[Three rain valve to recommend the star product - Mechanical seal mechanical seal] describes the preparatory work prior to installation issues and attention. After the completion of repair work above, you need to re-install the mechanical seal, before installing it must be prepared to work: 1, if the new machine to replace the seals, mechanical seals must be inspected models, specifications are correct, the quality meets the standards; 2, stationary ring the tail end of the anti-anti-rotation pin at the top of the slot should be kept axial clearance M7N-85 mechanical seal 1mm-2mm to avoid buffer failure; 3, dynamic and static ring face clean with alcohol, and the remaining metal parts with gasoline and clean with a clean compressed air, carefully check the heart works to ensure that dynamic and static ring sealing surface without any damage. Before assembly, two "0" shaped rubber ring should be coated with a layer of lubricating mechanical seals, dynamic and static ring face must not oiled. [Three rain valve to recommend the star product - Mechanical seal mechanical seal is introduced] refers to at least one pair of rotation axis perpendicular to the face in the fluid pressure and the compensation mechanism stretch (or magnetic) role and assist with the seal means for maintaining fluid leakage paste combined constituted prevent relative sliding. Elastic loading mechanism and secondary seal is metallic bellows mechanical seal we called metal bellows seal. In light mechanical seal, as well as the use of rubber bellows auxiliary seal, rubber bellows stretch limited M7N-95 mechanical seals, generally need to be supplemented to meet the load spring stretch. Here we take advantage of the mechanical seal is: a reliable seal, will not leak or leaks rarely use a longer period. Clean, no dead M7N-65 mechanical seal can prevent bacterial contamination. II. Long life, the correct choice of friction load than the pressure of the mechanical seal can be used 2 to 5 years, the longest useful to 9 years. III. Long service intervals, in the case of normal operation, no maintenance. Four shaft or sleeve from wear and tear.
