Mechanical seal is a sealing device used on the rotating shaft. Its role is to leak the medium without leakage and prevent liquid or gas leakage. The correct use and installation and maintenance of mechanical sealing are very important. The relevant content is introduced below.
1. Preparation before use
Before using mechanical seal, check the status of sealing components, bearing boxes, pump shells and other components to ensure that they meet the requirements of using mechanical sealing. At the same time, you also need to read the instructions related to mechanical sealing, clarify the steps of installation and inspection, and avoid wrong operations.
2. Installation
Installation of mechanical sealing needs to be operated according to the steps in the instructions to ensure that the sealing performance reaches the best level. Pay attention to the following points during the installation process:
(1) Wash the liquid or gas transmission of the liquid or gas transmission before installing, and clean the cover to eliminate small particles and debris.
(2) When installing mechanical sealing, it is necessary to ensure that the cover is perpendicular to the axial direction and keep it in the same plane.
(3) During the installation process, it is not allowed to use strong impacts to avoid the accuracy of the sealing component.
3. Maintenance
Regular maintenance of machinery sealing can extend its service life to ensure its sealing performance. The following points should be paid attention to during the maintenance process:
(1) Check whether the mechanical cover is running normally. If there are obvious wear or scratch, it should be replaced in time.
(2) Check the status of the cover before replacing the mechanical seal, and clean the cover and related components at the same time to ensure that there are no large particles in the bearing box and check whether it meets the standards.
(3) Check the spring, O -shaped ring, sealed ring, and seal seat to ensure that it has no damage and deformation, and confirm whether the sealing part can operate normally.
(4) When reinstallation, it is necessary to operate in accordance with the guidance in the instructions to install all components in normal order.
4. End
After the mechanical seal installation, use and maintenance are completed, the streaming system should be checked to ensure that all components are installed normally, tight and reliable, and no leakage occurs. If you have any questions or questions, contact the professionals to deal with it immediately.
