Design and Dynamic Characteristics Research of Hydraulic Compensator in Deep Water

Abstract:

In this paper, mechanical model of traditional bellow type pressure compensator is established. The analysis of static characteristic shows that compensation volume and variation of pressure compensate margin are limited to each other. As a result, it cannot meet the requirements of marine equipment to the underwater hydraulic power. Therefore, a new type of pressure compensation unit is developed, it has advantages of big volume compensation and almost constant pressure compensate margin, it solves the core technical problem of deep-water balancing hydraulic power. The simulation results show that this new type of pressure compensator can satisfy the design requirements and improve the working depth of underwater hydraulic systems sharply.
