大型船舶调距桨液压系统温度控制分析*

摘要

This paper analyzes the thermal problems about the hydraulic system for a controllable pitch propeller in the condition of high flow and introduces the thermal-dynamic properties of the hydraulic system for controllable pitch propeller. Applying the average oil temperature method, this paper evaluates the balanced temperature of the hydraulic system. And then the thermal-hydraulic model is established to analyze the thermal-dynamic properties of the hydraulic system in different conditions by using AMESim engineering software.%　　针对船舶调距桨液压系统大流量下的温度控制问题，分析了船舶调距桨液压系统热力学特性，采用平均油温法估算液压系统平衡温度，建立了某船舶调距桨液压系统温度计算模型，得到了在不同海水冷却端流量、海水冷却端温度以及环境温度等情况下液压系统的温升规律，为系统设计提供理论依据。
