How do I know the foaming is caused by the Eductor? Well I have given a ball valve just before the Eductor and the eductor is on a bypass line. So when the valve is closed, there is no fluid going through the eductor thereby the suction of fluid from the tray stops and so does the foaming.
Hi guys, facing a bit of a problem here. Please see the system layout here : https://imgur.com/a/6d4XWxj#nZbOKG1
I've connected an eductor to the coolant pump in my machine. This eductor sucks the leaked cutting fluid from a tray underneath the machine I.e coolant passes through the...
@LittleInch not yet haha. Although I haven't used it everyday since I got it.
@CompositePro Understood. We are now thinking of making a machine that uses a compressed air driven venturi to generate the vacuum. Will this still be required? We have a venturi we used for another purpose available...
Hello, I have borrowed a Freddy Vacuum Cleaning System from a friend since I wanted to use it on my CNC. We used it for removing the floating hydraulic oil from the coolant surface but it also sucks a lot of good coolant.
We then started looking for Freddy videos and found this -...
Hello,
Thinking of building a pilot project for one of my customers wherein I install simple flow sensors on multiple machines and connect their outputs to an IIOT gateway. Now the issue is that because of budget restrictions, I can only afford very basic flow sensors meant for water (the hall...
@LittleInch
Thanks for your response.
I cannot use water since that will need another tank to store the water & recovered 'oil+coolant' coming out of the venturi.. thereby defeating the purpose of having a small and perhaps portable solution.
Can those Oil coalescing cartridge filters work if...
Hello, was wondering if I could pass compressed air through a venturi pump to pull floating oil from a tank? If yes, how do I control the eventual mixing of oil with the air from the outlet end?
The requirement is given to me by one of my clients who wants an easy, and low-cost solution to...
Hello guys,
I am supplying a Venturi Vac to my clients which is installed directly on their CNC Machine Coolant Pumps (photo attached).
This is done by introducing a Tee connection on the discharge end of the pump as shown. The straight line of the tee is connected to the hydraulic coolant...
Okay.. not sure if it'll work, but I have thought of something. What if I give the float a tapered top, with the tapered end entering the 11mm ID of the Dip Tube.. And I make a groove on the float at the interface between the 11mm & 12mm ID sections and attach an O-Ring.
Attached sketch for...
@Compositepro, another float below the device meaning outside of the Dip Tube? I am reducing the diameter of the bottom hole now. I need the hole so as to allow the float to rise freely when the water rises up to that level.
(therefore air flow, which entrains water).
Could you explain this bit...
@LittleInch, we increased the number of holes above the float and that has made a visible difference! The float does not get sucked up upon starting the air supply through the venturi. So yes that suggestion has worked out.
We've observed another problem though. Some water leaks past the float...
@LittleInch you mean the holes or the slots?
I will increase the size of the holes above the float and if possible the number of holes as well. Should I also make the slots on the side of the tube? Most similar products I've seen online usually have one of the two, never both.
@3DDave, Got it. Will give this a shot and report back here. Any other suggestions, please lay them on me. Thank you guys. Really hoping this will work. Shall revert here with the results of this as soon as possible.
