Design and Performance Analysis of Bidirectional Hydraulic Lock for Water-glycol Medium
摘要
Abstract
Water-glycol,an eco-friendly and flame-retardant hydraulic fluid,sees growing use in special working conditions.However,traditional oil-based hydraulic locks show poor compatibility with it.We theoretically investigate a dedicated bidirectional hydraulic lock for water-glycol media.It uses AMESim to simulate viscosity effects(0～80 mPa·s at 20℃,0%～100%water content)on its performance.For water-glycol with 0%～75%water content,flow capacity correlates negatively with viscosity.Pressure loss exhibits distinct direction dependence and viscosity sensitivity.Leakage increases with rising water content.Pure water(100%water content)behaves differently from water-glycol mixtures.The designed hydraulic lock shows good compatibility in the target viscosity range.It provides theoretical support for water-glycol hydraulic systems in deep-sea operations and lays a foundation for efficiency optimization under multi-viscosity fluid conditions.关键词
