Slurry pump mechanical seal installation and use

1, check the installation of the mechanical seal models, specifications are correct.
2, check the size of the slurry pump and mechanical seal installation site dimensions related to the accuracy and interrelationship with the technical requirements. Mainly in the following areas:
(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, the installation of mechanical seal process, should be kept clean, and not allowed to beat the sealing element with a tool to prevent damage and damage.
4, the 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, the mechanical seal of the rotating part, relying on the spring seat on the two fixed screws and shaft fixed, tighten the screws, to ensure the working length of the spring.
The use of slurry pump mechanical seal 1, slurry pump start, the need to check the mechanical seal attachment, cooling lubrication system is perfect smooth.
2, before starting the material line should be cleaned to prevent rust impurities into the sealed chamber.
3, hand drive coupling, check the shaft is easy to rotate, if the drive is heavy, need to check the installation dimensions are correct.
4, the normal drive, the need for static pressure test, check the mechanical seal face, seal ring and seal at the end of the sealing effect, if there is a problem, one by one to check and solve.
5, slurry pump start, should keep the sealed chamber filled with liquid or sealed medium, if a separate sealing system should be started, the cooling water system must also begin to circulate.
6, before normal use, the first atmospheric pressure operation, observe the sealed parts of the temperature rise is normal, whether the phenomenon of leakage. If there is a slight leakage, you can run together for some time, so that the face fit more evenly, until the leakage gradually reduced to normal so far. Such as running 1-3 hours, the amount of leakage is still not reduced, you need to stop inspection.
7, under normal working conditions, step-up heating can be slow, respectively, and pay attention to the end of the temperature rise and leakage, such as all normal, that can be put into production.
Parking, stop slurry pump, stop cooling lubrication system.
