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 ensure that the water dropped at the floor is transferred on to the higher tank.
The dairy farm needed a pump system to access floor water from wells and ensure a dependable and cost-effective water supply. The farm’s proprietor commissioned an appropriate system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation course of, Pienaar Elektries opted for several automation products from Delta.
The deliberate irrigation system comprised two reservoirs at totally different heights, to be crammed with water by a complete of six underground well pumps overnight, when the vitality prices have been low. A transport pump is used to switch water from the decrease reservoir to the upper one. The top difference allows the sprinkler system to be operated utilizing gravity alone through the day, making it notably environment friendly. The livestock and the dairy can also take their water provide from this irrigation system. pressure gauge หน้าปัด 2 นิ้ว of the project had been value effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and ensure that the water brought to the surface is transferred on to the upper tank. The CP models characteristic a PID controller with feedback that permits the water stage within the tanks and boreholes to be monitored and corrected. This is finished by alternating between the totally different pumps and frequently monitoring the circulate. If the borehole degree 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 collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep 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 an extra DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 series are used to display all the processes in the system and present system info and warning indicators on a 7 or 15-in touch display screen. In-house software also permits the time configuration and vitality costs to be monitored remotely. Users also can monitor the entire course of through 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.
