Vacuum cleaning furnaces https:\/\/8ruiyan.com\/en\/all-vacuum-cleaning-furnaces\/<\/a> need reliable pumps. The pump removes gases and vapors during the cleaning process. Two common types are the\u00a0water ring vacuum pump<\/strong>\u00a0and the\u00a0oil-sealed rotary vane pump<\/strong>\u00a0(often called oil pump). How do they work? Are they the same? And what about emissions? Let\u2019s break it down.<\/p>\n\n\n\n

Operating Principles: Not the Same<\/h2>\n\n\n\n

Water ring pump<\/strong> uses water as a sealing liquid. An impeller rotates inside a cylindrical body. The water forms a moving ring. This ring traps gas between the blades. The gas is compressed and discharged. Simple design. No oil inside.<\/p>\n\n\n\n

Oil pump<\/strong> uses oil for sealing and lubrication. The oil fills the gaps between moving parts. It also helps capture vapors. The rotating vanes push gas through the pump. Oil recirculates inside. It needs regular changes.<\/p>\n\n\n\n

So, no, the way they work is different<\/strong>. One relies on a water ring. The other uses oil as a working fluid.<\/p>\n\n\n\n

Impact on Emissions \u2013 Important Difference<\/h2>\n\n\n\n

This is where the two pumps differ greatly. Vacuum cleaning furnaces often deal with hydrocarbons, glue, and other residues. These substances enter the pump during operation.<\/p>\n\n\n\n
