HOME ꄲ PRODUCTS ꄲ Center Pivot Irrigation

Center Pivot Irrigation

The center pivot irrigation system, also known as central pivot irrigation or circular irrigation, consists of a central tower, spans including truss and tower, an overhang, and an optional end gun system. The central tower is fixed on pivot point, and during operation, each span rotates around the central tower, irrigating a circular or fan-shaped area. Several different sizes of spans and an overhang of different sizes can form any length which is suitable for your land. One unit of center pivot irrigation system can cover 8 to 100 hectares, meeting your special irrigation needs. There are some sprinkler options, which can be chosen according to local climate and crop requirements, and the irrigation rate ranges from 4 mm to 50 mm.

Control panel	1. It displays operating status, monitors in real time, and provides fault alarms.
	2.It features automatic shutdown/reverse functions, enabling sector irrigation (optional).
	3.Adjustable speed for the end span of the system.
	4.The enclosure is dustproof and waterproof.
	5.A lightning protection device can be installed if needed.
	6.Pump can be controlled by the control panel.
	7.The cumulative timer can display the total operating time of the system.

Tower box	1.The three types of tower boxes together form the control system for the span. The time relay in the terminal tower box can automatically cut off power to stop the machine, preventing accidents caused by tire slippage or obstacles in the tail span or other spans.
	2.Omron safety switch (micro switch): made in Japan.
	3.The isolating switch and contactor have a minimum heating current of 16 amps under a rated voltage of 600V.
