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 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 floor 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 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 products from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be crammed with water by a complete of six underground properly pumps in a single day, when the vitality costs have been low. A transport pump is used to switch water from the lower reservoir to the higher one. เพรสเชอร์เกจดิจิตอล permits the sprinkler system to be operated utilizing gravity alone through the day, making it notably environment friendly. The farm animals and the dairy can also take their water provide from this irrigation system. The key necessities of the venture were cost effectivity and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and ensure that the water delivered to the surface is transferred on to the higher tank. The CP models feature a PID controller with suggestions that permits the water level within the tanks and boreholes to be monitored and corrected. This is done by alternating between the completely different pumps and frequently monitoring the circulate. If the borehole level falls below a minimal predetermined by the user, the PLC management switches to the following the borehole and prevents the pumps from being damaged.
The system has various Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water degree above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water level in the high reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 collection are used to display all of the processes within the system and show system data and warning indicators on a 7 or 15-in contact display. In-house software program additionally permits the time configuration and vitality costs to be monitored remotely. Users also can monitor the whole process by way of the DOP-100 VNC server.
The system is now working with none issues and supplies both livestock and crops with enough water, even in periods of low rainfall.
