一种新型液压管路加热装置的关键元件配型研究

Study on Key Components Matching of a New Hydraulic Pipeline Heating

液压油温关乎到液压元件执行的可靠性以及使用寿命,每一个液压元件均具有适宜的工作温度范围。对于工作于极寒条件下的液压系统,当其暂歇动作时,油温迅速下降,不利于液压元件的再次动作。为满足元件的工作温度,可增设微循环加热装置。该文针对极寒工况下的液压系统微循坏加热装置的关键液压元件选型展开理论建模与分析,探讨并构建了在目标加热功率和短暂时间内,加热阀和蓄能器选型计算方法,该文的研究成果为该装置应用于工程实践提供理论支持。

Hydraulic oil temperature is related to the reliability of the hydraulic components and the service life,each hydraulic components have a suitable operating temperature range.When the hydraulic system which works in the arctic conditions pauses,the oil temperature will decrease rapidly,and it is not conducive to action hydraulic components again.So,in order to meet the working temperature of the components,microcirculation heating device can be added.While,in this paper,the hydraulic components selection of hydraulic system microcirculation heating device under the critical conditions has been studied.The selection methods of heating valve and energy accumulator are discussed and constructed in the target heating power and within a short time.The results provide theoretical support for this device application in engineering practice.
