I came up with this monster beckett by daydreaming

[blueheaven]

Hi guys, the holidays are here and I had actually "dreamed" up this skimmer design while daydreaming.

Hope you guys like it.

If it is functional, I might turn it into reality some day

[NavIgatoR]

woo looks kind of fat to me...hehehe

[blueheaven]

Yep, it's supposed to be a fusion of BK and Beckett

[akahoshi]

wah bro.. even in your daydreaming also thinking so cheem stuff.. haha..

[RAV-65]

Bro,

care to explain where's the uniqueness of your skimmer besides the dimensions? Seems like a normal beckett skimmer to me... except it's fatter...

[blueheaven]

Nothing much unique about it la (came up while daydreaming, what you expect? )

I'm looking at 24 inch height 10 inch diameter

Hope I can achieve the same foaming capabilities as the BK

[blueheaven]

You guys think that short and fat would be better than skinny and tall?

See all those new needlewheels are all short and fat

[weileong]

There is a reason for being short and fat, shorter means lower resistance for the needlewheel pump hence they draw in more air.

[blueheaven]

Oh that's something new

Anyway, was wondering wouldn't those tall becketts have big bubbles at the top?

Since the needlewheels are short, the bubbles would not be so huge and thus have better foaming?

[AlfaRomeo]

Too short and it will be too turbulent and it will lead to overflow too. Its all about balance.

In this case you'll need to close the air tap.

[AlfaRomeo]

In this case you'll need to close the air tap.

and closing the airtap will reduce the L/hr of air going into the body. LPPL

Before you got eat your own LP and some pple's L, what happened to your LP theory of contact time and turn over rate?? LPPL right?

[AlfaRomeo]

The theory still holds in this case I think. For max contact/dwell time & turn-over rate, the chamber will need to be of a certain size (thus cannot be too short or small).

Optimally, contact time should be about 2 mins and at the same time turnover rate should be 1.5x-2x/day of total system water. This is of course assuming that there is a high l/hr of air being injected with suitably sized bubbles.

Weileong, sorry if I offended you with the LPPL thingie. Was not meant the way. Sorry once again.

[weileong]

Alfa, I did feel a little offended, maybe read your intention wrongly but that's always the case with internet post.

I offer you my apologies too.

Shorter chamber can be overcome with reduced air injection but that will reduced performance to a certain extend. Just look at the specification for deltec's AP702 and AP902 and you can see the difference in specification.

[AlfaRomeo]

Cool! Lucky both of us matured enuff.. no need to KPKB like the rest of ppl here. hehehe

Will compare the AP702 and AP902 and see what we can figure out

[weileong]

Actually what BH is talking about is a beckett so that air flow can be controlled by the diameter and the length of the downtube. With a properly choosen pump it should not have too much turbulence.

[blueheaven]

Yeah you are right, I am concerned with the turbulence caused by the shortness but I don't really understand the part about the downtube.

I have also measured, the min height I need is about 30 inches so is that enough to lower any turbulences?

[hamannbmw]

How u measure ? and why ?

[blueheaven]

You see, my sump height only permits the output tube to be at around 30 inches so that it would not be taller than the neck.

Therefore, I must make it at least 30 inches tall

[blueheaven]

Saw that the BK has the injection plate with the holes to reduce turbulence. You guys think that will work on a beckett?

[blueheaven]

I was wondering, why can't beckett injectors be made like this?

Not only it receives higher pressured water, it is supposed to be used upside down in pactical use right?

[hotlemond]

why go against the force of gravity at the beckett injection?

[blueheaven]

With water coming straight out of the pump to the injector, I think gravity would not play much of a part here

[hotlemond]

isn't it easier for water to travel before than after the injector?

well, after all you may still get it to work.

I was also looking at if water inside the injector housing be held at 1/4 level for air to enter the 4 venturi holes. Or you are thinking about absolute water tight?
