Delta delivers environment friendly irrigation to South African farmers

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 reducing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and ensure that the water delivered to the surface is transferred on to the higher tank.
The dairy farm needed a pump system to entry floor water from wells and guarantee a reliable and cost-effective water provide. เกจวัดแรงดัน10bar ’s owner commissioned an acceptable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and consultation course of, Pienaar Elektries opted for several automation merchandise from Delta.
The deliberate irrigation system comprised two reservoirs at different heights, to be filled with water by a complete of six underground properly pumps overnight, when the energy prices were low. A transport pump is used to switch water from the lower reservoir to the upper one. The height difference allows the sprinkler system to be operated using gravity alone in the course of the day, making it particularly environment friendly. The livestock and the dairy can even take their water supply from this irrigation system. The key necessities of the project had been price effectivity and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and make sure that the water delivered to the surface is transferred on to the higher tank. The CP models characteristic a PID controller with feedback that allows the water degree in the tanks and boreholes to be monitored and corrected. This is finished by alternating between the completely different pumps and continually monitoring the circulate. If the borehole degree falls below a minimum predetermined by the person, the PLC control switches to the subsequent the borehole and prevents the pumps from being damaged.
The system has various 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 displays the water degree in the prime reservoir and the animal watering stations, whereas a further DVP controller manages the sprinkler installation. 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 screen. In-house software program also permits the time configuration and energy prices to be monitored remotely. Users also can monitor the entire course of by way of the DOP-100 VNC server.
The system is now working without any points and provides both livestock and crops with enough water, even in periods of low rainfall.
