IH chemical pump pump medium temperature of -20 ℃ ~ 105 ℃, if necessary, the use of double-ended seal cooling device for chemical, petroleum, metallurgy, power, paper, food, pharmaceutical, environmental protection, wastewater treatment And synthetic fiber and other industries. Now to introduce IH type stainless steel chemical pump use precautions. IH stainless steel chemical pump IH stainless steel chemical pump Note IH stainless steel chemical pump according to different conditions of use to install different forms of mechanical seals, such as built-in single-end balanced and unbalanced, double-balanced and unbalanced Type, external mechanical seal and so on. > Depending on the type of seal used, 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 Only a few general points to note. 1. Because mechanical seals are generally suitable for use in clean, non-suspended media, flush piping should be carefully cleaned to prevent solid contaminants from entering the end face of the mechanical seal and void the seal. 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 carefully not allowed to 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, etc. should be washed before assembly, especially dynamic and static ring end surface, carefully wipe clean with a clean, soft cloth or cotton, and then coated with a layer of clean Grease or motor oil. 7. The assembly should pay attention to eliminate deviations, tighten the screws, tighten evenly to avoid deflection, the seal failure. 8. Properly adjust the amount of yellowing compression, the pump installed, the hand to move the rotor, you should feel the seal has a certain degree of compression of yellow, but can be brisk and flexible to rotate without clenching feeling. If you feel too tight or disk does not move, it should be appropriate to loose some. 9. For the mechanical seal with external flushing, open the flushing wave before starting, so that the sealed chamber is filled with sealing liquid. Parking, stop the pump first, after the closure of sealing fluid. Further Reading: pump valve pipe fittings Exhibition 2016 Exhibition of Information Industry, Internet (Xiamen) Technology Co., Ltd.
