The main component of the pressure compensator is the rolling diaphragm. The rolling diaphragm is a layer of rubber and a layer of cloth. A single rubber material cannot resist seawater and Hydraulic oil at the same time.
GENERAL SEALTECH LIMITED designed a Rolling diaphragm with two layers of rubber and one layer of cloth. The inner side NBR (oil resistant) and the outer side CR (seawater resistant). The service life of the rolling diaphragm based on this design is increased by 100%. This design has been applied to some deep-sea equipment and has proved the feasibility and effectiveness of the design.
