The dust-proof ring of the four-column hydraulic machine is set on the outside of the piston rod or plunger seal ring to prevent foreign matter such as external dust and sand particles from entering the hydraulic cylinder, so as to avoid affecting the work of the hydraulic system of the four-column hydraulic machine and the service life of the hydraulic system components.
There are three basic types of rubber dust-proof rings for four-column hydraulic machines stipulated by national standards: the first type is a pure rubber ring, which is suitable for installation in the A-type sealed cavity to prevent dust; the second type is a metal The rubber ring of the skeleton, which is suitable for installation in the B-type sealed cavity for dust prevention; the third type is a rubber ring with two-way lip, which is suitable for installation in the C-shaped sealed cavity for dust prevention and auxiliary sealing The role of.
