How to install the glyd ring piston seal

Glyd ring seal is the cylinder seal, the general installation of o-ring after the installation of glyd ring rod wear ring.Small general use of direct installation method, first heating with oil, oil temperature can not be too high, wear-resistant ring on the sleeve to the shaft, and then ZD cooling.The large-size glyd ring material needs to use taper sleeve, from the small end of the sleeve to the big head, and finally pushed into the groove.

Step seal hydraulic also install an o-ring followed by a step seals, which is heated and then sheathed onto the shaft and then cooled. When installing the ring, press the ring inward a little in the direction of the diameter, then the wear ring is installed in the groove, and the pressure deformation is smoothed.When putting in the shaft must pay attention to see whether the shaft is fully set into the wear ring, and pay attention to the guide belt don't jam the shaft, or may be because the guide belt was extruded out of the groove after the damage to the stepseal.

In order to avoid damage to the seal lip and lead to the official use before the occurrence of leakage, installation should still be particularly careful:

(1)Sharp edges must be deburred and rounded, and chamfered according to the specific requirements of the installation.

(2)Threads, guide ring grooves, etc. should be covered, as seals can not be pushed over grooves, boreholes, and rough surfaces.

(3)Dust, dirt, debris and other foreign matter must be carefully cleared.

(4)Cylinders, pistons, piston rods and seals shall be oiled and greased prior to installation, taking into account the matching of the sealing medium.

(5)In heated oil or hot water (about 80 ° C-120 ° C) , the seal is easily expanded and restored to its original shape.

(6)Tools for installation shall be made of soft materials (e.g. polyamide) without any sharp edges.
