A 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 decreasing rainfall.
เกจไนโตรเจนsumo -energy Delta CP2000 frequency drives drive the six underground properly pumps and make certain that the water brought to the floor is transferred on to the upper tank.
The dairy farm needed a pump system to access floor water from wells and ensure a dependable and cost-effective water provide. The farm’s owner commissioned a suitable system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation process, Pienaar Elektries opted for a number of automation products from Delta.
The deliberate irrigation system comprised two reservoirs at different heights, to be crammed with water by a complete of six underground nicely pumps overnight, when the power costs have been low. A transport pump is used to switch water from the decrease reservoir to the higher one. The peak difference allows the sprinkler system to be operated utilizing gravity alone in the course of the day, making it significantly efficient. The cattle and the dairy also can take their water provide from this irrigation system. The key requirements of the challenge 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 floor is transferred on to the upper tank. The CP models characteristic a PID controller with feedback that permits the water level in the tanks and boreholes to be monitored and corrected. This is finished by alternating between the totally different pumps and regularly monitoring the move. If the borehole stage falls below a minimal predetermined by the user, the PLC management switches to the next the borehole and prevents the pumps from being broken.
The system has various Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water level above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water level within the prime 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 show system info and warning indicators on a 7 or 15-in contact display. In-house software program additionally permits the time configuration and vitality costs to be monitored remotely. Users can also monitor the whole process via the DOP-100 VNC server.
The system is now working with none points and supplies both livestock and crops with sufficient water, even in periods of low rainfall.
