In October 1976, a North China Pilot Unit under the command of a machine department conducted a study on the “North China 12C Small Mobile Sprinkler” jointly developed by the Joint Design Team of Sprinkling Irrigation Machines in North China and the Agricultural Machinery Repair Factory of Quwo County in Shanxi Province Identification, the meeting agreed stereotypes, can be put into production. The irrigation machine consists of S195 (or X195) diesel engine, North China 3BZ-45 self-priming centrifugal pump, North China PY-50 nozzle, rubber wheel cart and 2 (1/2) hour moving pipe. This paper mainly introduces North PY-50 nozzle. Performance North China PT-50 nozzle is a single nozzle rocker type can be used for the whole
