Principles outlined edited by a pair of mechanical seal is cartridge mechanical seal or several vertical axis relative to the end face of sliding under the pressure of the fluid and elastic (or magnetic) compensation mechanism of action to maintain the seal affixed to merge with auxiliary achieve stop leak The shaft sealing device. Commonly used by mechanical seal stationary ring (stationary ring) a rotating ring (ring) 2, the elastic element 3, spring seat 4, 5 set screws, rotating ring secondary seal 6, 8 and stationary ring seals and other auxiliary elements composition, anti-rotation pin 7 is fixed on a stationary ring gland 9 to prevent rotation. Rotating ring and stationary ring often also based on whether they have the ability to compensate axial ring and called compensation or compensation is part of the mechanical seal ring of high precision mechanical components, there is much to its proper installation and operation of its life impact. We generally in accordance with the Ministry of Petroleum and Chemical standards. Installation of the mechanical seal of the pump and the mechanical seal with the technical requirements of the following portions: 1, shaft bending degree: maximum of not more than 0.05 mm; 2, rotor runout: near the sleeve at the seal ring is not more than 0.06 mm; 3, shaft axial runout must not exceed ± 0.5 mm, with a sleeve if allowed sleeve loose; 4, the coupling alignment error: for gear coupling is not greater than 0.08 to 0.10 mm (P2008C), For flexible coupling is not greater than 0.05 to 0.06 mm; (practices end jump <0.05, diameter jump <0.10) 5, gland (stationary ring seat) and seal with the mouth only to the centerline of the shaft concentricity tolerance 0.05 mm , contact pads on the plane and the vertical centerline of the tolerance value of 0.03 to 0.05 mm ISG80-250IA mechanical seals, mechanical seals ISG80-250I if you meet the requirements, the sealed chamber to be processed; 6, the installation ring seals sleeve ends, and installation of stationary ring seal gland (or housing) should be chamfered ends and repair smooth.
