When it comes to different technologies for industrial vacuum applications, none have been around as long as liquid ring. Originally developed at the turn of the 20th century, this relatively unchanged technology is still a common product used today.
How would you describe (or spell) the onomatopoeia that comes with the rush of air from opening a vacuum-sealed product? Is it a THOCK? Or a FUUUSH?
If you know the principles behind the rotary tooth compressor, then you’re well on your way to understanding the dry claw vacuum pump. While they perform opposite processes, the mechanisms are very similar.
Vacuum leaks manifest themselves differently than line leaks from compressed air systems. Audible noise, bubble testing and sometimes smells are common for pressurized systems but none of these tactics work for vacuum leaks. Vacuum leaks can result from physical holes in structures, contaminated seals or even gases that emit from the vessel walls.
In years past, industrial vacuum pumps were known for their loud operation, substantial amount of oil carryover, and large energy costs. No longer! Significant developments in vacuum pump technology have resulted in advances in the energy usage, reliability, noise levels, and overall performance of these machines.
