Delta delivers efficient irrigation to South African farmers

เกจวัดแรงดันน้ำไทวัสดุ 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 lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and make positive 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 appropriate system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation process, Pienaar Elektries opted for a number of automation products from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be crammed with water by a complete of six underground well pumps overnight, when the vitality prices had been low. A transport pump is used to transfer water from the lower reservoir to the higher one. The top distinction permits the sprinkler system to be operated using gravity alone in the course of the day, making it notably efficient. The livestock and the dairy can also take their water provide from this irrigation system. The key necessities of the project were cost efficiency and low energy consumption.
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 upper tank. The CP models characteristic 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 totally different pumps and frequently monitoring the circulate. If the borehole stage falls beneath a minimal predetermined by the consumer, the PLC control switches to the next the borehole and prevents the pumps from being damaged.
The system has varied Delta DVP series 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 level within the high reservoir and the animal watering stations, whereas a further 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 in the system and present system information and warning indicators on a 7 or 15-in contact screen. In-house software program additionally permits the time configuration and energy prices to be monitored remotely. Users can also monitor the entire process through the DOP-100 VNC server.
The system is now working with none points and supplies each livestock and crops with sufficient water, even during times of low rainfall.
