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 make sure that the water brought to the surface is transferred on to the upper tank.
The dairy farm needed a pump system to entry ground water from wells and guarantee a reliable and cost-effective water supply. The farm’s owner commissioned an acceptable 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 a number of automation products from Delta.
The deliberate irrigation system comprised two reservoirs at totally different heights, to be full of 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. เกจวัดแรงดันsumo permits the sprinkler system to be operated using gravity alone in the course of the day, making it significantly environment friendly. The livestock and the dairy can also take their water provide from this irrigation system. The key necessities of the project have been value effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and ensure that the water brought to the floor is transferred on to the higher tank. The CP models function a PID controller with feedback that allows the water level in the tanks and boreholes to be monitored and corrected. This is completed by alternating between the completely different pumps and continually monitoring the circulate. If the borehole level falls under a minimum predetermined by the person, the PLC control switches to the following the borehole and prevents the pumps from being damaged.
The system has numerous Delta DVP series programmable logic controllers (PLCs). ราคาเกจวัดแรงดันลม in boreholes and maintain the water level above the predetermined value. 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 installation. Two human-machine interfaces (HMI) from the DOP-100 collection are used to display all of the processes in the system and present system data and warning indicators on a 7 or 15-in touch display. In-house software program additionally allows the time configuration and power prices to be monitored remotely. Users also can monitor the complete process by way of the DOP-100 VNC server.
The system is now working with none points and supplies both livestock and crops with enough water, even during times of low rainfall.
