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 be positive that the water delivered to the surface is transferred on to the upper tank.
The dairy farm wanted a pump system to access floor water from wells and guarantee a reliable and cost-effective water provide. The farm’s proprietor commissioned a suitable system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session 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 total of six underground nicely pumps in a single day, when the power costs have been low. A transport pump is used to switch water from the lower reservoir to the upper one. เกจวัดแรงดันน้ําไทวัสดุ permits the sprinkler system to be operated using gravity alone during the day, making it particularly efficient. The livestock and the dairy also can take their water supply from this irrigation system. The key necessities of the venture were value efficiency and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and be positive that the water delivered to the surface is transferred on to the higher tank. The CP models feature a PID controller with suggestions that enables the water stage within the tanks and boreholes to be monitored and corrected. This is finished by alternating between the completely different pumps and regularly monitoring the circulate. If the borehole stage falls under a minimum predetermined by the consumer, the PLC control switches to the subsequent 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 maintain the water degree above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water degree within the top reservoir and the animal watering stations, while 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 present system info and warning indicators on a 7 or 15-in contact display screen. In-house software program additionally permits the time configuration and power costs to be monitored remotely. Users can even monitor the entire process by way of the DOP-100 VNC server.
The system is now working without any issues and supplies both livestock and crops with adequate water, even during periods of low rainfall.
