Mechanical seal manufacturers to teach you how to correct the installation of single mechanical seal?

Mechanical seal manufacturers to teach you how to correct the installation of single mechanical seal? 2018 - 5 - 23 mechanical seal manufacturers to teach you how to correct the installation of single mechanical seal? Mechanical seal installation order, after completion of the preparations for the installation, can be in a certain order to implement installation, complete static component within the end cover installation and rotating parts installed on the shaft, the final complete sealing combination installation as a whole. To 1 within centrifugal pump with one end face of the balance type mechanical seal, for example, introduces its installation order is as follows: 1. The installation of stationary part will stop pin ( 1) Insert the corresponding hole sealing end cover, and then the static ring auxiliary seal ring ( 2) From the static ring ( 3) Set into the tail, such as it 'V', pay attention to the direction of installation, thus o-rings, is not to roll. Then, make the stop pin on the reverse of the static ring groove on the stop pin in sealed inside the end cover. Stop pin height to fit, should with static environmental leave 1 ~ 2 mm gap, not on the top of the static ring. Finally, the measured static ring to seal end of the end cover from A. After the static ring is installed in the end cover, also check the seals and the center line of the end cover of flatness of verticality and seal face. Of transporting medium liquid hydrocarbon pump, vertical degree of error is not greater than zero. 02 mm, oil and other media can be controlled in 0. 4 mm or less. 2. Determine the installation position of spring seat on the shaft determine the installation position of spring seat, should be good in adjusting the rotating shaft and conducted on the basis of the relative position of the seal chamber shell. End of the first in the sealed cavity pump shaft correctly draw a reference line. Then, according to seal assembly drawing marked seal working length, by the spring seat position size to adjust the amount of compression spring to design specified value. The spring seat position size ( See figure 1) Can press type concluded: B = L - ( + S) Type: B - — Spring 座背 to baseline distance L - — Rotating parts working position total height, L = L '- H; H— — Amount of spring compression; A— — Static ring after assembly into the sealing end cover, the distance from the static ring end face to the end of the end cover; S— — End cover sealing gasket thickness. 3. Rotating parts assembly will spring ( 8) At both ends, respectively, set in the spring seat ( 9) And the ring ( 7) , and make smooth on both ends of the spring and the ring on the spring seat and on a flat surface on tight. Then ring auxiliary seal ring ( 5) Into the ring, 4) In combination with the ring as a body, then will be assembled the woolly on axis ( Or collar) , make the position of the spring 座背 alignment rules, several times evenly twist nail screw tightly ( 10) , with the hand backward compression ring, look to whether can the axial float. 4. Stationary parts installed components will be good static parts of seal end cover is installed on the seal cavity, the end cover uniform compression, shall not be loaded partial with feeler check the end of the end cover and seal cavity gap, the error is not greater than zero. 04mm。 Check the end cover and static ring for shaft radial clearance, the error of each point along the circumference is not greater than zero. 1mm。 Click more mechanical seal manufacturers information: /
