separation of Coolant lubricant by STA prenseted by E&W Industrial Service Asia Co., Ltd.
At Progress-Werke Oberkirch, a subcontractor to the automobile industry, deep-drawn
parts are manufactured from carbon or galvanized steels.
A problem arose on 2 Müller-Weingarten presses in which the cooling lubricant emulsion
had to be changed every week due to the increased concentration of foreign oils and fine
contamination. In addition, employees were suffering from skin irritations. A belt filter
which was already in use on the installation did not improve cleaning performance
adequately.
A water-miscible cooling lubricant (emulsion, added in a quantity of 8 – 12 %) is used at a
temperature of 30° C, the volume is about 1,000 l.
The emulsion is contaminated with hydraulic oil, belt greasing oil and fine abrasion
particles.
Solutions / Realization
STA installed a combination bath maintenance system, which consisted of an NZ-50
centrifuge separator and a DPS-350 oil separator in the bypass on the belt filter.
The feed pump uses a surface suction system to force the liquid to be cleaned from…
