Large drip irrigation center pivot irrigation system

COLDMAX AUTOMATIC IRRIGATION SYSTEM:

The hot sale center pivot irrigation system is mainly used for sprinkling a variety of field crops, industrial crops and pasture. The automated irrigation system characterizes high efficiency, reducing water and energy consumption, increasing yield and saving labor. Its electrical alignment control system is safe and reliable, the over-watering protection and automatic display unit save water and troubles. The systems are equipped with impact sprinkler with uniformity coefficient more than 85%, and can be used for the uniform application of chemicals and fertilizers. The systems can be operated on fields with slopes of up 25%.

The mechanized system for agricultural irrigation because of its low labor and maintenance requirements, convenience, flexibility, performance and easy operation. There are mainly 3 kinds of mechaised Irrigation as for example Center Pivot, Lateral Moves and the combination of the both.

When properly designed and operated, and equipped with high efficiency water applicators, a center pivot system conserves three precious resourceswater, energy and time.

Manufacturers have recently improved center pivot drive mechanisms (motors, gears and shafts), control devices, optional mainline pipe sizes and outlet spacings, span lengths, and structural strength. The first pivots produced in the 1950s were propelled by water motors. They operated at high pressures of 80 to 100 psi and were equipped with impact sprinklers and end guns that sprayed water toward the sky, resulting in significant evaporation losses and high energy use. Today, pivots are driven by electric or oil hydraulic motors located at each tower and guided by a central control panel. Pressures as low as 10 to 15 psi (at the pivot mainline) are usually adequate for properly designed LESA (low elevation spray application) and LEPA (low energy precision application) pivots that are 1/4 mile long operating on level to moderately sloping fields. Water application efficiency with such systems is 85 to 98 percent.
