Sprinklers are important equipment for irrigation. Nozzle quality, directly affect the quality of the project. Following Xiaobian and you learn how to select irrigation sprinkler. A good head, not only needs good mechanical function (simple structure, reliable operation, and its hydraulic) demand function is good, is also the primary skill needs satisfaction irrigation (combined irrigation soil strength is less than the promised sprinkler intensity, the droplet diameter is slight, the impact on Soil and crop water stress, the nozzle combination in the future spread evenly, and the water saving energy). These needs are often contradictory or restrict each other, so we choose portrayed in the front of the nozzle, should deepen the contact and influencing factors among know hydraulic parameters, so that the reasonable selection of the nozzle, so as to better fit the production needs.
The primary hydraulic parameters of rotary sprinkler are: operating pressure, spray volume, range, water dispersion pattern, sprinkler intensity and droplet impact strength (or droplet diameter or atomized target).
Generally speaking, we expect the nozzle to start the pressure and maximum pressure as wide as possible to the habit of different conditions. Under the same operating pressure nozzle flow some good, which means that the sprinkler head loss as small as possible, that the nozzle to smooth lubrication channels. In fact, sprinkler flow is usually measured. Under the same conditions, the greater the demand range the better, to reduce the contribution of the system. Second nozzle once selected, its parameters can also be directly checked by the product samples. When selecting the nozzle, we should first consider whether the hydraulic function of sprinkler can be used with sprinkler irrigation and soil conditions, that is to say, the demand of sprinkler irrigation quantity reaches the primary skill elements. The other, the strength of combined irrigation and demand uniformity is not only related with the combination of nozzle type, and nozzle and combination of I from coral is closely related to the three that must be synchronized.
