音响生产中分配铁磁流体

在工业扬声器生产中，将导电的铁磁流体作为润滑剂注入扬声器线圈已经30多年的历史。作为润滑剂，铁磁流体用于改善导热性及线圈振幅，辅助音频线圈定位，并且可以减少音效失真。铁磁流体的注入量对扬声器的音效影响非常大。而且，铁磁流体非常昂贵，价格通常在每升500-1000美元，一个控制精确的泵对节省铁磁流体也是非常关键的。

Ferrofluid is a conductive lubricant used for over 30 years in the speaker industry in the magnetic gap of the voice coil assembly. It serves as a lubricant, improves thermal power & damping, aids in voice coil centering, and reduces distortion. The quantity dispensed is critical since it affects many of the speaker's characteristics. In addition, ferrofluid is a relatively expensive fluid, ranging from $500 to $1000 per liter, and an accurate pump can pay for itself in fluid saved.

除了其非常精确的特点外，弗洛德计量泵还具有独一无二的无阀设计，整个泵只有一个活动部件。内部组件采用蓝宝石硬质陶瓷结构，具有非常优良的耐磨性，能够连续运行数百万次而不需要停机维护。链接中是2006年《音响线圈》杂志的文章，详细介绍了用弗洛德计量泵分配铁磁流体的独特优势，您能够理解为何弗洛德泵可以在短短18天即收回泵的投入。

In addition to being extremely accurate, the pump is a unique valveless design having only one moving part.  Sapphire-hard ceramic internal components resist wear and provide millions of dispenses without downtime for routine maintenance.  The linked article appeared in the June 2006 edition of Voice Coil magazine, and details the distinct advantages of using an FMI pump for ferrofluid dispensing, and how the FMI pump virtually pays for itself in 18 days!.
