气动油雾器测试标准及改进设计

Quality Test Standards and Evaluation of Pneumatic Lubricator

针对气动油雾器产品质量监督抽查和委托检测的结果,从行业标准入手简要介绍了油雾器的主要性能指标和测试方法 ,指出了主要存在的不合格项目。为解决压力降-空气流量性能不合格问题,在对油雾器进行结构分析的基础上,提出在不改变阻尼板材料和结构前提下,采用增加流通面积以增大流量的简单方法。并以某型号油雾器为例验证了方法的可行性和有效性。最后对油雾器行业标准的修订提出了几点建议。

Focusing on the quality supervision and testing results of pneumatic lubricator products, beginning with the industrial standard, the main performance indicators and testing method of compressed-air lubricators are briefly introduced, and the main existing unqualified items are indicated. In order to find out a solution of the unqualified performance of pressure drop-air flow rate, a simple method without changing the material and structure of the damping plate, by increasing the flow area to increase the flux, is put forward based on the structural analysis of the lubricator. Besides, the feasibility and effectiveness of the method are verified through a type of lubricator as an illustration. Finally, some suggestions on revision of the lubricator industrial standard are put forward.
