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 reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and be sure that the water delivered to the surface is transferred on to the higher tank.
The dairy farm wanted a pump system to access floor water from wells and guarantee a dependable and cost-effective water supply. The farm’s owner commissioned an appropriate 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 quantity of automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at completely different heights, to be full of water by a complete of six underground well pumps overnight, when the vitality prices had been low. A transport pump is used to transfer water from the lower reservoir to the upper one. The top distinction allows the sprinkler system to be operated using gravity alone through the day, making it notably environment friendly. The farm animals and the dairy can even take their water provide from this irrigation system. The key requirements of the challenge were price efficiency and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and make positive that the water delivered to the floor is transferred on to the higher tank. The CP models feature a PID controller with feedback that permits the water stage within the tanks and boreholes to be monitored and corrected. เกจวัดแรงดันแก๊สอาร์กอน is completed by alternating between the totally different pumps and regularly monitoring the flow. If the borehole level falls under a minimum predetermined by the user, the PLC control switches to the subsequent the borehole and prevents the pumps from being damaged.
The system has various Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water stage above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water stage in the top reservoir and the animal watering stations, whereas a further DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 series are used to show all of the processes in the system and show system data and warning indicators on a 7 or 15-in contact display. In-house software program additionally permits the time configuration and vitality prices to be monitored remotely. Users also can 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 sufficient water, even during times of low rainfall.
