IH chemical pump can be installed according to different conditions of use of different forms of mechanical seals, (such as the built-in single-end balanced and unbalanced, double-balanced and unbalanced type, external mechanical seal, etc.). Depending on the type of seal selected, its use and precautions are different, the specific circumstances, please refer to the mechanical seal installation instructions, GB3215-82 "refinery, chemical and petrochemical process centrifugal pump general technical conditions", the following Bai Connaught pump valve only a few general points to note. IH chemical pump should pay attention to what matters 1. Because the mechanical seal is generally suitable for use in clean, non-suspended particles in the media, therefore, the newly installed pipeline systems and storage irrigation should be carefully washed to prevent solid impurities Into the mechanical seal face seal failure. 2. In the medium easy to crystallize, the use of mechanical seals should be noted that regular flushing. Before restarting after parking, clean the crystals on the mechanical seal. 3. Disassembly mechanical seal should be careful not to use hand hammer, iron and other percussion, so as not to damage the dynamic and static sealing surface. 4. If there is dirt can not be removed, should try to remove dirt, rinse and then remove, so as not to damage the sealing element. 5. Before installing the mechanical seal, check all sealing elements for failure or damage, if any, should be repaired or replaced. 6. Should be strictly check the moving ring and the stationary ring relative friction sealing surface, does not allow any minor scratches, bumps and other defects. All other parts, including the pump body, impeller, sealed chamber should be washed before assembly, especially moving and stationary ring end surface, carefully wipe clean with a clean, soft cloth or cotton yarn, then apply a layer of clean grease Or oil. 7. The assembly should pay attention to eliminate deviations, tighten the screws, tighten evenly to avoid deflection, the seal failure. 8. Correctly adjust the amount of compression spring, the pump is installed after the hand to move the rotor, the seal spring should feel both a certain amount of compression, but can be brisk and flexible rotation without clenching feeling. If you feel too tight or disk does not move, it should be appropriate to loose some. 9.IH chemical pump external seal on the mechanical seal, start washing the wave should be turned on before the seal cavity is filled with sealing liquid. Parking, stop the pump first, after the closure of sealing fluid. (Editor: LLX QQ :) Recommended reading: 2017 exhibition information Yiwu fair loading
