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 lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and make certain that the water dropped at the surface is transferred on to the upper tank.
The dairy farm needed a pump system to access floor water from wells and ensure a reliable and cost-effective water provide. The farm’s proprietor commissioned a suitable system from electrical installation planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session process, Pienaar Elektries opted for a number of automation merchandise from Delta.
ราคาเกจวัดแรงดัน comprised two reservoirs at completely different heights, to be full of water by a total of six underground nicely pumps in a single day, when the energy prices were low. A transport pump is used to transfer water from the decrease reservoir to the higher one. The top difference allows the sprinkler system to be operated utilizing gravity alone through the day, making it notably environment friendly. The cattle and the dairy can even take their water supply from this irrigation system. The key necessities of the venture were value efficiency and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and be certain that the water brought to the surface is transferred on to the higher tank. The CP fashions characteristic a PID controller with feedback that enables the water stage within the tanks and boreholes to be monitored and corrected. This is completed by alternating between the totally different pumps and continually monitoring the circulate. If the borehole stage falls beneath a minimal predetermined by the person, the PLC control switches to the next the borehole and prevents the pumps from being broken.
The system has varied Delta DVP series programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water stage above the predetermined worth. Five DVP16SP PLCs regulate the motors. ราคาเกจวัดแรงดันน้ำ within the top reservoir and the animal watering stations, while an additional 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 present system data and warning indicators on a 7 or 15-in contact display. In-house software also allows the time configuration and power costs to be monitored remotely. Users also can monitor the entire process through the DOP-100 VNC server.
The system is now working with none points and provides both livestock and crops with enough water, even in periods of low rainfall.
