ICS65.060.35 B91 National Standards of People's Republic of China GB/T 19797-2012/ISO 11545.2009 Replacing GB/T 19797-2005 Center pivot irrigation equipment and Translational Determination of sprinkler water distribution uniformity (ISO 11545.2009, IDT) Issued on. 2012-12-31 2013-07-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard rule according to GB/T 1.1-2009 given draft. This standard replaces GB/T 19797-2005 "Agricultural irrigation equipment center pivot irrigation machines and pan of water distribution uniformity Determination. " This standard compared with GB/T 19797-2005, the main technical changes as follows. --- Increased scope for irrigation apparatus height requirements; --- Terms and definitions to add a "rotating head" and "non-rotating sprinkler irrigation," the two terms; --- 3.1.1 adjust the height and diameter of the opening cylinder moderate requirements; --- 3.2.5 adjusted wind speed requirements. This standard uses the translation method identical with ISO 11545.2009 "Agricultural irrigation equipment and translation center pivot sprinkler water Distribution measurement uniformity. " For ease of use, this standard made the following editorial changes. Increase the number of the formula. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee (SAC/TC201) Agricultural machinery centralized. This standard was drafted. Technical Research Center of Fluid Machinery Engineering, Jiangsu University, Chinese Academy of Agricultural Mechanization Sciences. The main drafters of this standard. Wang Yang, Zhang Xian Sheng, Jin Hongzhi, Tang Yue, Li, Liu Junping, Zhu Societe Generale. This standard replaces the standards previously issued as follows. --- GB/T 19797-2005. GB/T 19797-2012/ISO 11545.2009 Center pivot irrigation equipment and Translational Determination of sprinkler water distribution uniformity1 ScopeThis standard specifies the configuration of the field water rotating or non-rotating sprinkler and center pivot sprinkler translational distribution uniformity Determination and water distribution uniformity coefficient calculation method. This standard applies to irrigation apparatus height from the ground 1.5m or more consecutive spray generating center pivot peace overlapping water distribution Portable sprinkler. This standard does not apply to angular arm equipped center pivot irrigation system.2 Terms and definitionsThe following terms and definitions apply to this document. 2.1 Center pivot irrigation system centre-pivotirrigationmachine A plurality of self-propelled tower car supporting pipes, rotating about a central support axis automatic sprinkler water through the central support shaft into the sprinkler along Radial flow from the pipe mounted on the rotating or non-rotating sprinkler to spray the field. 2.2 Translation sprinkler movinglateralirrigationmachine A plurality of self-propelled tower car supporting lateral pipes, pipe substantially in a straight line, in the field of walking a straight line trajectory for irrigation A rectangular area of \u200b\u200bautomated sprinkler. Water can be administered to any track point into the irrigation machine, installed in the pipe by a rotary or non-rotary Spray nozzle to the field. 2.3 Rotating sprinkler nozzle Various models of sprinklers, such as sprinkler, fixed nozzle, sprinkler gun. 2.4 Non-rotating sprinkler irrigation irrigationsprayer No rotational movement of the parts, a thin stream of water spray form or fan-shaped spray device. 2.5 Nozzle assembly sprinklerpackage A group of devices mounted on center pivot irrigation machines or translating the outlet pipe. The device may be moving parts, pipes, pressure (Or flow), and adjusting means to meet the needs of a particular sprinkler and a special set to achieve the required operating parameters support the pipe components. 2.6 End gun endgun Mounted on center pivot irrigation machines or pan the end to add one or more rotating or non-rotating sprinkler irrigation area. The end of the gun is usually within a period running only to make some kind of spray irrigation machine boundaries. 2.7 Test pressure testpressure In the center pivot irrigation machines or pan rack inlet pipe at the top of the first tee or elbow downstream of the measured pressure.
