Delta delivers environment friendly irrigation to South African farmers

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 lowering rainfall.
pressure gauge octa -energy Delta CP2000 frequency drives drive the six underground nicely pumps and be sure that the water delivered to the floor is transferred on to the higher tank.
The dairy farm wanted a pump system to entry ground water from wells and guarantee 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 session course of, Pienaar Elektries opted for several automation merchandise from Delta.
The deliberate irrigation system comprised two reservoirs at completely different heights, to be filled with water by a complete of six underground well pumps in a single day, when the vitality prices were low. A transport pump is used to switch water from the decrease reservoir to the higher one. The peak difference permits the sprinkler system to be operated utilizing gravity alone during the day, making it particularly environment friendly. The farm animals and the dairy also can take their water supply from this irrigation system. The key requirements of the challenge were price effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and be certain that the water dropped at the floor is transferred on to the upper tank. The CP fashions feature a PID controller with feedback that enables the water level within the tanks and boreholes to be monitored and corrected. This is finished by alternating between the different pumps and frequently monitoring the move. If the borehole stage falls under a minimum predetermined by the user, the PLC management switches to the following the borehole and prevents the pumps from being damaged.
The system has numerous Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water degree above the predetermined worth. pressure gauge 10 bar regulate the motors. One DVP12SE PLC screens the water stage in the prime reservoir and the animal watering stations, whereas an extra DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to display all the processes within the system and show system info and warning indicators on a 7 or 15-in contact display. In-house software program also allows the time configuration and power costs to be monitored remotely. Users also can monitor the entire process via the DOP-100 VNC server.
เพรสเชอร์เกจ is now working with none points and supplies both livestock and crops with enough water, even during times of low rainfall.
