   1, static ring gland must have sufficient strength, even when tightening the screws to ensure that its end and the axis perpendicular.
    2, sealed pipe to be kept smooth; prohibited dry friction.
    3, to carry out static pressure test to observe whether there is leakage.
    4, the use of temperature over 80 ℃ should be used to force the way to seal the cooling.
    5, after installation, hand gently press the ring, should be flexible and have a certain flexibility; manual turning, should be free to operate.
    6, the installation of the main shaft radial runout should be ≤ 0.04mm (0.06mm), axial movement of ≤ 0.3mm, and according to the requirements of the processing axis and the corresponding parts of the static ring.
    7, boot test run, pay attention to whether the abnormal sound.
   8, the installation is strictly prohibited collision, brutal beat, friction surface should be absolutely clean.
    9, sealed cavity, shaft, machine seals the parts should be clean, no pollution, bumps, scratches, especially to prevent impurities, dust, particles into the sealed cavity.
