissioned an acceptable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation course of, Pienaar Elektries opted for several automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be crammed with water by a total of six underground nicely pumps overnight, when the vitality prices have been low. A transport pump is used to transfer water from the lower reservoir to the higher one. The height distinction permits the sprinkler system to be operated utilizing gravity alone during the day, making it notably environment friendly. The farm animals and the dairy also can take their water supply from this irrigation system. The key requirements of the project were value efficiency and low vitality consumption.
เกจวัดแรงอัดกระบอกสูบ -energy Delta CP2000 frequency drives drive the six underground well pumps and be sure that the water brought to the surface is transferred on to the upper tank. The CP models function 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 continually monitoring the move. If the borehole level falls below a minimum predetermined by the person, the PLC management switches to the following the borehole and prevents the pumps from being broken.
The system has varied Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water degree above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water level 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 sequence are used to display all of the processes in the system and present system info and warning indicators on a 7 or 15-in contact screen. In-house software also permits the time configuration and power prices to be monitored remotely. Users also can monitor the entire course of via 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.
