Simulation Analysis on Energy Saving Hydraulic System of Underwater Device Based on AMESim

With higher reliability and good control performance, the valve control hydraulic system based on constant rate pump is used widely in underwater equipment to meet harsh working conditions requirement. However, its high energy loss emphasizes energy supply limitation and restricts the development of novel underwater equipment. Considering high reliability, the energy saving hydraulic system based on constant rate pump is analyzed with AMESim. A variable frequency constant flow hydraulic system model and a valve control system model are built and their controller are designed by simulation. Then its characteristics of energy saving are analyzed. The results show that, compared with the valve control hydraulic system, variable frequency constant flow hydraulic system energy consume has fallen more than 70%. And with the increasing of working depth, more energy is saved. Researching on this paper shown that the energy-saving effect of variable frequency constant flow hydraulic system is well and it can be used to improve performance and reliability of underwater equipment.
