The connection method between the piston and the cylinder of the single-column hydraulic press

The sealing structure between the piston and the cylinder of the single-column hydraulic press mainly relies on the flange connection, but a suitable sealing device should be selected to avoid oil leakage. There is relative movement between the piston and the cylinder, and there is no leakage between the two cylinders. hydraulic cylinder. According to the working pressure and function of the hydraulic cylinder, the Yx type sealing ring is selected for sealing. Selected by the nominal diameter, the slot tolerance is H9 or H9, the hydraulic cylinder on the single-column hydraulic press is usually connected w, and the drive mechanism passes through the end of the piston rod.

The piston rod of this structure is usually a flange structure. In addition, the guide sleeve of the single-column hydraulic press on the piston rod is installed on the end cover of the hydraulic cylinder rod to guide the installation of the piston rod and the inner sealing device, so that the ring rod cavity is installed on the outside to prevent the piston rod from being damaged by impurities, dust and water sealing device. device.
