Delta delivers environment friendly irrigation to South African farmers

A pumping station powered by Delta CP2000 frequency drives is delivering environment friendly 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 ensure that the water delivered to the surface is transferred on to the higher tank.
The dairy farm wanted a pump system to entry floor water from wells and ensure a dependable and cost-effective water provide. 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 consultation course of, Pienaar Elektries opted for a number of automation products from Delta.
The deliberate irrigation system comprised two reservoirs at different heights, to be crammed with water by a complete of six underground properly pumps in a single day, when the energy costs had been low. A transport pump is used to switch water from the lower reservoir to the upper one. เกจวัดแรงดันลมดิจิตอล permits the sprinkler system to be operated using gravity alone during the day, making it notably efficient. The farm animals and the dairy can also take their water supply from this irrigation system. The key requirements of the venture were cost efficiency and low power consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground properly pumps and be positive that the water delivered to the surface is transferred on to the higher tank. The CP models function a PID controller with feedback that enables the water level within 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 minimal predetermined by the person, the PLC control switches to the following the borehole and prevents the pumps from being damaged.
The system has numerous Delta DVP collection programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water level above the predetermined value. เพรสเชอร์เกจ4นิ้ว regulate the motors. One DVP12SE PLC screens the water degree within the prime reservoir and the animal watering stations, while an additional DVP controller manages the sprinkler installation. Two human-machine interfaces (HMI) from the DOP-100 series are used to display all the processes within the system and show system info and warning indicators on a 7 or 15-in contact screen. In-house software program additionally permits the time configuration and power prices to be monitored remotely. Users can even monitor the complete course of by way of the DOP-100 VNC server.
The system is now working with none issues and supplies both livestock and crops with adequate water, even during times of low rainfall.
