Key points for the installation and use of mechanical seals: 1. When installing, a layer of clean machine oil should be applied to the surfaces in contact with the seal, to facilitate smooth installation； 2. The sealed chamber of the equipment must be kept clean during installation; the sealing components should be cleaned to ensure that the sealing surfaces remain intact, thereby preventing impurities and dust from entering the sealed area ； 3. During installation, it is strictly prohibited to strike or impact the device, to avoid damaging the mechanical seal and resulting in sealing failure ； 4. The radial runout of the equipment’s rotating shaft should be ≤ 0.04 millimeters, and the axial displacement must not exceed 0.1 millimeters ； 5. When installing the static ring gland, the screws must be tightened evenly to ensure that the end face of the static ring is perpendicular to the shaft ； 6. After installation, pushing the moving ring by hand allows it to move freely on the shaft, with a certain degree of elasticity ； 7. After installation, turn the shaft by hand; it should not feel heavier or lighter in any way ； 8. The equipment must be filled with the medium before operation to prevent seal failure due to dry friction ； 9. For crystalline and granular media that are prone to caking, when the medium temperature exceeds 80°C, appropriate flushing, filtering, and cooling measures should be taken; for various auxiliary devices, please refer to the relevant standards for mechanical seals.
