净水机运行噪声的改善研究

Research on anti-odor technology of single system frost-free refrigerator

本文通过行业净水机的噪声对比,及A公司主流净水机新旧滤芯的噪声分析,提出净水机噪声主要由系统内部有空气导致电磁阀异响和稳压泵本身电机运行产生的噪音两方面造成。为解决此问题,本文提出了优化程序,增加隔音棉、隔音结构等整改措施,并提出了异响智能检测的方案。

In this article, the noise of three kinds water purifiers sold in local markets were choose to compare noise level. Furthermore, the mainstream water purifier of A company with new and used filter elements were also being studied. The results show that the noise of water purifier is composed of magnet valve with air in the system and the noise of stabilized pressure pump body. To solve this problem, programs optimization, structure noise-insulation and a new schema of noise intelligent detecting are presented.
