我团于1974年4月研制成功了龙兵204型喷灌机(见图),其性能与配套机具见附表。该机与拖拉机配套,沿渠边行走,定点抽水喷灌。为了水泵底阀移动方便,安装有底阀绞架。喷管的喷射角与龙江—101型喷头相同。采用蜗轮机构旋转。推力球轴承、滑动轴承通过胶质油封与压力水隔离,从而改善了润滑条件,克 My group successfully developed in April 1974, Long Bing 204 irrigation machine (see photo), its performance and supporting equipment, see the attached table. The aircraft and tractors supporting, walking along the canal edge, designated pumping water sprinkler irrigation. In order to facilitate the movement of the pump valve at the end of the valve installed gallows. Spray nozzle spray nozzle and Longjiang -101 the same. Rotation using a worm gear. Thrust ball bearings, sliding bearings through the rubber seal and pressure water isolation, thereby improving the lubrication conditions, grams
