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 nicely pumps and make certain that the water delivered to 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 supply. ที่วัดแรงดัน ’s proprietor commissioned a suitable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session process, Pienaar Elektries opted for a number 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 well pumps overnight, when the power prices were low. A transport pump is used to transfer water from the lower reservoir to the upper one. The top difference allows the sprinkler system to be operated utilizing gravity alone through the day, making it particularly environment friendly. The farm animals and the dairy can also take their water supply from this irrigation system. The key necessities of the project had been value efficiency and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and be sure that the water dropped at the floor is transferred on to the higher tank. The CP fashions function a PID controller with suggestions that permits the water degree within the tanks and boreholes to be monitored and corrected. This is completed by alternating between the totally different pumps and continually monitoring the circulate. If the borehole stage falls below a minimum predetermined by the person, the PLC control switches to the subsequent the borehole and prevents the pumps from being broken.
The system has numerous Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water level above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water degree 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 series are used to show all the processes in the system and show system information and warning indicators on a 7 or 15-in contact screen. In-house software additionally permits the time configuration and energy prices to be monitored remotely. Users can even monitor the whole course of via the DOP-100 VNC server.
The system is now working without any issues and supplies each livestock and crops with adequate water, even during periods of low rainfall.
