一台平衡重式电瓶叉车使用中发现前围板内的液压油箱通气帽滴漏油,满载快速下降时则不断窜油,当油温较高时更加明显;正常行走、起升过程中则正常。原因分析:由附图(a)知,由于结构的限制使油管3的一段管路必须低于液压油箱通气口6,当叉车运行一段时间后液压油温较高时,其油气会通过通气口6排出,部分油滴会聚集在油管3低于通气口6的管段,如油管3的阴影部分所示。当起升缸的液压油通过回油法兰5回到油箱4时,将
A counterbalanced battery forklift found in the front panel of the hydraulic tank vent cap drip oil, when the full load rapidly descending when the channeling oil, when the oil temperature is more obvious; normal walking, lifting process is normal. (A), due to structural constraints so that a pipeline tubing 3 must be lower than the hydraulic tank vent 6, when the forklift is running for a period of time when the hydraulic oil temperature is high, the oil and gas will pass through the vent 6, part of the oil droplets will gather in the pipe section 3 below the vent 6, as indicated by the shaded portion of the pipe 3. When the lift cylinder hydraulic oil through the return flange 5 back to the tank 4 will be
