Hydraulic Seal Product Installation Method.

Hydraulic seal product installation method.


Hydraulic seal product installation instructions
First, the precautions before installation of hydraulic seal products

1. Before installing the hydraulic seal product, the surface of the hydraulic oil cylinder should be inspected first, and no burr, flash, etc. may damage the defect of the seal product.
2. It is required that chamfering must be installed on the cylinder body and the piston rod to facilitate the installation of the seal product.

3, dust, impurities, debris and other foreign objects must be carefully cleaned.
4. When installing, the sealing lip of the sealing product should be correctly positioned so that the sealing lip cannot be damaged. When using the thread or guide ring groove, special installation sleeve should be used for installation because the sealing product cannot be in the groove Drilled or rough surfaces are pushed directly over, which can damage the seal product.
5. The cylinder barrel, piston, piston rod and seal should be coated with lubricating oil or lubricating grease before installation, and have good compatibility with the sealing medium.
6, to ensure that the rubber seal is clean, do not allow dust and other impurities attached to the rubber seal products.
7. Do not screw the rubber seal ring into the groove when installing, so as to avoid twisting and rolling the rubber seal ring.

Second, the installation method
    According to the different materials and installation positions of seal products, it can be roughly divided into the following two methods:
1. Rubber seals, such as O-rings and Y-rings, can be directly stretched or bent by hand.
2. The sealing ring of plastic material such as polytetrafluoroethylene (PTFE) cannot be over-stretched. The heating method can be used during installation. When the temperature can be tolerated, it is heated in a hot oil of about 80°C. Tetrafluoroethylene (PTFE) seal materials can easily be expanded at high temperatures and can be restored after cooling.
    When installing, try to avoid excessive stretching of the hydraulic seals, so as to avoid permanent plastic deformation and affect the sealing performance.
