根据计算结果,选用功率为1.2 kW的直流电动机作为驱动风扇的动力,对液压系统进行强制风冷散热,使用效果很好一台FD420型集装箱叉车,工作一段时间后出现了液压系统油温过高的现象,严重时起升缸内泄、缸头油封渗漏。油温高的原因如下:一是原液压系统设计不合理,先天不足。该集装箱叉车液压系统中未安装液压油冷却装置,散热仅靠油箱表面和
According to the calculation results, the DC motor with 1.2 kW power was selected as the power for driving the fan, and forced air cooling was used to cool the hydraulic system. The FD420 container truck worked very well. After working for some time, the oil temperature of the hydraulic system was too high The phenomenon of severe lifting cylinder leakage, cylinder head oil seal leakage. The reasons for high oil temperature are as follows: First, the original hydraulic system design is unreasonable, congenitally inadequate. The container forklift hydraulic system is not installed hydraulic oil cooling device, heat dissipation depends only on the tank surface and
