1) must be working condition and the host appropriate choice models of mechanical seal and material matching, to ensure the normal operation of sealing machine and service life.

2) NSK bearing installation mechanical seal parts of the axis (collar) of the radial beat tolerance than should be 0.04 mm, rotor shaft to channeling momentum than 0.1 mm.

3) installation mechanical seal of the static sealing ring cover (or shell), the orientation of the perpendicular axis face than 0.04 mm.

4) mechanical seal in the installation, must will axis (collar), seal chamber body, sealed cover and mechanical seal itself clean, prevent any impurity into the sealing parts.

5) SKF bearing when transport medium temperature is on the high side, too low, or containing impurities particle, inflammable, explosive, toxic, must refer to mechanical seal related standards, adopt corresponding resistance sealing, washing, cooling, measures such as filtering.

6) mechanical seal installation, proper lubrication. According to product installation instructions, INA bearing to assure the mechanical seal installation dimensions.

7) equipment in operation must be filled with media before, in order to prevent dry friction and make the seal failure.

 
8) NACHI bearing samples single spring drive mechanical seal, should choose reasonable spring to spin, general from static ring end look, shaft to clockwise, choose dextral spring. Otherwise, choose left spring.
