想必拥有挖机设备或操作过挖机的朋友对不能启动的问题都不陌生,遇到问题后都是找维修站,关于故障维修的相关事项您了解吗?下面小编就为您简单讲讲。
The friends who own the excavator or have operated the excavator must be familiar with the problem that the excavator cannot be started. After encountering the problem, they always go to the maintenance station. Do you know anything about troubleshooting? Here is a brief introduction.
长臂挖掘加长臂挖掘机机施工完毕停入场地,长时间闲置或者经过雷雨之后再启动时,发现扭动开关之后长臂挖掘机没有反应,先应考虑蓄电池是否有电或电源总开关是否正常,维修人员用2根导线分别接在蓄电池的正、负极,将2根导线的另一端进行触碰,发现有较强的火花出现,可判断蓄电池有电。
When the long arm excavator stops at the site after construction and is idle for a long time or starts after thunderstorm, it is found that the long arm excavator does not respond after twisting the switch. First, consider whether the battery has electricity or whether the main power switch is normal. The maintenance personnel connect two wires to the positive and negative electrodes of the battery respectively, and touch the other end of the two wires. Strong sparks are found, It can be judged that the battery is charged.

为了判断电源总开关是否良好,将蓄电池负极直接接在机体上试机,仍然不能启动,但仪表灯有电,说明电源总开关正常,经分析可能是电子继电器故障,为此用外接电源直接连接启动机的正、负极启动试机,发动机顺利启动,由此可断定电子继电器损坏,更换电子继电器后,再次试机,故障消失。
In order to judge whether the main power switch is in good condition, connect the negative pole of the battery directly to the machine body for test run, but the machine still cannot be started, but the instrument lamp is powered, which indicates that the main power switch is normal. After analysis, it may be an electronic relay fault. Therefore, use an external power supply to directly connect the positive and negative poles of the starter to start the test run, and the engine starts smoothly. From this, it can be concluded that the electronic relay is damaged. After replacing the electronic relay, try the machine again, and the fault disappears.
其他原因:
Other reasons:
(1)气温太低,机油粘度过大。冷却系加注热水,使用起动预热,使用规定牌号机油。
(1) The temperature is too low and the oil viscosity is too high. The cooling system shall be filled with hot water, preheated by starting, and oil of specified brand shall be used.
(2)燃烧室或气缸中有水。检查,修复,更换。
(2) Water in combustion chamber or cylinder. Check, repair and replace.
