A pumping station powered by Delta CP2000 frequency drives is delivering environment friendly irrigation to a dairy farm in South Africa in an area experiencing irregular and ever lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and make certain that the water brought to the floor is transferred on to the upper tank.
The dairy farm needed a pump system to access floor water from wells and ensure a reliable and cost-effective water provide. The farm’s owner commissioned an acceptable 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 merchandise from Delta.
The planned irrigation system comprised two reservoirs at totally different heights, to be full of water by a total of six underground well pumps in a single day, when the power costs were low. A transport pump is used to switch water from the lower reservoir to the upper one. The top difference permits the sprinkler system to be operated utilizing gravity alone in the course of the day, making it notably environment friendly. The livestock and the dairy can even take their water provide from this irrigation system. The key requirements of the challenge have been price efficiency and low energy consumption.
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 upper tank. pressure gauge nuova fima ราคา with suggestions that allows the water level in the tanks and boreholes to be monitored and corrected. This is completed by alternating between the completely different pumps and continually monitoring the flow. If the borehole level falls beneath a minimal predetermined by the person, 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 keep the water stage above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water level in the high reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to display all the processes in the system and show system data and warning indicators on a 7 or 15-in contact screen. In-house software program additionally allows the time configuration and power costs to be monitored remotely. Users can even monitor the complete process by way of the DOP-100 VNC server.
The system is now working with none points and supplies each livestock and crops with enough water, even during times of low rainfall.
