some people ask me about what pump i use /setup.
i hope this will give some ideas and answers to other .
the pump is busch R5 ra series oil lubricated single stage.
I’m liking that setup you have . To see it all in the gallery from start to finish , you did a nice job with everything .
It realy looks nice.
i’m still researching what vaccum pump i should buy to start my projects.
Can you tell me whats the advantages of having a big tank in your vacuum system?
And are those valves vacuum tight?
Ball valves are airtight.
The reservoir delays and extends the time between the pump switching on and off, when using a vacuum switch.
yes The reservoir delays and extends the time between the pump switching on and off.
when i built this system i keep in mind many options , but i dont use at the time pressure switch . the reservoir also can be a safety for any resin enter the system .
Hi very nice setup
I have also a setup that I’m working on but I have an issue with connecting the vacuum switch
I have a Smc vacuum switch and an Edward pump
If you have a Smc maybe you have a way to connect it?
Thanks
Quite nice. I like the modded catch tank, so you can take the top off easily, AND digital QC gauge!
Very nice setup, resin trap and all it looks. I’ve got a twin cylinder Gast oilless that I’ve been planning to do something similar with for some time now. Have most materials here to weld it up but I lack the time.
The SMC needs to be powered by a power supply (12 or 24V, depending on your SMC.) That is the simple part: just wire 2 wires of the 3 wire connection.
The 3rd wire will need to operate a relais (traditional or solid state).
The relais switches the 115/230v pump.
Then you will need to fiddle a bit with the settings in the SMC. iirc set it at NPN, -0,5 bar for testing purposes (or any equivalent in other units, 15 inch Hg for instance) and a hysterese of 0,1 bar / 2 inch Hg). This should be enough for testing to see if you have the principle right. (pump switches on at startup, stops when -0,5 is reached, and back on at -0,4)
My failure was that I entered +0,5 instead of -0,5 bar… (stupid me)
When all works, you can re-adjust for the settings you need. (hysterese and pressure, the rest never will need adjustment anymore.)
Very nice work putting everything together.
Found assembly photos my bad lol.
Do you have certain parts oriented any particular way for a reason?
