AI Technical Summary

Technical Problem

Existing cylinders generate noise due to friction during operation and are not lubricated in a timely manner, which affects the lifespan and performance of the equipment.

Method used

A low-noise cylinder was designed, which uses a pneumatic drive component to drive the deformation cylinder to expand and deform, thereby pushing the extrusion mechanism to automatically apply lubricant to the piston rod surface, achieving automatic lubrication.

Benefits of technology

It effectively reduces the noise of the cylinder during operation, improves the timeliness and uniformity of lubrication, and extends the service life of the equipment.
