Customizing a Three Chamber Pass Through Washer with Dip Tank

AEC Systems USA was presented with a cleaning problem that didn’t fall into the traditional washer solutions. Our customer had used standard cabinet style washers to clean the inside and outside of canister engine liners with only varying degrees of success. In the discovery portion of the process we determined that the client’s current washer cleaned these liners at a rate of one liner every 2.5 minutes and the parts were washed, rinsed and dried. After this point in the customer’s current process, the parts were transported to a separate rust preventative dip tank. Between the wash process and rust-prevention process, every eighth part needed to be examined and gauged for tolerances. All of these processes were very labor intensive and our customer was looking to reduce labor to one person. The customer also had space constraints – a very limited work envelope that they were trying to stay within. Finally, the canister engine liners had unique features that made them difficult to get completely dry. This client needed a parts washer specifically designed to solve these time, space, and financial complications.

AEC Systems USA presented the customer with a three-station, auto-feed, guillotine-door pass-through washer. The first chamber washed the liner on a turntable with retracting center nozzle in order to fully clean both the inside and outside of the liner. The second stage, also a turntable with retractable center nozzle, was both a rinse and blow-off stage to provide a polishing rinse and dry. Once the part was washed, rinsed and dried, the liner moved out of the turntable chamber and was automatically lowered into a rust-prevention dip solution. Every eighth part was held, allowing the operator to remove it to check for machined tolerances. This solution modified the honing/washing operation from a three-person operation to a one-person operation, and we were able to design the parts washer to fit within the limited work envelope the customer’s space required.
