梳齿式滤袋折叠机设计与参数优化试验

本文针对人工折叠滤袋劳动强度大、生产率低等问题,设计了一种滤袋的自动折叠机。首先对梳齿式滤袋折叠机进行了方案设计和结构设计,对梳齿式滤袋折叠机折叠滤袋的过程进行了几何分析;开展了下压气缸输入压强、滤袋材质、下压气缸杆运行速度对下压气缸对滤袋推力的影响因素的三因素三水平正交试验。极差分析结果表明:下压气缸对滤袋推力的影响最大组合为A1B3C3,下压气缸对滤袋推力值为94.5 N;下压气缸对滤袋推力值最小组合为A3B2C1,下压气缸对滤袋推力值为20.2 N。方差分析结果表明:下压气缸输入压强和滤袋材质对下压气缸对滤袋推力的影响显著,下压气缸杆运行速度对下压气缸对滤袋推力的影响不显著。试验结果为滤袋折叠机的设计和开发提供了理论依据。This paper addresses issues such as the high labor intensity and low productivity associated with manually folding filter bags and proposes the design of an automatic filter bag folding machine. Initially, a conceptual and structural design was carried out for a comb-type filter bag folding machine, and a geometric analysis was performed on the filter bag folding process of the comb-type folding machine. A three-factor, three-level orthogonal experiment was conducted to examine the effects of the input pressure of the pressing cylinder, the filter bag material, and the operating speed of the pressing cylinder rod on the thrust exerted by the pressing cylinder on the filter bag. The range analysis results indicate that the combination producing the maximum thrust on the filter bag by the pressing cylinder is A1B3C3, with a thrust value of 94.5 N. Conversely, the combination yielding the minimum thrust is A3B2C1, with a thrust value of 20.2 N. The variance analysis results show that the input pressure of the pressing cylinder and the filter bag material significantly affect the thrust exerted by the pressing cylinder on the filter bag, while the operating speed of the pressing cylinder rod does not have a significant impact. The experimental results provide a theoretical basis for the design and development of the filter bag folding machine.

单次过滤和多次过滤在润滑油过滤的应用与实践

文章在探讨单次过滤和多次过滤模式的基础上,分析了过滤模式选择的原则以及润滑油过滤器的应用。多次过滤用于润滑油的基础油和成品罐的循环过滤,单次过滤用于润滑油的灌装过滤,两个模式的结合使用,更利于润滑油过滤目标的实现。使用绝对精度折叠滤袋无需改造当前过滤器系统,满足高清洁度要求且能实现较高灌装速度。
