เกจวัดแรงดันpressuregauge 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 ensure that the water dropped at the floor is transferred on to the higher tank.
The dairy farm wanted a pump system to access ground water from wells and guarantee a reliable 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 session course of, Pienaar Elektries opted for a number of automation merchandise from Delta.
The deliberate irrigation system comprised two reservoirs at completely different heights, to be crammed with water by a total of six underground nicely pumps overnight, when the energy costs had been low. A transport pump is used to switch water from the lower reservoir to the higher one. The peak difference permits the sprinkler system to be operated utilizing gravity alone in the course of the day, making it notably environment friendly. The cattle and the dairy can also take their water supply from this irrigation system. The key requirements of the project were value efficiency and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and be positive that the water delivered to the surface is transferred on to the higher tank. The CP models characteristic a PID controller with suggestions that permits the water degree within the tanks and boreholes to be monitored and corrected. This is done by alternating between the completely different pumps and regularly monitoring the move. If the borehole level falls below a minimal predetermined by the consumer, the PLC management switches to the subsequent the borehole and prevents the pumps from being damaged.
The system has numerous Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water degree above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC monitors the water stage within the top reservoir and the animal watering stations, while an extra DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 series are used to show all of the processes in the system and show system info and warning indicators on a 7 or 15-in contact display screen. In-house software program additionally permits the time configuration and power prices to be monitored remotely. Users also can monitor the whole process through the DOP-100 VNC server.
The system is now working without any points and supplies each livestock and crops with sufficient water, even in periods of low rainfall.
