A pumping station powered by Delta CP2000 frequency drives is delivering efficient irrigation to a dairy farm in South Africa in an area experiencing irregular and ever reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and make positive that the water delivered to the surface is transferred on to the upper tank.
The dairy farm wanted a pump system to entry floor water from wells and ensure a dependable and cost-effective water provide. The farm’s owner commissioned a suitable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following เกจวัดแรงดันภาษาอังกฤษ -depth planning and session process, Pienaar Elektries opted for a quantity of automation products from Delta.
The planned irrigation system comprised two reservoirs at different heights, to be full of water by a total of six underground nicely pumps in a single day, when the power prices were low. A transport pump is used to transfer water from the lower reservoir to the upper one. The peak distinction allows the sprinkler system to be operated utilizing gravity alone through the day, making it particularly environment friendly. The livestock and the dairy can also take their water supply from this irrigation system. The key necessities of the project have been price effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and be positive that the water dropped at the surface is transferred on to the higher tank. The CP fashions feature a PID controller with suggestions that allows the water stage in the tanks and boreholes to be monitored and corrected. This is done by alternating between the different pumps and frequently monitoring the circulate. If the borehole degree falls below a minimal predetermined by the person, the PLC management 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 screens the water degree within the prime reservoir and the animal watering stations, while a further DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 collection are used to show all of the processes within the system and show system information and warning indicators on a 7 or 15-in touch display. In-house software additionally allows the time configuration and energy prices 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 points and provides both livestock and crops with sufficient water, even in periods of low rainfall.
