Cylinder repair with optimisation Example press cylinder
Example: old cylinder before repair
Application: 2 plunger cylinders as a unit for the setting of rollers in a granulate press
Problem: Application discussed with the operator, Damage survey of the destroyed cylinder
Cause of failure: single-acting lip seal becomes leaks after a certain time.
The hydraulic oil does not exchange, no oil circulation, The scraper is pressed out of the cylinder by overpressure scraper is pressed out of the cylinder
Solution: The cylinder is equipped with a cover in which the wiper is located
The seal is designed in the plunger downwards as a piston seal
Additional venting and leakage oil borehole these can also be used as flushing holes. used as a flushing hole
