Multistage centrifugal pump mechanical seal installation: To master the mechanical seal repair and maintenance, you must first know the mechanical seal works. Mechanical seal is made up of two sealing elements (static ring and ring) perpendicular to the axis, smooth and flat surface bonded with each other, and sealing means constituted for relative rotation. It is produced by the pressure of the sealing medium appropriate pressing force on the rotating ring together stationary ring contact surfaces (end), so that the two end faces closely, maintain liquid film between the end face of an extremely thin and to seal purposes. This layer of liquid, so that between the shaft seal is always in good condition. (5) The overhaul is better than not split well. Once the mechanical seal leakage will appear eager to overhaul, in fact, sometimes sealed and not damaged, just adjust the working conditions or the appropriate adjustments to seal leaks can be eliminated. This will not only avoid waste, and can develop their own fault judgment, the accumulation of maintenance experience, improve maintenance quality. Sealing ring is the ring and stationary ring collectively (below), are the most important elements of mechanical seals. Sealing ring largely determines the mechanical seal performance and life, therefore, it made a number of demands. 1. Have sufficient strength and rigidity. Under operating conditions (such as pressure, temperature and sliding velocity, etc.) without damaging 150ZJ-I-A50 mechanical seals, deformation should be as small as possible while still maintaining the sealing operating conditions fluctuate. 2. Seals should have sufficient hardness and corrosion resistance, in order to ensure a satisfactory service life under operating conditions. 3. Seal ring should have good thermal shock resistance. To this end 100ZJ-I-A50 mechanical seal, require materials with high thermal conductivity and a small linear expansion coefficient, and will not crack when subjected to thermal shock. 4. Seal ring should match the smaller friction coefficient and good self-lubricating, sealing ring material and sealing fluid also has good wettability. Work in the event of a short period of dry friction, does not damage the seal faces. 5. Seal ring should be simple, symmetrical and priorities with the overall structure. May also be combined (such as cassette type) sealing ring 150ZJ-I-C42 mechanical seal, try to avoid using the seal faces sprayed structure. 6. Sealing ring easier to manufacture, installation and maintenance to be convenient, the price is low. 150ZJ-I-A48 mechanical seals, mechanical seals, mining slurry pump supplied by Anguo City Pump Co., Ltd.
