l Mechanical seal components and their related assembly contact surface, before installation must be cleaned with acetone or anhydrous alcohol, do not promise to use unclean cloth to wipe the sealing surface. Device process should adhere to the clean, especially dynamic, static ring and auxiliary sealing elements should be free of impurities, dust. Apply a layer of clean oil or turbine oil on the appearance of dynamic and static rings. L tighten the gland should be carried out after the coupling is corrected. The bolts should be tightened evenly to avoid skewing the section of the gland, and the points should be checked with a ruler or special stuff, and the error should not be more than 0.05mm. Check the gland and shaft or bushing outer diameter of the *** with the gap (and flushness), must be wrapped around the average, with a plug ruler to check the tolerance of each point is not greater than 0.10 mm. L spring tightening should be carried out in accordance with the rules, do not promise to have a large or small scene, the requirements of the error ± 2.00 millimeters, over the General Assembly to increase the section than the pressure, accelerate section wear. Too small will form a lack of pressure and not play a sealing effect, spring mounted in the spring seat to move sensitive. When using a single spring, pay attention to the rotation of the spring, the rotation of the spring should be opposite to the transformation of the shaft bias. l dynamic ring device must adhere to the sensitive movement, the dynamic ring pressure to the spring should be able to actively pop back.
l First, the static ring sealing ring set in the back of the static ring, and then installed into the sealing end cap. Pay attention to the maintenance of the static ring cross-section, to ensure that the static ring cross-section and the end cover of the perpendicularity of the center line, and the back of the static ring anti-rotation groove aimed at the anti-rotation pins, but do not make contact with each other in. l device process should never be promised to use something directly knocking sealing elements, demand knocking, must use special things to knock, in order to prevent damage to the sealing elements l assembly of all sealing rings should be coated with water pipe water and other lubricants, so that you can prevent damage to the assembly process of the rubber ring. The sealing surface of the dynamic ring is coated with smooth grease between the sealing surfaces to avoid dynamic ring sealing surface wear before the pump is driven. l Floating ring assembly, must be careful not to touch the floating ring spring, so as not to affect the floating function of the floating ring after the spring touch down. Floating ring assembly, you can quietly press the floating ring to determine whether there is a superior floating function. When installing the seal, it should be held gently to avoid damaging the seal, and the seal and cavity should be scrubbed clean when installing the seal. l fastening mechanical seal gland when fastening bolts should be an average force, to avoid uneven force damage to the mechanical seal. On the quick release mechanical seal at the end of the whole assembly must not forget to locate the piece of radial movement away from the shaft position fixed.
