Zhejiang lifting platform legs have oil leakage phenomenon, indicating the presence of external leakage of hydraulic circuits, each circuit element seal fittings are easy to cause adverse external leakage. After inspection, analysis, excluding the causes of the pipeline that is due to oil leakage outside the horizontal leg of the cylinder piston rod with oil caused. Horizontal leg cylinder piston rod seal is a Y-ring.
Under normal circumstances, Zhejiang lifting platform, YX-ring lip edge of the follower is better, not only friction is small, and its "wipe" 'Xu l students well. However, YX-ring sudden pressure of the moment, due to the internal pressure of the squeeze effect had a chance to produce the phenomenon of self-sealing, adhesion in the piston rod out of the oil may still be excessive, causing the piston rod outer when the oil layer with a stretched thickening. Reduction in the rod when the oil can be scraped off the dust ring part, stuck in the rear piston rod, with fluid retention gradually gathered, forming droplets falling from the rod surface.
Zhejiang lifting platform in order to ensure that the "Erase" oil capacity YX-ring edge of the lip, on the supporting base structure of the buffer length is set longer, the pressure oil through here have a certain pressure drop and a buffer, then applied to YX -ring place. In addition, after the addition of a Yx-ring. -Ring, next to "wipe" the piston rod is too thick oil. Tests show that the improved sealing device eliminates the horizontal leg cylinder piston rod with oil phenomenon.
Improved cylinder Zhejiang lifting platform not only improves the permeability phenomenon lift their cleanliness, but also provides users with a convenient and often a small detail to determine a company's level of understanding for human products, and therefore, this also enough to see the product of careful business, responsible for the extent of the user.
