The controller is microcomputer intelligent control. The photovoltaic controller has overcharge and over discharge functions, output short circuit protection, light control and time control functions, and is tested by the indicators of the Industrial Product Quality Supervision and Inspection Center of the Ministry of Information Industry. With constant current, soft start, half power, reverse connection, lightning protection, temperature compensation and other protection functions. It is marked with charging, over-discharging, load, display indicator, and the cable is made of national standard 4.0 mm2 wire.

Sprinklers are also known as sprinklers and sprinklers. It is very important in agriculture and water conservancy. The sprinkler is a kind of power machine, pump, pipeline, nozzle, mobile device and other facilities. According to the sprinkler irrigation method, the integrated sprinkler irrigation equipment is used to spray the pressurized water to the low air, and after atomization, it falls to the crop and the ground surface uniformly like raindrops. The type and function of the sprinkler is also very extensive. Below we will talk about the advantages and disadvantages of the center pivot sprinkler.

Sprinkler technology Sprinkler irrigation is the irrigation water through the sprinkler system (or sprinkler equipment), the formation of a certain pressure of water, spray from the nozzle to the air, the formation of water droplets, sprinkle irrigation in the soil surface, crop growth to provide the necessary water.

The ring is called the slip ring, the conductive ring, the confluence ring, the collecting ring, the rotating conductive joint, etc. Generally, the slip ring is the asynchronous motor, and the collecting ring is the DC motor. The same conductive slip ring can be matched according to the current mounting hole, commonly used for motors, generators, packaging machinery, electronic test equipment, medical equipment, rotary workstations, exhibition and display equipment, manufacturing and handling control equipment, rotating equipment.
