In the repair of mechanical seals, 85% of the seal failure is not caused by wear, but before the wear has been leaked.
① sealing is good. Mechanical seals have the East ring seal ring, static ring seal and seal the end of the three sealing parts, of which East seal ring and static ring seals belong to the static seal, the general sealing
At present, in the production safety requirements and environmental protection requirements, the use of mechanical seals has become more and more extensive, industrial
The rest of the leakage intuitively difficult to identify and judge, in the long-term management, maintenance practice on the basis of the leakage symptoms of observation, analysis, research, in order to come to a correc
In modern industrial equipment, the sealing pair is often used as an important supporting pair of the host.
1.The sealing surface of the main seal ring and the shaft or sleeve must be wiped with a little oil for installation, and in the case of the taboo oil, some clean water or sealing medium can be put on the concrete situat
Mechanical seal is a kind of precision device, its sealing effect and service life depend not only on design, manufacture and correct selection, but also on the installation and cleaning of seals and operating conditions
1.The radial runout of the installed seal spindle shall be ≤0.04mm (0.06mm), the axial channeling momentum ≤0.3mm, and the corresponding parts of the machining shaft and the ring seat are installed according to the stand
Each type of machine seal can only be used in the specified range to effectively play a role, improper selection will lead to a significant reduction in sealing performance, shorten life expectancy, or even failure.
(1) Comprehensive inspection of mechanical seals, as well as ancillary equipment and pipeline installation is complete, whether meet the technical requirements.
1. In the removal of mechanical seals to be careful, strictly prohibit the use of hammer and flat shovel, so as not to damage the sealing elements. Can do a pair of wire hooks, in the direction of self-financing into the
