Reasons for modification of mechanical seals in high-temperature melt pumps
In order to make the high temperature polymer melt pump in good operating condition, reduce the frequency of downtime maintenance, and then reduce the number of high temperature melt pump lifting loads, from the extension of the service life of the mechanical seal to start, the high temperature melt pump before the implementation of the technical transformation of the mechanical seal. The use of welded bellows mechanical seal, reduce the leakage point of the seal, improve the service life of the seal. For the transformation of high-temperature extruder melt pump mechanical seal deficiencies, Zhengzhou BATTE melt pump manufacturers from the following four points of analysis and elaboration.
1, O-ring or packing stress release after long-term use, reducing the holding force on the sleeve, thus causing high temperature melt gear pump leakage.
2, high-temperature melt pump working environment for a long time at 250 ℃ or more, on the O-ring or packing materials put forward high requirements, easy to cause aging, shorten the service life of the seal.
3, for the seal with sealing liquid work, in the installation of the initial sealing liquid can not run in time, high temperature melt pump pump body temperature, resulting in rapid expansion of the seal graphite packing ring, when the sealing liquid operation, the seal cavity temperature is reduced, graphite ring contraction, and graphite ring gland bolt preload is not enough to compensate for the contraction of the graphite ring deformation, resulting in leakage of the seal.
4, this structure of the mechanical seal on the installer's technical level puts forward high requirements, in the installation is not easy to accurately locate, easy to cause the moving ring deflection, resulting in high temperature melt pump seal leakage.
