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 lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make certain that the water brought to the floor is transferred on to the upper tank.
The dairy farm wanted a pump system to access ground water from wells and guarantee a dependable and cost-effective water supply. pressure gauge หน้าปัด 2 นิ้ว ’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 several automation products from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be crammed with water by a total of six underground nicely 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 top difference permits the sprinkler system to be operated using gravity alone during the day, making it particularly environment friendly. The cattle and the dairy also can take their water supply from this irrigation system. The key necessities of the venture were price effectivity and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water dropped at the surface is transferred on to the higher tank. The CP fashions feature a PID controller with suggestions that enables the water level in the tanks and boreholes to be monitored and corrected. This is done by alternating between the totally different pumps and continually monitoring the flow. If the borehole level falls under a minimal predetermined by the consumer, the PLC control switches to the following the borehole and prevents the pumps from being broken.
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 displays the water stage in the prime reservoir and the animal watering stations, whereas a further DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to display all of the processes within the system and show system information and warning indicators on a 7 or 15-in touch display. In-house software program also permits the time configuration and power costs to be monitored remotely. Users also can monitor the complete course of by way of the DOP-100 VNC server.
The system is now working without any issues and supplies each livestock and crops with adequate water, even during times of low rainfall.
