PARTS CLEANING 56 PRODUCTION MACHINING :: MAY 2016 Oil/Water Separator Pulls Oily Rinse Water from the Rinse Tank Surface A frequent problem encountered in parts wash lines is the buildup of an oil layer on the rinse tank surface. When the rinsed parts are raised out of the tank, the oil layer re-contaminates the parts. The problem can be solved by continuously removing the oil layer from the surface of the rinse tank. In practice, however, the parts wash application has two additional requirements: 1) The temperature of the rinse water is typically about 160°F, and 2) the rinse water usually contains a low concentration of alkaline cleaner. The TKO- 10-HT, from Keller Products Inc., functions the same as the other Keller TKO products, but is resistant to the special rinse water operating conditions. A self-priming, air-operated diaphragm pump on the TKO- 10-HT pulls oily rinse water from the surface of the rinse tank through an inlet device and then through a flter to remove any foating solids. The fltered oil/water mixture is then pumped through the company's all-plastic separator element immersed in a separator tank. The oil-free water returns continuously to the rinse water tank at a high fow rate of 120 gallons per hour. The oil layer collects on the top of the separator tank and is occasionally drained into a waste oil container by opening the oil drain valve. No other operator attention is required. :: Keller Products Inc. 978-264-1911 kellerproducts.net Rapid Drying Metal Process Cleaner Manufacturers using vacuum drying, air knife drying or any high impact air drying of parts in their cleaning operations often experi- ence challenges including corrosion, de-wetting and residue buildup. Vacuum drying and aggressive blow-ofs often result in residual pooling and streaking of the cleaner along the fat, machined part surfaces. As a result, the residue needs to be removed before the part can be stored, increasing labor costs and decreasing production. In order to mitigate these challenges, Quaker Chemical Corp. has developed QuakerClean 680 VDA, a fast drying process cleaner, which delivers a consistent, imperceptible flm that protects against corrosion, the company says. Especially useful for any application that requires minimal residue after the fnal wash process, the cleaner cleans and protects ferrous and nonferrous surfaces in one process- ing step, simplifying operations and keeping inventory costs low. It is said to minimize foam under reasonable soil load conditions and moderate pH for good operator acceptance. The cleaner is free of harmful substances. :: Quaker Chemical Corp. 800-523-7010 quakerchem.com
