Our millwrights were performing some basic preventative maintenance procedures on a hydraulic press when they noticed a flow on a cylinder blind side when there should not be any flow. After some checking and customer involvement, NEMX millwrights found that the cylinder was bleeding under pressure. The operators confirmed this when they were approached stating that they have had some quality issues with the pressing parts.
Once the symptom of the system was found, the real digging needed to happen to find out where the root cause was. After some machine cycling and troubleshooting, it was found that there was considerable blow by on the cylinders. They also witnessed the cylinders over travel and bottom out on occasion.
Why this forging client chose NEMX:
NEMX was chosen due to price, ability, reputation within the industry and timeline plan.
How NEMX Responded:
NEMX ended up removing and completely rebuilding the two main cylinders, finding further damage to the cylinder housings. They added softeners to the cylinders to stop damage from bottoming out in the future and fully rebuilt the valve bank and reset the machine, all due to some sharp Millwright eyes that caught the flow that was not supposed to be there.
The client was extremely satisfied with our diagnosis and mobilization to find and fix the root cause. We have since enjoyed a trusting and fruitful relation minimizing downtime and identifying investment points that the client is able to budget for utilizing good preventive and predictive maintenance practices.
