เกจวัดแรงดันpressuregauge 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 delivered to the floor is transferred on to the upper tank.
The dairy farm wanted a pump system to entry floor water from wells and guarantee a dependable and cost-effective water supply. The farm’s proprietor commissioned an acceptable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session course of, Pienaar Elektries opted for several automation merchandise from Delta.
The deliberate irrigation system comprised two reservoirs at different heights, to be filled with water by a complete of six underground nicely pumps in a single day, when the power prices 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 using gravity alone through the day, making it particularly environment friendly. The cattle and the dairy also can take their water supply from this irrigation system. The key requirements of the venture have been price effectivity and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make certain that the water delivered to the floor is transferred on to the upper tank. The CP fashions feature a PID controller with feedback that allows the water level within the tanks and boreholes to be monitored and corrected. This is done by alternating between the different pumps and regularly monitoring the move. If the borehole stage falls beneath a minimal predetermined by the user, the PLC management switches to the next the borehole and prevents the pumps from being damaged.
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 value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water degree in the high reservoir and the animal watering stations, while an extra DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 collection are used to show all the processes in the system and present system data and warning indicators on a 7 or 15-in contact screen. In-house software also permits the time configuration and vitality costs to be monitored remotely. Users can even monitor the entire course of via the DOP-100 VNC server.
The system is now working with none issues and provides each livestock and crops with sufficient water, even in periods of low rainfall.
