1. Check the installation of the slurry pump mechanical seal model, the specifications are correct.
2. Check the size of the parts associated with the installation of the mechanical seal and mechanical seal accuracy, geometric accuracy and correlation with the technical requirements.
(1) Allowable radial runout of the shaft (or sleeve) where the mechanical seal is installed, surface finish of the shaft (or sleeve), and tolerance of outside diameter dimensions.
(2) seal cavity and gland positioning end face of the shaft (or sleeve) centerline vertical tolerance tolerance.
(3) The end of the shaft (or sleeve) on which the moving ring seal is mounted, and the chamfer and finish of the end structure of the housing bore for the mechanical seal.
(4) The axial displacement of the mechanical seal shaft when working.
3. During the installation of the slurry pump, keep it clean and do not allow the tool to beat the sealing element to prevent damage and damage.
4 installation, moving, static ring surface should be coated with a layer of clean oil and turbine oil. Auxiliary seals (including moving ring seals and static ring seals) are also to be applied with a clean layer of engine oil or turbine oil before installation to ensure smooth installation.
5. The static ring seal set in the back of the static ring, into the sealed end cap, pay attention not to hurt the static end face, to ensure that the static end face and cover the centerline vertical, and pay attention to the back of the static ring to prevent trough to Alignment anti-sales, but can not touch.
6. Rotating part of the mechanical seal, relying on the two fixed screws on the spring seat and the shaft fixed, tighten the screws, to ensure the working length of the spring.
