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...

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. We've observed another problem though. Some water leaks past the float and enters the venturi which then throws it out...

@jrmichler Thanks for that. Both these suggestions require making a new shut-off tube as I don't have a lot of space to play with in the current one to accommodate a longer float. I have been speaking to some people and they've asked me to try increasing the size of the holes above the float...

Hey guys, I have built a Compressed air venturi operated Drum Pump for my garage. The system consists of a horizontal venturi tube with a pipe (shut-off tube) that is inserted into the Drum. Turning on the venturi creates vacuum in the drum and thus liquid is sucked from outside and is collected...

Any help would be appreciated guys! Questions : 1. Pulsating flow out of the venturi might lead to foaming or atomization of the coolant? Or not? 2. For cases with a suction lift of less than a meter, are AODD pumps advisable or can I work with a centrifugal pump as well (for coolants..). If I...

Sorry for the delay in response. But here's what I've done this week :- Took a simple AODD pump and dropped its suction flexible pipe straight into the machine sump, discharge pipe from the pump connected to my Venturi, outlet of which is returned to the sump with another flexible pipe. Took...

Also my present system uses zero resources to make it happen, as we simply use the coolant from the pump. No air or electricity is required. The portable setup might require one of the two.

Sorry. I'll make it clearer. The diagram shows the coolant tank and plumbing of 'one' machine. The venturi is installed on the discharge end of the pump and the vacuum cup is placed in the swarf trolley of that particular machine. The 'To machine' is the hose that supplies coolant to the...

Hello, We make a Venturi vacuum system for recovering CNC coolant from the swarf trolley. It is a simple arrangement consisting of a venturi tube tee'd off the coolant pump and a stand-off placed at the bottom of the swarf trolley with a filter disc. Now the problem with this system is that it...

Thanks for this. One query... It appears as if the block would be resting on the screws extending from the bottom. Assuming the height of the block is approx. 28mm & I use 1.25" long screws (31.75mm), the screws would be extending past the block by 3.75mm. Will the venturi produce enough suction...

Yes making it wide and low like any vacuum suction cups is something I was thinking about as well. I don't know how I can add a magnetic clamp on this. Ideally it should stick to the surface due to the low-pressure (partial vacuum) created inside due to the venturi. But with those 25x2mm slots...

Hi guys, my second design (based on a Fox Valve venturi) is almost ready for trials. I will take my trials and comment here soon. Meanwhile I was wondering if you'll could shed some light on the Vacuum Cup. This cup shall stick to the bottom of the Swarf Bin. It has slots on its bottom for...

Hi Tom, this would have been ideal but the problem is that the Coolant (or chip) collection bins are supplied by the CNC Machine Tool manufacturer and aren't in our scope.

If I have understood you correctly, you are talking about the suction cup which I plan to leave on the Chips trolley. I have only made 25mm(width)*2mm (depth) grooves on the cup for the suction (see the attachment). This had occurred to us while designing that if the groove size would be too...

Also, I have now realized the diameter of the right side of the nozzle must be higher than the end point of the left nozzle (part where the liquid exits). Attached image FYR. Also, I guess the suction diameter needs to be higher? Any advice on this and anything else will be appreciated. Thanks.
