Used in all types of rotating equipment, pumps, To Suit industries such as general chemical, oil refining, petrochemical, pharmaceutical, pulp and paper, and wastewater treatment.
Used in the clean particle fluid, such as oil, hydrocarbons, aromatic hydrocarbons, organic solvents, weak acid, alkali liquid, water, ammonia water, etc
1. The assembly should be clean and smooth. The parts of mechanical seals, related machinery and equipment parts, tools, lubricating oil (grease), wipe materials (cotton yarn, white cloth, silk, etc.) must be very clean. The sealing end face of the dynamic and static ring should be wiped with white silk or soft gauze.
2. Trimming and chamfering rounds, chamfers such as shafts and sealed end caps should be trimmed smoothly, and the relevant rounded corners of the shaft and end caps should be sanded and polished.
3. During installation, apply turbine oil or l0 oil on the moving ring and static ring (especially on the seal end blood), auxiliary seal ring, shaft, and end cap to reduce friction, so as not to damage the seal of the static ring. End faces and auxiliary seals.
4. Assemble the auxiliary sealing ring.
1) The rubber auxiliary seal cannot be washed with gasoline or kerosene to avoid swelling and deformation and premature aging.
2) After the O-ring is installed on the moving ring assembly or static ring assembly, it should be logical to prevent it from being twisted, so that the burr is in the cross-section when it is in a free state. O-rings that are slightly rough on the burr can be used if the burr segment is 45o. However, care should be taken in the position of the burrs. When pushing the component, one side of the O-ring and the seal (gland or seal cavity) slide relative to each other. In position, it affects the sealing effect.
3) When pushing the assembly, prevent the O-ring from being damaged. The main forms of damage are drop, nick, bump, curl and twist.
5. Adjust the compression amount of the mechanical seal according to the technical requirements. For the value, refer to the product manual. Otherwise, the amount of compression is too large, which increases the specific pressure on the end face and accelerates the end face wear.
6. The static ring assembly should be installed into the gland (or sealed cavity) using a press or a drilling machine. Under no circumstances should mechanical seal parts or components be impacted. The pressed surface should be covered with clean paper or cloth to avoid damaging the sealed end.
7. After assembling the moving ring or static ring assembly, press the compensation ring by hand to check whether it is installed in place and whether it is flexible; elastic split ring (in some mechanical seals, the elastic split ring axially positions the compensation ring) Reliable positioning.
8. Check whether the perpendicularity between the sealed end and the centerline of the shaft (or sleeve) meets the requirements.
9. The anti-rotation pin lead of the static ring component must be accurate. When pushing the static ring component, the pin groove of the component must be aligned with the pin. After pushing in place, the distance from the end surface of the component to one end of the sealed cavity is determined to determine whether it is in place.
10. When tightening the end caps by tightening the bolts, use even force, symmetry, and care. Tighten it several times. Do not tighten it at one time to avoid deflection or even crushing of the static ring.
11. After the moving ring is installed, it must be ensured that it can move flexibly in the axial direction on the shaft (press the spring with the moving ring and then spring back freely).
