AI Technical Summary
Traditional cathode suspension structures are prone to corrosion in high temperature, high humidity and highly corrosive media environments, leading to wear and jamming of the threaded contact surface and a short service life.
It adopts a double-walled protective structure, including an outer shell and an inner shell forming an oil injection chamber. The inner shell has threads on the inside, and the bottom of the connecting rod has a threaded rod that mates with the sleeve. The oil injection chamber physically isolates acid mist corrosion and provides continuous lubrication. Combined with the observable design, it enables preventive maintenance.
It extends the service life of the suspension structure, reduces thread wear, and ensures the stability and reliability of the adjustment function.
