Delta delivers efficient irrigation to South African farmers

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 lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make positive that the water brought to the floor is transferred on to the higher tank.
The dairy farm needed a pump system to entry ground water from wells and ensure a reliable 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 course of, Pienaar Elektries opted for a quantity of automation merchandise from Delta.
The deliberate irrigation system comprised two reservoirs at completely different heights, to be crammed with water by a total of six underground properly pumps overnight, when the energy prices were low. A transport pump is used to transfer water from the lower reservoir to the upper one. The peak difference allows the sprinkler system to be operated utilizing gravity alone through the day, making it particularly efficient. The farm animals and the dairy also can take their water supply from this irrigation system. เกจวัดแรงดันลม10bar of the venture have been value efficiency and low vitality consumption.

The CP fashions feature a PID controller with suggestions that enables the water level within the tanks and boreholes to be monitored and corrected. This is finished by alternating between the totally different pumps and regularly monitoring the flow. If the borehole degree falls beneath a minimal predetermined by the user, the PLC control 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 displays the water stage in the top reservoir and the animal watering stations, whereas an additional DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 series are used to show all the processes within the system and present system information and warning indicators on a 7 or 15-in touch display screen. In-house software program additionally permits the time configuration and energy prices to be monitored remotely. Users also can monitor the complete process through the DOP-100 VNC server.
The system is now working with none points and provides both livestock and crops with enough water, even in periods of low rainfall.
