What are the four principles of sprinkler irrigation

The working system of sprinkler irrigation system includes the spraying time of the nozzle at the working point, the number of working positions that the nozzle can spray every day, the number of nozzles sprayed at the same time each time and the rotation irrigation scheme. For the formulation of sprinkler irrigation work, the working parameters such as the spraying time of the nozzle at the working point, the number of working points that the nozzle can spray every day, and the number of nozzles that need to work at the same time need to be calculated according to the working parameter calculation formula of sprinkler irrigation equipment. The wheel irrigation grouping of nozzles shall be carried out according to the number of nozzles working at the same time and the layout of spraying points. The wheel grouting marshalling shall generally comply with the following principles:

1. The number of nozzles or flow of each round irrigation group shall be consistent as far as possible, and the difference in the number of nozzles working at the same time shall generally not exceed 1-3, so as to ensure the stable flow of the water pump and maintain the operation in the high-efficiency area. The number of sprinklers working at the same time in a round irrigation preparation group shall be approximately an integral multiple of the number of sprinklers on a branch pipe.

2. When several branch pipes work on one main pipe at the same time, appropriate water flow shall be dispersed to reduce the main pipe flow and head loss, and attention shall be paid to maintaining the balance of upper pipe flow.

3. The division of rotation irrigation group must consider the convenience of management and operation, and strive to be concise and regular. In order to facilitate operation and management, the number of nozzles, number of branch pipes, working pressure at control points, allowable variation range and other working parameters working at the same time under general conditions shall be given, and the list of wheel irrigation groups can also be given to facilitate operation and management of sprinkler irrigation machine.

4. The sprinkler irrigation machine is accompanied by the moving pipe sprinkler irrigation, and the principle of wheel irrigation group can also be adopted.
