Installation Method Of Combination Seals For Hydraulic Cylinders

The end user of the hydraulic cylinder is concerned with whether the hydraulic cylinder has a leak phenomenon, and the assembly quality of the seal directly determines the quality of the hydraulic cylinder sealing performance. Since the main sealing material of the hydraulic cylinder is mostly polyurethane, the hardness of the sealing member is obviously improved, and the use of the combined sealing member brings new challenges to the assembly of the hydraulic cylinder seal.

Improper assembly can easily damage the seal, causing leakage of the hydraulic cylinder. Therefore, an understanding of the combined seal assembly process is necessary.

IV. PTFE sealing ring is placed on the mounting mandrel and pushed into the piston groove;

V. Remove the mandrel from the piston;

VI. Push the recovery tool while pushing it, so that the restoration tool is completely placed on the outside of the seal, and take off the recovery tool after one minute.

2) Rod Combination Seals

The image shows the assembly is used for the sealing of the piston rod, such as the step ring for the shaft, the square ring for the shaft, the square ring of the shaft, the U-ring and the dust ring, which are assembled according to the following procedure. For the integral guide sleeve, it is recommended. The page's installation recovery tool.

2. Installation Steps

piston cleaning

I. Clean all guide sleeve parts, seals and recovery tools then apply lubricants;

shaped slide ring

II. Place the O-ring (NBR or FKM) in the guide sleeve;

o rings

The step ring is bent into the shape as shown above and placed in the guide sleeve. After loading, press the step ring with your fingers as much as possible to make it as round as possible;

4) Push the restoration tool shown on the previous page while pushing it into the hole, and then take it out for one minute and then remove the recovery tool.

The above will be the basic installation of piston and rod seals.
