摘要
根据我国植保机械雾化喷头研究与使用的现状和特点,在分析喷头类型、使用及其磨损问题的基础上,分析了喷头的磨损形式及冲蚀因素,探讨了喷头材料和内部结构对磨损的影响,强化了研究雾化喷头的磨损规律对减缓喷头的磨损率,延长喷头使用时间,保证喷雾效果的重要性,提出了开展喷头失效检测和预测的思路和建议。
Based on the introduction of the types, application and wear problems of the spraying nozzles according to the status and characteristics of the spraying nozzles of plant protection machinery in China, the wear type and erosion wear factors of the spraying nozzles were analyzed. The influences of the spraying nozzle material and its inner structure on the wear were discussed, the significance of the research of wear regularity of the spraying nozzles was reinforced in order to retard its erosion speed, prolong its lifespan and assure its effects. Finally, some proposals on the invalidation examination and forecast of the spraying nozzles were put forward and discussed.
