hot mechanical seals During the installation process
Hot mechanical seal installation, the use of technical methods:
(1) the radial runout of the shaft should be ≤ 0.04 mm, the axial movement is not allowed to more than 0.1 mm;
(2) the sealing parts of the equipment in the installation of thermomechanical seals should be kept clean, sealed parts should be cleaned, sealed end intact, to prevent miscellaneous mechanical density
Sealing and dust into the sealed parts;
(3) in the installation process tight water pump sealed against the impact, beat, so as not to make the thermomechanical seal friction damage and seal failure;
(4) the installation of the surface in contact with the seal should be coated with a layer of clean mechanical oil, so that the smooth installation;
(5) When installing the static ring gland, tighten the screws must be uniform force to ensure that the static ring end and the vertical axis of the vertical requirements;
(6) after the installation of mobile ring, can make the dynamic ring in the axis of flexible movement, and a certain degree of flexibility;
(7) after the installation of hand wheel moving shaft, shaft should be no sense of severity;
(8) the equipment must be filled with media before running to prevent dry friction and seal failure;
(9) for easy crystallization, granular media, the medium temperature> 80oC, should take the appropriate flushing, filtration, cooling measures, a variety of auxiliary devices please refer to the machine
Seal the relevant standards.
(10) the installation of the surface in contact with the seal should be coated with a layer of clean mechanical oil, pay special attention to the choice of mechanical oil for different auxiliary sealing material,
To avoid causing O-ring oil expansion or accelerated aging, resulting in premature failure of sealing.
