เกจวัดความดันpressuregauge 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 properly pumps and be sure that the water brought to the surface is transferred on to the higher tank.
The dairy farm wanted a pump system to access ground water from wells and ensure a dependable and cost-effective water supply. 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 several automation products from Delta.
The planned irrigation system comprised two reservoirs at totally different heights, to be full of water by a complete of six underground properly pumps overnight, when the power costs had been low. A transport pump is used to switch water from the lower reservoir to the higher one. เกจวัดแรงดัน250bar allows the sprinkler system to be operated utilizing gravity alone through the day, making it significantly efficient. The livestock and the dairy also can take their water supply from this irrigation system. The key necessities of the project were price efficiency and low energy consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and make sure that the water dropped at the floor is transferred on to the higher tank. The CP fashions function a PID controller with suggestions that enables the water stage within the tanks and boreholes to be monitored and corrected. This is completed by alternating between the completely different pumps and frequently monitoring the move. If the borehole degree falls below a minimal predetermined by the person, the PLC management switches to the following the borehole and prevents the pumps from being damaged.
The system has varied Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and keep the water level above the predetermined worth. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water level within the high reservoir and the animal watering stations, while an extra DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 sequence are used to show all of the processes within the system and show system info and warning indicators on a 7 or 15-in touch display. In-house software program also allows the time configuration and vitality costs to be monitored remotely. Users can also monitor the whole course of by way of the DOP-100 VNC server.
The system is now working without any issues and supplies each livestock and crops with adequate water, even during periods of low rainfall.
