Mechanical seals are high precision mechanical components, there is a big influence on the correct installation and operation of its service life. 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 mechanical seals, runout <0.10) 5, gland (stationary ring seat) and seal with the mouth of the shaft centerline only concentricity tolerance 0.05 mm, flat gaskets in contact with the vertical centerline of the tolerance value of 0.03 to 0.05 mm ISW250-300 mechanical seals, if below standard, sealed chamber to be processed; 6, the installation ring seal sleeve ends, and installation of stationary ring seal gland (or housing) should be chamfered ends and repair smooth. 9, the installation process will never agree with what beat sealing element ISW200-400B direct mechanical seals, when demand beat, it is necessary to use special things were beat, to prevent damage to the sealing element. Installation should seal gently to avoid damaging the seals. 10, when the gland bolts should be tightened evenly to prevent deflection gland section, check the points with a feeler or special tools, the error is not greater than 0.05 mm. Check the gland and the shaft or sleeve diameter with the gap (and concentricity), must ensure uniformity around, checking with a feeler points tolerance is not greater than 0.10 mm. 11, when installing the mechanical seal stationary ring ISW250-315A, first static ring seal trap after the stationary ring back, and then into a sealed cover. Pay attention to the maintenance section of the stationary ring, including the vertical section of the stationary ring and cover the middle line, and the back of the stationary ring groove targeting anti-anti-rotation pin, but contact with each other and not allow anti-rotation pin slot. Make sure to install static ring gland or with a plane parallel to the back cover and seal in place. Should be kept flexible and mobile ring after installation, after the ring is pressed against the spring should be able to automatically bounce back. Mechanical seals, ISW250-315A mechanical seals, pump mechanical seal (certified) to provide the Anguo City Stone yuan Pump Company. Anguo Shi Yuan Pump Co., Ltd. (www.shiyuanbeng.com) centrifugal pumps in this area devoted boundless enthusiasm and passion, stone yuan pump has been customer-centric, for customers to create the concept of value, quality, service to win market, and sincerely hope to cooperate with the community to create success, create brilliant.
