Thank you all for the comments and interest in this new AndyMark product.
We have exhausted our efforts to get the right pump for the FIRST community, and now are experiencing the pressure to deliver. This work has been done during a compressed amount of time, over 4-5 months.
When we first put out the CFM numbers, I calculated them incorrectly, so the numbers were off. Also, I didn't update the Viair performance numbers, so their comparative analysis was not right. The previous Viair numbers were during a 13.8 volt test from Viair.
I put up an example on how the flow rate was calculated on each page (
Viair and the
1.1 Pump).

Any chance you can post the set up you used for other teams to recreate. Additionally it would be fantastic if you could compare with other legal compressor on the market such as:
- Viair 250C-IG
- Old KOP Thomas
- Thomas 215

As Billfred mentioned previously, we will test any reasonable pump on this same bench test. I *might* have an old KOP Thomas. I don't have the others. If you send them to me, I will test, post the results here, and then send them back. Put a note in the box saying "pump test" and give me your return address. Send to "AndyMark Pump Test, 2311 N. Washington St. Kokomo, IN 46901". Heck, we may even send the pump back with some surprises.

Yeah, there is a plastic inlet filter included (in the box) with the pump. It's just not on the picture. I will ask Brett to take another pic.

I'd suggest taking some plugs sized to fit the dump valve outlet and drill holes of various sizes through their end. The goal would be to create an orifice that causes the compressor to cycle on say 15-30 sec after the valve is first opened, with that particular stored volume.
Then record the cycle times over the length of a match.
It would also be interesting to see what happens when the orifice is sized so that the system is unable to build enough pressure to shut off during a normal match length. I know I've seen robots the compressor continues to run for the duration of the match either due to leaks or high demand.
Note if there are no spikes lying around a standard automotive relay could be substituted, just grab Andy's or maybe Danny's keys and borrow one. Just make sure it is for something mission critical like the fuel pump or PCM and not one they can do without like the AC compressor.  |
Hmmm. I will investigate Richard's test and see what we can do. Since we have a few things going on around here these days, I may not get to this very soon.
Thanks,
Andy
