Construction of simple exhaust systems in production workshops
Thread Content
Who can give some advice on how to build a simple exhaust system for a production workshop? It’s the kind that’s modified from a larger oil drum
I’ve never seen oil drums modified before, and I’d like to know how to do it. To remove the sulfuric acid at the bottom of the waste acid tank, where the bottom drain valve was damaged, a hydraulic ejector was used; water served as the power source, and pipes were inserted to draw out the acid for use. For a simple vacuum extraction device, one could consider using a ejector to create negative pressure, with compressed gas or liquid serving as the driving force.
