Rolling mill seals are important components to ensure stable operation and extend the service life of rolling mills. There are several key technical requirements that must be strictly followed during installation and maintenance.
Before installing rolling mill seals, adequate preparations must be made. The staff should carefully check the specifications, models and integrity of the seals to be installed to ensure that there are no missing parts or damage. At the same time, the sealing elements should be thoroughly cleaned to ensure that there are no foreign objects or dust on their surfaces to avoid adverse effects on the sealing effect.
The installation steps of rolling mill seals must be accurate. The geometric dimensions and processing accuracy of the parts must meet the requirements of the drawings, especially the dimensions for forming waterways. During installation, the actual installation position of the rotating parts should be clarified according to the assembly drawings, and reasonable adjustments should be made. At the same time, attention should be paid to the positioning and alignment of the parts during installation to ensure that the matching dimensions and clearances between the parts meet the requirements. After installation, the entire sealing device should be fully inspected and tested to ensure its normal operation and reliable sealing performance.
Daily maintenance is also the key to the long-term and stable operation of rolling mill seals. Before the actual start-up, the specific installation sequence of the mechanical seal and the configuration of all parts should be fully checked to ensure that all parts are in the correct position and are tightened without looseness. During the operation of the rolling mill, the lubrication of the bearing should be checked regularly to observe whether the lubricating oil is sufficient, whether there is oil leakage or excessive oil stains, and listen carefully to whether there is any abnormal sound when the bearing is running.
When the rolling mill seal fails, it should be checked and repaired in time. For example, if overheating and smoking problems occur, it may be caused by seal failure or insufficient lubrication. At this time, the installation of the seal and the condition of the lubricating oil should be checked, and corresponding repairs or replacements should be made. If water is found to enter the bearing box, it may be caused by seal failure or improper installation. The installation position and tightening of the seal should be checked, and necessary repairs or replacements should be made.
In summary, the installation and maintenance of the rolling mill seal is a highly technical and delicate job. Only by strictly following the key technical requirements can the long-term stable operation of the rolling mill seal be ensured, providing a strong guarantee for the overall performance and service life of the rolling mill.
