What to pay attention to when repairing hydraulic seals

1. Direction of movement - First determine the direction of movement of the seal, such as reciprocating, rotating, spiraling or fixed.
2. Sealing the focus - For example, the determination of the active point is the inner diameter of the rod seal or the active point is the piston seal at the outer diameter.
3. Temperature class - Check the operating temperature from the original machine or evaluate the working temperature according to the actual working environment to determine the required materials. For a description of the temperature class, refer to the following production user notes.
4. Pressure rating - Check the relevant data from the original machine use instructions, or infer the working pressure level by observing the softness and structure of the original seal. For the description of the pressure level, please refer to the following production user precautions.
5. Size - Most users will choose the old samples that have been used. However, after using the seal for a period of time, the seal will be greatly affected by temperature, pressure and wear. The selection can only be used as a reference. A better way is to measure the size of the metal slot where the seal is located, which will be more accurate.
