Of all the specialized equipment we use on our reef tanks, we dare say none are as aquarium-specific as the needle wheel impellers that drive most of our protein skimmers. The design of the needle wheel impeller has been through so many incredible iterations over the years, and creative tinkerers are always coming up with new ways to re-create the concept.
针杆叶轮是对离心叶轮的专门修饰，旨在使转子通过空气和抽水的水混合物自由旋转，将泡沫切成泡沫中，将泡沫切成极为细的气泡的混合物。针对针轮叶轮的功能和设计，我们已经非常关注，以至于我们现在享受了创建它们的令人眼花and乱的多样性，我们中的一些人足够熟练地从日常的家居用品中脱颖而出，例如Bioballs，泡沫，网眼甚至热胶。
为了庆祝针杆叶轮对海洋水族馆和我们采用的蛋白质撇油器的重要意义，我们希望沿着各种针杆叶轮设计的记忆巷进行旅行。这绝不是全面的清单，它确实访问了几乎每种广泛的针头叶轮，但可以随意分享您的收藏夹，或者我们可能在下面的评论中错过了一些。
感谢Dirk Griffin提醒我们，这是第一个作为批量生产产品的针头弹射器之一，即Aqua Medic的尊贵的Turboflotor。Aquamedic采用了两种不同的设计设计，显然其中一个对其进行了一些网状轮动作，而我们过去曾经没有注意到。
This impeller made for Sedra pumps was many people’s first needle wheel protein skimmer – The Euro-Reef, now Reef Dynamics, and ASM protein skimmers are some of the most popular ever sold on a mass scale in the North American marine aquarium market.
尽管不完全是典型的针状叶轮，但此版本在Rio 600和Rio 800泵上使用了非常普遍的使用。“针头”切碎空气和水被扁平的桨叶所取代，并且这种泵和叶轮设计也非常广泛地分布在数千个悬挂在CPR Bakpaks之类的蛋白质撇渣器上。
以上版本是SICCE PSK-2500系列泵的上面使用的三个最广泛使用的针状轮叶轮设计，这些版本在广泛的蛋白质脱脂机制造商中非常受欢迎。
在上面，我们有一个由ATB创建的SICCE PSK系列的特殊设计的针杆叶轮。
这是Warner Marine提出的一个有趣的设计，Warner Marine是一种以螺旋方式排列的针头图案，尤其是用于单向电动机泵。
Here you can see how a modest design tweak of the needle wheel increased the performance. Old impeller on the left, newer one on the right with a slightly larger diameter and slightly longer pins.
This basic needle wheel design is commonly employed on smaller and lower powered protein skimmer pumps.
This large needle wheel by MRC was milled from a solid billet of plastic for use with heavy duty Blueline and external pumps.
在这里，您可以看到针头和常规叶轮之间的区别，该叶轮可在可控的小波DC泵上使用。
This newer design of a needle wheel is made on a flower-like arrangement of blades and it appears like it could really chop up the air water mixture.
The closed needle wheel design above by H&S, and below by Eden, are an interesting take on the concept of needle wheel impellers although they have yet to gain any significant traction.
The idea of using a mesh within the needle wheel impeller was hatched by aquarium DIYers and has since spread to be widely used in many different protein skimmers.
In a similar vein as the mesh needle wheel is this concept used by Xenoxon skimmers that uses a kind of hardened foam material.
Likewise, this aluminum alloy mesh concept from Euro Reef, now Reef Dynamics, is used on their smaller protein skimmers designed for nano reef tanks.
这种金属网状车轮设计曾经被皇家居民嘲笑，尽管看起来确实令人印象深刻，但我们认为它从来没有离开过Skunkworks实验室。
提出的最后一个主要的新针头概念是ATI的Gridwheel设计。我们以前在ATI PowerCone上使用过它，它确实会产生一些极为细的气泡。
此针头设计列表几乎是全面的，但是如果我们错过了任何可符合的针头发明的主要版本，请告诉我们。
