Thrust ring is a FRP membrane shell fittings, is a circular piece, one side covered with carbon steel filter to reduce wear alloy, the lower part of the thrust ring in the middle of the stainless steel membrane shell has a convex tail on the outside, the device is embedded in the FRP membrane shell groove to avoid rolling thrust ring. The thrust ring has the effect of controlling the directional void of FRP membrane shell.

Matters needing attention

1. Both ends of FRP membrane shell should be equipped with thrust rings. If there is a short one, it should be installed at the outlet of concentrated water first.

2. When installing the device, please put the big head on the side of the membrane and the small head on the side of the end cover.

3. The thrust ring is installed at the outlet of concentrated water from the membrane shell, and the inlet end may not be equipped with the thrust ring.

4. Considerations for installing two thrust rings are as follows

Water quality is complex, so forward and reverse scouring are added.

Water quality is complex, so forward chemical washing and counter chemical scouring are added.
