挖掘机的操作要求及如何排除故障

日期:2019-03-22   来源:http://www.txkql.com
操作挖掘机作业时与行驶中的要求
Requirements in Operation and Driving of Excavators
操作前应发出信号,工作时要注意选择和创造合理的工作面。严禁将挖掘机同时布置在两个开挖面上。严禁在电线及其他高空装置下作业,禁止工作时调整发动机、调速器、液压系统及电气系统。严禁用铁锹打碎或打碎固体物体。
Before operation, signal should be sent out. When working, attention should be paid to selecting and creating reasonable working face. It is strictly forbidden to place excavators on two excavation faces at the same time. It is strictly forbidden to work under wires and other high-altitude devices. It is forbidden to adjust engines, governors, hydraulic systems and electrical systems while working. It is strictly forbidden to smash or break solid objects with spades.
操作挖掘机作业时与行驶中的要求
Requirements in Operation and Driving of Excavators
严禁用斗杆或铲斗油缸举升挖掘机。禁止用采矿臂对侧面重量进行拖拖,严禁在突然下降时挖掘工作装置。卸料时,应尽量保持桶内的最低水位,不触及车内任何部分,严禁在车内过桶。
It is strictly forbidden to use bucket rod or bucket cylinder lifting excavator. It is forbidden to drag the side weight with the mining arm, and to excavate the working device when it suddenly drops. When unloading, the lowest water level in the barrel should be kept as far as possible, and no part of the car should be touched. It is strictly forbidden to cross the barrel in the car.
液压挖掘机正常工作时,液压油温度应在50~80度之间。在机械使用前,如果温度低于20度,应预热。达到或超过80度时,应停止冷却。挖掘机行走时,由专人指导,距高压线不少于5米。禁止向后走。
When the hydraulic excavator works normally, the temperature of hydraulic oil should be between 50 and 80 degrees. Before the machine is used, if the temperature is below 20 degrees, it should be preheated. Cooling should be stopped when the temperature reaches or exceeds 80 degrees. When the excavator is walking, it is guided by a special person and not less than 5 meters away from the high-voltage line. It is forbidden to go backwards.
下坡行走应低速、匀速、无滑行、变速;挖掘机的位置和路线应与道路、沟、基坑保持安全距离。挖掘机停在斜坡上,铲斗必须放在地面上,所有的操作杆都放置在中间位置;工作结束时,机身应转动,铲斗将被放置在地面上,所有操作杆将处于空档位置。各位置制动器的制动,关闭机门和车窗,司机可以离开。
Downhill walking should be low-speed, uniform, non-taxiing, variable speed; the location and route of excavators should be kept at a safe distance from roads, ditches and foundation pits. When the excavator stops on the slope, the bucket must be placed on the ground, and all the operating rods should be placed in the middle position. At the end of the work, the fuselage should rotate, the bucket will be placed on the ground, and all the operating rods will be in the neutral position. Brake in all positions, close the doors and windows, and the driver can leave.
挖掘故障故障的机会是必需的,在筛选问题需要挖掘机故障排除之前,在开始故障排除前确认相关事项,下面是几个项目,我需要在任何故障排除前确认。整机操作无需手柄,大臂、小臂、桶不动。操作检查:旋转和行走同时操作,原因分析:如果转动和行走没有运动,安全杆可能有故障。
It is necessary to dig out the opportunity of failure. Before screening the problem, we should confirm the relevant items before starting the troubleshooting. Here are several items. I need to confirm before any troubleshooting. The whole machine operates without a handle, and the arms, arms and barrels do not move. Operational Inspection: Rotation and walking are operated simultaneously. Reason analysis: If there is no movement in rotation and walking, the safety rod may be faulty.
修理建议:修理安全杆电磁阀。如果连接电源不能正常工作,可能是线圈烧毁或阀芯卡死,需要更换电磁阀。电磁阀能正常工作,可能是齿轮泵损坏或先导溢流阀失灵,导致先导回路压力无法建立,需要测量先导压力,确认没有损坏主泵需要更换。
Repair Suggestion: Repair safety rod solenoid valve. If the connecting power supply does not work properly, it may be that the coil is burnt down or the spool is stuck, so the solenoid valve needs to be replaced. The solenoid valve can work normally. It may be the damage of gear pump or the failure of pilot relief valve, which results in the failure of the pilot circuit pressure. It is necessary to measure the pilot pressure and confirm that the main pump is not damaged and needs to be replaced.
大臂、小臂、铲斗油缸回收机外摆是无能为力的;操作检查:测量主溢流阀压力;原因分析:这可能是主溢流阀压力太低,即小负荷将被打开,使液压油直接回到坦克,和工作装置不能发挥其应有的效能;维护建议:调整主溢流阀压力的操作说明。
Outer swing of large arm, small arm and bucket cylinder reclaimer is powerless; operation inspection: measuring the pressure of main relief valve; reason analysis: this may be that the pressure of main relief valve is too low, that is, the small load will be opened, so that the hydraulic oil will return to tank directly, and the working device can not play its due role; maintenance suggestions: operation instructions for adjusting the pressure of main relief valve.
大臂,小臂油缸回收机外,颤抖的动作慢;操作检查:确认工作模式、发动机转速,并测量先导压力;原因分析:由于操作设备不足的流动速度慢,先导压力过小,阀芯不能开启所有;模式选择是微操作或操作简单,从而降低发动机转速,减少了主泵的流量。流量控制阀打开或打开并卡住。
Outside the big arm and the small arm cylinder reclaimer, the shaking motion is slow; Operation check: confirm the working mode, engine speed and measure the pilot pressure; Reason analysis: due to the lack of operating equipment, the flow speed is slow, the pilot pressure is too small, the valve spool can not open all; Mode selection is micro-operation or simple operation, which reduces the engine speed and reduces the flow rate of the main pump.  The flow control valve is opened or opened and jammed.

维修建议:调整先导压力到操作手册。选择正确的工作模式,无法选择模式,或导频指示器已切换,但发动机转速和流量不会改变,故障排除控制器将失败。流量电磁阀处于工作状态。
Maintenance advice: adjust pilot pressure to operation manual. The correct mode of operation can not be selected, or the pilot indicator has been switched, but the engine speed and flow will not change, and the troubleshooting controller will fail. Flow solenoid valve is in working state.
