What is Tramp Oil?
To remove tramp oil, you must first understand what it is. Tramp oil is unwanted oil that has mixed with cutting fluid (also known as coolant, lubricant, or metal working fluids). It is generated as a byproduct during metalworking operations.
This type of oil is a contaminant and a potential pollutant if not dealt with properly. It usually originates as lubrication seeping out from the slide-ways and washes into the coolant mixture. Tramp oil can also originate as the protective film with which the steel supplier coats the bar stock to prevent rusting, or as hydraulic oil leaks.
In extreme cases it can be seen as a film or skin on the surface of the dirty coolant or as floating specks. The odor in the air around contaminated sumps is also terrible.
Skimmers and Coalescers
Tramp oil skimmers are used to remove the tramp oil from the clean coolant. These are typically slowly rotating disks, tubes or oleophilic belts that are mounted and partially submerged below the coolant level.
As these moving parts rotate through the coolant, tramp oils cling to them as they pass a tramp separator or wiper before returning to the coolant sump. These wipers direct the waste to a container where it is collected for disposal.
To remove tramp oils, Zebra Skimmers manufactures rugged tramp oil disk, tube skimmers and Belt Skimmers. They also developed the Muscle™ coalescer that uses floating oil skimmers for removal from the surface of metalworking coolants.
All Zebra skimmers are designed as simple, trouble-free, economic solutions for removing free floating and mechanically dispersed old fluids from individual machine sumps.
Based on gravity flow and coalescence, Zebras disc, tube and belt skimmers can remove tramp oils to less than 1% in a single pass.
Skimmers have a value in today’s metal working industry as they help to extend the productive usage of soluble oil, semi-synthetic and synthetic coolants, as well as the cutting tool, increasing speed and productivity.
