我厂生产的CPCD80A型叉车在使用过程中发现在短时间内液压油温升至100℃以上，造成转向液压缸工作异常，转向器卡死等故障。1液压系统油温过高的分析液压系统产生的热量主要来源于液压元件自身压力损失产生的热量以及执行元件工作时产生的热量。现对液压系统作如下分析：(1)CPC
The CPCD80A forklift truck produced by our factory found that the hydraulic oil temperature rose to over 100 ℃ in a short period of time during use, causing the steering cylinder to work abnormally and the steering gear stuck and other faults. A hydraulic system analysis of high oil temperature The heat generated by the hydraulic system mainly comes from the pressure loss of hydraulic components and the heat generated by the work of the implementation of components. The hydraulic system is now analyzed as follows: (1) CPC
