Solving Coupling Problems
Our customer had an issue with a DIN 11851 coupling. He had recently taken delivery of a new process unit for the factory and the coupling on the new unit didn’t exactly match the coupling on the existing unit. One half was 80mm and the other was 3”. The two halves screwed together, however, the internal diameters were different. One was 81mm and the other was 72.8mm. For several reasons, the client was unable to change the couplings and the issue needed to be resolved as quickly as possible.
Assessment
Our engineer was called in to discuss the problem. The customer had a possible solution they suggested implementing, using Nitrile rubber and an intricate seal design, but our engineer explained how this solution might not work due to material selection, design and cost.
Solution
Our engineer recommended a simpler, more cost-effective design, using Polyacetal and the customer trusted the approach.
Result
We produced a sample, which was tested by the customer and it proved a success. An order was then placed for several of the parts, which were delivered quickly, meaning the new processor was up and running in no time.
