AI Technical Summary

Technical Problem

The existing internal floating roof lacks an effective guiding structure during use, which causes fluctuations in the liquid level, leading to the floating roof shifting or jamming, making it difficult to operate stably.

Method used

The system employs guide wheels and guide grooves to provide precise guidance, and a combination of sealing gaskets and springs ensures a tight seal, limits floating roof offset, and improves stability.

Benefits of technology

It enables the vertical lifting and lowering of the internal floating roof, reduces jamming, improves sealing performance, and reduces oil and gas evaporation.
