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 ...
Validation of Ultrasonic Cleaners
what is the meaning of ultrasonic validation ? Validation is a process of demonstrating, through documented evidence, that a process, procedure, method, piece of equipment, or facility will consistently produce a product or result that meets predetermined specifications and quality attributes Establishing the process of fulfill for purpose. how this can be accomplished ? there are several methods to test ultrasonic systems, one of them is the cavimeter of Elma Schmidbauer GmbH the elma cavimeter is measuring the cavitation noise figure. to get precise measuring data it is important to measure the ultrasonic cleaner when it is new. With this measurement you got reliable data's as reference which can be used to compare all future measurements. according to previous studies of Elma this phenomena shows: effect of cavitation in ultrasound DISCUSSION & CONCLUSIONS have been made: It has been generally accepted t...
