Spray irrigation machinery through a set of pipes to the pump out of a certain pressure of water transported to the sprayer, like the water ejected like rain, for irrigation. Spray irrigation machinery generally consists of three parts: water supply part, water transmission pipe and sprayer. Water supply part includes water source, water pump and power engine. The water source includes motor Wells, water pools or ditches. The power is generally an electric motor or an internal combustion engine. The pump generally adopts self-suction centrifugal pump, used to supply water to the water pipeline. Water transmission pipeline generally includes the main pipe, branch pipe, riser, gate valve and the connection of the pipe quick joint. The function of the water pipeline is to give the water pumped from the pump to the sprayer. Sprayer is the most important working part, commonly used as rotary sprayer and fixed sprayer.
Rotary sprayer is also known as a jet sprayer. It is composed of flow channel section, rotation mechanism, reversing mechanism and water flow crushing mechanism, etc. At work, the pressure water flows through the flow channel, forming a concentrated water flow from the nozzle. Under the action of the crushing mechanism, the water flow is crushed into small water droplets. At the same time, the rotating mechanism can rotate the sprayer evenly, so that the water is sprayed around the sprayer. Therefore, it has a long range, large flow range, low irrigation strength, high uniformity, is the basic form of medium range and long range sprayer, is also a widely used at home and abroad. The rotary sprayer can be divided into impeller type, impeller type and rocker arm type.
