IH chemical pump mechanical seal to use matters needing attention

This mechanical seal installation guide is intended for the IH chemical pump, which can be equipped with various types of mechanical seals depending on the application conditions. These include built-in single-end balanced and unbalanced seals, double-end balanced and unbalanced seals, as well as external mechanical seals. The installation method varies depending on the specific type of seal used. For detailed instructions, please refer to the "Mechanical Seal Installation Instructions," GB3215-82, and the "General Technical Requirements for Centrifugal Pumps in Refineries, Chemical, and Petrochemical Processes." Below are some important notes to consider: 1. Mechanical seals are typically designed for use with clean, non-suspended media. Therefore, it is essential to thoroughly flush the newly installed piping system and liquid storage tanks before commissioning to prevent solid particles from entering the seal faces and causing leakage or failure. 2. When handling media that tends to crystallize, regular flushing of the mechanical seal is necessary. Before restarting after a shutdown, make sure to remove any crystals that may have formed on the seal face to avoid damage and ensure proper sealing performance. 3. When removing the mechanical seal, avoid using hammers or other tools that could cause impact. This helps prevent damage to the dynamic and static sealing surfaces, which are critical for maintaining the integrity of the seal. 4. If there is dirt or debris present, do not force removal. Instead, try to clean the area first using appropriate methods, such as rinsing, before attempting to disassemble the seal. This prevents unnecessary damage to the seal components. 5. Before installing the mechanical seal, inspect all sealing elements for signs of damage or wear. If any issues are found, the parts should be repaired or replaced immediately to ensure reliable operation. 6. It is crucial to check the friction surfaces of the rotating and stationary rings for any scratches, dents, or imperfections. Any minor defects can lead to premature seal failure. Additionally, the pump housing, impeller, and seal chamber must be thoroughly cleaned before assembly. Pay special attention to the end faces of the dynamic and static rings—clean them carefully with a soft cloth or cotton yarn, and apply a thin layer of clean grease or oil before installation. 7. During the assembly process, ensure that all components are aligned properly. Tighten the bolts evenly and avoid any misalignment, as this can cause uneven stress and lead to seal failure. 8. Adjust the spring compression correctly. After installation, manually rotate the rotor to check the seal’s movement. The spring should offer some resistance but still allow smooth and flexible rotation without feeling stuck. If the seal feels too tight or does not move freely, adjust the compression accordingly. 9. For mechanical seals with external flushing, always open the flushing fluid before filling the seal chamber with the sealing liquid. When shutting down the pump, stop the pump first, then close the flushing fluid supply to prevent backflow and maintain seal integrity. Following these guidelines will help ensure the proper function and long service life of the mechanical seal in your IH chemical pump.
