In a high pressure situation, you need a hydraulic shaft seal that can handle the forces present. Hydraulic seals can be found on a wide range of machinery types. They work to keep particles and fluids where they belong as a machine operates. As such, hydraulic seals are an important part of many machines. Some hydraulic seals are made to work in a single direction, while others can be used in multiple directions. Here is a brief description of how most high pressure hydraulic shaft seals are made.
The Preparation Stage
First, an experienced technician will review the old seal and measure it. The technician will then visit the warehouse inventory to perfectly match the old seal with new material. Seals are commonly made from nitrile rubber or fluorocarbon rubber. After verifying that the sizes of the old and new seal materials match, the technician will enter the information in a database to select the type of seal to be made. The technician should double check that the sizes and materials are correct with the database records, then input the sizes to the database.
The Formation Stage
Once the information for the new hydraulic seals has been entered in the database, the technician is ready to start creating the new hydraulic seal. The technician should get the seal material ready to mount on a lathe before transferring the database information to the lathe machine. Then, the technician should review the tools for cutting before starting the lathe in the cutting machine. After following safety procedures, the technician can supervise the machine as it cuts the new hydraulic seal.
The Review Stage
Once the machine has finished cutting, the technician should carefully remove the new seal and inspect it against the old seal. When the technician is satisfied that the new hydraulic seal is properly made to a high quality standard, they can send it out for delivery to the customer.
