摘　　要：从功率损失的角度推导出油箱中温度随时间变化的公式;同时推导出油管、阀口和液压泵中温升公式。这些公式与实际系统的测试结果基本相符,对液压系统设计计算有参考价值。In this paper,a formula that temperature wit h the time change in oil tank from the power loss is presented;meanwhile,oil pipe,valve scoop and hydraulic pump warm to raise formulae are also presented .These formulae conform to the test result of the prctical system basically,an d have reference value to the design and calcu lation of the hydraulic pressure system.
