旋挖作业人员桩机教育考试试卷,旋挖钻机液压系统、电器维护概要

●工作中和工作后,液压系统处在高温下。操作时,它处在高压状况,因此原本液压系统进行检测和保养时,要更加留意先等频率降下来并积聚掉液压油缸管路中的压力。

During and after operation, the hydraulic system is in high temperature. During operation, it is still in high pressure state, so when checking and maintaining the hydraulic system, pay special attention to wait for the temperature to drop and release the pressure in the hydraulic cylinder pipeline.

●当用力螺塞、螺丝或管道接头时,不要站在部件前面,在更换前,要逐步地松开以激发压内部压力。

When loosening the screw plug, screw or hose connector, do not stand in front of the part. Before disassembling, gradually loosen to release the internal pressure.

●当对液压油路进行检测或保养时,一定要排出空气以激发外部压力。

 When inspecting or maintaining the hydraulic oil lines, be sure to discharge air to release internal pressure.

●液压系统的检测或保养内赛以及:检查液压油油位、更换滤芯和添加液压油。

The inspection or maintenance of the hydraulic system includes: check the hydraulic oil level, replace the filter element and add the hydraulic oil.

●当更换高压管道时,检查O形圈是否受损。如果丢失,进行更改

When removing the high-pressure hose, check the O-ring for damage. If it is damaged, then replace.

●当在有O型圈或密闭垫密封的根部拆卸部件时,要清洗安装表面并用新部件更换。

When disassembling parts with o-rings or gasket seals, clean the mounting surface and replace with new ones.


●当安装管道时,不允许扭曲软管或伸展成小长度的圈。这样受损软管并逐渐减少软管的使用寿命。

When installing the hose, do not twist the hose or bend it into a small diameter ring.This can damage the hose and significantly shorten the life of the hose.


电气系统/Electrical system

●电气设备受潮或电缆的绝缘层损坏是十分危险的。这样产生器电并造成机器故障,不要用水冲洗驾驶室内部。但清洗机器时,注意不要让水进入电气部件。

It is very dangerous for electrical equipment to get damp or the insulation of wires to be damaged. This will cause power and machine failure. Do not flush the inside of the cab with water. But when washing the machine, be careful not to let water enter the electrical components.

●有关电气设备的维护:检查并保护蓄电池液位;更换这些灯管;更换保险丝和变压器等。

Maintenance related to electrical system: check and maintain battery level; replace various bulbs; replace fuses and relays.

●在海滩工作时,要努力清洁电力设备避免腐蚀。

When working at the beach, carefully clean the electrical system to prevent corrosion.

●当加装驾驶室冷风机或其他电气设备时,应将它接到专门的电源接头上,选用的电路不能连接保险丝、起动开关或蓄电池继电器上。

When installing the air cooler or other electrical equipment of driver cab, it should be connected to a special power connector. The selected power source cannot be connected to the fuse, starter switch or battery relay.
