Delta delivers efficient irrigation to South African farmers

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 lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make positive that the water delivered to the floor is transferred on to the higher tank.
The dairy farm wanted a pump system to entry ground water from wells and guarantee a dependable and cost-effective water supply. The farm’s owner 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 several automation merchandise from Delta.
The deliberate irrigation system comprised two reservoirs at totally different heights, to be crammed with water by a complete of six underground well pumps in a single day, when the power prices had been low. A transport pump is used to transfer water from the lower reservoir to the higher one. The peak distinction allows the sprinkler system to be operated using gravity alone in the course of the day, making it significantly environment friendly. The farm animals and the dairy also can take their water supply from this irrigation system. เกจวัดแรงดันsumo of the project were cost efficiency and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make certain that the water dropped at the surface is transferred on to the upper tank. The CP fashions feature a PID controller with feedback that allows the water stage within the tanks and boreholes to be monitored and corrected. This is finished by alternating between the different pumps and frequently monitoring the move. If the borehole degree falls under a minimum predetermined by the consumer, the PLC management switches to the subsequent the borehole and prevents the pumps from being damaged.
The system has numerous Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water level above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens 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 show all of the processes within the system and show system info and warning indicators on a 7 or 15-in contact display. In-house software program also allows the time configuration and energy prices to be monitored remotely. Users can even monitor the whole course of by way of the DOP-100 VNC server.
The system is now working with none issues and supplies both livestock and crops with sufficient water, even in periods of low rainfall.
