Delta delivers environment friendly irrigation to South African farmers

เกจวัดแรงดันราคา 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 well pumps and ensure that the water delivered to the floor is transferred on to the higher tank.
The dairy farm needed a pump system to entry ground water from wells and ensure a reliable and cost-effective water supply. 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 session process, Pienaar Elektries opted for several automation merchandise from Delta.
The deliberate irrigation system comprised two reservoirs at totally different heights, to be full of water by a complete of six underground well pumps in a single day, when the vitality costs have been low. A transport pump is used to transfer water from the lower reservoir to the upper one. The peak distinction permits the sprinkler system to be operated using gravity alone during the day, making it notably environment friendly. The cattle and the dairy also can take their water provide from this irrigation system. The key necessities of the venture have been price efficiency and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and make sure that the water delivered to the floor is transferred on to the higher tank. The CP fashions characteristic a PID controller with suggestions that permits the water stage in the tanks and boreholes to be monitored and corrected. This is completed by alternating between the completely different pumps and continually monitoring the move. If the borehole degree falls beneath a minimal predetermined by the person, the PLC control switches to the following the borehole and prevents the pumps from being damaged.
The system has varied Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water degree above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water stage within the high reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 series are used to show all the processes within the system and present system information and warning indicators on a 7 or 15-in contact display. In-house software program additionally permits the time configuration and power costs to be monitored remotely. Users also can monitor the complete process by way of the DOP-100 VNC server.
The system is now working without any points and supplies each livestock and crops with sufficient water, even during periods of low rainfall.
