Method of replacing water pump seal

The method of replacing the water pump seal, the water pump seal components analysis of the relevant contact surface, before installation must be cleaned with anhydrous alcohol. The installation and construction process should be kept clean, is the dynamic, static ring and auxiliary system seal should be free of impurities, dust. Apply clean engine oil or turbine oil to the surface of the moving and static rings.

The installation and construction process should be kept clean, is the dynamic, static ring and auxiliary system seal should be free of impurities, dust. Apply clean engine oil or turbine oil to the surface of the moving and static rings.

Check the fit clearance between the cover and the outer diameter of the shaft or sleeve to ensure that the circumference is uniform and not greaterCheck the tolerance of each point with a 0.10mm feeler gauge. When using a single spring, pay attention to the direction of rotation of the spring. The direction of rotation of the spring should be opposite to the direction of rotation of the shaft.

The retaining ring is installed to be movable and flexible, and can automatically rebound back against the spring of the ring. After the static ring sealing ring can be sleeved on the back of the static ring, it is installed in a sealing end cover. Pay attention to protect the static ring section, ensure the verticality between the static ring section and the center line of the end cover, align the anti-rotation groove on the back of the static ring with the anti-rotation pin, and do not make us contact with each other.

The installation tool will not allow direct tapping of the sealing element. If a jump is required, the jump must be used to preventWater pump sealWhether all sealing rings should be coated with soapy water and other lubricants during assembly, so that we can effectively avoid damage to the rubber ring during assembly and production. The sealing surface of the dynamic and static ring is designed to be coated with grease to prevent the sealing surface of the dynamic and static ring from wearing before the pump is started.

Water pump sealWhen assembling the floating ring, be careful not to touch the floating ring spring, so as not to affect the floating performance of the floating ring. After the floating ring is assembled, the floating ring can be gently pressed to determine whether there is a good floating ring performance. InstallationWater pump sealIt should be handled with care to prevent damage to the seal, and the seal cavity should be scrubbed clean during installation. The fastening bolts shall be evenly stressed during the sealing gland of the fastening machinery to prevent uneven damage and sealing of mechanical equipment. For the quick-loading mechanical seal, after the overall design and assembly are completed, don't forget to move the positioning piece radially away from the shaft and the position is not fixed.
