Reduce or eliminate noise and vibration pilot relief valve, usually in the pilot valve portion plus home vibration absorption elements. Vibration absorption sets generally fixed before the pilot valve chamber, namely the resonance cavity, can not move freely. Consumers have put in all kinds of vibration damping holes, hydraulic repair company in order to increase the damping to eliminate vibration. In addition, since the resonant cavity of parts increases, so that the volume of the resonance chamber is reduced, increasing the rigidity in the negative pressure fluid, hydraulic phone, according to the principles of element stiffness less prone to resonance, hydraulic company phone, you can reduce the occurrence of resonance possibilities. Copper sleeve cylinder inserts, Xi'an hydraulic, can be used to replace copper sleeve for repair. First, a group of at plunger rod diameter trimmed to uniform size, then more than 1000 # sandpaper polished outer diameter. The heat and loading or copper cylinder sleeve cryogenic extrusion, interference assembly; mining of Loctite adhesive assembly, which we approach requires a copper jacket with a groove diameter surface; (c) bore tapping, copper sets the outer diameter of the thread processing, after applying Loctite glue, screw assembly.
