叉车回转的故障及解决方法?

来源:/ 日期:2021-05-06 发布人:hangong

全液压是现代叉车起重机的一个重要发展方向,如液压叉车起重机,其回转传动和运动控制的回转机构,主要取决于液压系统,因此,首先涉及液压系统的回转机构的常见故障。以下是对这方面故障的相关知识的讲解。

Full hydraulic is an important development direction of modern forklift crane. For example, the slewing mechanism of slewing transmission and motion control of hydraulic forklift crane mainly depends on the hydraulic system. Therefore, the common faults of slewing mechanism of hydraulic system are firstly involved. The following is the explanation of the relevant knowledge of this aspect of the fault.
无法使系统压力正常,液压马达故障,电源故障正常输出,维修或更换。减速器故障,影响传动,检查,调整。过载复查,避免过载。溢流阀,手动控制阀故障,检查调整。
Unable to make the system pressure normal, hydraulic motor failure, power failure, normal output, maintenance or replacement. Reducer failure, affect the transmission, inspection, adjustment. Overload review to avoid overload. Overflow valve, manual control valve failure, check and adjust.

不能转动系统压力正常旋转减速机齿轮或蜗轮,蜗杆损坏,检查维修。压力马达柱塞或轴承严重卡住或磨损,检查维修。液压马达输出轴断开并更换。回转液压系统压力低。
Unable to rotate the system pressure normally, rotate the gear or worm gear of the reducer, the worm is damaged, check and repair. The plunger or bearing of the pressure motor is seriously stuck or worn. Check and repair. Hydraulic motor output shaft disconnected and replaced. The pressure of the swing hydraulic system is low.
故障排除方法首先是调整。有两种调整:首先,当有负载时,应在停止旋转,直到重新加载正常时进行调整。其次,压力表用于根据指示手册(旋转压力的大小与模型有关)调节溢流阀的压力;二是液压马达和控制阀检修,更换磨损部件。
The first way to solve the problem is adjustment. There are two kinds of adjustment: first, when there is a load, the rotation should be stopped until the reload is normal. Secondly, the pressure gauge is used to adjust the pressure of the relief valve according to the instruction manual (the rotating pressure is related to the model); Second, hydraulic motor and control valve maintenance, replacement of worn parts.
