Could you share a photo of this fine mesh screen if possible? I don't think I could understand much from the illustration in your post. Is it similar to those Oil Diffusers? Example -

So, I tried keeping the return line a bit elevated to ensure it doesn't get submerged in the coolant, and it DID NOT help! The coolant still foams the moment all the oil from the tray has been transferred and my device starts sucking air. I also thought I would try with a NRV above the Suction...

The foam occurs when the liquid(and air) is injected into the liquid in the tank, and NOT when the liquid is flowing through the pipe

This is what I am planning to try. The only problem with this is the pressure with which the liquid comes out of the pipe. Will have to make a simple clamp to hold it down.

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 : 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 venturi(let's call it motive) and returns to...

Last 30 minutes, I have been trying to use ChatGPT to help me with the geartrain and I guess this isn't as easy as I had thought initially as even the damn AI is struggling haha

Smallest issue with this.. if I mount the motor vertically (shaft pointing downwards), this will increase the total height of my gearbox (and machine). the input motor has to be mounted horizontally :headbang: What i meant by 'top' is actually where the topmost shaft is located. there are 3...

Yes but how will a horizontally mounted 450RPM gearmotor be able to transmit that 450 RPM vertically downwards (at right angle using bevel) AND give me 50 RPM in the same axis as the gearmotor? I thought about this but I am unable to think of a geartrain that will enable this. For eg. I will...

Sorry for the delay in my response, been busy with a lot of things and had to take some trials with the existing gearbox. Speeds are important. Ranges acceptable are 40-60RPM and 400-500RPM. In my illustration, the input gearmotor of 50RPM is actually connected to the top gear i.e 75T helical...

Hello, For a trial project (can't give details on what the project is at the moment sorry!), I have designed a gearbox that takes input from a DC gearmotor at 150RPM, and provides 2 outputs as per the following: 1. 32rpm in the same axis as the input. This drives the pulleys and the belt 2...

Here is the Eductor we have used. What do I need to change to increase the suction at the Suction Port? Meanwhile, I am trying the approach of adding another tube in parallel to the 2nd venturi. Shall update here.

Could you explain your first suggestion a bit more please? You mean to say that I have to add another tube in parallel to my current configuration (both venturis in series)? How is that going to solve the problem of the backpressure at the inlet of the 2nd venturi?

Hello guys, running a small project at a client's site wherein he has a problem of leakage from pumps and the machine's door causing cutting oil to start collecting in a tray kept beneath the machine. They are now using a Vacuum Cleaner to suck up this oil once every 30 minutes or so and this...
