Embodiment Construction

[0016] The invention provides a method for arranging nozzles in a square spraying area with high spraying uniformity. In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following uses a square sprinkler nozzle as an example, and describes it in detail as follows in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, first, assuming that the 30-type square sprinkler head is used as the object, the working pressure range of the nozzle is set to be 250kPa to 400kPa. Through the test, the nozzle rotates once during the working process, and the pressure changes. When the pressure is 400kPa , the long range a of the square spraying area is 20m, and when the pressure is 250kPa, the short range b is 15m.

[0018] Secondly, the water distribution curve of the square sprinkler nozzle is measured, and the water distribution curve of the longest spraying range a and the water...

Abstract

The invention relates to a method for arranging non-circular spraying region sprayers, in particular to a method for arranging square spraying region sprayers. Firstly, the square spraying region sprayers serve as a model machine, the working pressure range of the sprayers is set to obtain the parameter of a long firing range a and the parameter of a short firing range b of a square spraying region. Secondly, two pipelines which are parallel are selected according to the character of water volume distribution of the square spraying region sprayers based on the non-leaking-spraying combination principle, the distance 1 between every two adjacent sprayers on the first pipeline is determined, the distance m between the first pipeline and the second pipeline are determined, and the sprayers on the second pipeline are right located between every two sprayers on the first pipeline. The method has the advantages that the tail end of the long firing range overlaps the tail end of the short firing range of the sprayers of the other rows, the spraying strength is equal to the single spraying region maximum spraying irrigation strength point value, leakage spraying does not exist, and the evenness of the square spraying region sprayer combination spraying is improved, and the combination uniformity coefficient is high.

Description

technical field [0001] The invention relates to a method for arranging nozzles in a non-circular spraying area, in particular to a method for arranging nozzles in a square spraying area with high uniformity. Background technique [0002] The square spraying area sprinkler refers to the variable spraying of the sprinkler to realize the square area. In general, with the change of the rotation angle of the non-circular sprinkler head, the range of the sprinkler will also change. For the water distribution of the square sprinkler head, the nozzle rotates 360 o , the range of the nozzle presents four periodic changes. : In the area with a longer range, the working pressure on the nozzle is greater, the water volume in the distance is less, and the water volume in the near area is more; in the area with a shorter range, the working pressure on the nozzle is small, and the water volume in the distance More, less water nearby. [0003] Whether the arrangement of sprinklers is re...
