Treatment of the expansion phenomenon of the sealing ring in the reverse osmosis equipment

Nov 24, 2020

In the water treatment equipment, the reverse osmosis equipment in order to realize the sealing and isolation of each section in the membrane shell, the membrane shell needs three types of sealing rubber rings. In order to reduce the installation resistance, clean water or glycerin should be applied to the surface of each sealing ring during installation. Special attention should be paid to the use of petroleum jelly or other petroleum-based grease as the lubricant, otherwise it will cause the cracking of the fresh water pipe, especially the expansion of the sealing rubber ring. The expansion of the apron generally does not directly affect the operating effect of the system, but it will affect the reloading of the system after unloading, that is, the apron that expands during loading is difficult to enter the slot.
