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 decreasing rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and be sure that the water dropped at the floor is transferred on to the upper tank.
The dairy farm wanted a pump system to entry floor water from wells and ensure a dependable and cost-effective water supply. The farm’s owner commissioned an appropriate 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 quantity of automation merchandise from Delta.
The planned irrigation system comprised two reservoirs at completely different heights, to be crammed with water by a complete of six underground well pumps in a single day, when the energy prices had been low. A transport pump is used to transfer water from the lower reservoir to the higher one. The top distinction allows the sprinkler system to be operated utilizing gravity alone through the day, making it particularly efficient. The farm animals and the dairy can even take their water provide from this irrigation system. The key requirements of the venture had been value efficiency and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and make certain that the water delivered to the surface is transferred on to the upper tank. pressure gauge วัด แรง ดัน function a PID controller with suggestions that permits the water level within the tanks and boreholes to be monitored and corrected. This is finished by alternating between the completely different pumps and regularly monitoring the flow. If the borehole stage falls under a minimum predetermined by the person, the PLC management switches to the following the borehole and prevents the pumps from being damaged.
The system has various Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and hold the water level above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC screens the water stage within the high reservoir and the animal watering stations, whereas a further DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 series are used to show all of the processes within the system and show system information and warning indicators on a 7 or 15-in contact display screen. In-house software program additionally allows the time configuration and energy costs to be monitored remotely. Users can even monitor the whole course of via the DOP-100 VNC server.
The system is now working without any points and supplies both livestock and crops with adequate water, even in periods of low rainfall.
