What did teams use for the vacuums in 2019?

[NustinJewton]

In 2019 a lot of teams ended up using some for of suction/vacuum. What were people using for this. Were they custom made mechanisms that pulled a vacuum or COTS parts? Thanks

[NustinJewton]

Yes I know this. I was wondering what they were using to pull the vacuum itself.

According to student notes, 971 used this pump for cargo and hatch panel suction

And 254 and 1619 used this pump for climbing hab

The 254 1619 pump worked well and wasn’t horrible to integrate. The 971 pump was light, but I wouldn’t recommend

2767 used a pair of automotive vane pumps driven by a 775pro. Needed some shaft modification to handle the motor setup. Not the quietest thing in the world…

@Mark_Wasserman care to spare some more details/images?

Edit: I want to stay it is the same or very similar to the previously listed pump.

[NustinJewton]

Thanks messing around and was gonna redesign for 2019 cause its my favorite game.

Just don’t forget to replace the motor that comes with the pump with a 775pro @NustinJewton

Here is a picture of 1923’s implementation. We used a pair of automotive vane pumps, pulled the pre installed motor, made a small coupler on the lathe, and attached a 775pro with a 3D printed adapter to fill the gap and adapt the mounting bolt pattern.

This is great thanks

[NustinJewton]

Also is there any chance you have the cad for the pump? Tried finding it online to no avail.

We used the same pump in the link for 971 that you provided and it worked great. We had a check valve on the end to prevent air leak also.

694 used an industrial suction cup pumped by a piston to some pretty good success

[Mclark2767]

The pump was from Hella but I don’t remember the model there were also accumulators for the climber to get the initial suction and we kept evacuating the air until the end of the match I believe.

Ditto for 2579. Had to replace the motor on it with a 9015 since the interface was for a D style shaft.

6328 also modified an automotive pump. We replaced the shaft, ran it through an empty cylinder in lieu of the motor, through a bearing in a plate to which a 775pro was also mounted. Power was transferred with a belt drive that gave some reduction, as the 775 ran a lot faster than the original motor. Worth noting was that the system worked best at less than 100% power - I think we ran at 80 or 90% most of the time, otherwise we popped the 30A breaker it was running on. It drew a very nice amount of suction. I think it’s still kicking around the shop, so if it’s useful I can find it and take a picture.
