Beschreibung
Zusammenfassung:	The corrosion-resistant precision piston rod comprises a main rod, a fixed bottom ring is fixedly connected to the outer surface of the lower end of the main rod, a corrosion-resistant replacement sleeve is clamped to the outer surface of the upper end of the main rod in a sliding mode, and the fixed bottom ring and the corrosion-resistant replacement sleeve are clamped to the inner end of a hydraulic cylinder in a sliding mode. The inner end of the positioning groove is in threaded connection with a penetrating threaded rod, the lower end of the penetrating threaded rod is in threaded connection with the upper end of the fixed bottom ring, and the outer surface of the upper end of the penetrating threaded rod is fixedly connected with a plurality of outer torsion blocks at equal angles; a bearing threaded groove is formed in the middle end of the upper side of the penetrating threaded rod. The replaceable corrosion-resistant replacement sleeve replaces the piston rod body to make contact with the marine envi
