How many times can an autococker cycle per second?

I see you are now selling QEVs on your site now.

Have you benn getting good results with them?

Yes indeed. The QEVs do provide a measurable improvement to cycle speeds in several aplications.
In some setups, I can't see/measure any particular improvement but there seems to be no drawbacks to having them so we ordered a bunch more. Hopefully, with quantity breaks on the price, we'll be able to lower our selling price on them as well.

Nickel quick exaust valves

just to let you guys know i have clippard nickle quick exaust valves in. if you would like them they are $10 a piece, and we have black and chrome rams with qevs already installed, they are $50. if you would like to purchase them please email me at [email protected]

well, Paladin (cool name, like the band)
my statement about smaller bore rams is due to the testing and calculations I've done comparing 5/16 bore rams with 3/8 bore rams. when air density is taken into consideration, I noticed that the smaller 5/16 bore ram needed 43 percent more psi to create the same amount of force as the 3/8 bore, and it actually used a little less air to do the same job. I know it's not much but it got me thinking about air consumption at high rates of fire.

the response difference was only 2 msec. so it's tiny but I'll take what I can get.

running a little smaller ram at a little higher psi is not going to make too much of a difference on a solenoid valve as far as wear, but your right , I wouldn't recommend it for mechanical operation.

electrician,

on the "I know it's not much but it got me thinking about air consumption at high rates of fire." statement it would be a per shot air usage. I know, nitpicking.

Area per ram-

1/4 you have an area of 0.0491
5/16 you have an area of 0.0767
3/8 you have an area of 0.1104

or, per 10 psi + two cycles =

1/4 you use about .9 inch*lbs
5/16 you use about 1.5 inch*lbs
3/8 you have an area of 2.2 inch*lbs

if you have a sledge at 100 psi then you would use twice as much air per shot if you used a 3/8" instead of a 1/4". And 22in*lbs is almost 10% of a shot on most guns. That is a good chunk.

Also, if your using a Solenoid valve (ie, racegun) then a higher pressure will increase the switching time a small amount, but it would be rather small.

well I've come up with some numbers but they're not that large.

for the 5/16 bore ram at 40 psi I came up with .57 cu in at atmospheric for one total cycle.

your numbers seem kinda large, or I'm not reading it right.

I've just noticed that it is actually slightly more efficient to use a smaller bore ram to do the job. and if you make your gun more efficient in it's use of energy, it is more capable of high rof.
I've turned the lpr up in firing tests, looking for more speed to get higher rof, and it caused drop off. this tells me that efficiency is important these days for guns with high rof. I used to think, hey were building hot rods, not fuel economy guns. but in reality, the best hotrods, due get good gas mileage.

the e-blade orr-acle can do 14 easily (according to Rocky Knuth on Naughty Dogs)
He supposedly shoots 14 strait all game?

For ram information, including all kinds of dimensions, force calculations, etc. go to the Clippard web site.

It it very cool and exact for Clippard Products.

a cocker can shoot over 20bps

race gun and eblade and f5

over 20bps just need a halo

mech cockers can shoot as fast as you can pull same as a e-bladed cocker,only thing limiting it is the markers abity to go that fast they CAN cycle faster than 30 bps much. its just due to the long and heavy pull it takes much longer. E-blade's sear solinoid can cycle faster than 300cps

Teehee... threads in Deep Blue can get kinda old. Check the dates, and welcome to AO.

[Rokudon]

sorry, not really contirbuting, but wow, july 17, 2003. nice thread resurecton...?

[phantomhitman]

i read the first 5 pages of the thread and then passed out. did anyone ever agree what the autococker topped out at? i thought for sure that people had eblades and eblade2's over 15 bps shooting, not just cycling.
i have to get in front of a chrono that does bps and see how fast i can get mine up to, not like that matters though.

[PBX Ronin 23]

Max CPS is still to be determined. Obviously there are many variables involved here. But Max BPS seems to be 36bps and that's largely due to the current roster of available loaders.

[phantomhitman]

thanks for answering that. how fast have you seen an eblade go?
