An example of implementing measures to prevent recurrence by adding a slope during the replacement and installation of cylinders and associated parts.

This is a request for replacement due to malfunction of the cylinder operation of a cutting machine from an electrical machinery manufacturer. The hydraulic and pneumatic combined cylinder had hydraulic oil flowing back from inside, causing the weight of the cable carrier and bracket to be applied to the fixed cylinder. This resulted in the cylinder piston becoming eccentric, which led to oil flowing back through the gap. We replaced the cylinder and associated parts, injected oil, and bled air, ensuring that there was no oil spillage at the work site by taking precautions. After confirming the operation, we completed the work and submitted a work report. [Work Details] ■ Replacement of cylinder and associated parts ■ Oil injection and air bleeding ■ Operation confirmation ■ Work carried out by 2 personnel over 1 day *For more details, please refer to the PDF document or feel free to contact us.
